What do a glass of milk, a sponge in the sink, and a refrigerator have in common? They're alive with bacteria, mold, and kitchen chemistry possibilities.
Chemistry experiments using food you can do with kids in your homeschool kitchen.
Aidan's Freckle Juice project
Buy Freckle Juice by Judy Bloom
One day after school, Andrew works up enough courage to ask Nicky where he got his freckles. When know-it-all Sharon overhears, she offers Andrew her secret freckle juice recipe -- for fifty cents.
101 for Pound Cakes
In order for a cake to rise, it must have a leavening agent to
make the batter increase in volume. Most of the cakes use carbon
dioxide, which is released from the baking soda or baking powder
in the recipe.
Color Changing Milk
It's an explosion of color! Some very unusual things happen when you mix a little milk, food coloring, and a drop of liquid soap. Use this experiment to amaze your friends and uncover the scientific secrets of soap.
How to Churn Butter
The solid and semi-solid butter-fat globules stick together. Continued shaking results in the disappearance of the bubbles and larger masses of butter are seen. From Janice VanCleave.
Spud Guns Work
It's all about expansion of gases. In this article, we will examine
the science behind spud guns' ability to fire potatoes over long
distances. We will also discuss other uses for spud guns as well
as safety and legal issues.
Lemon Chemistry: An Acid-Base Experiment
A dramatic acid-base reaction using lemons, baking soda, and a little dish soap. Safe for pre-schoolers, and a good demo for older kids who are studying acids and bases.
Make a battery from a lemon. The lemon battery is called a voltaic battery, which changes chemical energy into electrical energy.
In chemistry, many substances change color due to reactions with
other substances. An example of this is iodine. Iodine turns
blue whenever it is combined with starch.
The magician taps the edge of a glass of water with a wand and
quickly pours it into an empty wine glass, and voila! The water
is instantly changed into red wine. Pouring the wine into a third
container changes it back into water.
For students, DIY hobbyists, and science buffs, who can no longer get real chemistry sets, this one-of-a-kind guide explains how to set up and use a home chemistry lab, with step-by-step instructions for conducting experiments in basic chemistry.
Recommended by Heidi on our Group. "It's a great book
for homeschoolers. It goes into the chemistry of foods--why they
taste the way they do, covers thermodynamics as related to cooking
and a bit of physics. There are SCIENCE/cooking experiments at
the end of most chapters, some recipes to test out the things
