Curated OER
The Chemical Nature of Water
Seventh graders simulate a Jeopardy game to examine the chemical nature of water. Among the topics featured are evaporation, water, salt, and temperature. finally, as review, 7th graders answer a battery of questions presented by the...

Air Pollution Over Where?
Students predict the movement of an air borne pollutant using their understanding of air currents. They determine which governments and/or communities should be contacted to be forewarned. They also explore the properties of their...

Middle School Chemistry: Air: It's Really There
Investigation shows that gas takes up space and has mass, and that the motion of gas molecules is affected by heating and cooling.
Vision Learning
Vision Learning: States of Matter
Did you know the ancient Greeks first identified the three states of matter? Read about how the molecules differ in solids, liquids, gases, and plasma. View photographs and watch how the molecules move in each state. If you're really...

Atoms in Motion: All Matter Is Made of Atoms
Atoms are very, very small. Atoms are so small that it is often said that there are as many atoms in a single grain of sand as there are grains of sand on all of the world's beaches - certainly a difficult thing to prove, but you get the...

Serc: Mn Step: States of Matter: Which Will Propel the Balloon?
For this activity, learners take part in a simulation of the three states of matter where they role play being molecules. They then create simple balloon rockets and must explain why a gas is the only state of matter that can cause the...

New York University: States of Water
Use this resource to learn about the three different phases of water; solid, liquid, and gas. What happens to water as it changes into a solid or gas? Includes short and easy to do activity.
Purdue University
Purdue Univ: Gases, Liquids, and Solids
This site has a brief description of the differences in particles in a gas, liquid, and solid. Animated microscopic pictures demonstrate the molecular movement in each state. Information is then summarized in an easy-to-read chart.
