Teachers: Slow Rot or Not?
Slow Rot.or Not! In this science lesson, students will discover how different environments affect materials that easily decompose, such as ancient sandals made of plant fibers. They will formulate and investigate their own preservation theories by observing how grapes decompose in five different environmental settings. They will hypothesize how particular environments will affect their "artifact," record observations of the grapes' changing properties over a 10-day period and, finally, form conclusions based on their research. Suggested for grade level 5.
