Measure forces and weights in the science classroom using this scale! This tubular spring scale is easy to read and use for students and teachers alike. Units of measurement are in both Newtons and grams, and a helpful hook allows for the scale to be hung anywhere in the classroom. This version of the scale is colored green for color-coding purposes and measures up to 500 grams/5 Newtons. Use it to measure magnet strengths, weight lab objects, or experiment with kinetics via pulleys.
