Mini Compost Bins

Students will design a model of an efficient compost bin using Tinkercad or another CAD software program. Depending on the size and complexity of the models, you could print each student's design or print one design per class. Images of finished student work Notes from contributor: This project is part of the STEAMTrax Designing an Efficient Compost Bin module. Prior to working through the module, students spent several weeks learning about ecosystems and the flow of energy through an ecosystem. Students (in groups of 4) observed and recorded the physical and behavioral characteristics of the plants and animals in their classroom ecosystems.
