Explore the concept of density within states of matter—gases, liquids, and solids—through a group experiment in which young scientists test objects' texture, color, weight, size, and ability to sink or float.    

Engage young scientists in the upper-elementary and middle school grades with this collection of simple experiments. Whether you're teaching about heat transfer, density, or potential energy this resource has a lab for you.

Snow, ice, and water are all composed of H2O. Does that mean they all have the same volume? Discover the ways that the densities of these substances determine their volumes, and how they change based on their current states of...

Note that this lesson is best paired with the preceding lesson in the unit. In that lesson, elementary physical scientists observed that the color coating of M&Ms® candies do not mix when dissolved off of the chocolate surface. Now...

Not all liquids are the same. Investigate the viscosity of different fluids with a series of activities designed for eighth grade science. As learners move through learning centers with different experiment setups, they determine...

Atoms, elements, and molecules, oh my! Teaching the fundamentals of chemistry to curious sixth graders has never been easier to accomplish. Here is a resource that pulls together everything needed to get them off to a good start,...
