My children are already showing a great love of Science
and I couldn't be happier. We are always trying some new
experiments! I thought maybe you would like to try some
with your children and also find some links to many other
pages about Science and Experiments!
NOTE:Kids please do these experiments with an adult!!
Steam Cone
You Need:
strip of lightweight cardboard, 3x8 inches
small container(spice jar or vitamin bottle
flat tray or pan
1/2 tablespoon quick-rising yeast
1/2 cup hydrogen peroxide
scissors
paper clip or tape
spoon
What to Do:
Wtih the cardboard strip, form a cone shape that will fit
over the mouth of the small container and fasten it with
the paper clip or tape. Cut the end corners off so the cone
will stand upright in the tray or pan. Place the small
bottle or jar in the tray and get ready for action.
The jar or bottle should be large enough to contain the
hydrogen peroxide but fit under the cardboard cone or
extend slightly above the cone's mouth. With the cone over
the small container, pour in the hydrogen persxide followed
by the quick-rising yeast. Stir the mixture thoroughly.
(If easier, you may place the cone over the bottle after
stirring, but you must be quick!) Continue to stir the
mixture, for best results, until the experiment is
finished.
What Happens:
The mixture of hydrogen peroxide and yeast causes foam,
steam and a hissing noise to come from the cardboard
"volcano".
CAUTION! Throw away all chemical solutions and thoroughly
wash out all containers when finished.
Glacier Melt
You Need:
a small cup or yogurt container
sand
small rocks or pebbles
water
freezer
piece of board, to make a slant or incline
hammer and nail
a thick rubber band
watch
What to Do:
Place a one inch layer of sand and gravel in the cup,
followed by a few inches of water. Place it in the freezer.
When frozen solid, repeat the process, adding sand, gravel,
and water, then freezing. The cup should be filled to the
top.
Next, carefully hammer a nail part way into the middle of
one end of the board. Place that end against something
immovable to form an incline or slant. Now you are ready.
Remove your model glacier from the freezer. Warm the sides
of the container under warm tap water just enough to get
your model glacier to slide down when tapped. With the
rock/sand side down, place the glacier at the top of the
incline and fasten the rubber band around its middle and
around the nail. How long will it take your glacier to
melt, move and leave rock and sand deposits? Time it.
What Happens:
Depending on the weather, melting should begin immediately,
even on cooler days. Rock and sand deposits will fall off in
clumps, some will slide down the board, while other
separate bits amd pieces will form along the board
surface in strange patterns, much like moraine or glacial
matter.
