Explore the properties of gases through one activity and two investigations in which super scientists observe the changes gas makes when encountering different conditions.

Have some physical science fun when studying the center of gravity or center of mass. Simply have balancing artists stand a dowel on one finger and keep it from falling over! A lump of clay is added and moved up along the dowel over a...

Do you think the lab smells like rotten eggs? Sorry to hear about your sulfering. A set of five experiments covers many different topics including seasons, gravity, food, precipitation, and photosynthesis. Though not presented as a...

Is your class in the dark about photosynthesis? Shed some sunlight on an important biological process with a thoughtful activity. After answering questions to help determine their level of knowledge, learners work with chemical equations...

Your young environmentalists can calculate their carbon footprint and discuss ways to reduce it with a worksheet about climate change. After reading a handout about what impact one's carbon footprint can have on the environment, kids...

Get hands-on in your physical science class by having learners conduct electricity with their own hands! By placing one hand on each of two different metals, a current can be generated and measured on a microammeter. Make an experiement...

Students investigate bio-fuel. In this investigative lesson, students create bio-fuel from vegetable oil waste. Students will analyze, predict, collect and synthesize data from their experiments with bio-fuel.

Step into Dirtmeister's Science Lab as he explores the challenge question: "How can you force a physical change in matter?" Learn about matter, make your predictions and then do the experiment.

Can you distinguish physical changes from chemical reactions? You'll be presented with a number of pictures and asked to identify those which are examples of chemical reactions.

Brief descriptions of physical properties, physical changes, and the process of sublimation. The three states of matter, melting point, and boiling point are described. There is one link on the page, which leads to an explanation of...

An online flashcard deck that reviews properties of matter. Test your knowledge of matter, chemical changes, and physical changes. Site allows you to put flashcards into two sections, those you know and those you don't. After separating...

A laboratory experiment where students classify matter into a homogenous mixture, heterogeneous mixture, solution, or pure substance. Also students will test for physical and chemical changes.

Help the Phantom choose a material and observe the changes at different temperatures in the molecule chamber. What happens to the elements or molecules as the temperature changes?

[Free Registration/Login Required] An informational text about how cooking causes changes in matter. A question sheet is available to help students build skills in reading comprehension.

The chemical change of matter is illustrated in this lab experiment when spaghetti is placed in a solution of baking soda and vinegar. Watch the spaghetti rise to the surface and sink again once the gas is released.

Students will practice the technique of chromatography by separating a mixture of FD&C dyes. Questions related to the experiment along with the answers are available for use by the teacher.

In this experiment, three reactions are performed in a sealed Ziploc bag so that they can be observed. Students identify whether physical or chemical change has taken place.
