This folder includes lab sheets for 6 different experiments involving the states of matter (solid, liquid, gas). The experiments include:
--Ice Cubes: Watching the change between states of matter. This simple experiment shows students how something can change states. I recommend putting the ice cubes in a plastic bag and taped to a window to see it in all three states at the same time (water vapor forms on the bag) and then transferring it to a plate to watch it evaporate completely.
--Bubbles: Are the more like a solid, liquid, or gas? Students use what they know about each state to examine bubbles and determine which state they resemble the most. This type of experiment is great for forming opinions and debates and allows students to access higher-order thinking.
--Clay: Is it more like a solid or liquid? (same as above). I recommend giving each student a ball of clay and a small cup to see that it can take the shape of its container, like a liquid. We then discussed what happens to clay after it is left out overnight and what ingredient it must have to allow it to change shape so easily.
--Cornstarch Goo: Is it more like a solid or liquid? (same as above). I gave each group of 5-6 students a mixing bowl, one box of cornstarch, food coloring to make it look more appealing, and about a cup and a half of water to mix in. When students squeeze the mixture, it holds its shape and then seeps through your fingers like a liquid.
--Making Popsicles: Changing from a liquid to a solid. I recommend using small dixie cups and Kool-Aid.
--Vinegar and Baking Soda: Changing from a liquid to a gas. I recommend having students work in partners or small groups to mix the two ingredients together. Add food coloring to the vinegar for an extra visually appealing experiment.
