Super Star Scientist Emma!

Objective:  What makes a corrugated box strong?

Materials:  3 sheets of typing paper, 2 cans (lg. & sm.), tape, and scissors

Emma had all of her materials ready and was set with her lab coat and safety glasses!

First, Emma cut 2 strips of paper the width of a can and rolled one of them around the can and taped it to make a cylinder.

She did the same thing to make a 2nd cylinder. 

Next she placed the paper cylinders out in front of her,

had a little discussion with her assistant,

then placed a flat piece of typing paper over the top of the 2 cylinders.

She placed the small can on top to see if the paper could hold it.

It wasn't strong enough and fell right through!

Next, she folded the paper back and forth...

…and creased it like when making a fan. 

She then placed the folded paper on top of the cylinders.

When she placed the small can on this time,

the paper was able to hold it!

Way to go, Emma!!

Conclusion:  Emma added strength by using corrugated paper and distributing the weight better!

You were a great scientist, Emma!

What a fun experiment!!
