Easy Science Experiments Using Household Items

Easy Science Experiments Using Household Items

There’s nothing quite like watching your child’s eyes light up as they mix two simple ingredients and see something magical happen. That’s the wonder of science—it transforms the ordinary into the extraordinary. And the best part? You don’t need a fancy lab or expensive equipment to bring science to life in your homeschool.

At The Homeschool Wiz, we believe that learning should be fun, hands-on, and accessible. That’s why today, we’re diving into Easy Science Experiments Using Household Items—a collection of creative, safe, and educational experiments you can do right at your kitchen table.

These experiments cover a range of scientific principles, from chemistry and physics to biology and earth science. They’re perfect for all ages and great for building curiosity, confidence, and critical thinking skills. So, grab your supplies and let’s get experimenting!

1. Dancing Raisins

Scientific Concept: Density and buoyancy

Supplies Needed:

  • Clear soda (like Sprite or 7-Up)

  • A tall, clear glass

  • A handful of raisins

Instructions:

  1. Fill the glass with the clear soda.

  2. Drop in 5–7 raisins.

  3. Watch closely as the raisins begin to "dance" up and down!

What’s Happening:
The carbon dioxide bubbles attach to the rough surface of the raisins, lifting them up. When the bubbles pop at the surface, the raisins sink again. It’s a simple and fun way to demonstrate buoyancy and gas release.

2. Magic Milk Explosion

Scientific Concept: Surface tension and chemical reactions

Supplies Needed:

  • A shallow dish or plate

  • Whole milk (or 2%)

  • Food coloring (variety of colors)

  • Dish soap

  • Cotton swabs

Instructions:

  1. Pour milk into the dish, just enough to cover the bottom.

  2. Add several drops of different food coloring in the center.

  3. Dip a cotton swab into dish soap, then touch the center of the milk.

What’s Happening:
The soap breaks the surface tension of the milk and causes the fat molecules to move, creating a swirling, colorful explosion!

3. Homemade Lava Lamp

Scientific Concept: Density and chemical reaction

Supplies Needed:

  • A clear bottle or jar

  • Vegetable oil

  • Water

  • Food coloring

  • Alka-Seltzer tablet

Instructions:

  1. Fill the bottle ¾ full with oil.

  2. Add water until the bottle is nearly full.

  3. Add a few drops of food coloring.

  4. Drop in half an Alka-Seltzer tablet and watch!

What’s Happening:
Water is denser than oil and sinks to the bottom. The Alka-Seltzer reacts with water to release gas bubbles, which carry some colored water upward. When the bubbles pop, the water sinks again—just like a lava lamp!

4. Invisible Ink with Lemon Juice

Scientific Concept: Oxidation and heat reactions

Supplies Needed:

  • Lemon juice

  • Cotton swab or small paintbrush

  • White paper

  • A lamp or iron (adult supervision required)

Instructions:

  1. Dip the swab or brush into lemon juice and write a message on the paper.

  2. Let it dry completely.

  3. Hold the paper near a heat source or iron it gently.

What’s Happening:
Lemon juice weakens the paper fibers and oxidizes when heated, turning brown. This reveals the hidden message!

5. Baking Soda Volcano

Scientific Concept: Acid-base reaction

Supplies Needed:

  • Baking soda

  • Vinegar

  • Dish soap (optional)

  • Food coloring

  • A container (plastic cup or small bottle)

  • Tray or dish to catch overflow

Instructions:

  1. Place the container on the tray.

  2. Add 2–3 tablespoons of baking soda into the container.

  3. Add a few drops of dish soap and food coloring.

  4. Pour in vinegar and watch the eruption!

What’s Happening:
The vinegar (acid) reacts with baking soda (base) to release carbon dioxide, causing a bubbly, foamy eruption. Adding dish soap enhances the fizzing effect.

6. Walking Water

Scientific Concept: Capillary action

Supplies Needed:

  • 3 clear cups

  • Water

  • Food coloring

  • Paper towels

Instructions:

  1. Fill two outer cups with water and add food coloring (e.g., red and blue).

  2. Leave the middle cup empty.

  3. Fold two paper towels into strips and place one end in the colored cups and the other in the empty cup.

  4. Wait and observe over an hour or more.

What’s Happening:
Water travels up the paper towels and into the empty cup, eventually mixing to form a new color. It’s a perfect demo of how plants absorb water through their roots.

7. Egg in Vinegar (Rubber Egg)

Scientific Concept: Acid dissolving calcium carbonate

Supplies Needed:

  • Raw egg

  • Vinegar

  • Jar or cup

Instructions:

  1. Place the egg in a jar and cover it with vinegar.

  2. Let it sit for 24–48 hours, checking occasionally.

  3. Remove and gently rinse the egg.

What’s Happening:
The vinegar (acetic acid) reacts with the calcium carbonate shell, dissolving it and leaving behind the semi-permeable membrane. You’ll be left with a rubbery, bouncy egg!

8. Balloon Blow-Up Without Blowing

Scientific Concept: Gas production in chemical reactions

Supplies Needed:

  • Balloon

  • Bottle (plastic water bottle works)

  • Baking soda

  • Vinegar

  • Funnel

Instructions:

  1. Pour vinegar into the bottle until it’s about ⅓ full.

  2. Use the funnel to add 2–3 teaspoons of baking soda into the balloon.

  3. Stretch the balloon over the bottle opening without spilling the baking soda in.

  4. Lift the balloon so the baking soda falls into the vinegar.

What’s Happening:
The baking soda and vinegar produce carbon dioxide gas, which inflates the balloon. A great way to demonstrate chemical reactions and gas expansion.

9. Static Electricity Butterfly

Scientific Concept: Static electricity

Supplies Needed:

  • Tissue paper

  • Construction paper

  • Balloon

  • Scissors

  • Tape

Instructions:

  1. Cut a butterfly shape out of tissue paper.

  2. Tape its body (middle) to a table or hard surface so the wings can flap.

  3. Blow up the balloon and rub it on your hair or a wool sweater.

  4. Slowly move the balloon near the wings.

What’s Happening:
Static electricity from the balloon causes the lightweight tissue paper wings to rise and "flutter."

10. Color-Changing pH Indicator

Scientific Concept: Acids, bases, and natural indicators

Supplies Needed:

  • Red cabbage

  • Blender or hot water

  • Strainer

  • Clear cups

  • Household liquids (lemon juice, vinegar, baking soda solution, soap water)

Instructions:

  1. Blend chopped red cabbage with water, or soak in hot water to extract the color.

  2. Strain to get a purple liquid.

  3. Pour small amounts into clear cups.

  4. Add different household liquids to each.

What’s Happening:
Red cabbage contains anthocyanins, which change color depending on pH. Acidic liquids turn it pink/red, neutral remains purple, and bases turn it green or blue. Great for a mini chemistry lab!

Science on a Budget, Magic in Every Home

The beauty of these experiments is that they turn everyday items into incredible learning opportunities. You don’t need to invest in expensive kits to create moments of wonder—just a little curiosity, some basic supplies, and a willingness to explore.

These simple experiments also open the door to deeper discussions:

  • Why did this happen?

  • Can we change a variable and try again?

  • What does this remind us of in the real world?

Encourage your children to make predictions, record observations, and draw conclusions. Even young learners can create a mini "Science Journal" to track their discoveries.

Let’s Keep the Curiosity Going!
