How do scientists determine the best method for removing pollutants from our water sources? Environmental scholars experiment with pollution clean-up options to discover which are the most cost-effective, fastest, and most thorough....

Drinking clean water can be taken for granted. Explore the process and high cost of filtering water with a water pollution and filtration activity. Young scientist build a filtration system to filter polluted water, examine the economics...

This science assignment produced by NASA teaches inquiring minds the distribution of Earth's water. Learners will appreciate and understand the importance of fresh water and how weather and climate affects everything.

It may be tricky for a young mind to conceptualize that less than 1% of all water on earth is useable for humans to drink. Simulating the amount of fresh water available on earth by removing measured amounts of water from a five-gallon...

With almost half of Americans relying on groundwater supplies, it is more important than ever to protect aquifers from possible contaminants. Working in small groups, young environmentalists explore this problem as they create an aquifer...

How are maps like fish? They both have scales. The chapter includes six different activities at three different levels. Scholars complete activities using natural resources, learn how to read a map, see how to make a compass rosette,...

Equip young campers with the tips and strategies for a safe trip to the outdoors with a series of lessons. They learn how to start fires with and without firewood, keep warm in snowy weather, and purify water to make it safe for drinking.

What is more important: building a new school or preserving a nature reserve? Keeping a natural area clean or providing clean drinking water to a city of millions? Young scholars weigh these questions—almost literally—using an...

Groups use alcohol and chromatography paper to separate the color components of black ink. The purpose of the activity is to allow the class to become aware that mixtures exist in hidden places. 

The earth is a delicate and fragile thing; Why not engage your class in a craft project that will make them aware of our environment? Earth Day is celebrated as recycled materials are used to create earth window hangings. Crayons are...

It's cloudy with a good chance of learning! An inquiry-based lesson begins with an exploration of transparent, translucent, and opaque materials. Young scientists then connect their learning to the different cloud types as they take the...

Sometimes the simplest experiments leave the biggest impression! Introduce young chemists to the Cartesian Diver by having them make one of their own. Use the Diver to further their study of liquids and gases, as well as compression.

Educate your class about blood alcohol levels by combining health with math practice. Class members read a little bit about blood alcohol concentration and then solve some problems related to determining alcohol levels and alcohol...
