Curated OER
Demonstrating the Kinds of Energy
Students experiment with inner tubes, weights, flasks, and pistons to demonstrate the gas laws. In this molecular motion instructional activity, students demonstrate pressure as a force per area. They conduct an experiment to show the...
Curated OER
Temperature Changes Everything
Middle school chemists visit interactive websites in order to discover what happens to molecular motion when heat is added to matter. They conduct an experiment that demonstrates the expansion of matter with the addition of heat. A lab...
Curated OER
Weather Lesson 1
Students describe and compare the layers of the atmosphere. They explain how to measure the temperature of the atmosphere. They also explain what causes the atmosphere to heat up in some places more than in others.
Curated OER
Heat Transfer & Phase Changes
In this heat transfer and phase change worksheet, learners experiment with ice, salt, and milk to show the relationship between the temperature of a solution and its phase. Students turn milk from a liquid to a solid and graph the...

Water – Changing States (Part 2)
Here is part two of a two-part lesson in which scholars investigate the changing states of water—liquid, solid, and gas—and how energy from heat changes its molecules. With grand conversation, two demonstrations, and one hands-on...

Water—Changing States (Part 1)
Here is part one of a two-part lesson in which scholars investigate the changing states of water—liquid, solid, and gas. With grand conversation and up to three demonstrations, learners make predictions about what they think will happen...
Curated OER
Hot Air Balloons
Middle schoolers examine how a hot air balloon works. In this hot air balloon lesson, students do an experiment to test the effects of heat on density. Middle schoolers make their own hot air balloon and act out how nitrogen moves when...

Air, It's Really There
Love is in the air? Wrong — nitrogen, oxygen, and carbon dioxide are in the air. The final lesson in the series of five covers the impact of temperature on gases. Scholars view a demonstration of gas as a type of matter before performing...
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.
Curated OER
What is Air?
Young scholars investigate air by participating in a class experiment. In this matter measurement lesson plan, students identify air as a gas which consists of mass. Young scholars utilize a windsock or balloon to measure oxygen and...
Curated OER
"Heat Transfer and Ice Cream!"
Students analyze earth science by creating a frozen treat in class. In this heat transfer lesson, students discuss how matter is transformed from solid to liquid and liquid to gas when energy is removed from the equation. Students...
Curated OER
Traveling Sound
Learners explore how sound waves move through liquids, solids and gases in a series of simple sound energy experiments. They describe how sound needs molecules to move and that changing the medium that it travels through changes the...
Curated OER
The Nature of Chemical Change: Acting Out an Example
Students identify the signs that a chemical reaction took place. In this chemistry lesson, students role play the movement of different molecules of matter. They classify matter according to their properties.
American Chemical Society
Forming a Precipitate
Can you mix two liquids to make a solid that is insoluble? Yes, you can, and pupils see this as the lesson uses more than one combination of liquids to form a solid. Through two teacher demonstrations and a hands-on activity, scholars...
Curated OER
Phases of Matter
In this matter worksheet, students calculate volume and partial pressure for gases, compare liquid and vapor phases, and review the characteristics properties of gases. This worksheet has 12 multiple choice and 3 problems to solve.
Curated OER
IB Chemistry Practice Test
In this chemistry review worksheet, students practice using Avogadro's number, calculating number of moles, and using the gas laws. This worksheet has 39 multiple choice questions.
Curated OER
Temperature Changes Everything
Pupils determine the effect of temperature on the motion of particles. They study the difference between particles in a gas, liquid, and a solid and see how the characteristics of solids, liquids, and gases can be explained by particle...

Density and Pressure of a Hot Air Balloon
Using a dry cleaner bag and a blow dryer, create a hot air balloon! The materials list suggests obtaining one dry cleaner bag per student, but since this is probably inconvenient, consider doing this as a demonstration during a lesson on...
Curated OER
Chromosomes
Students study chromosomes and how molecular half life affects them. For this chromosome lesson students complete several lab activities on calculating half life, and cracking alkanes.
Curated OER
Density: Floating, Sinking, and Suspending
Students observe teacher demonstrations that illustrate density. In this density lesson, the teacher demonstrates how air bubbles in a carbonated drink can cause a raisin to float and how an egg sinks in fresh water, but floats in salt...
Curated OER
Structure-Property Relationships
Students explore the structure and property changes of water through videos and classroom discussion. They are introduced to atomic arrangement of solids by looking closely at carbon in different forms, such as graphite and diamond....
Curated OER
Three Clouds Activity
Students explore how clouds are produced through three different age-appropriate hands-on experiments.
Curated OER
Clean Air
Students observe gas molecules in the atmosphere absorbing the light that goes through them.
