Our egg containers

As part of our Inquiry unit we have been doing in room 3 we explored how egg cartons are made, what attributes they have and how people carried eggs in the past.
We had to work together in groups to design and make a container that would hold one raw egg and keep it intact when the container was dropped from a one metre height.
We then tested our containers by dropping them from first 1.5 metres and then 2.1 metres for those that were still intact. We recorded the results and decided what we would change if we were to make it again.

To make our design better we should put more foam on the top of the egg. It was a success when we dropped it from 1.5m but when we dropped it from 2.1m it cracked because when you dropped it from a few more metres it goes further it also bounced up. I liked watching the other group`s emotions when they dropped the container. I found out the egg breaks easily when you dropped it from a certain height. I also found out the egg containers are made out of paper mache.

Our egg stayed whole when it was dropped from 1.5 metres. When the container was dropped from 2.1 metres it cracked. It cracked because the container wasn’t strong enough.
If we made another container we would make ours smaller. We would put cotton balls around the egg. We would make a little box shape.
I learnt that egg cartons are light so people can carry them. The part I liked best was dropping our egg container.
