Eye of newt, hair of toad, we really hope you don’t explode!
It’s time to mix it up with a few exciting chemistry experiments! What is chemistry? Chemistry is the study of matter and the changes that take place with that matter. Matter makes up everything.
Chemistry looks at the ways matter changes and transforms to create the Universe that you know. Everything in the Universe is made up of Matter. Matter is the name that scientists have given to everything that you can touch, see, feel, or smell.
Chemical reactions are reactions that take place between two or more chemicals, which create something different. Everything is made up of chemicals including you, your pets, the stars, and even your kitchen table. We want you to have a blast with this group of activities exploring chemical reactions-just don't blow up the basement!
MATERIALS:
• Whole Milk
• Styrofoam dinner plate 9 inch
• Food coloring (red, yellow, green, blue) • Dish washing soap
• Cotton Swabs
PROCEDURE:
1. Pour enough milk in the dinner plate to completely cover the bottom to the depth of about 1⁄4 inch.
2. Allow the milk to settle.
3. Carefully place one small drop of each of the food colors on the surface of the milk – evenly space
4. Keep the food colors close together inthe center of the plate of milk.
5. Take a clean cotton swab for the next part of the
6. Experiment and touch the tip of the cotton swab to the center of the milk. Do not stir the mix.
7. Now place a drop of liquid soap onthe other end of the cotton swab. Place the soapy end of the cotton swab back in the middle of the milk and hold it there for 10-15 seconds.
8. Prepare to observe the changes.
Mermaids are mythical half-human sea creatures with the upper body of a girl or woman and the tail of a fish. Mermaids are mentioned in sea folklores and are usually depicted as beautiful and gentle creatures that guide sailors and others travelling through the seas. If you are going to make slime, why not mermaid slime?
MATERIALS:
• 5oz. bottles clear Elmer’s glue
• Borax Powder
• Water
• 2 drops of blue food coloring • Glitter
PROCEDURE:
1. Mix 1 teaspoon of borax powder with 1⁄2 cup of water.
2. Mix 5 ounces of glue, food coloring, the glitter, and 1⁄2 cup of water to a second container.
3. Add the borax water to the glue mixture and stir until completely mixed.
4. Mix and knead, checking consistency, and adding more glue or borax solution as needed.
Get ready for some tactile fun! Asteroids are chunks of rock and metal in outer space that tumble and spin while orbiting the sun. As you make your own asteroids, remember most are not perfectly round, but lumpy!
INGREDIENTS:
• A box of baking soda
• Red and green food coloring
• Black and silver glitter
• White vinegar • Water
Pour the box of baking soda into a plastic container or large bowl. Sprinkle the glitters over the baking soda and mix together. In a cup, combine 1⁄2 a cup of water with two drops each of red and green food coloring. Slowly add some colored water to the baking soda. Use your hands to form asteroid shapes out of the wet bakingsoda. Be careful not to use too much water, the baking soda willdissolve. Place your asteroids in a warm spot so they will dry and harden. This may take a couple days. Warning, the next step is fun and MESSY! Once they are dry, put your asteroids back in the plastic container and dribble vinegar over the asteroids.

Making rock candy at home is really easy and lots of fun!
This activity is a beautiful Science experiment and a yummy treat all in one. Check on your jars each day to see if the rock crystals had grown.
MATERIALS:
• 2-3 cups of sugar
• 1 cup of water
• Skewers/candy sticks • A jar or glass
• A large saucepan
• Clothespins
Optional additions
• Food coloring and candy flavoring
Note: You can easily double and triple the above recipe. You might want to make a whole rainbow of rock candy colors. Try using 10 cups of water and close to 30 cups of sugar. As long as the sugar to water ration is close to 3:1 the rock candy will grow.
PROCEDURE:
1. Combine equal parts of sugar and water in a saucepan and heat until all of the sugar is dissolved
2. Then slowly add more sugar in small amounts until it will no longer dissolve in the water
3. The water should start to look a little cloudy. That is the point when no more sugar is dissolving and the perfect sugar saturation has been reached. Basically, you are
creating a saturated sugar solution (a solution in which no more sugar can dissolve at a particular temperature) The amount of sugar verses water used should be roughly 3:1. Add candy flavoring if desired, and then continue to heat the water until it comes to a simmer.
4. Remove the sugar-water from the heat and allow it to cool. While it is cooling you can prepare your skewers or candy sticks. Cut the skewers to a desirable size for the jars you are using. Then dip the sticks in water and roll them in sugar
5. Allow the sugar coated sticks to dry. While those are drying you can prep your jar(s). Once your sugar-water is cool enough pour it into jars and add food-coloring if desired. Then, once the sticks are dry place them in the jar(s).
6. You want to make sure that the sugar coated sticks are completely dry before placing them in the jars. The rock candy needs the sugar to grow on, and if the sugar on the sticks isn't dry it will dissolve in the water. It is also important to make sure that the sticks are not touching the bottom or sides of the jar
That's it! It is now time to sit back and observe the jars.
