Curated OER
Homogenous and Heterogeneous Mixtures
Fourth graders explain and describe what a mixture is, distinguish between the two types of mixtures (which are heterogeneous vs.homogenous) and are able to create and appropriately label mixtures.

Color Dots 3
Students make simple observations, test mixtures, and make generalized inferences from their observations. They observe bleeding of colored inks with water.
Curated OER
Mixtures
Students are introduced to the concept of mixtures. They identify materials used to make mixtures and describe what happens to the individual materials when they are mixed. In groups, they make bubbles by mixing water and soap together...
Curated OER
Matter And Its Changes
Fifth graders explore the phases of matter, make observations of matter, the physical and chemical properties of matter, solutions and mixtures, formation of molecules and atoms and molecules all through hands on activities.
