Experiment 1 - “Thinking Metric”Reagents -NoneSpecial Equipment -meter sticks8½"x 11" pieces of paperstring and scissorsrectangular objects such as boxes or blockspieces of chalknickel coins100 tablets (aspirin, vitamin) or other small objectspebbles, rubber stoppers, or metal shotSuggestions and Precautions -The key is to have the students “think metric” rather than to stress conversions.Prelaboratory Questions -1.For: allow for easier importation and exportation of trade products.Against: expense of conversion; resistance to re-education.2.mile, kilometer, meter, foot, inch, centimeter, micron, Angstrom.3.barrel, cubic foot, gallon, liter, milliliter, cubic milliliter.4.The density is less than that of water.5.Overall density, including air cavity, is less; otherwise greater. Bodies can be made tofloat or sink depending on chest expansion.Observations and Results -Part 3- Source of discrepancy - balance is off; personal error. A gram is about a fifth of a nickel’smass. Imagine a nickel that is cut into five pieces. Average weight.Part 4- Wood samples of same kind? - yes; samples of different wood? - no. Relative densities ofwood and water - density of wood is less than that of water. Wood would float onmercury because wood’s density is less than 13.6 g/ml.
