Students use proportions to find the height of the flagpole in front of the school. Convert measurement units from one form to another, and carry out calculations that involve various units of measurement. Students are given a ring and asked to find the height of the person who lost the ring. They measure their own fingers and their heights, plotting the data on a coordinate graph. They use a piece of spaghetti to fit a straight line to the plotted points and make a prediction about the height of the person who owns the ring, based on the data they have collected.
Students plan the weird name Olympics by renaming standard events in different measurement units.
1000 ml of water normally weighs about 1 kg 14. Understand and apply measurement in their own lives and in other subject areas. Students design and carry out an experiment to see how much water is wasted by a leaky faucet in an hour, a day, a week, a month, and a year. Students are told that when people get out of a bath, a film of water about 0.05 cm thick clings to their skin. They are then challenged to find what volume of water clings to the skin of an average eighth grader.
