5 Quick and Easy Lemon Science Experiments

When life gives you lemons, make science! Teach your little scientist the basics of acidity, have fun with fizzy chemical reactions, reveal hidden messages, or turn a lemon into a battery with this list of quick, easy lemon experiments.

  • Visual aid of how to complete Color Changing Lemonade

    Make chemistry you can taste with this refreshing color changing drink!

  • Visual aid of how to complete Lemon Battery
    Lemon Battery

    (Ages 5-11)

    The potato battery is a classic but did you know that you can also make a battery out of a penny and lemon? In fact, there are a bunch of household items that can be made into batteries! In this project, we test a penny and lemon to see how many volts it can produce!

  • Visual aid of how to complete Invisible Ink with Lemon Juice

    Write secret messages to your friends and family and then let them decode it with any source of heat - like a candle or an incandescent light bulb!

  • Visual aid of how to complete Apple Oxidation Experiment

    Have you ever noticed that if you slice an apple in the morning, it turns brown by lunch? This is actually a chemical reaction at work! In this experiment, you’ll learn more about how the oxygen in the air around us causes this reaction (also known as oxidation). With a little help from Ziploc® brand bags, test different liquids to see if you can figure out a way to keep apples fresh from morning to noon.

  • Visual aid of how to complete Cabbage Chemistry

    Color your world with cabbage and learn about chemistry! The terms acid and base describe chemical properties of many things we use everyday. An acid is a substance that donates hydrogen ions, and a baseis a substance that accepts hydrogen ions. Sometimes, you can tell if something is an acid or base by the way it tastes. Acids, like vinegar, are generally sour. Bases generally taste bitter. (But heads up —some acids and bases are dangerous, so we don’t recommend tasting unknown substances!) Instead of a taste test, chemists use a pH scale to measure the strength of acids and bases. The lower the number on the pH scale, the more acidic something is. In this project, you’ll test different substances in purple cabbage juice and compare the results to a printable pH scale.
