We have been learning about the physical properties of objects (buoyancy, texture, flexibility, hardness, weight, magnetic). Students were given 6 objects (Styrofoam cup, lead sinker, straw, desk, nail, and sandpaper). They had to first make predictions about the objects, then tested to see if their predictions were right. Did you know that a lead sinker is not magnetic? Did you know sandpaper will sink after about a minute? Those were the big two surprises for the class.
