FORCES!

Today we learnt about forces with marshmallows!  I had the kids draw a grid pattern on the marshmallows, apply external forces (tension, compression, bending, ripping/sliding, and torsion) and record their results.  The worksheet is available for download here but only en Français

See background notes here

We will also be doing a virtual lab where they will fill our THIS DOCUMENT using the Building Big website.  It is an excellent demonstration of fores, materials, load, and shape of structures.
