"Concept Development Studies in Chemistry" is an on-line textbook for an Introductory General Chemistry course. Each module develops a central concept in Chemistry from experimental observations and inductive reasoning. This approach complements an interactive or active learning teaching approach.

For a semester-length course, all seven chapters can be covered. For a shorter course, the book is designed so that chapters 1, 2, and 5 are the only ones that are required for continuity; any of the others can be included or omitted at the instructor’s discretion, with the only constraint being that chapter 6 requires chapter 4.

With the help of simple, teacher-led demonstration activities, students learn the basic concepts of heat transfer by means of conduction, convection, and radiation. Students then apply these concepts as they work in teams to solve two problems. One problem requires that they maintain the warm temperature of one soda can filled with water at approximately body temperature, and the other problem is to cause an identical soda can of warm water to cool as much as possible during the same thirty-minute time interval. Students design their solutions using only common, everyday materials. They record the water temperatures in their two soda cans every five minutes, and prepare line graphs in order to visually compare their results to the temperature of an unaltered control can of water.

Experiment with conductivity in metals, plastics and photoconductors. See why metals conduct and plastics don't, and why some materials conduct only when you shine a flashlight on them.

Students make a simple conductivity tester using a battery and light bulb. They learn the difference between conductors and insulators of electrical energy as they test a variety of materials for their ability to conduct electricity.

CSDE Model Curricula Quick Start GuideEquitable and Inclusive Curriculum  The CSDE believes in providing a set of conditions where learners are repositioned at the center of curricula planning and design. Curricula, from a culturally responsive perspective, require intentional planning for diversity, equity, and inclusion in the development of units and implementation of lessons. It is critical to develop a learning environment that is relevant to and reflective of students’ social, cultural, and linguistic experiences to effectively connect their culturally and community-based knowledge to the class. Begin by connecting what is known about students’ cognitive and interdisciplinary diversity to the learning of the unit. Opposed to starting instructional planning with gaps in students’ knowledge, plan from an asset-based perspective by starting from students’ strengths. In doing so, curricula’s implementation will be grounded in instruction that engages, motivates, and supports the intellectual capacity of all students.Course Description: Three-Dimensional Learning shifts the focus of the science classroom to environments where students use disciplinary core ideas, crosscutting concepts with scientific practices to explore, examine, and explain how and why phenomena occur and to design solutions to problems. Three-dimensional learning helps students build their research, communication, and analytical thinking skills.More informational regarding Three-Dimensional learning can be accessed at the following address:What exactly IS three-dimensional learning? | Teaching ChannelEach year, students in Connecticut should be able to demonstrate greater capacity for connecting knowledge across, and between, the physical sciences, life sciences, earth and space sciences, and engineering design. The kindergarten year is unique as it is the formal beginning of NGSS learning pedagogy. However, CSDE has aligned our Pre-K learning standards to follow similar hands-on, student-centered methodology when developing Pre-K units of study. Therefore, students will begin to form deeper connections between concepts previously learned in Pre-K, such as collecting evidence and drawing conclusions, understanding relationships between objects, and critical thinking that leads to designing effective solutions for problems. Upon completion of Grade K, students should have a deeper understanding of: A review of what happens to objects as they are pulled or pushed.A basic understanding of what plants and animals need to survive.Explain how the weather today different than it was yesterday.Aligned Core Resources: Core resources is a local control decision.  Ensuring alignment of resources to the standards is critical for success. Alignment of all content materials across the grades and vertically in the grade band must be communicated to all staff. Additional Course Information:  NGSS has unique features. To better understand the make-up of NGSS visit the following website for a more detailed break-down of the CT Science standards from which this curriculum was based.  Nextgenscience  Assessment Information: There are many ways to assess student learning. Besides annual statewide summative testing, the Connecticut State Department of Education has developed NGSS Interim Assessment blocks specific to the grade 3 – 5 grade band. These can be accessed through the CSDE Website in the Performance Office tab. Many websites also offer assessment materials aligned to the NGSS, specifically through the NSTA, and Defined Learning.   ELA/Math Transferable Skills Addressed in the Course:  The following Practices Venn Diagram illustrates the connections and commonalities in the major content areas. This diagram attempts to cluster practices and capacities that have similar tenets and/or significant overlaps in the student expectations. Likewise, we have placed practices and capacities within the disciplinary domains if there was not a significant overlap or relationship to another discipline. One could argue certain practices/capacities could be placed in other positions within the Venn diagram. These placements are not definitive and the intention of the standards documents may not have conceptualized the three disciplinary areas In this manner. ​

