Building a Closed System Terrarium
You could do this together, step by step or give them all of the materials and information needed to do it by themselves.
Could be a group activity or an individual activity so each student can take home a terrarium
Succulents and Cacti will not work in closed system terrariums
Opportunity to show students how to propagate spider, ivy and other plants that can possibly go into the terrarium. You could also have students buy their own plants.
