The sixth grade is studying the properties of matter. The phases – solid, liquid, gas and plasma along with the physical and chemical properties of substances, are being contemplated. We made no bake cookies and a smoke bomb. We made the smoke bomb because Sonny, a student, has been talking about this for a long, long time!!! Sugar is a main ingredient for both recipes and as the students stirred their concoctions over the hot plate our vocabulary, and the science to go along with, were discussed. Melting point, boiling point, the addition of energy as heat was added – endothermic, as the cookies and “bomb” cooled – exothermic, all came into play. On days like this I wonder why everyone doesn’t want to be a science teacher when the learning is big, the kids are engaged and you get to light off smoke bombs! Here is a video of the smoke bomb and Sonny discussing it….
