Presentation Transcript

  1. Frankenstein Tomato Plants (FTP) • Hands-on Engineering Design • Middle School Life Science • Full Lesson • Reading Activity • Exploration Activities • Design Activity

  2. FTP: Group Packet We’ll read through and discuss • Lesson Plan • Reading • Vocab Alert! • Exploration Activity • Design Activity • Design Results Our focus today

  3. FTP: Today's Activity • Review the Activity Handouts starting with reading handout • Discuss and Complete the Problem and Criteria and Constraints Sections • Sketch Two Initial Designs • Build Prototypes • Analyze • Clean up

  4. Rootstock Seedlings

  5. Heirloom Seedlings Heirlooms can be planted two to a pot.

  6. Deli Container Set up Water Reservoir

  7. Reflector Lamp Set Up

  8. Cutting Technique Cut stems against a hard surface.

  9. Horizontal Graft Graft Scar

  10. Vertical Graft Graft

  11. Vertical Graft After Successful graft but lots of vascular tissue indicating a poor cut.

  12. Failed Graft In this case the grafted seedlings were too small for the clip. As a result the connection between the two plants was loose and never fused.

  13. Cleft Graft

  14. Cleft Graft After Front View Side View

  15. Side Graft For side grafts a rootstock and heirloom should be planted in the same pot.

  16. Reusable Rootstock If the first grafting attempt fails, many rootstocks can be reused. In this picture the rootstock is starting grow new leaves indicating its viability.

  17. Grafting Chamber

  18. FTP Reflection • How will your students identify the science involved? • What factors affect successful grafting the most? • Which designs were the most effective? Why?? • What was the most difficult part of this activity? • What could be done to improve it?

  19. Small Group Discussion • Characteristics and benefits of Engineering Design. • How does the Engineering Design Process differ from Science Inquiry? • What other activities can you modify to use Engineering Design? • Problems you anticipate and how to resolve them? • Biggest roadblock to using the Engineering Design Process?