Unit Overview/Summary - FOCUS:  Summary The bundle organizes performance expectations around the relationship between the needs of different plants and animals and the places they live. Instruction developed from this bundle should always maintain the three-dimensional nature of the standards but recognize that instruction is not limited to the practices and concepts directly linked with any of the bundle performance expectations. Connections between unit Disciplinary Core Ideas (DCIs)  The concept that all animals need food and plants need water and light (LS1.C as in K-LS1-1) connects to the idea that living things need water, air, and resources from the land, and they live in places that have the things they need (ESS3.A as in K-ESS3-1). These ideas also connect to the concept that plants and animals (including humans) can change the environment to meet their needs (K-ESS2-2). The concept that humans use natural resources for everything they do (ESS3.A as in K-ESS3-1) connects to the idea that the things people do to live comfortably can affect the world around them, but they can make choices that reduce their impacts on the land, water, air, and other living things (ESS3.C as in K-ESS2-2 and K-ESS3-3) Weather—which is the combination of sunlight, wind, snow or rain, and temperature in a particular region at a particular time (ESS2.D as in K-ESS2-1) —connects to the idea that living things need water (ESS3.A as in K-ESS3-1) and the idea that plants need light (LS1.C as in K-LS1-1). Also, the concept of the needs of living things connects to weather through making observation to notice and describe patterns as: observations can be used to describe the patterns of what plants and animals need (K-LS1-1) and observations and measurements of weather conditions can be used to describe and record the weather and to notice patterns over time (ESS2.D as in K-ESS2-1). The concepts of weather and patterns of weather (ESS2.D as in K-ESS2-1) also connect to the idea that some kinds of severe weather are more likely than others in a given region (ESS3.B as in K-ESS3-2). The idea that a situation that people want to change or create can be approached as a problem to be solved through engineering (ETS1.A, K-2-ETS1-1) could connect to several concepts such as plants need water and light to live and grow (LS1.C as in K-LS1-1), humans use natural resources for everything they do (ESS3.A as in K-ESS3-1), or that people can make choices that reduce their impacts on the land, water, air, and other living things (ESS3.C as in K-ESS3-3). These connections could be made through tasks such as designing a solution to the problem of plants in a garden not getting enough water or sunlight or identifying ways to reduce their class’s impact on the local water system. Alternatively, students could be challenged with a different design task involving creating products out of natural resources that are abundant in their area. In both tasks, students need an opportunity to reflect on the situation to be changed and that it can be approached as a problem to be solved through engineering.Unit Science and Engineering Practices (SEPs)Instruction leading to this bundle of PEs will help students build toward proficiency in elements of the practices of asking questions and defining problems (K-ESS3-2 and K-2-ETS1-1); developing and using models (K-ESS3-1); analyzing and interpreting data (K-LS1-1 and K-ESS2-1); engaging in argument from evidence (K-ESS2-2); and obtaining, evaluating, and communicating Information (K-ESS3-2 and K-ESS3-3). Many other practice elements can be used in instruction. Unit Crosscutting Concepts (CCCs)Instruction leading to this bundle of PEs will help students build toward proficiency in elements of the concepts of Cause and Effect (K-ESS3-2 and K-ESS3-3); and Patterns (K-LS1-1 and K-ESS2-1); Systems and System Models (K-ESS2-2 and K-ESS3-1). Many other crosscutting concepts elements can be used in instruction. All instruction should be three-dimensional.

