Scientists, we have a problem!

During an experiment about the properties of materials, the STEM Lab systems suddenly shut down. The lab cabinet has been locked and the materials from the experiment are scattered around the lab.

To restore the STEM Lab, students must investigate the properties of materials and solve each scientific challenge.

Each lock represents a different material property scientists study.

Use observation and scientific reasoning to unlock the lab and restore the STEM system.

Good luck, scientists!
