From Gas to Liquid to Solid
From gas to liquid condensation to solid frost, water undergoes phase changes before students' 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 of a...

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...

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...

A New Phase In Town
Middle schoolers explore heat energy and how it is used to change the phase of matter, and discover that temperature does not increase or decrease until the phase change is complete. This extremely well-written plan is packed with great...
Curated OER
States of Matter Lesson
Second graders identify the three phases of matter and demonstrate how a property can change states of matter. In this states of matter lesson, 2nd graders make an Ooze to discover how a solid changes into a liquid. Students...

Exploring Moisture on the Outside of a Cold Cup: For Dry Environments
If the area you live in is arid, or the preceding experiment in this unit didn't yield obvious results, use this one in place of it to help reveal where condensation comes from. The mini unit that this is part of a comprehensive...
Curated OER
Water and Ice
Students will observe, measure and describe the phase changes of ice. In this science lesson plan, students observe ice as it changes phases. Qualaitative notations made by individual students will be shared and compared.

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...

Exploring Moisture on the Outside of a Cold Cup
As a stand-alone or as part of the intended unit, this is a valid investigation of what causes condensation to occur. By limiting the amount of air around a cold cup of water and comparing it to one out in the open, they find that...

Ice Cream in a Bag
Students observe phase change of matter by making ice cream in bags. In this states of matter lesson, students work in pairs to churn their own ice cream in plastic bags. They make predictions about how long it will take for the milk to...

BioFuels: The Chemistry and Economics of Alternative Fuels
Junior chemists manufacture biodiesel in the lab. For this exercise, they check the purity of the biodiesel using thin layer chromatography. They also calculate its density and heat of combustion. They are sure to rise to the...

Changing States of Matter: Water’s Phase Changes
Third graders observe the properties of water and in its different states. In this states of matter lesson, 3rd graders view a video, read The Magic School Bus at the Waterworks and experiment with freezing, melting and boiling...
Curated OER
Chemquest: Physical Changes or Chemical Reactions
Students explore physical and chemical changes. In this chemistry lesson plan, students will go outside to observe changes seen in nature. Students will then work in the lab to identify changes at different stations prior to doing a...

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...

Gases Matter
Young scientists learn that seeing isn't necessarily believing when it comes to the states of matter. After performing a fun class demonstration that models the difference between solids, liquids, and gases, children complete a series of...
Curated OER
States of Matter
Students explore the states of matter. They discuss the different phrases of matter and categorize everyday substances as solids, liquids, or gases. Students explore the relationship between the phases on an atomic level and the role of...

A Matter of State
Students conduct science experiments to understand that particle movement changes as a substance changes from one phase to another phase. Students record observations of experiments that involve the three states of matter: solid,...
Curated OER
Edible Transformations
Students differentiate the different phases of matter. In this chemistry lesson, students conduct several hands-on exercises to discover how matter transforms when mixed together. They identify the different stages in the water cycle.
Curated OER
Warming by Freezing
Ninth graders discover the reasoning behind spraying water on fruit and seedlings in preparation for hard freezes. In this conceptual physics lesson, 9th graders conduct an experiment to measure the heat released when water goes from a...
Curated OER
Nothing New? A Physical Change
Fifth graders discuss the differences between chemical and physical changes. In groups, they complete experiments and discover how a physical chnage can be reversed. To end the lesson, they review the steps of the water cycle and...
Curated OER
States of Matter
Student explore states of matter. In this science lesson plan, young scholars define matter, identify the states of matter, tell about the properties of each state of matter, and demonstrate an understanding of the difference between a...
Curated OER
Physical and Chemical Properties of Matter
Learners identify the physical and chemical properties of matter. They review the types of matter. Students list the four states of matter (Solid, Liquid, Gas and Plasma). They recognize and describe the different types of matter.
Curated OER
States of Matter
Students discover states of matter. In this science lesson plan, students define matter, identify states of matter, explain properties of matter, and demonstrate the various uses of the states of matter.
