Students investigate the amount of rainfall in Manu, Peru. They view and discuss a video and fill a rain guage with the amount of rainfall in Manu. They research and compare local rainfall amounts to those of Manu, and write about what...

Students investigate how friction affects the movement of a block across surface areas. They test five different kinds of surfaces—smooth surface, wax paper, a paper towel, course, and fine sandpaper. They predict and record the results...

In this geometry worksheet, 10th graders solve problems by finding the perimeter, area and volume of polygons. There are 17 questions with an answer key.

Students model the effects of wind speed and water depth on the height of waves during a hurricane. In this meteorology lesson plan, students use a flexible straw and a 9X 13 baking dish to measure the differences in wave...

Fourth graders study the Civil War and discuss what soldiers ate during that time period. In groups, representing Union and Confederate soldiers, they follow recipes, prepare, eat, and share Union hardtack and Confederate Johnnie Cakes.

Students identify how to use a scatterplot to compare two sets of data to determine if they are related. Then they identify and describe the definition of regression line (the "line of best fit"). Students also identify how scientists...

Students to the book, Life in a Pond, then discuss the food chain and create a food chain mobile. On one strip of paper students draw and label a pond plant, on another a tadpole, on another a fish and on the last a person.

In this angular size and similar triangles learning exercise, students use the properties of similar triangles and the ratios of sides to solve for unknowns in given diagrams.

In this geometry worksheet, 10th graders answer questions about right triangles by identifying the 3 sides of the triangle. They analyze the different shapes of polygons and relate them to right triangles to find the sides using the...

In this word problem worksheet, students complete ten multiple choice word problems by choosing the correct mathematical operation. This is an interactive worksheet.

Students experiment with yeast. In this environmental conditions lesson plan students test the viability of samples of yeast. Students investigate the effects of environmental conditions on the yeast.

In this area worksheet, students find the area of four rectangles when given the drawings with grid markings inside each. They use the area formula to find the area of five rectangles. This worksheet is intended to be used as a part of a...

Eighth graders explore the scarcity of energy resources. They also explore the competition for natural resources and the inadequate distribution of natural wealth among the Earth's nations.

Second graders utilize manipulatives (pentominoes) to demonstrate knowledge of: lines of symmetry, slides, reflections (flips), rotations (turns), area, and perimeter. This lesson gives students a meaningful way to practice these...
