Today's Topic:Pumps and Siphons
drinking straws (the kind that bend)
clean and empty handsoap dispensers
Fire truck / Oxlade, Chris
There might be better books out there about pumps and/or siphons, but this was the best I could find for today's class. The kids LOVED reading about fire trucks and this one has quite a bit to say about the water pumps found on an engine.
What Kids Do:
play with the water pumps
other ways to get water out of the water pumps
explore the power of the pump soap dispensers
Can you make it longer? (hint: yes! But it helps to have some extra hands.)
Learn how to siphon water using a drinking straw and a cup.
Control the flow of water by pinching the straw.
Make super long straws!
Adult Challenge of the week: Ask "what could you change?" to foster the concept of experimentation.
Hindsight Tip: This is another great one to reserve for a day when you can take the action outdoors. I loved watching the kids come up with all sorts of alternative machines to move water. They made combinations I never would have considered--and some of them worked!
