The egg
project we did in science was to see how many journals 4
eggshells can hold. I was in a group with Olivia and
Travis. Our eggshells only held 16 journals. The class
weighed the science books and said that each science book
adds up to 5 journals. Paige, Kaylyn, and Mary had 23
journals. That was the record of the class. After the
eggshells broke we scooped them into a cup with vinegar
and let them sit over night. The next day we took them
off the counter and looked to see what happened over
night. We stuck our hands in to feel them and they were
all soggy. … Erin
What will the egg shells
look like after soaking all night in vinegar? Did you
know egg shells had calcium in them?
Did you know vinegar is a
weak acid?

 In my group there was Kaylayn, Mary
and me, Paige. We had 23 journals on our eggs. It was the
most in our class. We were putting on the 24 journal when
the eggs broke. I think we could have had a lot more.
This experiment was really really fun. I wish we could do
it again. By Paige
In science, we
did a fun experiment about the strength of eggshells. We
cracked lots of eggs in half, and each group got four
half eggshells. We put them in the shape of a square and
put as many books as we could on top of them until they
broke. One group of kids got 24 journals on the
eggshells!
After the eggshells broke, we put them in a cup with
vinegar. There were lots of bubbles, and some of the
pieces of eggshells floated to the top of the vinegar.
When we left the eggshells in the vinegar at night, the
white eggshells got soft because the vinegar dissolved
the calcium inside the shells. For some reason, the brown
eggshells didn’t get as soft as the white eggshells
did.
It was really fun and we learned stuff too! …by
