The Same, But Different
Third graders examine the phase change between solids and liquids and determine it to be a physical change. Ice is the perfect item to use to demonstrate this phase change. Pupils experiment with measuring and weighing solid ice and the...

States of Matter Quiz
In this science quiz activity, students read and answer 5 short answer questions and 5 true and false questions involving different types of matter in science.
Curated OER
State of Matter - Atoms
Students examine and discuss how atoms change from solid to liquid to gas. They inflate a balloon by melting ice that converts to steam, and discuss the results.
Curated OER
Physical Changes to Matter
Pupils explore matter by conducting an in-class experiment. They experiment with water's various forms by melting and freezing water, identifying its new shape. These observations are recorded to supplement later discussion. They also...

Science: The States of Matter
Third graders conduct experiments in matter to create chemical changes resulting in gases. By mixing solids and liquids, they create a chemical reaction and capture the gas in balloons. After observing the balloons fill with carbon...

Solids, Liquids, & Gases
Solids, liquid, and gas, the three states of matter, are the subject of a cross-curricular reading comprehension exercise that asks kids to first read an article about these forms, and then to respond to a series of questions based on...
Curated OER
Particle Model of Solids, Liquids, and Gases
Display the arrangement of molecules in solids, liquids, and gases. Demonstrate how the addition of heat energy results in greater molecular motion and therefore a change of phase. Give examples of heat conductors and insulators, and...

South Pole Ice Cream!
How can you turn an ice cream activity into a scientific investigation? It's easy if you know ionic compounds, heat transfer, and the exothermic and endothermic process. Learners will explore the science behind freezing, insulation, and...
Curated OER
Changing States: Does it Matter
Middle schoolers participate in experiments to visualize the differences between chemical and physical changes. They attempt to detect the five characteristics of a chemical change.

Explaining Change Processes Using a Simple Particle Model of Matter
The more things change, the more they stay the same. This unit includes seven lessons starting with physical change and moving through to chemical change. Conservation of matter is explained clearly with multiple hands-on activities and...

What's the Matter?
Students explore the components of matter. They discover what matter is, the states of matter, and how heat and cold cause it to change states in an online format. In addition, they complete internet-based lessons, activities, and quizzes.

Matter/Solid Liquid Gas Experiments
Students investigate matter:solid, liquid, gas by conducting different experiments. In this states of matter lesson, students conduct hands on activities that allow students to see first hand results. Students mix different substances...

What in the World is Matter?
How does matter change and what are its properties? This presentation is a bit scattered and attempts to infuse humor in place of concrete definitions. In order to make this worthwhile for classroom use, you will need to add to it.

From Gas to Liquid to Solid
From gas to liquid condensation to solid frost, water undergoes phase changes before young scholars' eyes! Using ice, salt, water, and a metal can, they set up an investigation that can be used in a physical science setting, or as part...

Condensation
It's time to break the ice! If you are doing all of the lessons in the unit, children have already seen that increasing heat increases the rate of evaporation, but is the opposite true? Does decreasing temperature cause more condensation...

Evaporation
This is one in several lessons that explore the relationship between temperature and phase changes of water. After some discussion, elementary physical scientists place wet paper toweling on a hot and a room-temperature water bag and...

Matter
First graders study and define matter. They observe and identify states of matter along with common attributes and study how matter can change form or change its state depending on temperature.
