Look to yesterday’s post to see about tonight’s homework.
When you think about chemical and physical changes think about this:
Did the object stay the same, but you just changed the size, shape, color, texture, hardness, or state (gas, liquid, solid)? If so, you have made a PHYSICAL CHANGE.
Did you create something new, something that wasn’t there when you started (like bubbles or a lack of color where there was color before)? If so, you have made a CHEMICAL CHANGE.
