Guest Post: Easy Science Activities for the Kitchen

by Jill & Cathy on May 28, 2014

This post is brought to you by guest blogger, Corinne Jacob from Alternate Tutelage.  Thanks so much for sharing with us, Corinne!

I am Corinne Jacob, trying so hard for my a.k.a. to be something spectacular like Supermom or Oh Captain my Captain. In reality and in no particular order, I am a writer, a content developer, a mother, a wannabe blog god and a self proclaimed geek.

I love all things that scream out unschooling, alternative education and holistic learning. I often scour the internet looking for education trends, unique ways to teach and learn, alternative parenting, DIYs and my soul is under lease to Pinterest (don’t pretend like yours isn’t!).  I believe that learning should be an enjoyable experience and in my quest to do so, I have created this platform where I can share my thoughts, things I find interesting on the internet and my ramblings on various topics.


4 Easy Science Activities in the Kitchen

Cooking with kids can be a wonderful bonding opportunity for families. Your child’s experiences with food can also help him learn many things that you’d think only belonged to a science lab. Here’s your chance to teach him about nutrition, food safety, food-related behavior and help him build his science vocabulary. Try these 4 simple kitchen science activities and experiments for kids.

  1. 1.      Invisible lemon juice painting

You will need:

  • Lemon juice
  • Paintbrush
  • Iron
  • Paper
  • Towel or ironing board


  • Squeeze lemon juice in a bowl.
  • Dip the paintbrush into the juice and create your painting.
  • Let the paper dry completely.
  • Place the paper on the towel or ironing board and heat it with the iron.

Caution – Holding the iron too long to the paper could burn it.

Science takeaway – The acid in lemon juice have weakened the paper. When you heat it, the acid will burn and turn brown more quickly than the paper.


  1. 2.      Colorful white flowers

You will need:

  • White flowers with stems (lily-of-the-valley, white carnation, etc.)
  • Food coloring
  • Glass jars
  • Water


  • Pour some water into each jar.
  • Add a few drops of food coloring to each.
  • Put one flower into each jar.
  • Leave it overnight for best results.

Science takeaway – This science activity shows how water and nutrients absorbed by plants passes onto the flowers through the stems.

  1. 3.      Growing gummy bears

You will need:

  • Gummy bears (1 of each brand)
  • Plain water
  • See-through containers


  • Record the length and mass of each gummy bear you use for the experiment.
  • Pour about 50 ml. water into each container.
  • Leave it overnight.
  • Record the length and mass of the gummy bears the next day.
  • Which brand of gummy bears grew the most?

Caution – Do not eat the gummy bears as they will be full of bacteria.

Science takeaway – Gummy bears consist of a mixture of sugar, gelatin, glucose syrup, citric acid, starch, fruit flavoring and food coloring. The mixture is poured into bear-shaped molds and dried for a few days. When you place a gummy bear in water, you are re-hydrating the gelatin and other ingredients. This allows the bear to expand.

  1. 4.      Make fizzy water

You will need:

  • Lemons
  • Baking soda
  • Sugar
  • Water
  • Ice cubes
  • Glass
  • Kitchen knife


  • Squeeze the lemons and pour the juice into the glass.
  • Add half a teaspoon of baking soda to the juice. Note what happens.
  • Add water and sugar to taste.
  • Your lemony fizzy iced water is ready!

Science takeaway – Lemon juice is an acid. You can get a chemical reaction (bubbles) when you combine it with a base like baking soda.

If you’ve got any interesting kitchen science activities of your own, I would definitely like to hear from you!
