Why Do Raindrops Sometimes Land Gently and Sometimes with a Splat?
A mouse can fall from large heights without injury! Air resistance is a large influence on small falling objects. In an exploratory lesson, young scholars build a raindrop bottle to compare the falling rate of different-sized objects.

Properties of Matter
Never trust an atom; they make up everything! Young chemists make modeling dough and add another ingredient to change the properties. Scholars then compare the properties of emulsion to composite materials. A reading passage and analysis...

Color Splash
Young scholars investigate density. In this density instructional activity, students conduct an experiment using food coloring. Young scholars observe the differences in mixing food coloring in water and oil.
Curated OER
Science: Different Levels of Density
Students observe experiments in density and describe the results. In the experiment, milk, corn syrup, and oil are added in different orders to three glasses, while one other glass contains only water. As objects are dropped into each...
Curated OER
Storm Drain Dumping
Young scholars conduct an experiment to show how water gets contaminated through neighborhood runoffs.
Curated OER
As a Matter of Fact
Students rotate through various hands-on experiment stations to explore the concept and properties of different types of matter. They compare some properties of solids, liquids and gases and describe how matter changes from one state to...

Build a Better Bouncer
Students experiment with silly putty. In this chemical changes lesson students work in groups, perform tests and collect data.
Curated OER
Storm Drain Dumping
Students develop an awareness of what happens to water contaminated through neighborhood runoffs. Students perform an experiment that shows what happens to runoff when it's diverted to different places.

Hydrogen Powered Cars
Learners apply the principles of chemistry to investigate the concept of how a hydrogen powered car works. They study the electrochemical reactions that provide the energy source. Students also record observations in the functioning of a...
Curated OER
Atomic Theory, Structure, and Symbols
In this atomic theory activity, students review the observations that led to the conclusion of the atom having a positively charged nucleus. Students compare atomic number and mass number and explain how the discovery of subatomic...

Density In A Wave Machine
Young scholars explore density. In this science lesson plan, students gain an understanding of the concept of density, especially as it relates to liquid. Young scholars demonstrate that a less dense liquid will float on a denser liquid...

Chemistry in the Kitchen
Students, in groups, combine given materials from an everyday kitchen until a chemical reaction occurs and record the reaction time.
Curated OER
It's a Gas - Natural Gas
Learners use plastic bottles, water, and condiment packets to simulate how natural gas comes from decaying ocean plants and animals. In this natural gas lesson plan, students also fill out lab packets and answer exit questions.
Curated OER
The Three States of Matter
Third graders identify properties of solids, liquids, and gasses. In this states of matter lesson, the teacher demonstrates the properties of each state of matter, then students go on a scavenger hunt for items to represent each state...
