Science Buddies: Put Your Water to Work: Using Hydropower to Lift a Load

Incorporate reading strategies, math, research, and the scientific method into one lesson about water conservation. After reading a story about a landlady trying to determine how many people are living in an apartment, learners develop a...

Don't lift another finger, this physical and environmental science unit has everything you need to begin teaching your class about energy. Starting with a look at the greenhouse effect, these lessons and activities take young scientists...

Can a sidewalk increase the amount of pollution in local streams? Scholars learn the answer to this question though research and experimentation in the fifth unit in the six-part series. Pupils study runoff, impervious surfaces, and the...

Teams design and build a windmill, under budget, that can lift an object. The groups evaluate and reflect on their own design, then on those produced by other teams. The goal is to determine which design is the most...

Check out this science fair project to determine how much power your PC really uses, and if it is an energy hog, how you can reduce its appetite for energy. You will learn how to profile and streamline your computer's power usage, while...

Here is a six-minute video of a pair of electrical engineers that illustrate how to build a wind turbine. A list of materials is provided, along with general guidelines for your class. Use this to introduce turbine design to your...

Metals are a part of our lives in so many ways that we hardly notice them. Cars, bikes, and planes are all composed of metals. Some people even have metal in the dental work in their mouths. Therefore the strength and dependence of metal...

Physical science fans find out how supercooled water droplets in the clouds can become crystalline snowflakes. They learn about the categories of snowflakes (plates and columns) and the variables that determine their patterns...

How safe is the drinking water you have access to? Colors, smells, and other factors may lead you to finding out if your water is safe. Watch a video that explains the ways water becomes filtered and ways to know when water is contaminated.

Explore a day in the life of a water droplet. An interactive infographic helps scholars learn how water cycles work from precipitation all the way around to condensation. Learners hover over each step of the cycle to read more as they...
