Thinking about signing up as a substitute teacher? Subbing is not for the faint of heart but with the help of the thoughtful advice in a detailed guide, you can develop the skills you need to be a great, professional substitute teacher.

Information about what solids are and properties associated with solid matter.

This article describes the global problem of waste and some of the sustainable waste management projects that the World Bank supports. Includes a link to a report called "What a Waste 2.0: A Global Snapshot of Solid Waste Management to...

Learn more about platonic sold geometry, understand the platonic solid names, view some solved examples, and try your hand at some interactive problems.

A collection of cartoon animations that teach students what they need to understand about solids, liquids, and gases.

Chem4Kids provides an overview of the solid state of matter that explores the characteristics of solids as well as how matter in other states becomes a solid.

Background information: This activity is an extension of the children's exposure to states of matter in the Scott Foresman science series for Grade 2. This lesson plan has a Literacy component. Using the book by Dr. Seuss, "Bartholomew...

Students learn about solids, liquids, and gases in this interactive slide show. Animated cartoon characters explain concepts having to do with properties of matter. A self-checking quiz follows the lesson.

Descriptive details are used as young scholars 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.

Given descriptions, scenarios, or illustrations, students will distinguish between the compressibility, structure, shape, and volume of solids, liquids, and gases.

Read how solids and liquids respond to thermal expansion and learn how to calculate thermal expansion. Formulas and examples are provided.

Get answers to common questions about solids. Understand types of solids and crystal structure with the aid of this FAQ.

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

A good place to learn about current issues in the solid wastes world. Two of the most useful sections are "hot topics" and "contact us", both of which can be used to find out more about municipal solid waste management.

This site gives a description of platonic solids along with a visual representation of each of the five platonic solids. At the bottom of the page are links to cut-out-templates for each of the platonic solids. Be sure to follow the...

The 'Platonic solids' are three-dimensional shapes formed by putting together identical regular faces. Every corner and every edge is identical to every other corner and edge. There are five such 'solids': the tetrahedron, cube,...

In this lesson, students explore solid waste and its effects on the environment. They will collect classroom trash for analysis and build model landfills in order to understand the process and impact of solid waste management. Students...

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:...
