Physical and Chemical ChangesA Write On Activity
Objective: Chemical/Physical Change: Differentiate The learner will be able to
distinguish between a physical and chemical change.
Examples of signs that are both Chemical & physical Gas production (can be a phase change
or a new substance) Color change (can hold in a color like a
mixture or it could be a new substance) Heat given off (simply hotter or could be
burning to give off heat) Smell (can be expanding out or brand
new from a new substance)
Both of these examples are making a gas. Which one is physical and which is chemical?
H2O in a liquid going into H2O as a gas is a PHYSICAL Change because it still H2O Two different chemicals are being
added to create a new gas or bubbles.
Like Baking Soda & Vinegar making bubbles is a CHEMICAL change
Both of these pictures show a color change due to heat: which is physical and which is chemical?
Paper burning is a chemical change because it is no longer paper, but becomes ash When metals (such as
steel) heat up they glow but they are still the same substance (still steal)
