Making Mayonnaise - An Edible Emulsion

Curious physical scientists follow a lesson on the properties of water with this lesson on distillation. They observe a miniature water cycle model that filters dirty water into clean water. These two lessons combined are an enriching...

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....

Investigate the different types of pollution that storm drain runoff carries into oceans, lakes, rivers, and streams with this class demonstration. Using an aquarium and an assortment of everyday items that contaminants like motor oil,...

Students construct a water filter. In this engineering lesson, students discover how to construct a water filtration system. Students work in groups to sort tools by their properties. Students analyze and construct a water filtration...

Sixth graders investigate the various types of pollutants found in water and ways to help prevent water pollution. Through a hands-on experiment, students create samples of polluted water by mixing water with vegetable oil, dirt,...

Spangler has a fourth grader join him in this segment. Her science fair project was a demonstration of how biologists cleaned up the birds and other wildlife that were affected by an oil spill. Amazingly, it's as simple as using soap!...

Now it becomes crystal clear why the unit is called Mixtures and Solutions. The fifth installment of a six-part unit explores mixtures and solutions. After viewing a demonstration on mixing pebbles with water, salt with water, and...

Mixtures and solutions are different; one can be separated fairly easily and the other cannot. This hands-on experiment was written specifically for learners with visual impairments or blindness. They will use lemonade and trail mix to...

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...

Students will create art by mixing watercolors with vegetable oil. By mixing the liquids, students can experiment the different properties of liquids. Lesson is developed to be a culminating project for a unit on liquids.
