Add
joy and share the fun of scientific experimentation with friends and
family members.
Safety comes first. Be sure to follow each instruction carefully. HAVE FUN!
Our senses of smell and taste interact to form impressions of what we eat, as well as of the world around us!
Make your own music with simple household items!
Build your own colorful bead bottle to amaze your friends!
Use an indicator made from red cabbage juice to determine
whether household products are acids or bases.
Most plastics are made in factories, but here's
one you can make at home.
Use
a heavier than air gas to suspend soap bubbles. This
will allow you to more closely examine the unique
properties of bubbles .
Ever played with a Lightstick? In this activity you
examine the chemiluminescent reaction that makes a
Lightstick glow in the dark.
Use ordinary clear soda to make raisins dance. Learn
what's in soda that gives it fizz, and what causes
things that are heavier than water to float.
Will
a bowling ball sink or float in water? The answer
seems obvious, but this experiment will show otherwise.
Use
common liquids you can find around your house to make
a density column and a rainbow in a glass.
Clean the tarnish off of silverware. You don't need
expensive cleaners, just this experiment.
Some wire, a couple of magnets, and a battery –
and you can build your own electric motor.
The power of wind is harnessed in this experiment.
Suspend a balloon in air without using your hands!
In
this activity you will examine the behavior of rubber
as it is affected by heat, a form of energy.
What
makes certain materials "glow" under a black
light? This experiment will tell you why.
The
color of many candies come from dyes. This experiment
will separate some of those dyes out using a process
called chromatography.
With
just a few household chemicals you can turn a glass
of colored liquid into a froth that overflows its
container.
What
is the easiest way to pop a balloon? With a needle
of course. Is there a way to put a needle into a balloon
without popping it?
A
fire can weaken the rubber in a balloon and cause
it to burst. In this experiment you will find out
how you can hold a balloon directly in a flame without
breaking it.
Many
people have water softeners in their houses. What
is the purpose of a water softener? What does it
mean to have "hard" water?
How
much force does it take to crush an aluminum can?
Is there a way to crush a can using only air pressure?
Have
you ever turned a liquid into a solid just by tapping
on it? In this experiment you will make a liquid
that behaves in a very unpredictable way.
Next
time you're at a picnic, look at the soda cooler:
some cans float, while others sink. Do this experiment
to understand why.
Why
does the sky look red during sunrises and sunsets?
We can learn why during this experiment.
Create
a "cartesian diver" inside a 1 or 2 liter
plastic bottle. This diver will sink or float on
command!
Static electricity can be a problem whenever the humidity
is low. In this experiment you will use static electricity
to "bend" water.
Even though the egg is bigger than the opening of
the bottle, you can get the egg to go into the
bottle without touching it.
Build your own apparatus to test the
electrical conductivity of solutions!
