Devising a Set of Experiments to Test Water for Dissolved Substances

The Gulf of Mexico dead zone, an area of low oxygen that kills marine life, costs the United States $82 million every year. Young scientists research anoxic ocean environments then come up with a hypothesis for the cause of the Gulf of...

Get three planes to line up safely. Individuals work through a set of problems to eliminate spacing conflicts between three airplanes in flight. The pupils use their knowledge to change the airplanes' speed or route to meet a...

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...

Why did the orchestra director use a copper baton? She heard it makes a great conductor. Scholars select six items to test in a circuit to determine if each is a conductor or an insulator. Clear instructions for using electricity allow...

How can everyone in the world have access to clean drinking water? Throughout the lesson plan, learners read about and listen to how water is filtered, what the filtration process removes, and  the best ways to filter. They explore the...

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

Investigate experimental design through a hands-on exploration. A creative lesson allows learners to design an experiment to monitor the effects of alcohol on the C. elegans worm. After conducting the experiment, individuals analyze...

Protect skin from UV radiation! Groups design and conduct an experiment to test the effectiveness of UV safety products. The groups collect the data from the experiment and prepare a lab report. In the second day of the activity,...

Water is common? Not really! Learn how the polarity of the water molecule gives it tremendous properties that make is quite unique in the universe. Learners will understand surface tension, adhesion, and cohesion, as well as why these...

Water filtration — that's pure genius! Groups test the ability of a water filter to purify water by running chlorine contaminated water through a filter and measuring the chlorine concentrations as they filter the water. They then graph...
