Why Measurement Just as effective science instruction is impossible without a laboratory, no laboratory experience is possible without measurement and recording physical variables. Measurement is one of the easiest topics to cover and measurement integrates completely with mathematics.
Measurement is only linear.
Area and volume and perimeter are the same. You can only measure the smallest unit on the measuring instrument. Mass and volume are the same thing. Mass and weight are the same thing. You should start at the end of the measuring device.
