Scale Models
With instructions to adapt the activities for any grade K-12, any teacher can incorporate the concept of scale into the classroom with a simple, yet effective lesson.
University of Colorado
Clay Planets
Why do scientists use models? In the first installment of 22, groups create scale models of our solar system. They then share and discuss their models.

Activity 1 Up, Up, and Away: Building a Hot Air Balloon
Learners investigate the question: "How does a hot air balloon work?" They build small hot air balloons ans then lauch them. Students discuss how they think a hot air balloon floats. Pupils are introduced to the use of models as a...
Cornell University
Atomic Bonding
Explore the connection of surface area to bonding within atoms. Learners complete lab investigations to model changing surface area with different sizes and concentrations of atoms. A flour fireball demonstration follows the labs to...

The Particle Theory of Matter
Demonstrate the particle theory of matter to high school scientists with an engaging experiment that allows them to visually see the results as substances change from one state to another. The class concludes with a discussion about how...
Curated OER
Matter
Fifth graders investigate the structure of matter. They examine pictures of atoms and molecules and discuss their relationships, and construct a model of a molecule using toothpicks and gumdrops.

Active and Passive Transport: Red Rover Send Particles Over
I can move about freely, but you cannot. The class models the movement through cell membranes by way of passive and active transport. Members of the class play the roles of various proteins, atoms, compounds, and cell actions and mimic...
Curated OER
Virus and Bacteriophage
Students examine the differences between a virus and a bacteriophage. They explore various websites, identify the parts of a virus and a bacteriophage, and construct a model of a virus or bacteriophage.
