Collect 4 cups Fill them with water Put the metal objects inside the cups Place the cups in their positions (outside, heated in the microwave, the freezer and in the room.) Each day watch for changes

The hot cup produced the most rust over 2 days. The room temperature came in second place. The warm cup (from outside) made the third most rust. The cold produced the least amount. They all made rust after 2 days.



CONCLUSION It doesn't matter the temperature because it all makes rust and we know when each day they are making changes.
