Objective: summarize and articulate lessons learned from Round 1 test [complete part 3 documentation]

Agenda:

Welcome and overview
[Repeat from Friday] Check the figures of merit for each person at your table
1. Revise the cost of your device
  1. Did you use more tape that you budgeted? Was your parachute gigantic? Did you throw away three batches of plaster of Paris? Did you crack an egg or melt the chocolate?
  2. If so, update the cost of your device
2. Speed things up by using this figure of merit calculator
  1. Make a copy for editing access
[Repeat from Friday] DELIVERABLE: Complete part 3 documentation. Submit your documentation in this form due Monday, 17 Nov<2000 PST (8 pm)
[Repeat from Friday] Compare the performance of your heat shield with the performance of others' heat shields
1. Extension: Consider making a radar graph as tool to compare your shield's performance with the performance of others'. Here is a sample
If you have not already done so, refine your conceptual model.
Next steps and closing

Homework:

Due <Tues, 18 Nov @ start of class: We are self-evaluating and peer-reviewing our documentation on Tuesday. Refine all parts of your documentation.

Tuesday, 18 Nov

Objective: evaluate the current state of your round 1 documentation; offer feedback to others to help them improve their documentation

Agenda:

Welcome and overview: new seats
Compile all parts of your Round 1 documentation into a single document
1. Rename Part 1 of your documentation: Round 1 Complete
2. Copy all of Part 2 and paste it at the end of Round 1 Complete.
3. Copy all of Part 3 and paste it at the new end of Round 1 Complete
Give your tablemates commenting privileges to your Round 1 Complete documentation
Self-evaluate your Round 1 Complete documentation and solicit peer feedback
1. Complete the following process using this form (pdf) or Word
  1. Self-evaluate across each of the four standards.
    1. rating
    2. evidence: on what pages should reviewers look for find evidence you have addressed this standard?
    3. justify your rating, share insights, or questions
    4. identify points of pride and areas for growth
2. Solicit peer feedback
  1. Give your tablemates commenting privileges to your Round 1 Complete
  2. Ask them to review and come to consensus on each standard: rating and justification, next steps
3. Evaluate peer feedback: rate the quality of your peers' feedback
4. Deliverable Turn in the completed self-evaluation before leaving class today
Next steps and closing

Plan ahead: Refine your documentation

Wednesday, 19 Nov

Objective: summarize strategies that prevent damage to fragile objects on impact

Agenda:

Welcome and overview
Respond briefly to the following prompt in your science notebook.
1. Identify the characteristics of devices that helped the egg survive the landing test.
2. Identify the characteristics of devices that did NOT help the egg survive the landing test.
3. Offer a tentative explanation why the characteristics you identified in prompts 1 and 2 made a difference in the success of the landing test.
Discuss responses to initial thinking with table groups and class
Investigate how changing the amount of time to stop an object affects force exerted on an object
1. Stopping an egg on a hard surface
2. Stopping an egg on a sheet
Consider: How might you take advantage of this principle in a device where a sheet or net is not feasible?
1. How Crash Land on Mars
2. Aircraft momentum arresters
Next steps and closing

Plan ahead: Momentum quiz on Tuesday, 2 Dec.

Thursday, 20 Nov

Objective: summarize strategies that prevent damage to fragile objects on impact (part 2)

Agenda:

Plan ahead: Momentum quiz on Tuesday, 2 Dec; can you make sense of the questions in this concept checker?

Friday, 21 Nov

Objective: quantify relationship between force, change in velocity, and time

Agenda:

1. Welcome and overview
2. Prior to designing our 2nd round heat shield, we will add some theoretical knowledge to our experience.
  1. Read chpt 7 re: momentum; capture key ideas in your notebook with particular focus on sections 7.1 - 7.3
  2. We will have a brief assessment on Tues, 2 Dec. Be prepared to answer these kinds of questions. Additionally, you should be able to successfully answer questions like the ones in this concept checker?
3. Next steps and closing

Plan ahead: Momentum quiz on Tuesday, 2 Dec
