Science Fair Success Using Supermarket Products
(Science Fair Success)
by Salvatore Tocci
Students are told how to turn milk into cheese, test the sugar
content of cookies, and encouraged to try other intriguing activities.
Explains scientific concepts such as viscosity by experimenting
with honey (Egypt) or how osmosis works by soaking cucumbers
in vinegar (France).
Food Chemistry
Chemistry experiments using food you can do with kids in your homeschool kitchen.
Cabbage
Juice - pH indicator
Make your own acid/base indicator by boiling red cabbage. Use
the juice to pH-test different fluids.
Chemistry
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.
A
Chocolate Chip Cookie Recipe for Chemists
The following recipe for chocolate chip cookies appeared in Chemical
& Engineering News (June 19, 1995). It was attributed to
Jeannene Ackerman. Enjoy!
Homemade Glue from Milk
With this experiment you can make surprisingly good glue from common kitchen items.
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.
How
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.
Making
Invisible Ink Appear
Using milk, baking soda, lemon juice or other food sources to
make invisible ink. Which works best?
Testing
for Starch
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.
Twinkies Test
This is a series of experiments done during finals week by a
bunch of Rice U. students. A humorous look at experiments to
reward you for sticking with me this far.
Water
to Wine
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.
The secret to giving your kids a really great homeschool science education...even if you don't know much science yourself, or don't have the time to teach it.
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
learned."