Unit Overview/Summary - FOCUS:  Summary The unit organizes performance expectations around observations of patterns and effects of sunlight. Instruction developed from this unit should always maintain the three-dimensional nature of the standards but recognize that instruction is not limited to the practices and concepts directly linked with any of the bundle performance expectations. Connections between unit Disciplinary Core Ideas (DCIs)  Sunlight warms Earth’s surface. (PS3.B as in K-PS3-1 and K-PS3-2). This concept of sunlight warming Earth’s surface connects to the idea that weather is the combination of sunlight, wind, snow or rain, and temperature in a particular region at a particular time (ESS2.D as in K-ESS2-1). The concept that designs can be conveyed through sketches, drawings, or physical models (ETS1.B as in K-2-ETS1-2) could connect to multiple concepts such as sunlight warms Earth’s surface (PS3.B as in K-PS3-1 and K-PS3-2) and weather is the combination of sunlight, wind, snow or rain, and temperature in a particular region at a particular time (ESS2.D as in K-ESS2-1). These connections could be made through a task in which students must use a representation to convey their design of a structure that will provide a cool place for the students at their school to use when they are outside on a warm day. Students could also engage in a task in which they need to convey the design of an object that would protect them from any negative effects of wind and then reflect on the usefulness of conveying their ideas through representations. Unit Science and Engineering Practices (SEPs)Instruction leading to this unit of PEs will help students build toward proficiency in elements of the practices of developing and using models (K-2-ETS1-2), planning, and carrying out investigations (K-PS3-1), analyzing and interpreting data (K-ESS2-1) and constructing explanations and designing solutions (K-PS3- 2). Many other practice elements can be used in instruction. Unit Crosscutting Concepts (CCCs)Instruction leading to this unit of PEs will help students build toward proficiency in elements of the crosscutting concepts of Patterns (K-ESS2-1), Cause and Effect (K-PS3-1 and K-PS3-2), and Structure and Function (K-2-ETS1-2). Many other crosscutting concepts elements can be used in instruction. All instruction should be three-dimensional.

Unit Overview/Summary - FOCUS:  Summary The unit organizes performance expectations around the topic of pushes and pulls. Instruction developed from this bundle should always maintain the three-dimensional nature of the standards but recognize that instruction is not limited to the practices and concepts directly linked with any of the bundle performance expectations. Connections between unit Disciplinary Core Ideas (DCIs)  Pushing or pulling on an object can change the speed or direction of its motion and can start or stop it (PS2.A as in K-PS2-1 and K-PS2-2). This concept of motion connects to the idea that a bigger push or pull makes things speed up or slow down more quickly (PS3.C as in K-PS2-1). The concept of pushing or pulling on an object (PS2.A as in K-PS2-1 and K-PS2-2) also connects to the idea that when objects touch, or collide, they push on one another and can change motion. (PS2.B as in K-PS2-1) The idea that a bigger push or pull makes things speed up or slow down more quickly (PS3.C as in K-PS2-1) connects to the concept that pushes and pulls can have different strengths and directions (PS2.A as in K-PS2-1 and K-PS2-2). The concept that people measure weather conditions to describe and record the weather and to notice patterns over time (ESS2.D as in K-ESS2-1) connects to the idea that it is useful to compare and test designs (ETS1.C as in K-2-ETS1-3) through data analysis. The ideas that a situation that people want to change or create can be approached as a problem to be solved through engineering (ETS1.A as in K-PS2-2) and that, because there is always more than one possible solution to a problem, it is useful to compare and test designs (ETS1.C as in K-2-ETS1-3) could connect to multiple physical science concepts in this bundle. For example, these concepts could connect to the idea that when objects touch or collide, they push on one another and can change motion (PS2.B as in K-PS2-1) through a task in which students are challenged to work in groups to change the direction or speed of a ball with another object and then test and compare each group’s solution. Alternatively, these engineering concepts could connect to the idea that a bigger push or pull makes things speed up or slow down more quickly (PS3.C as in K-PS2-1) through a different task in which students are asked to pull or push an object in a certain amount of time and then challenged to do it faster. Students could then compare their solutions and reflect on how their pull or push needed to change in order to move the object faster. Unit Science and Engineering Practices (SEPs)Instruction leading to this unit of PEs will help students build toward proficiency in elements of the practices of planning and carrying out investigations (KPS2-1); and analyzing and interpreting data (K-PS2-2, K-ESS2-1, and K-2-ETS1-3).

