Turn your classroom into a greenhouse with a lesson on plant growth. First, investigate the different parts of seeds, identifying the seed coat, cotyledon, and embryo. Then plant the seeds and watch them grow! Measure the new plants every couple of days to document their growth, moving some into a dark corner of the room to demonstrate their dependence on light. To ensure student success, model each step before allowing your young scientists to proceed with the experiment. Though somewhat time consuming, a great deal can be learned about plant life, as well as how to record and analyze scientific data.
