Terrariums

During our study of plants, we built a terrarium using a 2L Coke bottle. I cut the bottle in half and then the students added rocks and soil. The students then poked holes in the soil and added seeds. They then covered the seeds with soil and added water. I then added the top. As we built the terrarium, we discussed what plants need. We also discussed what would happen when the water heated up; it evaporates. We connected this back to our lesson on precipitation and how clouds hold water. We placed our terrarium in the science lab so it can get sunlight. After building the terrarium, the students created a foldable to write about and illustrate the steps that they took. We have been visiting to watch the changes in the plant and to see the water droplets forming at the top.
