5 Easy Science Experiments with Household Items


Children excited over a science experiment


Here are some simple science experiments that can be done at home with common household items:


  1. Making a Homemade Lava Lamp: Fill a glass with water and add a few drops of food coloring. Pour some oil into the glass. The oil will float on top of the water. Drop a fizzing tablet into the glass and watch your homemade lava lamp come to life!

  2. Creating Invisible Ink with Lemon Juice: Write a message on a piece of paper with a cotton swab dipped in lemon juice. Allow the juice to dry. To read the secret message, hold the paper over a heat source like a light bulb or a warm oven. The heat will cause the lemon juice to darken and reveal the message.

  3. Building a Paper Airplane Launcher: Build a simple catapult using popsicle sticks and rubber bands. Use it to launch paper airplanes and see how different designs fly differently.

  4. Growing Crystals: Dissolve table salt or sugar in boiling water until no more can dissolve. Hang a string or pipe cleaner in the solution and leave it undisturbed for a few days. Crystals will form on the string or pipe cleaner.

  5. Density Experiment: Fill a glass with layers of different liquids – honey, dish soap, water, and oil. Discuss why some liquids float on others (it's because they have different densities).

Remember, always supervise children when they're conducting experiments to ensure safety. Happy experimenting!
