Search Results

In this outdoor activity, learners search for the warmest and coolest, windiest and calmest, wettest and driest, and brightest and darkest spots in an area.

In this outdoor activity, learners use only their senses to to find the extremes of several environmental variables or physical factors: wind, temperature, light, slope and moisture.

In this weather forecasting activity, learners determine the location of cold and warm fronts on weather plot maps.

In this activity, learners create their own weather forecast map.

In this activity, learners create their own icons for a forecast-at-a-glance poster for their classroom/learning space.

In this activity, learners discover that sand is the major ingredient in glass.

In this activity, learners use a toaster to generate wind and compare the appliance's heat source to Jupiter's own hot interior. Learners discover that convection drives wind on Jupiter and on Earth.

In this activity, learners examine the parts of a thermometer. After placing a thermometer in hot and cold water, learners look at molecular model animations of the liquid in a thermometer.

Learners investigate how the temperature of water affects its density.

In this experiment, learners use a blow dryer and water bottle to observe and record changes in air pressure caused by changes in temperature.

Why is ocean water sometimes the warmest when the average daily air temperature starts to drop? In this activity, learners explore the differing heat capacities of water and air using real data.

In this activity, learners simulate the behavior of the atmosphere.

In this outdoor, winter activity, learners find living green plants under the snow and determine the light and temperature conditions around the plants.

In this activity, learners will examine various world data maps to combine the information and predict which areas could be tropical rainforests.

Learners add calcium chloride to a baking soda solution and observe an increase in temperature along with the production of a gas and a white precipitate. These are all signs of a chemical reaction.

In this activity, learners explore how engineers have met the challenge of keeping foods, liquids, and other items cool.
