A Simple Biosphere

Supplies

• A large jar with a lid ( make sure the lid fits tightly)
• A small plant that can fit inside jar with some room to spare
• An area in your house that gets lots of sun-light
• Water
• Masking tape or a marker

Since plants produce their own food they need not get it from an outside source. Under the right conditions, a plant is self sustaining.

A. Water the plant so the soil is moist
B. Put the potted plant into the jar, so that the plant is enclosed.
C. Mark the height of the plant on the side of your jar. Use the masking tape or a marker.
D. Put it in the sun. Check on its progress from time to time. You can keep it as long as you want
E. DO NOT WATER!!!!!!!!!!!!!!!!!!!!!!!!
