10 Fun Science Experiments at Home

We love doing science experiments in our home. And, the best thing about these science experiments is that you can also modify them and see what happens! Check out what you do to make them work and how things change.


Dancing Milk-From the Arizona Science Center

  • One (1) Dish Soap Bottle
  • At Least Two (2) Different Types of Milk (Whole Milk, 2% Milk, Skim Milk)
  • Water
  • Three (3) Clean Small Bowls
  • One (1) Box of Cotton Swabs
  • One (1) Food Coloring

Crystal Snowflakes- Arizona Science Center

 2 cups boiling water
• 6-8 tablespoons borax
• Large spoon
• 1-2 pipe cleaners for each snowflake
• Scissors
• String
• Glass jars — large enough so a snowflake can hang inside and not touch the sides or bottom; one jar per snowflake is best.
• Pencil or stick — big enough to span the jar opening


Blowing up Balloons with CO2

What you’ll need:

  • Balloon
  • About 40 ml of water (a cup is about 250 ml so you don’t need much)
  • Soft drink bottle
  • Drinking straw
  • Juice from a lemon
  • 1 teaspoon of baking soda

Instructions:

  1. Stretch out the balloon to make it as easy as possible to inflate.
  2. Pour the 40 ml of water into the soft drink bottle.
  3. Add the teaspoon of baking soda and stir it around with the straw until it has dissolved.
  4. Pour the lemon juice in and quickly put the stretched balloon over the mouth of the bottle.

Making Music With Water

What you’ll need:
  • 5 or more drinking glasses or glass bottles
  • water
  • wood stick such as a pencil
  1. Line the glasses up next to each other and fill them with different amounts of water. The first should have just a little water while the last should almost full, the ones in between should have slightly more than the last.
  2. Hit the glass with the least amount of water and observe the sound, then hit the glass with the most water, which makes the higher sound?
  3. Hit the other glasses and see what noise they make, see if you can get a tune going by hitting the glasses in a certain order.

Invisible Ink with Lemon Juice

  • Half a lemon
  • Water
  • Spoon
  • Bowl
  • Cotton bud
  • White paper
  • Lamp or other light bulb
  1. Squeeze some lemon juice into the bowl and add a few drops of water.
  2. Mix the water and lemon juice with the spoon.
  3. Dip the cotton bud into the mixture and write a message onto the white paper.
  4. Wait for the juice to dry so it becomes completely invisible.
  5. When you are ready to read your secret message or show it to someone else, heat the paper by holding it close to a light bulb.

Grow a Bean in a Jar– From Science-Sparks

  • A broad bean seed
  • Jar
  • Kitchen roll or a napkin
  • Water
  • Swirl a small amount of water around the jar.
  • Fold your napkin or kitchen roll and place in the jar. ( we made the kitchen roll very slightly damp also )
  • Place the bean seed in the jar resting on the napkin.
  • Spray some water on the bean every few days.

The bean should start to grow roots after a few days

Pepper and Soap Experiment-Education.com

  • Shallow bowl or pie tin
  • Water
  • Pepper
  • Dish soap
  • Toothpick
  • Paper
  • Pencil
  1. Fill the bowl or pie tin with about an inch of water.
  2. Sprinkle pepper evenly across the surface. The pepper flakes should float, not sink, upon the surface of the water.
  3. Squeeze a tiny bubble of dish soap onto a clean counter.
  4. Touch the tip of the toothpick to the bubble of dish soap. You’ll want just a tiny amount of soap on the end of the toothpick.
  5. What happens? Talk about it with a parent!
