Changes in Matter

Engage the class like never before as pupils learn to differentiate between multiple physical and chemical changes by conducting a list of small experiments, most often with household materials. They make observations and discuss the...

Plasma is the most common phase of matter in our universe. Scholars explore the change of energy as molecules change phases of matter. They rotate through stations, graphing the changes in energy level.

The heat of solution measures how much thermal energy a dissolving substance consumes or gives off. The experiment demonstrates both endothermic and exothermic reactions. Scholars dissolve several substances, measure the temperature...

Young scientists get to the heart of the matter as they complete this worksheet on the properties of solids, liquids, and gases.

Do solids, liquids, and gases even matter? The presentation focuses on changes in matter, including phases, Boyle's Law, Charles' Law, and physical changes. 

This PowerPoint is a gem! Seventy-eight slides present an entire introduction to matter in bullet-point fashion. Viewers learn about everything from mass and inertia to phase changes and gas laws! The only glitch is that the links to...

In this changes in matter worksheet, students state whether each of following changes would be physical or chemical changes. Students define in their own words each of the following terms in the space given.

Energize your phase change lesson plans! Add a short but focused interactive into the mix and watch as pupils experience how states of matter react to changes in kinetic energy. The resource tracks the kinetic energy of a cold solid...

Young scholars investigate chemical and physical changes. In this chemical and physical changes lesson plan, students distinguish between a chemical and physical change when observing baking bread and hot dogs and bagels cooking on a...

What better way is there to introduce conservation of mass than a few simple experiments? Young chemists conduct two chemical reactions, take the masses of reactants and products, then compare their results to determine differences in mass.
