Smashing Eggs Experiment

We've been learning about eggs and have done a couple of experiments.

Today's was the most exciting because I goofed and broken eggs were everywhere!!  You should have heard the screaming. Hee hee.

First we talked about how fragile eggs are.

Then we predicted how many small white boards 3 eggs could support before breaking.

The kids' predictions ranged from two to 50.

After some trial and error, we finally got everything set up. Those are glue caps. We needed to use them because we had several tries where the eggs were supported with play dough. But that didn't work because the boards just kept sliding off. 


The kids were VERY surprised to see that the eggs could support all the white boards AND all the bigger heavier chalkboards we have!  So was I.

So we kept going and started adding our Dr. Seuss books. The eggs STILL didn't break, so we put on two bins of exercise books (I forgot to take a picture of that).


The second bin of books sat proudly on top of the pile for about 5 seconds and then CRASH!  It all came down.


Now sadly, I don't have a picture of the broken egg mess. Sorry. But I had one of my students taking the last pic and he was so focussed on trying to capture the actual fall that he (and I) forgot to take a picture of the raw egg that was strewn ALL across the carpet.

Yes, I'm a bit of an idiot:)  We had boards and paper towel protecting the carpet but it didn't even occur to me that the eggs would go flying off to the side as they broke.

Hence, the screams! Lots of fun in Grade 1 today.

Here's a short video that shows how it should be done properly. I think we had more fun though.

  3. I forgot to do that one this year. It's even amazing to me how fragile and strong something can be at the same time! Looks like something they will definitely remember!
