Chapter One is on Beam Bridges.
HAH! Easy enough to experiment with these! And besides...the book clearly lays out the experiments one can do.
We started with Page 7, build a beam bridge. All we needed was two bricks, paper (used cardstock) and plasticine (or some other such modelling clay).
easy enough...set up your bricks. Place a piece of cardstock over it. How many plasticine bricks will it hold? We learned it ALL depends on where you place them. Smack dab in the middle...Three MAX. BUT if you put some on either end before you put them in the middle it will hold more. SEE .....
We made a waffle bridge... and WOW!! that just amazed us. We put ALL the plasticine we had on top and it didn't break! One end crumpled a bit but that we think, was due to mommy's poor folding job at that end.
So we tested out different types of columns. Square, Triangle and Rectangle
we added more.
the triangle really started to quiver and shake
we managed to get one more book on top
and then the square one gave one unfortunately falling
into the circle one.
I had no answer for him....do any of you???
