Matter Matters

As part of their curriculum first grade students in Woodside School study about the three states of matter.  Mrs. Wolf takes things one step further in the SAGE program when the students experiment to prove that air takes up space, has weight, and has pressure.  When a cardboard “sticks” to an overturned glass of water it seems like magic.  But it just shows that the air pressure pushing up on the card is greater than the pressure pushing it down.  The students act like molecules changing from solid to liquid to gas as they pretend to heat up.  All matter is made of molecules and matter matters.
