Bug Hunt uses NetLogo software and simulates an insect population that is preyed on by birds. There are six speeds of bugs from slow to fast and the bird tries to catch as many insects as possible in a certain amount of time. Students are able to see the results graphed as the average insect speed over time, the current bug population and the number of insects caught. There are two variations to try for the predator, one where the predator pursues the prey and one where the predator stays still and captures insects that pass nearby. In the first case the bird catches the slow insects and the faster ones survive, reproduce and pass genes on. The average speed of bug should increase over time. In the second case the faster bugs come near to the bird more often than the slow ones. The slow ones survive more, reproduce and pass their genes on.
Water is a limited resource that we use over and over again. The idea is to teach the science behind the water cycle, where water comes from and is located on the Earth. After research and developing and understanding of conservation students will create a water tower that will collect and store rainwater. Students will also create a Public Service Announcement (PSA) on water conservation.
This online interactive module of 10 pages or frames integrates textual information, 3D molecular models, interactive molecular simulations, and embedded assessment items to guide students in understanding the copying of DNA base sequences from translation to transcription into proteins within each cell. The module divides the exercises in to Day 1 and Day 2 time frames. Teachers can view student assessment responses by assigning the module within a class created within the Molecular Workbench application. This Java-based module must be downloaded to each computer.
This course covers the major topics of mechanics, including momentum and energy conservation, kinematics, NewtonŰŞs laws and equilibrium. The major emphasis is to develop critical analysis, problem solving and scientific reasoning skills by considering numerous different systems and interactions, solving problems and discussion. It uses a systematic approach based on modeling systems by application of basic physics principles, making assumptions, utilizing multiple representations (not just mathematical) in order to become proficient at problem solving. Lab work is required and is designed to help students develop a questioning approach to physical situations, distinguishing the significant behaviors from the less significant behaviors of a system under study.Login: guest_oclPassword: ocl
This is a 21 day unit on the topic of floods. Students will plan and prepare for what might happen in the event of a flood in our area. We have had floods in the past that have affected the Walterville School, its campus, and the surrounding areas. Using this as a springboard, students will discuss the effects of flooding, do research and interview family members who have experienced flooding, and then discuss possible ways to prevent significant damage on the buildings and surrounding areas. They will then design a barrier that could protect an area from damage for a period of time. Students will need materials to conduct experiments. We have listed these in the lesson plan. We have also included a trip to the Leaburg Dam so that students can learn about dams and their uses. We plan on teaching this unit in the fall.
This interactive simulation of human homeostasis provides students the opportunity to explore how our body maintains a stable internal environment in spite of of the outside conditions, within certain limits. This simulation allows students to investigate a phenomenon that may in real life, be dangerous to humans. Students are asked to regulate the internal body temperature of an individual using clothing, exercise, and perspiration. A four- page exploration sheet guides students through the simulation, including a short prior knowledge piece providing information on how to use the simulation and introductory questions. Two separate activities are included: one that helps students understand the how each external factor affects initial body temperature and another that allows students to explore effects on body temperature after one hour. In the second portion of the interactive simulation students try to maintain a stable body temperature when the factors are changed. Students choose the factors of exercise level, sweat level, body position, clothing, and nutrients in terms of both water and food to maintain homeostasis. The simulation generates data tables and graphing during specific time intervals of outside temperature and body temperature. Students may also alter the outside temperature as part of the simulation. Students adjust the exercise level, amount of clothing, and sweating levels. Water level, sugar level, and fatigue level are influenced by the students choices and are illustrated by bar graphs and line graphs. This simulation can provide an introduction to a lesson or unit that explores how body systems interact. This simulation provides a good foundation for continued study of how the body systems interact and would be an excellent starting point for a lesson or unit on this concept. This interactive simulation provides students with a strong introduction to how body systems interact as the simulation illustrates how to maintain body temperature, sugar level and fatigue level and students are made aware of the consequences of not maintaining those levels. The importance of water and food are also emphasized. Students can rerun the simulation making different choices to determine the effects on homeostasis. Student exploration sheets provide guides for different runs with students setting their own parameters for the runs and drawing conclusions from the resulting changes. Teachers can view student assessment responses by assigning the simulation to a class created within the ExploreLearning site. Access to the teachers guide is provided with the free 30 day access and is helpful and complete. Vocabulary of dehydration, heat stroke, homeostasis, hypothermia, and involuntary, voluntary and thermoregulation are explained in detail in the accompanying teachers vocabulary guide.
The lectures introduce a number of topics that are important for IWRM and the modeling exercise. The lectures introduce water management issues in the Netherlands, Rhine Basin, and Volta Basin. The role-play is meant to experience some of the social processes that, together with technical knowledge, determine water management.
Introduction to seismic theory, measurements and processing of seismic data to final focussed image for geological and/or physical interpretation.This course deals with the most important aspects of reflection seismics. Theory of seismic waves, aspects of data acquisition (seismic sources, receivers and recorders), and of data processing (CMP processing, velocity analysis, stacking, migration) will be dealt with. The course will be supplemented by a practical of 6 afternoons where the students will see the most important data-processing steps via exercises (in Matlab).