Unit Overview/Summary - FOCUS:  Summary The unit organizes performance expectations around the theme of seeing objects. Instruction developed from this bundle should always maintain the three-dimensional nature of the standards but recognize that instruction is not limited to the practices and concepts directly linked with any of the unit performance expectations. Connections between unit Disciplinary Core Ideas (DCIs)  The concept that seasonal patterns of sunrise and sunset can be observed, described, and predicted (ESS1.B as in 1-ESS1-2) connects to the idea that objects can be seen if they give off their own light or if there is light to illuminate them (PS4.B as in 1-PS4-2). This idea in turn connects to the idea that some materials allow light to pass through them, others allow only some light through, and others block all the light and create a dark shadow on any surface beyond them, where the light cannot reach (PS4.B as in 1-PS4-3). Unit Science and Engineering Practices (SEPs)Instruction leading to this unit of PEs will help students build toward proficiency in elements of the practices of planning and carrying out investigations (1- ESS1-2 and 1-PS4-3) and constructing explanations and designing solutions (1-PS4-2).

Unit Overview/Summary - FOCUS:  Summary The unit organizes performance expectations with a focus on the theme of observing objects with sight and hearing. Instruction developed from this unit should always maintain the three-dimensional nature of the standards but recognize that instruction is not limited to the practices and concepts directly linked with any of the unit performance expectations. Connections between bundle DCIs The idea that seasonal patterns of sunrise and sunset can be observed, described, and predicted (ESS1.B as in 1-ESS1-2) connects to the concept that the patterns of the motion of the sun, moon, and stars in the sky can be observed, described, and predicted (ESS1.A as in 1-ESS1-1). These ideas also connect to the concept that objects can be seen if light is available to illuminate them or if they give off their own light (1-PS4-2). The concept of how objects can be seen can also connect to the idea that people also use a variety of devices to communicate (send and receive information) over long distances (PS4.C as in 1-PS4-4). Ideas about communication devices also connect to the concept that sound can make matter vibrate, and vibrating matter can make sound (PS4.A as in 1-PS4-1). The engineering design idea that a situation that people want to change or create can be approached as a problem to be solved through engineering (ETS1.A as in K-2-ETS1-1) could be applied to different science concepts, such as to the concept that sound can make matter vibrate, and vibrating matter can make sound (PS4.A as in 1-PS4-1), and to the concept that people also use a variety of devices to communicate (send and receive information) over long distances (PS4.C as in 1-PS4-4). Connections can be made through engineering tasks such as a task in which students identify devices they, or their families, may use that have been created to solve the problem of communicating over long distances, through a task in which students are challenged to create an instrument that uses vibrations to make sound, or through a task in which students try to make something move with vibrations created by sound. Additionally, students could connect these science concepts to the idea that because there is always more than one possible solution to a problem, it is useful to compare and test designs (ETS1.C as in K-2-ETS1- 3). For example, students could test the instruments they created, or they can compare different devices for how well the device allows people to communicate over long distances. Unit Science and Engineering Practices Instruction leading to this unit of PEs will help students build toward proficiency in elements of the practices of asking questions and defining problems (K-2- ETS1-1), planning and carrying out investigations (1-PS4-1 and 1-ESS1-2), analyzing and interpreting data (1-ESS1-1), and constructing explanations and designing solutions (1-PS4-2 and 1-PS4-4). Many other practice elements can be used in instruction. Unit Crosscutting Concepts Instruction leading to this unit of PEs will help students build toward proficiency in elements of the crosscutting concepts of Patterns (1-ESS1-1 and 1-ESS1-2) and Cause and Effect (1-PS4-1 and 1-PS4-2). Many other crosscutting concepts elements can be used in instruction. All instruction should be three-dimensional.

