Build Your Own Parachute
Young scholars study the basics of parachuting. In this flight and aerodynamics lesson students make a simple parachute and investigate different variables that can cause potential problems.
Curated OER
Density and Buoyancy Experimental Design
Students must plan, design, and conduct an experiment that answers the scientific question: "Come up with a question that addresses the factors (variables) of the water and its effect on whether an object floats or sinks."

Ideal Gas Law
In this chemistry worksheet, students write two forms of the ideal gas law. Then they identify the size and units of the ideal gas law. Students also solve the equations for each ideal gas law.
Curated OER
Rules of the Roll
Students roll a ball down a plank and measure the distance it travels. Students graph the distances the ball travels as they change the height of the incline (increase slope).

Watch That Plant Grow
Middle schoolers examine the growth of marigolds in a greenhouse environment. They chart data in spreadsheets showing plant growth over time and under a number of conditions. They record measures of plant height and greenhouse temperature.
Curated OER
Using a Database in Science Experiments
Fifth graders plant and take care of a lima bean plant and make predictions on its growth. In this science lesson, 5th graders chart their records and make conclusions about their experiment.

The Scaling Principle for Area
As they investigate scaling figures and calculate the resulting areas, groups determine the area of similar figures. They continue to investigate the results when the vertical and horizontal scales are not equal.

What Is a Trigonometric Identity?
Protect yourself from identity theft! Establishing a strong understanding of the Pythagorean identity allows learners to prove that sine^2x + cos^2x = 1. They then use the identity to find sine or cosine ratios given the other.
