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

Use these free STEM lessons and activities to help students get hands-on building, testing, and exploring the science of the water cycle. With more than 70% of Earth's surface covered in water, water is one of the planet's most abundant natural resources. Thanks to the natural hydrologic cycle (water cycle), water on Earth is continuously recycled. In this process, water shifts between solid, liquid, and gaseous forms, occupying all three states of… Read more
