Descriptive details are used as students develop a guessing game poster for others to try and guess their chosen solid. Included in this detailed lesson plan are videos, samples of student work, a printable worksheet, an assessment...

In this article, you can learn about solid wastes. It discusses the problems associated with disposal and possible solutions.

Lesson introducing the basic three-dimensional shapes (sphere, cylinder, cone, cube). Common items with those shapes are hidden on the playground for students to find and photograph. Pictures are then used to create a photostory....

This tool allows you to manipulate various geometric solids and investigate their properties.

See how the cross-sections of solids relate to their shapes.

Explore the volume of solid figures.

Investigate the properties of a strange substance which acts like a liquid and a solid. This simple experiment can be done with corn starch and water.

See how different solids can have different densities depending on their molecular make-up.

Quiz your knowledge of three-dimensional figures, specifically volume and surface area, with this sixteen-question practice exercise.

What causes frost to form on the outside of a cold container? In this activity, students will see that the liquid water can change state again and freeze to become ice.

Kid's learn about the science of states of matter. Solids, liquids, gases, and even plasma.

This interactive assessment features 7 matching, 7 multiple-choice, and 6 true/false questions over 20 terms related to Solids, Liquids, and Gases (the three states of matter).

This set of interactive flashcards focuses on 20 terms related to Solids, Liquids, and Gases (the three states of matter).

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

Observe the differences between solids, liquids and gases.

"A centrifuge separates a heterogeneous mixture of solid and liquid by spinning it." Use this site to find out how to correctly use a centrifuge in this informative site.

This resource has three sets of problems. Each set has six questions for finding volumes of solid figures. Select a problem set, then select a question. Fill in the blank with the correct answer for each problem. When you have answered...

A simple lab experiment for students to find the density of two solids and a liquid (does not use water displacement). Note that number 1d should not state "weighs" since mass is being found.

A lesson in creating 3-D solids using toothpicks and marshmallows.

You know that water can exist in three separate phases: solid (ice), liquid (water), and vapor (steam). To change from one phase to another, you simply add (or remove) heat. When water boils, what happens to molecules (for example sugar...

Watch different types of molecules form a solid, liquid, or gas. Add or remove heat and watch the phase change. Change the temperature or volume of a container and see a pressure-temperature diagram respond in real time. Relate the...

Through an instructional video, games, and activities, students explore three types of change matter makes: physical change, in which only the shape of the matter changes; physical phase change in which matter changes to a different form...

Learn about sound waves, which move vibrations from one place to another through liquids, gases and solids, with this interactive lesson.

A very detailed lesson on determining the volume of rectangular prisms, teaching students how to derive the formula for volume, and to use it successfully. Plenty of examples, student work, and assessment options.
