Fifth graders connect their knowledge of polygons and polyhedrons. In this geometric shapes lesson, 5th graders identify and classify two- and three-dimensional objects. Students construct a polyhedron out of polygons and describe their...

Students use plastic bottles, water, and condiment packets to simulate how natural gas comes from decaying ocean plants and animals. For this natural gas lesson plan, students also fill out lab packets and answer exit questions.

Twelfth graders solve problems by finding the maximum and minimum. In this calculus lesson, 12th graders analyze certain animals identifying their maximum and minimum points. They also use bubble as part of their real world application...

Students define the maximum and minimum of an equation. For this calculus lesson, students analyze point on a graph and determine when a graph is approaching a maximum or minimum. They take a Quiz after working some review problems.

Students use models and symbols to represent properties of the Pythagorean Theorem. In this right triangle lesson, students connect real jobs to properties of right triangles. They solve word problems applying the correct ratios and...

Learners investigate why cells divide. For this cell size lesson plan, students observe how far a solution travels into 3 different size model cells of agar. They answer questions about the most effect movement of "nutrients" into the...

Students identify the ratios of different triangles. In this geometry lesson, students identify the similarity and differences of triangles. They use the navigator to move the sides of the triangle around.

Sixth graders examine the Lewis and Clark Expedition. In this plant discovery lesson, 6th graders put in chronological order the plant discoveries of Lewis and Clark. Students understand the characteristics of leaves and find the area of...

Students define vocabulary related to geometry and calculate the volume. In this geometry lesson, students calculate flow rates, and volume as it relates to a water plant facility. They calculate the volume of three dimensional shapes...

Pupils investigate the formulas for volumes of various solids using the Ti-89 calculator. The lesson focuses on the keying sequences necessary to embed the required volume formula in a program which is then used in the problem solving...

Students explore the concept of environmental stewardship. In this science instructional activity, students investigate the effects of oil spills and brainstorm ideas to help companies avoid them as they create models to demonstrate...

Third graders engage in a lesson that focuses on the attributes and forming of a cube. They construct a cube using different combinations while comparing a square with only two-dimensions. Students fold paper while following the...

Learners conduct various experiments to investigate plant transpiration. In this biology lesson, students explain how this process helps maintain the hydrologic cycle. They measure the rate of water loss in plants using a potometer.

Students find the volume of spheres. In this geometry lesson, students measure and derive the formula for each shape and solid. They use the correct terminology and units when solving these problems.

Tenth graders discuss sides of a shape and how to collect data correctly. For this geometry lesson, 10th graders examine shapes and count the surfaces on the shape. They read the history of Mobius Band and relate it to surface area.

Students explore the concept of perimeter. For this perimeter lesson, students discuss how to find perimeter of various shapes. Students use the Perimeter Explorer applet to find the perimeter of various shapes.

Students construct a weather vane using their knowledge of some geometric shapes. In this weather lesson plan, students work in pairs to create a weather vane in order to measure wind direction. Students follow precise...

Learners learn the importance of washing their hands through a "hands on" germ activity. In this germ lesson plan, student put glow germ on their hands, and shake the teacher's hand. When put under a black light, students see the germs...

Students explore many of the unusual geographical features of the Amazon River region, and explain the importance of preserving the tropical rainforest.

Your task today: count all the trees on a tree farm. To complete the assignment, learners first estimate the number of trees on a tree farm using random sampling. To improve their own response they then evaluate provided...

Don't stuff money under your mattress. To find out why learners first complete a task determining how $24,000 in cash would affect the height of a mattress and whether this same amount would fit into a suitcase of given dimensions....
