Cake Making Science Experiment

Here is a fun activity for children of all ages. The earlier that you can get your child looking at the world around them and making observations the better. What can be more fun for a child than being able to make observations of cakes?!? This activity will help you child learn about chemical reactions.

What You Need

  • 3 small bowls
  • Several sheets of aluminum foil
  • Pie pan
  • Cooking oil
  • Measuring spoons
  • Ingredients for one cake: (You’ll need to measure and mix this set of ingredients four times with the exceptions that are given below.)
    • 6 tablespoons flour
    • 3 tablespoons sugar
    • 1 pinch of salt
    • 2 or 3 pinches of baking powder
    • 2 tablespoons milk
    • 2 tablespoons cooking oil
    • 1/4 teaspoon vanilla
    • Part of an egg (Break egg into a cup; beat until mixed. Use 1/3 of it. Save the rest for 2 of the other cakes.)

The Naked Egg

Never-mind the science, this activity is loads of fun for kids and for parents, too! This demonstration has you take the shell off an egg without breaking it! It’s amazingly simple to do…

Materials:

  • Raw Egg
  • Cup
  • Vinegar

Procedure:

Fill a cup with vinegar, and carefully put a raw egg inside. Keep an eye on it for 3 days. On the third day, the shell should be completely gone, and there should be a bouncy ball of egg in the cup!

Explain that the membrane that is left is a lot like the one in a mommy’s tummy when she has a baby inside. Just like the egg membrane protects the chick inside the egg, the sac in a mother protects the baby inside her.

This membrane is actually very strong, and you can bounce it like a ball, although we do not recommend dropping it from too high!

Chemical Reaction Experiments – Baking Soda and Vinegar

vinegar and baking soda experimentThe combination of baking soda and vinegar is the perfect experiment for the preschool classroom. It is a safe chemical combination that is very attention grabbing.

Lesson objective:
The children will understand that some things in our world work in a predictable way. They will learn that mixing baking soda and vinegar will always have the same result.

In these three experiments your children will observe the chemical reaction of baking soda and vinegar and predict an outcome.

Play and Experiment – The Introduction

Bake It!

breadThis baking soda and vinegar science experiment will allow the children to see how science is used every day. It is a tasty chemical reaction will increase the children’s understanding of this topic.

Vocabulary:

Chemical reaction
Baking soda
Vinegar
Mix
Bubbles

Materials/Ingredients:

Bowl, cup, mixing spoons, round baking pan (greased)

1 cup milk
1 teaspoon vinegar
2 cups flour
½ teaspoon salt
½ teaspoon baking soda

Making Irish Soda Bread

Procedure:
1. In this experiment you are going to make Irish Soda Bread with the children.Before you start baking, show them the ingredients.

Question to ask:

  • Why do you think there is baking soda and vinegar in this recipe?
  • What effect will these two ingredients have on the bread?

2.Start baking process

  • Preheat oven to 400 degrees.
  • Mix milk and vinegar in cup and set aside for about 10 minutes. This will curdle the milk.
  • In the bowl, stir together the flour, salt and baking soda.
  • Stir the milk mixture into the flour mixture until smooth.
  • Scrape the dough out of the bowl onto a floured surface.
  • Form dough into disk shape and put into pan.
  • Bake for approximately 15 minutes.

3. When the bread is baked and cooled slice a piece for each child.

Have the children observe the air pockets in the bread. Discuss that, just like in their previous experiments, the mixing of the baking soda and vinegar created bubbles.he bubbles in the bread just happened to become stuck in the dough.

Note: This is the final activity in a series of experiments on the chemical reaction of baking soda and vinegar. This series begins here: Baking Soda and Vinegar Science Unit
