This activity reviews of states of matter, then relates them to atomic movement as it is affected by attractions between atoms and the addition of energy. Latent heat and evaporative cooling are also topics covered. Multiple-choice and...

Learn about matter, its three states, changes of state, how matter behaves, and physical and chemical changes in matter.

In this lesson, students 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 devising how...

[Free Registration/Login may be required to access all resource tools.] Freshly baked bread and cherry pie are two delicious parts of any meal. What happens to the ingredients that go into the bread and the pie as they are heated in the...

Five chemistry lessons about phase changes between the states of mattter complete with handouts and animations.

Learners conduct a hands-on investigation to determine how matter, changing state, effects the property of weight. Students will collect data and graph their results. Resources include step by step instructions, a data worksheet, videos...

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.

The class will go back over the Power Point presentation on chemical and physical properties. The teacher will then conduct numerous liquid nitrogen demos. This instructional activity is used early in the Chemistry course. The students...

Students build a model of a water molecule and design an experiment to see if adding energy affects the rate of evaporation.

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.

Learn how states of matter can change as heat is added to a system.

In this chemistry lab, students will investigate, observe, and describe a variety of chemical and physical changes in matter. They will understand that this is part of everyday life.

This resource explains the five states of matter and methods of changing from one state to another.

Change variables in this simulation to see how compression affects different states of matter.

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...

Students investigate how low temperature causes water vapor to condense into a liquid and then freeze to form a solid.

A released question from the Trends in International Mathematics and Science Study (TIMSS) assessment about change of states of matter. Also included is a scoring guide for the released question.

[Free Registration/Login may be required to access all resource tools.] In this online tutorial, students will begin to understand a substance according to its physical properties. Learn to distinguish between extensive and intensive...

[Free Registration/Login may be required to access all resource tools.] In the following online tutorial students identify the chemical properties of a substance and describe chemical changes and differentiate them from physical changes....

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.

Matter changes both physically and chemically on a fairly regular basis. Through these activities students will challenge their understanding of the changes that may take place with different types of matter.

Join a group of middle-school students on a visit to a laboratory at the Massachusetts Institute of Technology, where they experiment with "mystery mud" and learn about the relationships between magnetism, particle motion, and changes in...

This lesson focuses on the states of matter: solids, liquids, and gases. It also discusses the Kinetic Theory of Matter, Thermodynamics, Triple point, Phase Change Graphs and the Heating Curve of Water. It provideds adrawing of a heating...

Discusses the changes of state that can occur for the three different types of matter (solids, liquids, and gases) and different types of heat energy that have been defined by scientists.
