Science Experiments

Busy is (and always has been) fascinated with science experiments. Any kind of experiment, really. These are a few of our favorites that never disappoint.

Tie-dyed Milk

What You Need

  • milk
  • tooth pick
  • dish soap
  • container for the milk
  • small dish for the soap
What To Do
  1. Pour 1/2 an inch of milk into the container
  2. Drop 2-3 drops of food coloring per spot around the container
  3. Dip the toothpick in the dish soap then dip it in the center of a color spot.
  4. Watch the reaction then repeat with each color spot. 
  5. After the reactions are complete, you can swirl all the colors together to make a rainbow :)

Sink or Float?

What You Need 
  • water
  • a container for the water
  • various items that sink and float
  • a place to record your findings (optional depending on age)
  • aluminum foil for making boats after the experiment :)
What To Do
  1. Fill the container with water
  2. Make your predictions about each item before the experiment begins
  3. put each item in the water to test your predictions 
  4. record and discuss your findings
  5. After the experiment we made foil boats to see which items could in fact float with a little help from a boat. 

What You Need
  • Corn Starch
  • Water
  • container
  • Optional things for testing - glitter, scented extracts, food coloring
What To Do
  1. Mix the corn starch and water until you get a substance that acts like a solid when force is applied and acts like a liquid when you let it run through your fingers. 
  2. We also enjoyed mixing a little peppermint extract and glitter! Busy liked it so much that we decided to give some of her friends a little oobleck in a small mason jar for Christmas! 
  3. You can also make it any color or scent you like. 

What You Need
  • vinegar
  • baking soda
  • food coloring 
  • a clear cup
  • a shallow container
What To Do
  1. Put about 1/4 of a cup of baking soda in the clear cup and put the cup in the shallow dish (this is also when we added the food coloring)
  2. Pour a splash of vinegar into the cup and watch it bubble up and spill over the cup edge (this is why the cup is in a shallow dish)
  3. Do this over and over again until all of the baking soda has reacted. 

What You Need 
  • 1/2 cup of clear glue
  • 1/2 cup of liquid starch
  • food coloring
  • a medium sized bowl
What To Do
  1. Mix the glue and starch together in the bowl for a bit then use your hands to finish mixing. 
  2. Once the slime has formed, add the food coloring. You can use one or more colors. We like using two primary colors and mixing until another color appears :)
*Note - If you need more or less slime, the recipe is simply equal parts clear glue and liquid starch*
