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...

Explore the world of solid shapes in this mini-lesson. Provides a definition, interactive examples, and interesting practice questions that help with understanding.

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

Learn about platonic solids, a special type of polyhedra. Read a definition, make three-dimensional models using printouts, and play with an interactive animation, which will show you the faces, vertices, and edges on platonic 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.

Climates vary and understanding that water on earth reacts to the climate is a way to understand why water can be found as both liquid and solid on earth. Included in this lesson is a video of the activity in action, and an image of a...

This simulation shows conduction of thermal energy within and between solids, based on the kinetic energy of particles, and collisions between neighboring particles.

This simulation shows conduction of thermal energy within and between solids, based on the kinetic energy of particles, and collisions between neighboring particles.

Explore the volume of solid figures.

Did you know that the five regular platonic solids (tetrahedron, octahedron, icosahedron, cube, and dodecahedron) were thought to represent earth, air, fire, water, and the universe? This chart shows an image and provides a description...

Lab activity uses a computer simulation to determine the amount of water in a crystalline solid hydrate.

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

Students are given a variety of materials and asked to identify if each material as a solid, liquid or gas. They use their five senses - sight, sound, smell, texture and taste - to identify the other characteristics of each item.

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.

Determine how the cooking time of cranberry sauce affects its ability to form a pectin-supported solid. The Science Buddies project ideas are set up consistently beginning with an abstract, objective, and introduction, followed by a...

This tutorial is linked to a computer simulation and helps strengthen student's understanding of percentage yield.

Young scholars determine whether an object will sink or float by comparing its density to the density of water.

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

Discover the concept that energy transfer and molecular motion cause the change in state from a solid to a liquid. Also compare state changes of water to the state changes of other substances.

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

Students investigate the concept of a precipitate by combining two clear, colorless solutions that produce a solid.

[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.

In this activity, students explore the concept of "reducing" solid waste and how it relates to product packaging and engineering advancements in packaging materials. Students read about and evaluate the highly publicized packaging...
