What happens to the water in the rain barrels if they get full?
Organize and reflect on documentation After several days of water activities, in their subsequent discussions with the children, the KWL chart was revised to add:
K: Spray bottles are pumps (but we dont know why they work); some water can go up without a pump; we can make water go faster if we make it steeper; water can move dirt to make little rivers; some of our designs worked really good, but others not at all; does the water in the sink and bathtub have a pump?
W: How does a pump work? How can water go up without a pump? Do rivers only go downhill? What happens to the water in the rain barrels if they get full?
L: We need to ask the engineer to come over and explain how the rain barrels work; we can look on the Internet to find out more about pumps; maybe the engineer can tell us about pumps, too.
