Middle School Chemistry: Changing State: Melting
Discover the concept that energy transfer and molecular motion cause the change in state from a solid to a liquid. Also compare state changes of water to the state changes of other substances.
American Chemical Society
Middle School Chemistry: Changing State: Evaporation
Students build a model of a water molecule and design an experiment to see if adding energy affects the rate of evaporation.
American Chemical Society
Middle School Chemistry: Changing State: Freezing
Students investigate how low temperature causes water vapor to condense into a liquid and then freeze to form a solid.

Serc: Exploring States of Matter Gases
In this series of chemistry labs, students learn about the three states of matter by observing how molecules contract or expand as they change state.
Utah STEM Foundation
Utah Stem Action Center: Changes in Matter
The goal of this activity is to develop and use a model to describe that matter is made of particles on a scale that is too small to be seen. You will be making observations of changes supported by a particle model of matter.

Serc: Changing the State of Matter Using Heating and Cooling
In this lesson, young scholars will investigate how different materials changed when heated or cooled. The process in developing the investigation will be inquiry based. Students will have the liberty in choosing the materials and...
Children's Museum
The Children's Museum of Indianapolis: Color Changing Milk
Students observe a molecular dance of bursting colors through exploring states of matter and learning that materials can be characterize by how they respond to water.

Serc: Freezing and Phase Change: How Do You Make Ice Cream?
Students will be expanding a study of phase changes after experiences with exploration of the three phases of matter. They apply what they have learned through freezing water and create a tasty ice cream treat.
Science Education Resource Center at Carleton College
Serc: Observing the Effect of Temperature on Change of State and Gas Pressure
This lab serves as a short introduction to both changes in state and air pressure/the gas laws. The students will heat a small amount of water in an aluminum can. They will then invert it in a bucket of cold water and crush the can using...

Serc: Mn Step: States of Matter
In this activity, students investigate physical and chemical changes in the states of matter for water. They collect data and record their observations.
University of Florida
Florida Museum of Natural History: Kitchen Science
This guide focuses on everyday substances and how we can change their properties by adding heat or cold, physically manipulating them, or mixing them together.
