In this activity, students will review and evaluate the ways land is covered and used in their local community. They will also consider the environmental effects of the different types of land use. Students will act as community planning engineers to determine where to place a new structure that will have the least effect on the environment.

In this activity, students work as engineers to build and observe a model landfill. They will understand the process and pitfalls of the use of landfills as a method for the waste disposal.

From selfies to social media, many of us create unique online identities for ourselves, and our students are no different. But do kids always understand how others might perceive what they post? Help your students think critically about the online identities they're creating.

This lesson plan introduces students to Thomas Edison's life and inventions. It asks students to compare and contrast life around 1900 with their own lives and helps students understand the connections between the technological advancements of the early twentieth century and contemporary society and culture.

Students are introduced to an engineering challenge in which they are given a job assignment to separate three types of apples. However, they are unable to see the color differences between the apples, and as a result, they must think as engineers to design devices that can be used to help them distinguish the apples from one another. Solving the challenge depends on an understanding of wave properties and the biology of sight. After being introduced to the challenge, students form ideas and brainstorm about what background knowledge is required to solve the challenge. A class discussion produces student ideas that can be grouped into broad subject categories: waves and wave properties, light and the electromagnetic spectrum, and the structure of the eye.

This 10-minute video lesson shows that three points uniquely define a circle and that the center of a circle is the circumcenter for any triangle that the circle is circumscribed about.

In this lesson, students study issues related to independence and notions of manliness in Ernest Hemingway’s “Three Shots” as they conduct in-depth literary character analysis, consider the significance of environment to growing up and investigate Hemingway’s Nobel Prize-winning, unique prose style. In addition, they will have the opportunity to write and revise a short story based on their own childhood experiences and together create a short story collection.

The purpose of this task is to help students understand composing and decomposing ones, tens, and hundreds. This task is meant to be used in an instructional setting and would only be appropriate to use if students actually have base-ten blocks on hand.

This task allows the students to compare characteristics of two quadratic functions that are each represented differently, one as the graph of a quadratic function and one written out algebraically. Specifically, we are asking the students to determine which function has the greatest maximum and the greatest non-negative root.

This task illustrates A-SSE.1a because it requires students to identify expressions as sums or products and interpret each summand or factor.

Although this task is quite straightforward, it has a couple of aspects designed to encourage students to attend to the structure of the equation and the meaning of the variables in it. It fosters flexibility in seeing the same equation in two different ways, and it requires students to attend to the meaning of the variables in the preamble and extract the values from the descriptions.

In this lesson, students begin to focus on the torque associated with a current carrying loop in a magnetic field. Students are prompted with example problems and use diagrams to visualize the vector product. In addition, students learn to calculate the energy of this loop in the magnetic field. Several example problems are included and completed as a class. A homework assignment is also attached as a means of student assessment.

This art history video discussion looks at Thutmose's "Model Bust of Queen Nefertiti", New Kingdom, 18th dynasty, c. 1340 BCE, limestone and plaster (Egyptian Museum and Papyrus Collection/Neues Museum, Berlin).

This is a simple task about interpreting the graph of a function in terms of the relationship between quantities that it represents.

Los estudiantes aprenden acerca de la biomímisis y el proceso de diseño técnico al diseñar y construir un modelo del pie de la perdiz.

To learn about the concept of center of mass, students examine how objects balance. They make symmetrical cut-outs of different "creatures" and experiment with how they balance on a tightrope of string. Students see the concept of center of mass at work as the creatures balance.

ile patterns will be familiar with students both from working with geometry tiles and from the many tiles they encounter in the world. Here one of the most important examples of a tiling, with regular hexagons, is studied in detail. This provides students an opportunity to use what they know about the sum of the angles in a triangle and also the sum of angles which make a line.

This task aims at explaining why four regular octagons can be placed around a central square, applying student knowledge of triangles and sums of angles in both triangles and more general polygons.

This short video and interactive assessment activity is designed to give fourth graders an overview of time conversion between words and numbers.
