Learners test two jars of ice water, one covered and one open, for changes in temperature. After placing the jars in the sun, learners discover that the covered jar cools down more slowly.

Learners will understand the relationship between climate change and sea-level rise.

This activity models some of the ways natural processes, such as erosion and sediment pollution, affect Earth’s landscape.

Learners cover a bottle with a balloon. When they immerse the bottle in warm water, the balloon inflates. When they immerse the bottle in a bowl of ice, the balloon deflates.

In this activity, learners explore sensors and focus specifically on how to measure humidity using a sensor.

In this activity, learners discover if carbon dioxide has an effect on temperature.

In this activity (on page 8), learners model how marble statues and buildings are affected by acid rain.

In this field study, learners discover how to collect data in the field and how their efforts can help certain animals, specifically, amphibians.

In this activity on page 7 of the PDF, learners investigate the solubility of gas in water at different temperatures. This experiment will help learners determine if temperature affects solubility.

In this activity, learners explore rocketry and the principals of space flight.

In this math lesson (on Page 13), learners predict and simulate the likelihood of an event occurring.

In this data collection and analysis activity, learners evaluate fish physiology and ecology using vision research data from Dr.

In this activity, learners explore how the area of Arctic sea ice has changed over recent years. First, learners graph the area of Arctic sea ice over time from 1979 to 2007.

In this outdoor activity/field trip, learners investigate organisms that live along the ocean's rocky coast.
