Our class is conducting a project to help our school recycle. We are promoting, organizing, measuring, and recording our school’s contribution to recycling before sending to the recycling stations. Due to a budget crisis, we have not been able to come up with an adequate system for weighing the amount of recycling our school has done. **How can we create a system, using resources from our school, that accurately weighs the boxes quickly and takes as little space as possible?**
