In this textbook chapter, students review concepts of matter and energy as a precursor to understand how carbon dioxide traps heat in the atmosphere. This is the second chapter in the unit, Climate Change, which addresses the question of how human... (View More)

In this investigation, students use "point-source" light, light meters, and graphing software to quantify the reduction in light over distance. Through careful measurement of light received at several distances, students discover the best fit of the... (View More)

Audience: High school
Materials Cost: Over $20 per group of students

In this lesson, students will explore the density of substances as a model for understanding the mass to light ratio as a predictor of dark matter. They will measure and calculate mass and volume to calculate the density of a foam ball. Students... (View More)

In this lesson, students explore a discrepant event when they design an experiment to measure the rate that ice melts when in pure water versus salt water. It is designed to help students realize that a carefully-designed experiment may yield... (View More)

Students use a calorimeter made of common materials to demonstrate that energy can be measured and converted from one form to another. Hydrocarbons, such as paraffin, contain stored chemical energy; food contains stored chemical energy. The activity... (View More)

In this activity, students will use a simulator of an orbiting X-ray observatory to observe a supernova remnant, the expanding gas from an exploded star. They will take X-ray spectral data, analyze them, and answer questions based on that data. This... (View More)

This is a hands-on lab activity about the chemical composition and conductivity of water. Working in groups, learners will: conduct an experiment involving the process of electrolysis, prepare an experiment to better understand the process of ion... (View More)

Audience: High school
Materials Cost: $1 - $5 per group of students

This educational wallsheet illustrates Newton's First Law of Motion. In the related activity, students will discover the properties of inertia and motion, and see how they have very important real-life applications. The activity includes background... (View More)

This educational wallsheet illustrates Newton's Third Law of Motion. The accompanying activity is an experiment in which students create a balloon and straw rocket. Students must figure out how to shoot the balloon from the back of the classroom and... (View More)

This activity has two purposes: challenge the learner to develop a procedure for investigating a research question and to learn more about factors affecting the dynamics of air in motion. It demonstrates that warm air and cold air differ in weight... (View More)
