 * Remind your children that everything is made of matter. Matter is anything that takes up space and it is made up of tiny particles. Matter can come in different states, or forms, such as solids, liquids, and gases. Different types of energy, including heat, can change matter. Matter can change states through freezing, melting, evaporation, and condensation.

 * Different kinds of energy can cause matter to change states. Most children have experience with ice cream melting on a hot day or ice cubes melting in a glass. When a substance melts, it goes from a solid to a liquid. Heat causes the temperature of the substance to increase and particles to gain more energy. They are able to move faster and flow, causing a solid to change into a liquid. (Use ice cream to show how things change when heated)
 * Many children have poured liquid water into an ice cube tray and put it in the freezer to make ice, which is a solid. When a substance freezes, it loses heat and energy. Particles slow down and become more packed together. This causes liquids to change into solids. The freezing point of water is 32 degrees Fahrenheit. Different substances have different freezing points. (Activity; Do all liquids freeze at the same rate? Do an experiment to find out together! Find or make different liquids with your child, such as water, milk, juice, rubbing alcohol, and saltwater. Pour small amounts of different liquids into labeled cups. Then put them in the freezer. Every fifteen minutes, have your child check on the liquids. Which freezes the fastest? Which is the slowest? Have your class make predictions and discuss results)
 * Describe changes in matter when mixed with water. Make predictions of what will happen when rocks, soil, and oil are mixed in water. Mix water with rocks. Mix water with soil. Mix water with oil. Talk about what happened and why.

__Assessment-these may be written, verbal, observations, etc__:

 * observation of discussion
