Filtration Investigation
Scholars build a simple filtration system to remove impurities from muddy water and rate the filtered water to a grade of clarity scale. The focus is on teamwork and problem solving. This instructional activity would be effective in your...
SRI International
Nanofiltration
How can everyone in the world have access to clean drinking water? Throughout the instructional activity, learners read about and listen to how water is filtered, what the filtration process removes, and the best ways to filter....

Boiling and Freezing Points of Water
Challenge your sixth graders with this lesson about the freezing and boiling points of water. In these activities learners graph temperature data, read and analyze information, and identify the freezing and boiling points of water and...
Exploratorium
Water Sphere Lens
With a Florence flask or fishbowl, make a double convex lens and use it to examine an image. Because of the refraction, the image will be inverted. A simple explanation is provided here for you to share with your class as they...

Grade 4 Elementary Level Science Test (2004)
In this science assessment worksheet, students complete a 41 question multiple choice and short essay science test on all grade 4 skills.
Concord Consortium
Molecular Sorting
Can scientists sort molecules based on their interaction with oil and water? The simulation demonstrates how this is possible. Pupils decide when to insert a molecule and observe how they sort themselves based on polarity.
Concord Consortium
Mixing Liquids
Sometimes being mixed up is a good thing! Young chemists explore the basics of making solutions with a realistic interactive. Pupils observe the differences in volume using quantities of water and ethanol, as well as the effects of...
