5 Easy Science Experiments You Can Do at Home

Children doing a science experiment at home

You do not need a lab coat or expensive equipment to do real science. Many of the best experiments for kids use household items like vinegar, paper towels, and sparkling water.

Each experiment includes materials, steps, and a plain-language explanation so you can talk about what your child observed.

1. Baking Soda and Vinegar Volcano

Chemistry

Materials

  • 1/2 cup baking soda
  • 1 cup white vinegar
  • A few drops of dish soap
  • Food coloring (optional)
  • A cup or bowl

Steps

  1. Put baking soda in the cup.
  2. Add dish soap and food coloring.
  3. Pour in vinegar and step back.
  4. Watch the foam erupt.

The Science

Baking soda and vinegar react to produce carbon dioxide gas. Dish soap traps the bubbles and makes foam.

2. Dancing Raisins

Physics

Materials

  • A clear glass
  • Sparkling water or clear soda
  • A handful of raisins

Steps

  1. Fill the glass with sparkling water.
  2. Drop in a few raisins.
  3. Watch for several minutes.

The Science

Carbon dioxide bubbles stick to the raisins, lift them up, pop at the surface, and let them sink again.

3. Homemade Lava Lamp

Chemistry & Physics

Materials

  • A clear bottle
  • Vegetable oil
  • Water
  • Alka-Seltzer tablets
  • Food coloring

Steps

  1. Fill the bottle mostly with oil.
  2. Add water and food coloring.
  3. Drop in a small tablet piece.

The Science

Oil and water do not mix. Gas bubbles carry colored water upward, then release it so it falls again.

4. Paper Towel Chromatography

Chemistry

Materials

  • Paper towel or coffee filter
  • Washable markers
  • A cup of water
  • Scissors

Steps

  1. Cut a paper strip.
  2. Draw a marker dot near the bottom.
  3. Dip only the bottom edge in water.
  4. Watch colors separate.

The Science

Ink is made of multiple pigments. Water carries them up the paper at different speeds, separating the colors.

5. The Egg in a Bottle

Physics

Materials

  • A peeled hard-boiled egg
  • A glass bottle
  • A small piece of paper
  • Matches with adult supervision

Steps

  1. Light the paper and drop it in the bottle.
  2. Place the egg on the opening.
  3. Watch the air pressure push it in.

The Science

The flame heats air inside the bottle. When it cools, pressure drops inside and outside air pressure pushes the egg through.

Making It Stick

After each experiment, ask your child to draw what happened and write one sentence about why. Explaining it to someone else turns a fun moment into real understanding.

Our workshops include experiments like these plus guided discussion that helps students understand the science behind the reactions.
