The Nature of Chemical Change: Acting Out An Example
Young scholars illustrate the molecular nature of matter and show that chemical change involves alteration of molecules.
Curated OER
Atomic Models
Students explain scientists' ideas about the structure of the atom over the last century. They develop a pictorial history of the changing ideas about the atom and write a caption describing the scientific thinking behind the model.

Let's Break the Particles
Build learning by breaking atoms! Young scientists study the way energy changes with a hands-on activity. As they roll steel marbles down a ramp, learners test the hypothesis that kinetic energy does not go away with friction...
Curated OER
Matter
Students recognize that some changes to matter are reversible and some are not. In this matter lesson, students experiment a physical and chemical change. Students record experiment results in their science journals. Students act...

Differentiate Elements, Compounds, and Mixtures
Learners examine the differences between elements, compounds and mixtures. Using diagrams, they compare and contrast atoms and molecules and describe various chemical reactions. They distinguish the differences between ionic and...
Curated OER
Matter
Fifth graders investigate the nature of matter and of the scientific processes associated with them in this series of lessons.
Curated OER
The Elements
Students watch video, The Elements, research information about elements using both the Internet and CD-ROM program, and create atoms out of gumdrops and licorice.
Curated OER
Kinetic Molecular Theory
Students analyze and evaluate evidence that matter is made of tiny particles. They observe a series of phenomena involving solids, liquids, and gases to make inferences about the spacing, interactions and relative kinetic energies of the...
