Lesson: Measuring lab (Sciencespot.net)
The activity is a good way to have students work with a partner to practice the skills that they have learned, such as converting metric units and proper measuring techniques (using a ruler).
Tips: for number 4 (e-g) you may want to draw 2 circles on the board and label the radius on one and the diameter on the other. Middle schools inevitably have the same questions over and over, so you can just point to a visual of radius and diameter if they forget what they are. #5: pass an unsharpened pencil around the room and have each partner group measure it and then pass it along to the next group. I set up a station in the back of the room for #6. I tell students to mark their partners height with their hand on a wall and then have the student step away to measure their own height. Students then switch duties so that each one has a turn measuring their own height. I set up another station in the back of the room for #7. I tape two index cards to the floor and then have students measure using meter sticks. This is also draw on the board to address any confusion on how to measure. Each group takes a turn going to stations 6 and 7. They are responsible for letting the next group know when it's their turn to go back to measure.
