Frankenstein Tomato Plants (FTP) • Hands-on Engineering Design • Middle School Life Science • Full Lesson • Reading Activity • Exploration Activities • Design Activity
FTP: Group Packet We’ll read through and discuss • Lesson Plan • Reading • Vocab Alert! • Exploration Activity • Design Activity • Design Results Our focus today
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
Heirloom Seedlings Heirlooms can be planted two to a pot.
Deli Container Set up Water Reservoir
Cutting Technique Cut stems against a hard surface.
Horizontal Graft Graft Scar
Vertical Graft Graft
Vertical Graft After Successful graft but lots of vascular tissue indicating a poor cut.
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.
Cleft Graft After Front View Side View
Side Graft For side grafts a rootstock and heirloom should be planted in the same pot.
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.
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?
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?