This Java-based NetLogo model allows students to investigate the chemical and energy inputs and outputs of photosynthesis through an interactive simulation. The simulation is a visual, conceptual model of photosynthesis and does not generate quantitative data. The central concept in the model is the role of chlorophyll in capturing light energy, and this concept is presented without delving into the biochemical details of the photosynthetic reactions. This allows students to focus on the core idea that photosynthesis transforms light energy into chemical energy. Along with exploring the basic process of photosynthesis, students can investigate the effects of light intensity, the day-night cycle (assuming the most common C3 photosynthetic pathway), CO2 concentration, and water availability on the rate of sugar production during photosynthesis. The model highlights the cycling within the chloroplasts between excited and unexcited states as energy is captured and released by chlorophyll. The lesson is written as an introductory learning experience, beginning with the question: What is needed for photosynthesis in a leaf, and what is produced? This resource is best suited as one in a series of learning experiences that either reinforce or extend the concepts addressed here. The model is embedded within an electronic form that provides instructions and guiding questions. Teachers and students should note that the electronic form does not save user data. An important limitation is that the model relies heavily on students visual perception, and this may pose a barrier for some students.
OpenGrade is open-source software for teachers to keep track of grades. It runs on Linux, as well as some other operating systems.
This web simulation allows students to explore adaptive radiation of a fictitious group of birds called Pollenpeepers over a period of 5 million years. A hurricane blows some birds to 3 very different island groups and students identify the changes that take place over time and their causes including different climates, food, competition and predators. Each of the three island groups are compared to the original habitat with respect to topography, temperature, growing season and type of vegetation. Students read about the competition that the birds face when they arrive five million years ago, look at the amount of seeds, insects and flowers present and whether the number of predators is high, medium or low. They can then go forward in time a million years at a time and see the changes that have taken place in the population of pollenpeepers in each of these time periods. Instructions to operate the simulation are included as well as a species gallery where students can explore adaptive radiation in lemurs, Galapagos finches, Hawaiian silverswords, tenrecs and Hawaiian fruit flies.
Population Explosion is a computer simulation which allows students to manipulate factors to see what happens over time to a population of sheep within an enclosed field. As the simulation runs, a graph shows the dynamic relationship between the sheep population size and their primary food resource, grass. Students can control factors such as initial number of sheep, grass regrowth rate, gain from food, and birthrate. Predation is represented by a reaper button which may also be controlled. The speed of the simulation can be set so that students can see more clearly what happens over time, or collect data more quickly, depending on how fast the simulation runs. Directions and a suggested simulation sequence are provided along with prompts so that students can pause and consider their results. A space within the simulation is provided for students to record observations and answers to the prompts. For each step in this suggested sequence, students take a snapshot of graphs they have created and store them in an album. At the end of the activity analysis questions help students connect the activity to wild populations. An optional extension exercise is also suggested.
Our school, Kelly Middle School, is one of the oldest middle school buildings in 4J (primary construction was completed in 1945). Each year we practice earthquake drills. Why? Why should we be concerned about earthquakes? Where might an earthquake occur in the northwest area? Might it be minor or violent? How might this be measured? Is an earthquake a singular event, or a series of events? What increases or decreases an earthquake hazard? Do we have any early-warning systems? Is the school earthquake drill correct? Considering these questions students need to develop an understanding of how to prepare for, and react to an earthquake event. When students are comfortably informed, who should they report to?
In this project, students will use knowledge of electricity and electromagnetism to collaboratively design and test a model of a magnetic recycling sorter. They will evaluate the performance of their models and propose further modifications based on the output of their magnetic device measured in mT using a Vernier probe. They will also physically test their magnets on a model of a conveyor belt containing recyclable items. Students will track their data from both tests, with the ultimate goal of creating the strongest and most effective magnet with given materials. Finally, students will present their findings and proposed final design to peers and community partners involved in the recycling industry. The entire process takes about 6 weeks. The unit is a great fit for standards within energy and engineering & design.

Have you ever wondered what happens to the different stars in the night sky as they get older? The Star in a Box application lets you explore the life cycle of stars. It animates stars with different starting masses as they change during their lives. Some stars live fast-paced, dramatic lives; others change very little for billions of years. The app visualises the changes in mass, size, brightness and temperature for all these different stages.
In order to promote students’ conceptual understanding and learning experience in introductory statistics, a technology task, which focuses on the probability distribution in which means are defined, was created using TinkerPlots, an exploratory data analysis and modeling software. The targeted audiences range from senior high school grade levels to college freshmen who are starting their introductory course in statistics. Students will be guided to explore and discover the movement behaviors of means of a set of numbers randomly generated from a fixed range of values characterized by a predetermined probability distribution. The cognitive, mathematical, technological and pedagogical natures of the task, as well as its association with the statistics education framework based on the Guidelines for Assessment and Instruction in Statistics Education (GAISE) by the American Statistical Association, will be elaborated. A brief discussion on what cognitive design principles this task satisfies will also be provided at the end.
This computer-based learning module engages students in questions that scientists around the world are exploring about Earths climate. They gain an appreciation for how much is not known about the Earth and climate change. The module contains 5 activities; 1) Earths Changing Climates, 2) Interactions Within the Atmosphere, 3) Sources, Sinks, and Feedbacks, 4) Feedbacks of Ice and Clouds, and 5) Using Models to Make Predictions. Each activity provides information in simulations, text, video, or graphic format and the students enter answers to both open-ended and closed questions within the program. Once the students have completed an activity, they can print a report showing all the questions and their answers. The authors estimate the entire module should take 225 minutes.
