Arsenic and Selenium Removal From Drinking Water at a Minimal Cost
Decide on the most efficient plan to supply drinking water. The second project-based learning task in a two-part series builds upon the first project. Pupils revisit the wells to supply drinking water, but they must make sure the...

How Can Work Be Done with Water Power? Activity B
In this second of three activities, energy engineers plan and create a hydropower dam as they learn how hydroelectric power plants generate electricity. A hydropower puzzle is also included, which can be worked on by teams that finish...

Red Cabbage Chemistry
Using the natural pH indicator of red cabbage juice, groups determine the pH of different everyday liquids. As they work, pupils gain an understanding of pH that may help deal with contaminants in the water supply.

Grow Your Own Algae!
Develop a model of a wastewater treatment center. The last activity of the unit has pupils mix a lake water sample into a tank of water containing fertilizers. Over time, the algae from the lake water grows and removes the nutrient-rich...

Observing the Weather
How can you predict the weather without any technology? Young scientists learn to forecast the weather using traditional Native American techniques. Based on their observations of the weather, as well as talking to their classmates, they...

Create an Animal
Think beyond the animals and habitats we've already discovered and allow scholars to dream up their very own habitat and an animal that lives there. Class members present the new habitat and animal on a poster alongside an...

Messin' with Mixtures
Do you separate your trail mix before eating it? Then you've been separating mixtures your whole life! Scholars model a contaminated soil sample using trail mix and estimate the percentage of each component. They consider how to clean up...

Teach Engineering: Tippy Tap Plus Piping
The Tippy Tap hand-washing station is an inexpensive and effective device used extensively in the developing world. One shortcoming of the homemade device is that it must be manually refilled with water and therefore is of limited use in...

Science Buddies: Harmful Algal Blooms in the Chesapeake Bay
Harmful algal blooms occur when algae, which form the base of the ocean food web, grow in massive numbers and produce toxic or harmful effects on people, fish, shellfish, marine mammals, and birds. In this project you will learn how to...

Teach Engineering: Red Cabbage Chemistry
Students take advantage of the natural ability of red cabbage juice to perform as a pH indicator to test the pH of seven common household liquids. Then they evaluate the accuracy of the red cabbage indicator, by testing the pH of the...
