Why is it so difficult to make two solid compounds react? Investigate the concepts of particle collisions and rate of reaction using a quick demonstration. The colorful experiment features two plain, white solids combining to form a...

Delve into the differences among solids, liquids, and gases with this PowerPoint. It is both applicable and attractive. Large, colorful diagrams display the molecular arrangement of each state of matter and their properties are arranged...

In this phases of matter worksheet, learners complete 13 fill in the blank spaces with science words from the given word bank. The blanks are placed within an informational paragraph about solids, liquids, and gases. 

Investigate the properties of solid and liquid materials. This very complete slide show is perfect for introducing liquids and solids to children in grades one or two. It describes multiple properties of solids, metals, plastics, wood,...

Students investigate community issues with solid waste. In this mock trial lesson, students examine the issues of solid waste from an ecological and economical perspective. They will develop a mock trial which encourages preservation of...

Review the states of matter with your second graders using this resource. Learners first review what they know about solids, liquids, and gases. Then, they fill out a chart to show what they have learned. Finally, they engage in a...

Not many lessons on states of matter can hold a candle to this one! Junior chemists gauge the density of paraffin in both liquid and solid phases. They fill 60 mL syringes with different materials to experiment with compressibility and...

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...

Though it comprises only 5 percent of the world's population, the US generates 40 percent of the world's waste. Scholars learn about landfills, their safety, and other solid waste methods. They use experiments and research to learn more....

Third graders experiment with common household liquids and solids. In this chemical reaction lesson, 3rd graders discuss phase changes and experiment to find other ways to create gases. They use water, vinegar, lemon juice, flour, baking...

Students review the vocabulary terms solid and liquid. They also review that adjectives tell what kind, which one, and how many. The teacher introduces a "Oobleck" after reading "Bartholomew and the Oobleck" by Dr. Seuss. The students...

Crystal comes from a Greek word meaning ice. Activity eight in a series of 36 has class members analyzing amorphous and crystalline solids and further classifying them based on their forces. They then explore solids, learning about unit...

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...

There's a container for every matter—liquid, solid, and gas. Pupils design three different containers, each with the capability to hold one of the states of matter, and share their design with the class.     

Time to show what they know! Module five in a 14-part series about solids, liquids, and gases redirects to an interactive quiz. Learners test their skills on topics such as states of matter, phase changes, and Brownian Motion. With...

Here's a tip: only one substance is commonly found as a solid, liquid, and gas. Learners use that knowledge as they investigate the properties of water in each state. They interact with water in each of its three phases and record what...

Students investigate the properties of plastic eggs filled with solids, liquids, and gases and use these observations to hypothesize whether a chicken egg is hard-boiled or raw.

Students explore and identify phases of matter and compare the particle motion in solids, liquids, and gasses.

Scientists participate in a variety of hands-on experiments in this ten-day unit on the three states of matter. Lessons incorporate literature, a-v materials, and poetry to help students differentiate between solids, liquids and gases.

Students explore solid waste and its effects on the environment. They explain some of the major problems caused by waste disposal and the use of landfills. They suggest ways to reduce the amount of solid waste going into a landfill.

In this dissolving solids and gases activity, high schoolers learn that the process of dissolving gas is opposite of the process of dissolving solids. Students answer 3 critical thinking questions about dissolving gases and solids in...

Learners construct models of the way water molecules arrange themselves in three physical states - solid, liquid, and gas. They explain the molecular behavior of ice, water, and water vapor.

Students conduct an online experiment to discover what happens to solids, liquids and gases in different temperatures. In this states of matter lesson, students get into pairs and work in a virtual laboratory to manipulate...

Young scholars are introduced to the various states of matter. After watching a video, they discover how to compare the three states using its shape and volume. In groups, they participate in an experiment with solids, liquids and...
