Experiment #2 Surface Tension
This activity explores surface tension. Surface tension
is an attractive property of the surface of a liquid. It is what causes
the surface portion of liquid to be attracted to another surface, such
as that of another portion of liquid.
Experiment #3 Forces
This
activity explores Newton's 3rd law that states every force has an equal
and opposite force. In this experiment we can explore what the opposite
force would be, based on what direction the air is released from a
balloon.
Experiment #4 Density
This experiment confirms what you already know, molecules
of oil and and molecules of water do not mix. It very simply
demonstrates the concept of density for different liquids.
Experiment #5 Food
Science
Our own
kitchens provide a perfect setting in which to explore a variety of
scientific activities. Making homemade ice cream is a wonderful
opportunity to learn about how liquids can take on the properties of a
solid, or the phase change of matter.
Experiment #6
Borax Snowflakes
Are you
looking for a fun and educational science project your whole family can
participate in during the holidays? Then growing borax snowflakes is for
you. With a little “household science,” you can create long-lasting
crystal snowflakes that are just as sparkling as the real ones.
Experiment #7 CD Spectoscope
Explore the light and
colors of our world by making your own Spectroscope.
Scientists use special
instruments that help them understand the universe, galaxies, stars, and
planets. An important tool used to gather information about these
objects is called a spectroscope.
Experiment #8 Electromagnets
Have you ever used a magnet to pick up paperclips or made the dial of a compass spin or seen how one end of a magnet attracts an end of another magnet, but repels the other? You might be surprised to find that magnets and electromagnets are used all around us since every electric motor, generator or transformer requires a magnetic field for its operation.
Experiment #9 Centripetal Force
Did you watch the last winter Olympics? When ice skaters spin, they demonstrate centripetal force – the law that says that an object moving in a circle undergoes acceleration toward the center of the circle. And this experiment can also demonstrate that in your very own home!
