A terrarium - Mary, Mary quite contrary

How does your terrarium grow?

First get a glass jar, then one quarter fill it with soil and add some plants. You can use moss or plant a small potato, or some apple seeds or an attactive small weed from your garden.

Water it carefully without making it too moist and put on the lid. Keep your terrarium in a well-lit, warm place and watch how the plant grows in its own little environment.

We did two terrariums in our class. One had ventilation holes in the lid and one terrarium remained sealed.

We predicted the outcomes in the two terrariums, would one survive or would both? We wrote a word bank and researched the respiration rate of plants. We compared desert plants and their needs to tropical rainforest plants.
