OverviewThe children were working with levers and other simple machines. The children wanted to know if water could be used as a machine to lift a load. The whole class talked about machines and possible ideas were encouraged and once the ideas were presented to the whole class, a design for a machine was created.
What We Thought We Knew
Questions We Had
What We Found Out from Books, the Internet, and ExpertsWe found simple machines in the book, "101 Great Science Experiments" by Neil Ardley, Dorling, New York, 1993
The problem statement, "Can water be used to lift a load?" will be expanded on by each student in the class.
What We Found Out from ExperimentationThey found out that water could be used to lift and load and they found out the importance of water pressure. Where there were leaks, the water failed to lift objects, and the class concluded that tight fitting joints that did not leak worked because you needed water pressure to lift objects.
How We Showed What We LearnedPictures were taken of the actual experimentation in the class. Students made diagrams of the simple machines we created.
