 * COS# 7 Describe the life cycle of plants, including seed, seed germination, growth, and reproduction. **

The students have been participating in a unit called plant growth and development for 9 weeks. The seed (brassica seed) in which they have observed completes the whole life cycle in 6 weeks. They observed the bean seed, planted the brassica seed, observed the distinct stages, determine what the plants needed to grow, pollinated with a real bee in order to produce seeds, graphed the stages of growth, and observed/described/recorded their findings after the flower is harvested. The students created another graph that compared their number of seeds. They were able to use a bar graph, line graph, or pictagraph. We took this project one step further. We decided to study the life cylce of vegetables and compare the two. We rearched the life cycle of a vegetable in the computer lab. The students then created a chart on Microsoft Excel that showed how many days it takes for certain vegetables to mature and be ready to harvest. The students went shopping with their parents at a super market or farmers market and brought in vegetables to class. We took those vegetables and dehydrated them to make dry soup. We also had a guest speaker.

**One seed produces one plant, but one plant can produce many seeds.....**
