Easy science experiments for kids provide a fun way to introduce kids to science. Sometimes a more complicated project frustrates the young ones. But an easy science experiment offers a low key activity that teaches and entertains.

This week we did three science projects: Ketchup Diver, Balloon Light Switch, and Oil and Water Color. I also introduced a new scientist, my youngest granddaughter, Shyanne. She enjoys experiments, so expect to see more videos of her in the future.

Ketchup Diver

If you are looking for an easy science experiment for kids, this is the easiest. Supplies consist of an empty 2 liter bottle, a ketchup packet, and water. Drop the ketchup packet in the bottle, fill the bottle with water and screw on the top. Squeezing the water-filled bottle (this is the hardest part) changes the density of the air bubble in the ketchup packet and causes it to sink.

The ketchup diver demonstrates changes in density and buoyancy in a very visual way. This experiment comes from one of our favorite books: The Dad Lab: 50 Awesome Science Projects for Parents and Kids by Sergei Urban.

Balloon Light Switch

Static electricity annoys me when I walk across the carpet and get shocked when I kiss my husband. But it amazes me when I can harness it to power a light bulb, even if it’s for a second. My granddaughter assisted in this experiment and her full head of blonde hair aided in generating static electricity.

We had the needed supplies on hand: balloon, fluorescent light bulb, and of course lots of hair. I inflated the balloon and rubbed it in my granddaughter’s hair for 30 seconds. Next, I held the balloon up to the bulb, which lit up. We transferred to the closet so we could see the illumination.

This experiment also came from The Dad Lab: 50 Awesome Science Projects for Parents and Kids by Sergei Urban.

The hard part of this experiment was capturing the lit bulb on camera. We could all clearly see the light bulb flicker, but it did not show up well on the video.

If you have tried this experiment, have you had success filming it? How did you get the light to show up?

Oil and Water Color

This was my favorite experiment. The final product released packets of color into the water like fireworks bursting in a dark sky.

Supplies needed: vegetable oil, water, food coloring, and two glasses.

Pour some oil into one of the glasses. Next drop generous amounts (10 drops or so) of several different food colors. Mix well. The colors will not dissolve into the oil, but mix until you see a fine suspension of color in the oil.

Next, pour the oil into a glass of water. Now comes the fun part. Watch for several minutes as the components separate. First, the oil and water form different layers. Then the colors come out of suspension in the oil and streak through the water creating ever changing lines of color.

After a few minutes, the show is over and you pour it all down the drain.
