I have working models of all the different bridge types, which the kids can use to understand the engineering forces at work.

Also the many cranes can teach the kids :

-about leverage, pulleys and Mechanical Advantage

– what the max load is- and how much counter weight is needed

If possible- we could go outside to the school playground???? and use trigonometry to do “surveying”.

Each kid could build either:

-this truss bridge ($8) per

Or this bridge

\

for around $20 per

OR

this crane

also around $20 per
