Dissolving
What happens to substances when they dissolve in water? Young scientists investigate the dissolving process with a colorful interactive. The resource illustrates changes in potential energy as solute particles interact with water...
Cornell University
Polymers: Instant Snow
Is it easy to make snow? Scholars use critical thinking skills as they investigate the concept of polymers by making snow. The class tests several different variables and takes measurements over the course of several days. They then...

Practice Exam Bonding and Acid-Base
In this chemistry worksheet, young scholars respond to several multiple choice questions relating to bonding and acid-bases. They also identify the various types of bases and how they differ from each other.
Santa Monica College
Lewis Structures and Molecular Shapes
Learners practice drawing Lewis dot structures, build molecules with model kits, and predict molecular shapes using VSEPR theory. The combination of written work and hands-on reinforcement benefits young scientists.

Gumdrop Atoms
There's nothing sticky about the resource, unless you count the gumdrops! Scholars create a model of a lithium atom, complete with protons, neutrons, and electrons. It's just that these models are made with gumdrops and toothpicks.
