When practicing our ability to measure, compare, and contrast objects, we began by observing a group of objects and listing out their physical properties. Physical properties are simply the observable characteristics of an object. Then the students tested to see if each object was magnetic or not. After we recorded our results, we thought about characteristics that might make an object magnetic, and if those characteristics ALWAYS make an object magnetic. For example, is an object magnetic simply because it feels like it is made of metal?
Our final discussion was led by these two questions: Does the state of matter affect whether an object sinks or floats? No, because we had solids that both sink and float and liquids that both sink and float. Does the mass affect whether an object sinks or floats? Yes, the higher masses sink, while the lower masses float.
