Observe reactions that produce gases in this lab activity! Students observe chemical changes as they evaluate the amount of gas produced. This lab activity includes both student and teacher instruction sheets.

The goal of this activity is to develop and use a model to describe that matter is made of particles on a scale that is too small to be seen. You will be making observations of changes supported by a particle model of matter.

Matter changes both physically and chemically on a fairly regular basis. Through these activities students will challenge their understanding of the changes that may take place with different types of matter.

After observing a demonstration of a chemical reaction between a burning candle and the oxygen in the air, students use atom model cut-outs to model the reaction and see that all the atoms in the reactants show up in the products.

Twelve interactive chemistry lessons about chemical changes complete with handouts and animations.

Explains what a physical change is and gives examples. The difference between a physical and a chemical change is also discussed.

This lesson teaches students to distinguish between physical and chemical changes. Students will view an interactive slideshow presentation and then conduct experiments to discern physical and chemical changes.

The teacher will conduct the whoosh bottle demonstration to engage students. The class will then begin discussion of endothermic and exothermic physical and chemical changes. The students will then conduct the Science in Motion lab...

Students study the energy associated with physical and chemical changes. The activity consists of observing nine phenomena.

Join Jacob on the Nova Zembla Expedition, and help him use suitable materials for building his house.

Science fair project tests whether students can construct a shape out of clay that will float.

Students will add 4 chemicals to a beaker and observe the changes that take place. They will classify them as physical or chemical changes.

Students burn a magnesium strip to reinforce the concepts of chemical vs. physical changes, reaction types, conservation of mass, formulas and equations, stoichiometry, Lewis structures, and to explore the concept of oxidation/reduction...

Do you know the difference between a physical and a chemical change? This interactive tutorial will explore these concepts!

Many materials expand when heated and contract when cooled. What do you think will happen to the elasticity (stretchiness) of a rubber band when it is heated or cooled to various temperatures?

The class will go back over the Power Point presentation on chemical and physical properties. The teacher will then conduct numerous liquid nitrogen demos. This instructional activity is used early in the Chemistry course. The students...

[Free Registration/Login may be required to access all resource tools.] Definition of chemical change and examples, signs of chemical change and how it can be reversed.

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.

Students observe reactions of liquids with different known powders in this lesson plan. Unknown powders are then identified using characteristic chemical changes.Site includes a procedure, teacher instructions, and video instruction.

This lesson focuses on how food packages are designed and made. Students will learn three of the main functions of a food package. They will learn what is necessary of the design and materials of a package to keep food clean, protect or...

In this activity, students will observe another aspect of a chemical change which is a change in temperature. In this reaction, students will experiment with an endothermic reaction.

This activity explores how students could use chemical changes to identify unknown substances. Lab activity includes student and teacher worksheets.
