INTERACTIVE SITE on STATES of MATTER
View The HARCOURTSCHOOL interactive website to see examples of the three states of matter. http://www.harcourtschool.com/activity/states_of_matter/ it has an excellent interactive visual. It also help students when they are dramatizing the movement of the particles in a solid, liquid, and a gas.
You could either pre-cut or have students cut pictures from magazines representing the three states of matter and have them place them under the correct headings of SOLIDS, LIQUIDS and GASES.
EXPERIMENT with Water :
Changing from a solid to a liquid
1. Prepare ice cubes of equal volume ahead of time by pouring the same amount of water into different shaped containers such as ice cube trays, paper cups with flat and/or pointed bottoms, Popsicle molds, cupcake or cookie molds, etc.
2. Show the cubes to the students, asking them to predict the melting times of the different shapes of ice. (Ones with greater surface area may melt faster.)
3. Have the students mix a small amount of water with the salt and set it aside to evaporate in a dark colored container so that students can see the salt crystals that will be left behind. This will take a few days to evaporate.
