What You Did
You built 3D shapes with some handy kitchen items.
You can use a variety of measuring tools to test your structures: ruler, protractor, kitchen scale, microscope, magnifying glass, and mariner’s quadrant
Marshmallows are very soft. If you have trouble getting them to hold their shape, leave them out or in the refrigerator overnight to let them harden a bit, then try again
Think of other unusual items you can build with. Mix and match different kinds of toys and blocks for building
