From gas to liquid condensation to solid frost, water undergoes phase changes before young scholars' eyes! Using ice, salt, water, and a metal can, they set up an investigation that can be used in a physical science setting, or as part...

Clever! Use a clip from the 1997 film, Volcano, to get your chemistry class knee-deep in heat concepts related to lava. In the movie scene, lava flow is stopped in the nick of time. Your class must use calculations to determine if this...

This is one in several lessons that explore the relationship between temperature and phase changes of water. After some discussion, elementary physical scientists place wet paper toweling on a hot and a room-temperature water bag...

Young scientists transform themselves into rivers, oceans, clouds, and drops of water in order to explore the water cycle. After assigning and explaining to students their different roles in the activity, the teacher reads aloud a...

It's time to break the ice! If you are doing all of the lessons in the unit, children have already seen that increasing heat increases the rate of evaporation, but is the opposite true? Does decreasing temperature cause more condensation...

As a stand-alone or as part of the intended unit, this is a valid investigation of what causes condensation to occur.  By limiting the amount of air around a cold cup of water and comparing it to one out in the open, they find that...

I scream, you scream, we all scream for ice cream! Even high schoolers enjoy making ice cream. This laboratory exercise has them record the temperature changes throughout the process of liquid becoming solid, graph the results, and...

Is there more to evaporation than just less liquid? Show young scientists the energy transformation that occurs during a phase change through a series of simple experiments. Lab partners place drops of water, ethanol, and ethoxyethane on...

Plasma is the most common phase of matter in our universe. Scholars explore the change of energy as molecules change phases of matter. They rotate through stations, graphing the changes in energy level.

If the area you live in is arid, or the preceding experiment in this unit didn't yield obvious results, use this one in place of it to help reveal where condensation comes from. The mini unit that this is part of a comprehensive...

How much does your class know about the relationship between climate change and carbon dioxide? Science scholars explore the nature of greenhouse gases and rising ocean temperature through demonstrations, research, and experiments. The...

Third graders examine the phase change between solids and liquids and determine it to be a physical change. Ice is the perfect item to use to demonstrate this phase change. Pupils experiment with measuring and weighing solid ice and the...

Students study the changes in land formations caused by water erosion. They work in groups to build a model of a mountain composed of materials that will best withstand water erosion.

Cost overruns are unacceptable—in the real world and in an engaging activity. Groups of pupils get together to build a bridge out of straws, paper cups, and tape. They keep track of costs ($1,000 for each material) and must stay within a...

There's more to fluids than meet the eye—they include gases, liquids, and polymers, too! Scholars complete three hands-on activities exploring different properties of fluids. They explore viscosity by measuring the resistance, or...
