Physical Changes

Earlier this week, we looked at physical changes. I modeled a physical change by ripping, tearing, cutting, and crumbling paper. We read and then determined that a physical change is when 1 or more properties change, but it does not change into a new type of matter. We came up with some examples: melting, evaporating, condensation, freezing (which are all affected by temperature), cutting, tearing, ripping, crushing, and twisting.

The investigation we did was we put a piece of ice into a bag (actually we did this three times) and then placed 1 bag into hot water, cold water, and then room temperature water. Students recorded the temperature of each water and then observed. Students determined that the hot water caused the ice cube to melt the fastest. They are becoming quite the little scientists!!
