Learners test two jars containing soil, 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 investigate the concept of humidity by using a dry and wet sponge as a model. They determine a model for 100% humidity, a sponge saturated with water.

Learners test two jars, one containing plain air and one containing carbon dioxide gas, to see their reactions to temperature changes.

This is an activity that models the operation of a seismograph, a tool used to measure the size of earthquakes.

In this activity, learners explore the different salinities of various sources of water by taste-testing.

In this online activity, learners adjust mountain snowfall and temperature to see how glaciers grow and shrink. They will use scientific tools to measure thickness, velocity and glacial budget.

In this activity, learners discover how to determine the distance to a lightning strike or nearby thunderstorm.

In this activity, learners will estimate the sizes of balls to learn how to estimate the size of hail. Learners will compare their estimates to the estimates of their peers and the real measurements.

In this activity, learners discover how the extent of various wind speeds changes in each of the four quadrants around a hurricane.

Learners build a simple aneroid barometer to learn about changes in barometric pressure and weather forecasting. They observe their barometer and record data over a period of days.

In this activity, learners experiment and observe how the color of materials that cover the Earth affects the amounts of sunlight our planet absorbs.

In this seismic simulation, learners play a "who-dunnit" game to explore earthquakes.

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

In this activity, learners make a barometer, an instrument to measure change in air pressure.

In this oceanography and data collection activity, learners cast real time sea state conditions using buoys from NOAA's National Data Buoy Center.

In this activity, learners use simple items to construct a device for indicating air pressure changes.

In this indoor and/or outdoor activity, learners make an anemometer (an instrument to measure wind speed) out of a protractor, a ping pong ball and a length of thread or fishing line.

In this activity, learners explore the engineering behind seismographs and how technology has improved accurate recording of earthquakes.

In this activity, learners discover that one way to cool an object in the presence of a heat source is to increase the distance from it or change the angle at which it is faced.
