Ted: Ted Ed: The Chemistry of Cold Packs
If you stick water in the freezer, it will take a few hours to freeze into ice. How is it, then, that cold packs go from room temperature to near freezing in mere seconds? John Pollard details the chemistry of the cold pack, shedding...

Science Buddies: Investigate Mpemba Effect Can Hot Water Freeze Faster Than Cold
This physics project seems like it should have an easy answer. Instead, it turns out to be a great illustration of why it is important to base scientific conclusions on the outcome of controlled experiments. Things don't always turn out...

Science Buddies: Keep Your Candy Cool With the Power of Evaporation!
Did you know that your body has a built-in cooler? And it might not be what you think. Sweat is produced when you are hot, but its purpose is actually to cool your body as the water in it evaporates from your skin. In this science fair...

Serc: Investigating the Water Cycle "Snow Fun"
In this teacher directed inquiry indoor lab students collect snow in a cup. They will estimate how much water will be in the cup after the snow melts. Students will then make predictions about what will happen to the cup of water. After...

Teach Engineering: Natural and Urban "Stormwater" Water Cycle Models
Students apply their understanding of the natural water cycle and the urban stormwater water cycle, as well as the processes involved in both cycles to hypothesize how the flow of water is affected by altering precipitation.

Teach Engineering: Where Has All the Water Gone?
Learners learn about the Earth's water cycle, especially about evaporation. Once a dam is constructed, its reservoir becomes a part of the region's natural hydrologic cycle by receiving precipitation, storing runoff water and evaporating...
