This is a hands-on lab activity about the properties and states of water. Learners will complete activities using different liquids to understand the three states of matter, explain how the high heat capacity and abundance of liquid water makes life... (View More)

In this activity, student teams design small-scale physical models of hot and cold planets, (Venus and Mars), and learn that small scale models allow researchers to determine how much larger systems function. There is both a team challenge and... (View More)

In this laboratory activity, students are introduced to the different particle sizes of soil and their properties. Using sieves, students remove organic materials and pebbles, and separate sand, silt, and clay. Students experiment by combining sand,... (View More)

This activity introduces the primary colors of light. Satellites transmit images to us as a series of numbers, and this activity is designed to show how numbers are combined to create images using the primary colors of light. Students work in groups... (View More)

This exercise shows a practical application of trigonometry in the aviation environment, where student pilots consider the relationship between altitude and distance to complete a landing. It requires a scientific calculator. This resource is from... (View More)

A caller on an automotive-themed radio program asked for help with a problem. It seems that when it rained her windshield wipers sometimes turned themselves on. How is this possible? This resource provides an explanation by exploring electrical... (View More)

Students will collect samples of particles in the air on simple slides they make themselves. They will classify, count and chart their findings, draw conclusions, make predictions, and compare their findings to other available data. Supplies needed... (View More)
