Ethanol Burning: As a class

How have your ideas / explanations changed?

What do you know now that you didn’t know before?

How has the scale of your thinking changed?

Materials Card Sort

1 Minute

Examine the cardsSort the materials into two piles

Use any rules you choose for creating the two piles

Be ready to share your reasons

Why can some things burn while other things cannot burn?Why does ethanol behave more like wood than like water?

Chemical Energy

Energy found in the bonds of molecules. C-C and C-H bonds means molecules have available chemical energy.

So which materials have available chemical energy?

MATTER AND ENERGYEvery molecule has both ATOMS and BONDS

ATOMS TELL YOU ABOUT MATTER

BONDS TELL YOU ABOUT ENERGY
