Eighth graders analyze questions posted on a large poster in the room and work in groups to record their response to the question on paper, rotating to the next question after two minutes have passed. They review the characteristics of...

Students examine and discuss how atoms change from solid to liquid to gas. They inflate a balloon by melting ice that converts to steam, and discuss the results.

Second graders learn the proper way to take measurements, explore the properties of objects and expand their vocabulary.

For this states of matter chemistry word search worksheet, middle schoolers locate and circle the 20 chemistry terms in the word search puzzle.

Eighth graders identify the types of bonds elements form. In this chemistry lesson, 8th graders represent valence electrons with dot structures. They draw and label different atoms.

Students complete a unit of activities to learn about states of matter and how to measure matter. In this matter lesson, students complete 8 lessons to learn about matter, its states, and how to measure matter.

Students observe the 'pouring' of a gas. They compare the masses (weights) and densities of two gases. Pupils define the following terms: matter, mass, and density. Students answer questions after watching the demonstration.

Second graders investigate the properties of solids and discover how to classify them. Using rulers, they measure various solids on display. In groups, they play an identification game where one students names a location, such as the...

Tenth graders observe the processes of evaporation, condensation, melting, freezing, boiling, and sublimation. They do a quantitative investigation of the freezing of water, to explore explanations that involve particles.

Students break into four groups, starting at different stations. Each station should take about 10 minutes depending on prior knowledge of the topic. They then rotate when everyone is finished to the next station and discuss answers of...

Students test different objects such as dominoes, marshmallows, slides, and more to test their force, motion, gravity, friction, and the concept of matter. In this force and motion lesson plan, students understand that the force an...

Students complete activities to study the properties of solids and liquids. In this states of matter lesson, students investigate the melting and freezing of a range of materials in a virtual experiment. Students melt the substances and...

What's the solution to gaining insight into your class' progress? Give this brief quiz a try! Part 10 of a 14-installment series on states of matter tests learners' skills in the areas of dilution and the properties of water,...

As the title implies, this PowerPoint defines and illustrates the basic terms involved with describing matter. Phases of matter, atomic structure, and the different categories of compounds are included. Slides are simple and uncluttered....

Learners experiment with various foods to determine fat and starch content. They rub jam, peanut butter, bananas, and other foods in a small circle on a piece of paper, and observe the results. If there is a high fat content in the...

Don't be fooled by the title; this is not really a lesson on elements. It is a project on classification, using the periodic table as an example. For that reason, it could be used in any branch of science. As an example, a group may...

By viewing this PowerPoint your students' understanding of molecular energy should increase. The properties and inter-particular forces are summarized. The logical progression of information is useful, but more data to demonstrate...

In this matter worksheet, students complete a graphic organizer by describing the properties of matter, the changes of matter, and how matter can form mixtures.

Roll up your sleeves and get a little dirty with this elementary and middle school compost instructional activity. All you need is a large plastic container, a couple old newspapers, some organic waste, and a few hundred worms and...

Determining whether or not something is living can be more difficult than it seems. Put your young scientists to work defining their own criteria to identify life, then work with three samples to see if they are alive or...

Tiny bubbles, in my...clouds? Offer youngsters a hands-on, visual learning experience when reviewing the scientific concepts of condensation, water vapor, and the collection of droplets that make up clouds.

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. 

Rain, rain, go away—wait, there it is again! Elementary scientists learn how rain works its way through the stages of the water cycle with a series of classroom lessons and hands-on activities.

Young scholars study the process of water filtration in a three-part STEM lesson. After analyzing samples of dirty water, teams design and build their own filtration systems and measure their efficiency.
