Simple Science Experiments to Do at Home with Children

Science doesn’t have to wait until school — in fact, some of the best learning happens right at home through play and exploration. With just a few common household items, you can turn your kitchen or living room into a mini science lab! These simple experiments are perfect for young children and offer hands-on ways to build curiosity, reasoning, and observation skills.

Let’s dive into fun activities that make science exciting and accessible!

Why Do Science Experiments at Home?

  • Builds curiosity: Kids naturally ask “why?” — experiments help answer that
  • Develops problem-solving skills: Testing, observing, and learning through trial and error
  • Encourages critical thinking: Making predictions and drawing conclusions
  • Strengthens parent-child connection: Shared discovery moments are memorable and fun
  • Teaches patience and focus: Some experiments require steps and waiting

All of these benefits come while your child is simply having fun!

Safety First

Before starting:

  • Always supervise young children
  • Use non-toxic, age-appropriate materials
  • Keep experiments away from electronics or open flames
  • Have cleaning supplies nearby

Now let’s explore some amazing science in action!

1. Volcano Eruption (Baking Soda + Vinegar)

What You Need:

  • Baking soda
  • Vinegar
  • Dish soap
  • Food coloring (optional)
  • A plastic cup or small container

How to Do It:

  1. Place the container on a tray.
  2. Fill it halfway with baking soda.
  3. Add a drop of dish soap and food coloring.
  4. Pour vinegar and watch it erupt!

What It Teaches: Chemical reactions, gas formation

2. Rainbow in a Jar

What You Need:

  • Sugar
  • Water
  • Food coloring
  • 4–5 clear cups
  • A syringe or spoon

How to Do It:

  1. Mix different amounts of sugar in each colored water cup (more sugar = heavier liquid).
  2. Carefully layer them into one jar from most sugary to least.

What It Teaches: Density and layering of liquids

3. Dancing Raisins

What You Need:

  • A clear glass
  • Sparkling water or club soda
  • Raisins

How to Do It:

  1. Fill the glass with sparkling water.
  2. Drop in a few raisins.
  3. Watch them rise and fall!

What It Teaches: Gas bubbles, buoyancy

4. Magic Milk Experiment

What You Need:

  • Whole milk
  • Dish soap
  • Food coloring
  • A shallow plate

How to Do It:

  1. Pour milk into the plate.
  2. Add a few drops of food coloring.
  3. Dip a cotton swab in dish soap and touch the milk.
  4. Watch the colors swirl!

What It Teaches: Surface tension

5. Balloon Blow-Up Without Air

What You Need:

  • Balloon
  • Bottle
  • Baking soda
  • Vinegar
  • Funnel

How to Do It:

  1. Pour vinegar into the bottle.
  2. Put baking soda inside the balloon using a funnel.
  3. Attach the balloon to the top of the bottle.
  4. Lift the balloon so the baking soda falls into the vinegar — it inflates!

What It Teaches: Chemical reaction creating gas

6. Walking Water

What You Need:

  • 3 clear cups
  • Water
  • Food coloring (2 different colors)
  • Paper towels

How to Do It:

  1. Fill the 1st and 3rd cups with colored water.
  2. Leave the middle one empty.
  3. Roll paper towels and place them between each cup.
  4. Watch as water “walks” into the empty cup and blends colors!

What It Teaches: Capillary action and color mixing

7. Floating or Sinking Test

What You Need:

  • A large bowl of water
  • Small household objects (coin, sponge, crayon, paperclip, etc.)

How to Do It:

  1. Let your child guess which items will float or sink.
  2. Drop them in one by one and observe.

What It Teaches: Buoyancy and prediction

8. Make Your Own Slime

What You Need:

  • White glue
  • Baking soda
  • Contact lens solution

How to Do It:

  1. Mix glue with a pinch of baking soda.
  2. Slowly add contact lens solution until the slime forms.

What It Teaches: Chemistry, material changes

9. Homemade Lava Lamp

What You Need:

  • Clear bottle
  • Oil
  • Water
  • Food coloring
  • Alka-Seltzer tablet

How to Do It:

  1. Fill the bottle ¾ with oil, then add water.
  2. Add food coloring.
  3. Drop in the tablet and enjoy the bubbly effect!

What It Teaches: Liquid density, chemical reactions

10. Growing a Bean in a Bag

What You Need:

  • Dried bean
  • Paper towel
  • Water
  • Ziplock bag
  • Tape

How to Do It:

  1. Wet the paper towel and fold it inside the bag.
  2. Place the bean against the bag wall.
  3. Seal and tape to a window with sunlight.
  4. Observe the sprouting process over days.

What It Teaches: Plant life cycle and observation

Tips to Make Science Fun and Meaningful

  • Ask your child to guess what will happen before starting
  • Talk about why things happened afterward
  • Use simple words for complex ideas
  • Take photos to document the process
  • Make a “Science Day” each week to build anticipation

Making Big Discoveries from Small Experiments

You don’t need fancy lab equipment or complex theories to spark a love for science. With just curiosity and a few household items, your child can begin to understand how the world works. These fun, hands-on experiments provide powerful learning — and unforgettable moments shared between parent and child.
