Cut the plastic bottle about midway. You will use only the rounded clear part for this project. Pull the colored bottom away from the clear plastic. Fill the colored plastic bottom of the bottle with soil. Arrange the plants in the soil.
Drop seeds around the soil.
The water cycle will be working. Students will note the plant growth by taking daily measurements from the outside of the bottle. Each student will keep a journal with the information they gather. When students have entered the classroom, have them describe what is happening in the terrariums. Students then brainstorm verbally and record on the board what processes are occurring within the terrarium.
