Weighing Candy
Fri, Nov 2, 2012
Materials: Spring scale made from a 2L bottle, pipe cleaner and a spring.
Activity: Make a spring scale to weigh your Halloween Candy, rocks and mulch. Add a few rocks to a bucket. Weigh the bucket with the spring scale by measuring how far the spring is stretched. Add a few more rocks and watch what happens to the spring. Dump out the rocks. Fill the bucket with enough mulch to weigh the same as the rocks. Dump out the mulch. Compare the rock pile and mulch pile.
Research Question: How does the weight in your bucket affect how far the spring stretches?
