Chemical change


This morning my class and I were making a breakfast cup to prove that there is a chemical change using food and many utensils. We were split up into our gender type. First mrs Ramkalawan made one for an example. The chemical change was proven because there was bubbles, temperature change and a color change. I really liked making and eating this breakfast cup.
