Structures of Life
Investigation 2: Growing Further
Part 3
Life Cycle of the Bean
Students grow seedlings in nutrient solution and observe and illustrate their life cycle.
3. Lesson set up and Management
1.2.L.2 Describe the life cycles of plants.
1.3.L.1 Recognize that living things need constant energy supplied from food or light.
1.3.L.3 Describe how its environment, other life forms, and availability of food and/or other resources influence an organism's behavior and ability to survive.
Plants need water, light, and nutrients to grow.
The life cycle is the process of a seed growing into a mature plant, which in turn produces seeds.
The fruit of the plant develops from the flower.
3. Lesson set up and Management
Materials:
1. Set up a schedule for observing and measuring plants for approximately 2 months. Measuring on the same day each week is best for accurate growth rate. You will still be observing the plants as you are completing the crayfish and snail investigations.
2. Be sure to tear apart bean pods when the plants are between 6-7 cm long.
3. Make sure student sheet No. 9 is in the student packet.
4. Complete student sheet No. 10 on an overhead together as a class.
5. If kids will be taking home plants at the end of the kit, start having them bring in containers now so you are ready when the day comes. Be sure to also have potting soil.

When measuring new plants you need to be careful. As plants grow, carefully straighten them for easier measuring. |
Student Management:
1. Keep all materials at the station at which the students are working. Let the students go to each workstation and explore.
2. Set rules and guidelines for observing the plants during non-science times.
4. Keep Moving! If you are constantly moving, it will keep everyone on task.
1. You can lengthen or shorten the time on any lesson.
2. Use pages 2 & 3 to help guide further inquiry at the end of every section.
3. Don't forget to keep observing on the same day each week for accurate growth rate.
4. Give students time to discuss their observations with each other.
5. Keep word banks and content inquiry charts up so students can see and have more time to copy later, if needed. It's nice if you can keep them up all the time and just add to them as you go.
Writing Support:
1. Have students reflect on the day's lesson in their journal.
2. Start and finish each lesson with a KWLQ chart. ("What do I know?" "What do I want to know?" "What have I learned?" and "Are there any more questions to investigate?")
3. Have students write all word banks and inquiries in their journals.
Reading Support:
1. Read FOSS Science Story Seeding Space.
2. Check the Resources section of the teacher's guide for more reading suggestions, or the literature link on this site.
