Chemistry doesn’t have to be intimidating. Whether you are a high school student (10th or 12th grade) or just starting your chemistry journey, hands-on experiments make learning fun and memorable.
In this guide, we’ll explore 10 easy chemistry experiments for beginners that you can safely perform at home or in a school lab.

1. Baking Soda & Vinegar Volcano (Acid-Base Reaction)
Materials Needed:
- Baking soda
- Vinegar
- A small container (or plastic bottle)
- Dish soap (optional, for extra foam)
- Food coloring (optional)
Steps:
1. Place the container on a tray to avoid a mess.
2. Add 2-3 tablespoons of baking soda.
3. Pour vinegar slowly and watch the eruption!
Why It Works: The reaction produces CO₂ gas, creating bubbles and foam.
2. Magic Milk Experiment (Surface Tension & Chemical Reactions)
What You’ll Learn: How detergents break down fat molecules in milk.
Materials Needed:
- Whole milk
- Food coloring
- Dish soap
- Cotton swab
Steps:
1. Pour milk into a shallow dish.
2. Add drops of different food coloring.
3. Dip a cotton swab in dish soap and touch the milk surface.
4. Watch the colors burst and swirl!
Why It Works: Soap molecules disrupt milk’s fat, causing movement.
3. DIY Lava Lamp (Density & Polarity)
What You’ll Learn: How oil and water don’t mix due to differences in density and polarity.
Materials Needed:
- Clear plastic bottle
- Water
- Vegetable oil
- Food coloring
- Alka-Seltzer tablet
Steps:
1. Fill the bottle ¼ with water, then ¾ with oil.
2. Add food coloring (it will sink through the oil).
3. Drop in an Alka-Seltzer tablet and watch the "lava" bubbles form!
Why It Works: The tablet releases CO₂, creating gas bubbles that rise and fall.
4. Invisible Ink with Lemon Juice (Oxidation Reaction)
Materials Needed:
- Lemon juice
- Water
- Cotton swab
- White paper
- Heat source (lamp or iron)
Steps:
1. Mix lemon juice with a little water.
2. Use a cotton swab to write a secret message.
3. Let it dry, then heat the paper to reveal the
message!
Why It Works: Lemon juice oxidizes faster than paper when heated, turning brown.
5. Sugar Crystal Rock Candy (Crystallization)
What You’ll Learn: How supersaturated solutions form crystals.
Materials Needed:
- Sugar
- Water
- String or stick
- Glass jar
Steps:
1. Dissolve sugar in hot water until no more dissolves.
2. Pour into a jar and hang a string inside.
3. Wait a few days crystals will grow!
Why It Works: As water evaporates, sugar molecules form crystals on the string.
6. Elephant Toothpaste (Exothermic Reaction)
Materials Needed:
- Hydrogen peroxide (6% or 3%)
- Dry yeast
- Dish soap
- Food coloring
- Bottle
Steps
1. Mix hydrogen peroxide, soap, and food coloring in a
bottle.
2. In a separate cup, mix yeast with warm water.
3. Pour the yeast mixture into the bottle and watch the foam explode!
Why It Works: Yeast acts as a catalyst, breaking H₂O₂ into water and oxygen gas.
7. Red Cabbage pH Indicator (Acids & Bases)
Materials Needed:
- Red cabbage
- Hot water
- Test liquids (vinegar, baking soda solution, lemon juice)
Steps:
1. Boil chopped cabbage to extract purple liquid.
2. Strain and let it cool.
3. Add different liquids, watch colors change (red = acid, green = base).
Why It Works: Anthocyanin pigments change color based on pH.
8. Fireproof Balloon (Heat Conductivity)
What You’ll Learn: Why water absorbs heat, preventing the balloon from popping.
Materials Needed:
- Balloon
- Water
- Candle
Steps:
1. Fill a balloon with some water.
2. Hold it over a flame, it won’t burst!
Why It Works: Water absorbs heat, keeping the rubber cool.
9. Dancing Raisins (Density & Gas Bubbles)
Materials Needed:
- Clear soda (e.g., Sprite)
- Raisins
- Glass
Steps:
1. Drop raisins into soda.
2. Watch them "dance" up and down!
Why It Works: CO₂ bubbles lift raisins; when bubbles pop, they sink.
10. DIY Slime (Polymer Science)
What You’ll Learn: How cross-linking creates polymers (non-Newtonian fluids).
Materials Needed:
- White glue
- Borax solution
- Water
- Food coloring
Steps:
1. Mix glue with water and food coloring.
2. Add borax solution slowly until slime forms.
Why It Works: Borax links glue molecules, creating a stretchy polymer.
