Science 4 Inquiry
States and Phases of Matter
Plasma is the most common phase of matter in our universe. Scholars explore the change of energy as molecules change phases of matter. They rotate through stations, graphing the changes in energy level.

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...

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...

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...

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 activity, 2nd graders make an Ooze to discover how a solid changes into a liquid. Students...

Nanotechnology Invention and Design: Phase Changes, Energy, and Crystals
What does it take to be considered a smart material? Learners investigate the properties of Nitinol, a smart material, through a hands-on lab activity. They examine the crystal lattice structure and the conditions required for Nitinol to...

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...

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...

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...

The Law of Conservation of Matter
The Law of Conservation of Matter can be complex for young scientists to fully grasp. Use this experiment to help simplify the process as pupils perform two experiments to determine mass: one that melts a substance and the other that...

Putting the Ice in Hockey
Eighth grade physical science classes examine why the ice on which hockey is played is slippery. They do so by discussing phases of matter and the molecular motion in each. They read an article on a website and write out answers to...

Exploring Phases of Matter
Students discuss and experiment with the phases of water.  In this phases of matter lesson, students recognize the different states of matter.  Students measure and record changes and understand when the state changes.

Phases of Matter
Young scholars comprehend the different phases of matter.  They give examples of each phase and describe the processes of changing between these phases.  Students are asked what is plasma?  They are asked what is the four phases of...

Melting, Freezing, and More!: Phase Transitions
Third graders listen to a talk on phase transitions and view three demonstrations. In this phases of matter lesson, 3rd graders complete a worksheet as they listen about phase transitions. They move through three demonstrations of phase...

It's The States of Matter
Students investigate the properties of solids, liquids and gases. In this states of matter lesson plan, students observe dry ice and its characteristics. They calculate the density of dry ice and observe the sublimation of the dry ice...

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...

Phases of Matter
Eighth graders practice using correct vocabulary  and apply content knowledge related to phases of matter when answering questions about situations or observations from everyday life.

Edible Transformations
Learners differentiate the different phases of matter. For 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.

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...

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...

Changes in Ecosystems
How does water pollution affect the environment? Provide your class with the resources to answer this question as they learn about eutrophication and ecosystem changes. Over two weeks, they simulate the effects of pollution on the...

Heat Transfer & Phase Changes
In this heat transfer and phase change worksheet, students experiment with ice, salt, and milk to show the relationship between the temperature of a solution and its phase. Students turn milk from a liquid to a solid and graph the...
Curated OER
States of Matter
Young scholars 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...
