Tiny particles can provide big learning opportunities! Middle school scientists explore the world of nanoparticles through reading, discussion, and experiment. Collaborative groups first apply nanotechnology to determine water...

Here is a different approach to solutions: a instructional activity that has chemistry learners use words to describe them! This is an outstanding exercise that will stretch learners to show what they know. They answer questions...

Sixth graders experiment with mixtures. In this chemistry lesson, 6th graders determine which mixtures are considered heterogeneous, a suspension, a solution or a colloid. Students create a data sheet of what they discover.

In this classification of changes worksheet, students identify each example as either chemical or physical changes. Students also classify other examples as either element, compound, solution, colloid, or suspensions. In the other...

Students listen to the book, "Oobleck," by Dr. Suess before experimenting with mystery powders. They determine the proper ratio of powder to liquid to make the Oobleck.

In this mixtures pre-lab worksheet, students compare and contrast suspensions and colloids and solutions and colloids. Students describe the Tyndall effect. This worksheet has 10 short answer questions.

A ten-question quiz on the chemical properties of mixtures.
