"Boyle-ing Water" (demonstration)
Source: James
Spink, Lincoln Hills School
Web site example and explanation
Materials needed: room
temperature water and a plastic syringe (approx. 200-400ml
capacity). Activity is simple but effective. Draw up the water
until syringe is full, push out any air, put you finger over the
end, draw down syringe until a vacuum starts to appear above the
water, keep drawing until water starts to bubble (boiling). The
conclusion is that water is versatile, boils at various
temperatures, moves heat for our planet, and is a key resource. |
