Chemical Reactions With Vinegar
Second graders observe chemical reactions. In this scientific inquiry lesson plan, 2nd graders determine whether vinegar creates a chemical reaction by observing two different experiments. A list of 7 supplies is included. In addition,...
Curated OER
Immiscible Liquids and Density
Students will make a lava lamp. For this density lesson, students will combine water and oil and make observations, then add salt to the oil and observe the oil sink, then float again when the salt dissolves in the water.

Pipeline to the Coral Reefs
High schoolers discuss the relationship of density to stratification. In this marine science lesson, students create a model of upwelling events using cold and warm water. They discuss how water phenomena affect coral reefs.
Curated OER
Frozen Film
Students are introduced to the topic of light interference through this hands-on activity. They observe how light reflects off two surfaces and then meets to form an interesting variation of color on a film surface.