Instruction developed from this unit should always maintain the three-dimensional nature of the standards but recognize that instruction is not limited to the practices and concepts directly linked with any of the unit performance expectations.Connections between bundle DCIsThe idea that seasonal patterns of sunrise and sunset can be observed, described, and predicted (ESS1.B as in 1-ESS1-2) connects to the concept that the patterns of the motion of the sun, moon, and stars in the sky can be observed, described, and predicted (ESS1.A as in 1-ESS1-1). These ideas also connect to the concept that objects can be seen if light is available to illuminate them or if they give off their own light (1-PS4-2).The concept of how objects can be seen can also connect to the idea that people also use a variety of devices to communicate (send and receive information) over long distances (PS4.C as in 1-PS4-4). Ideas about communication devices also connect to the concept that sound can make matter vibrate, and vibrating matter can make sound (PS4.A as in 1-PS4-1).The engineering design idea that a situation that people want to change or create can be approached as a problem to be solved through engineering (ETS1.A as in K-2-ETS1-1) could be applied to different science concepts, such as to the concept that sound can make matter vibrate, and vibrating matter can make sound (PS4.A as in 1-PS4-1), and to the concept that people also use a variety of devices to communicate (send and receive information) over long distances (PS4.C as in 1-PS4-4).Connections can be made through engineering tasks such as a task in which students identify devices they, or their families, may use that have been created to solve the problem of communicating over long distances, through a task in which students are challenged to create an instrument that uses vibrations to make sound, or through a task in which students try to make something move with vibrations created by sound. Additionally, students could connect these science concepts to the idea that because there is always more than one possible solution to a problem, it is useful to compare and test designs (ETS1.C as in K-2-ETS1- 3). For example, students could test the instruments they created, or they can compare different devices for how well the device allows people to communicate over long distances.Unit Science and Engineering PracticesInstruction leading to this unit of PEs will help students build toward proficiency in elements of the practices of asking questions and defining problems (K-2- ETS1-1), planning and carrying out investigations (1-PS4-1 and 1-ESS1-2), analyzing and interpreting data (1-ESS1-1), and constructing explanations and designing solutions (1-PS4-2 and 1-PS4-4). Many other practice elements can be used in instruction.Unit Crosscutting ConceptsInstruction leading to this unit of PEs will help students build toward proficiency in elements of the crosscutting concepts of Patterns (1-ESS1-1 and 1-ESS1-2) and Cause and Effect (1-PS4-1 and 1-PS4-2). Many other crosscutting concepts elements can be used in instruction. All instruction should be three-dimensional.

Unit Overview/Summary - FOCUS:  The unit organizes performance expectations with a focus on the theme of structures and behaviors in organisms. Instruction developed from this unit should always maintain the three-dimensional nature of the standards but recognize that instruction is not limited to the practices and concepts directly linked with any of the unit performance expectations. Connections between unit DCIs The idea of seasonal patterns of sunrise and sunset (ESS1.B as in 1-ESS1-2) can be connected to the idea that plants have different parts (roots, stems, leaves, flowers, fruits) that help them survive and grow (LS1.A as in 1-LS1-1) through the concept of sunlight, which varies by season and is captured by plants, mostly through their leaves so that they can grow and survive. The idea of organism survival also connects to the concept that, in many kinds of animals, parents and their offspring engage in behaviors that help the offspring survive (LS1.B as in 1-LS1-2). This concept connects to the idea that young animals are very much, but not exactly like, their parents (LS3.A as in 1-LS3-1). The engineering design idea that designs can be conveyed through sketches, drawings, or physical models (ETS1.B as in K-2-ETS1-2) could be applied to multiple concepts such as that plants have different parts (roots, stems, leaves, flowers, fruits) that help them survive and grow (LS1.A as in 1-LS1-1) or that animals respond to inputs with behaviors that help them survive (LS1.D as in 1-LS1-1). Connections could be made through tasks such as one in which students are asked to design a structure that mimics a way in which a plant part helps it grow and survive. Students can share their design ideas through sketches, drawings, or physical models. Another connection could be through a task in which students design a device that has different responses for different inputs, and then students can compare their device to an animal’s response to the same inputs. Unit Science and Engineering Practices Instruction leading to this unit of PEs will help students build toward proficiency in elements of the practices of asking questions and defining problems (K-2- ETS1-1), planning and carrying out investigations (1-ESS1-2), developing and using models (K-2-ETS1-2), analyzing and interpreting data (1-ESS1-1), constructing explanations and designing solutions (1-LS1-1 and 1-LS3-1), and obtaining, evaluating, and communicating information (1-LS1-2). Many other practice elements can be used in instruction. Unit Crosscutting Concepts Instruction leading to this unit of PEs will help students build toward proficiency in elements of the crosscutting concepts of Patterns (1-ESS1-2, 1-LS3-1, and 1-LS1-2), Structure and Function (K-2-ETS1-2 and 1-LS1-2), and Cause and Effect (1-PS4-1). Many other crosscutting concepts elements can be used in instruction. All instruction should be three-dimensional.
