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...

A seven-question quiz will help you practice answering questions dealing with the volume and area of solids.

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

Students observe and describe, on the molecular level, how heating and cooling affect the motion of molecules in a solid.

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.

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.

This lesson focuses on solids, liquids, and gases. It has several review activities and an exciting lab experiment involving ice cream to complete the lesson.

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.

First graders observe water changing states from a solid to a liquid to a gas.

[Free Registration/Login may be required to access all resource tools.] This study guide looks at the definitions and postulates of surface area and volume for different solids, including composite solids and similar solids.

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.

Learn all the aspects of waste management including recycling and solid waste disposal.

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...

In this activity, students explore the idea of biodegradability by building and observing a model landfill. This serves as an introduction to the idea of composting. Students learn about the role of engineering in solid waste management.

[Free Registration/Login may be required to access all resource tools.] This study guide reviews how to classify polyhedra, Euler's formula, and regular polyhedra.

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.
