How To Make Invisible Ink
Sediment flow and delta formation experiment
Materials: 1. Brown sugar 2. 2 zipper-lock bags 3. Half and half 4. Adult supervision 5. Vanilla extract 6. Ice 7. Rock salt 8. Large empty container with lid 8. Measuring utensils Steps: 1. First, fill the large container half full with crushed ice. 2. Next, add 6 tablespoons of rock salt to the ice and seal the container and shake the ice and salt for 5 minutes. 3. Then, mix 1/2 a cup of half and half, 1/2 cup tablespoon brown sugar, and 1 teaspoon of vanilla extract in the zipper bag. 4. Next, tightly seal the bag and place it inside the other zipper bag. 5. Then, place the bag inside the container with the salt and ice. 6. Next, shake the container and the ice cream will be ready in 17 minutes. 7. Finally, remove the bags from the jar and rinse them with water and enjoy! Lesson: Salt causes ice to melt. When salt comes in contact with ice, the freezing point is lowered. Heat must be absorbed by the ice to melt, which means the heat that causes the melting comes from its surroundings. By lowering the temperature at which ice is frozen, you are able to create an environment where the cream could freeze at a freezing temperature to make ice cream.
In a just single teaspoon of soil there are around 5 million single celled organism!
Using the classic baking soda and vinegar demo to blow up a balloon.
Materials: 1. A flat tray 2. Food coloring 3. Whole milk 4. Liquid dish soap Steps: 1. First, pour the milk into the tray. 2. Next, add 6-8 drops of different colored food coloring a onto the milk in different spots. 3. Finally, add 5 drops of liquid dish soap onto the drops of food coloring.

Hi everyone! I'm Ashley P. and I'm a Girl Scout who wants to make a difference in the world. Currently, I've been working on my Gold Award Project, which is a project where Girl Scouts solve an issue in their community to earn the Gold Award. The Gold Award is the highest award a Girl Scout can achieve. In my project, I'm addressing the issue on how there are a lack of women in the STEM field by creating a program to do fun science experiments with younger girls. Also, I constructed this blog for parents and children to do exciting and simple experiments with their kids to spark a passion in this subject like what happened to me as a child. I hope you enjoy and try to accomplish the experiments I post! Also, please have adult supervision while completing these experiments.
