Young scholars examine how Earth-Sun relationships affect Earth's energy balance and the pattern of world temperatures. Students study a Surface Temperature Regions map and write a paragraph describing the temperature pattern from the...

Students conduct a series of hands-on experiments that help them explain the role of lift in fixed-wing flight. They observe the flow of air and water around several surfaces and then consider the dynamics of airflow around an aircraft...

Young scholars investigate the motion of water currents by mapping the possible movement of messages cast into the ocean in bottles.They accurately plot the appearance of bottles on a world map and illustrate the flow of an ocean...

First graders discuss why some things sink and some float after dropping a variety of items into water.

Students explain and understand the circulation of air in the atmosphere. They identify that energy can be carried from one place to another by heat flow or by waves, including water, light and sound waves, or by moving objects. ...

Students study the properties of ocean water and tides and learn about animals that live in intertidal zones. In this intertidal zone lesson, students participate in classroom stations to learn about fresh water and salt water, cold...

Students investigate the concept of an aquifer and use a 2 liter bottle and other materials to conduct a simple lab experiment or demonstration. They calculate the volume of water that can be stored in the aquifer. The lab is used to...

Learners observe evaporation in a controlled environment. Evaporation is the change of liquid water into water vapor (a gas). The rate of evaporation is determined by many factors such as air temperature and humidity, liquid temperature...

Middle schoolers discuss why the ocean is salty. They discuss what salinity is. Students are told that is they want to know how much salt is in a body or water, they would use a special scientific tool. They complete an Estuarine Layers...

Third graders watch a demonstration on how craters were formed on the moon. Individually, they care given a set of materials that represent the moon surface and make their own craters. To end the lesson, they measure the size of the...

Middle schoolers investigate various properties of ice including melting points and the effect of pressure on ice. They demonstrate how increased pressure lowers the melting point of ice and perform a simple experiment proving that water...

Students list as a class the sources of arsenic contamination of water. They describe the major health effects of arsenic contamination in a letter. Students identify the regions that are affected by it.

Students observe the currents that occur through convection in water and relate them to the currents in molten rock in the Earth's mantle. They set up a convection current in a cake pan of water using a bag of ice on one end and an...

Students, in groups, observe the effect of water and ice on surface features of the land. They alsoexplore erosion and deposition.

Young scholars discover that air takes up space by watching the teacher demonstrate a simple activity using a glass jar, styrofoam packing peanut, and a clear bowl of water.

Students identify the processes involved in the water cycle. In this math lesson, students explain what civil engineers and hydrologist do. They watch a video about flooding in Texas.
