If the TOTAL weight of the water, Kool-aid, and sugar stayed the same before and after mixing the ingredients, what could be a possible reasoning about what you have learned:

• The reason I believe the weight is different before and after the substances are mix is because the sugar dissolves into the water and disappears.

• In class, we learned that when 2 or more substances are combined, the weight of the combined substances will stay the same.

• Based on our experiments in class, the weight stays the same before and after mixing because the scale showed the same number.
