Use these free science lessons, experiments, and activities to teach K-12 students about density. Sometimes students wrongly think that an object's density is the same as its weight or its mass. Instead, density refers to an object's mass in a given volume. Two objects that have the same shape and size (volume) but have a different mass (like two same-sized balls with different weights) have different densities. As a physical property of… Read more

Use these free STEM lessons and activities to help students get hands-on experimenting with the science and chemistry of mixtures and solutions. Most students have a basic concept of "mixtures." They have combined ingredients in the kitchen. They know that beverages, paints, and glues are mixtures. They may realize that blood is a mixture, as is the air we breathe. They know that some things "mix" well and others don't and that some mixtures are… Read more
