Welcome to the science is fun page!
Keep watching this page for fun activities that you can do at home.
The first activity that I would like to put on here is the slime
recipe.....
In the first bowl mix: 3/4 cup warm water, 1 cup glue, and food
coloring if you want too.
In the second bowl mix: 4 teaspoons of borax (you can get it at the
store on the laundry soap aisle, or get it from me) and 1 1/3 cups
warm water.
Mix the two mixtures together, it is ok to pour off the extra water
and keep mixing with your hands. It will stretch and break!
The second activity for our page is an ice cream lesson that we might
do later in the year!
4 eggs (beaten well)
2 cups of sugar
4 cups of half and half(found in the milk section)
2 teaspoons of vanilla
1\2 teaspoon of salt
milk
empty gallon jug
crushed ice
table salt (or rock salt)
spoons and cups
Large ziploc bag
small ziploc bag (yellow and blue make green kind work best!)
1. Mix eggs, sugar, half and half, vanilla and salt in gallon jug and
shake well. Pour milk into jug until it is almost full. put the lid
on and shake.
2. Place 1 cup of mixture in the small ziploc bag and seal tightly.
3. fill large ziploc bag 1\2 full of ice and pour 1\4 cup of salt on
top of the ice. Place the small bag inside the large bag.
4. Using your hands, mix (churn) the ice cream. You should be able
to tell when it is ready. It takes about 15 minutes(depending on how
much salt you put on the ice) more salt on ice makes it work faster.
5. Your hands will be cold, but it will be worth it!
Amazing Egg Experiment
Day one - Take one raw egg and place it in a jar carefully. Do not
crack the shell. Cover the egg with vinegar. Put the lid on the jar
and make observations. What do you see? Leave the egg for three
days and make more observations.
Answer to day one - Bubbles start forming on the surface of the egg's
shell immediately and increase in number with time. After 72 hours
the shell will be gone. The egg remains intact because of the thin
transparent membrane. The size of the egg has increased. The shell
of the egg is made of calcium carbonate, commonly called limestone.
When vinegar chemically reacts with limestone it produces carbon
dioxide gas, that's where the bubbles come from. The membrane of the
egg becomes more rubbery and could even bounce if dropped. Be
careful if you try that, it could break. The increased size comes
from the water in the vinegar moving in through the cell membrane,
this is called osmosis. You could even try putting the egg in a jar
of water and see if the egg gets any bigger.
Day three - Take the egg out of the jar carefully and rinse it.
Place three inches of corn syrup in the jar and then carefully place
the egg back in the jar. Close the lid and allow the jar to sit for
3 days. Make observations.
Answer day three - The egg will drastically change in size and
shape. It has a rubber outer skin with very little content inside.
The excess water inside the egg moves through the membrane into the
syrup. The water content outside the egg is much less that inside,
thus the water moves out of the egg. The molecules in the syrup and
other materials inside the egg do not move through the membrane
because they are too large.
Have fun and remember science is fun!
