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...

Explore the sun's ability to distill contaminated water with this simple set of classroom experiments. After filling two glass bowls, one with muddy water and the other with salt water, they are covered with plastic wrap and placed...

Young surveyors look for patterns in water flow around campus. Using a map of the school (that you will need to create), they mark the direction of the path of water. They also perform calculations for the volume that becomes runoff. The...

Mass and density — aren't they the same thing? This activity has groups use balance beams and water displacement to measure several objects. The pupils use the measurements to calculate the density of the objects. 

Will it sink or will it float? Learners predict the outcome as they drop random objects into a container of water. Then, they keep track of the results and record the data in a t-chart to draw a final conclusion.

There has been a huge solar energy spill! Let's go outside to play in it. This lesson includes multiple experiments showcasing solar and wind energies. Scholars build a solar heater and an anemometer before testing the results. The...

What is water worth to you? The answer probably depends on many different variables. Learners explore the value of water in space and what it takes to transport the resource to locations in a galaxy far far away. They then consider...

Middle schoolers work as a team to help improve the quality of life in rural Africa and develop a plan how to spend grant money the United Nations has provided them with.

A well-developed lab sheet guides physical science learners through an investigation of kinetic and potential energy. In small groups, collaborators discover whether or not the ramp height or mass of an object has an effect on the...

By looking at the bottom dwelling macroinvertebrates, students will investigate water quality and habitat quality in this field lab. Students will record the number of creatures found at the bottom of a pond, lake, ditch, stream or river...

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...

Using a variety of science topics, these projects link your class with classes around the world in data collection and analysis. There are projects recommended for all grade levels. Begin dates and end dates are listed to help in...

Here is an interesting project that could be approached from several different scientific angles: Environmental Science, Weather & Atmosphere, Chemistry, or Plant Biology. You can probably think of your own variations to emphasize...

JASON Aquatic Field Study: Use water temperature, turbidity, and dissolved oxygen data collected by researchers to examine the quality of an aquatic site using a TI-73 Explorer to graph and analyze the values and determine its water...
