Objective: estimate amounts to create your design

Agenda:

Welcome and overview
Estimate amount of materials needed to build your heat shield
1. Review calculations for lines, areas, and volumes ppt or pdf
2. Guided practice Word or pdf
3. Independent: Estimate amounts needed for YOUR design.
  1. Make a copy of this template; save it to your Thermodynamics folder
  2. Success criteria
    1. List each material you will use
    2. Identify its main purpose, location, type of measurement, and estimated amount
    3. Make a reasonable estimate the amount of material you will use
4. Deliverable Complete the estimated amount of materials required to build your device
Next steps and closing
1. Plan ahead: On Thursday, you will complete a self- and peer-design review. Rubric is here

Homework:

Due Tuesday, 21 Oct @ start of class: Completed estimate for each material [agenda item 4]

Plan ahead:

Due Thursday, 23 Oct @ end of class: Completed design review and refined conceptual model and technical sketches [agenda item 5]

Tuesday, 21 Oct

Objective: use estimated amount of materials to create a budget

Agenda:

Welcome and overview
Engage
1. Suppose you are planning a party. What's the three best foods to eat at a party?
2. If you were planning a party for 10 people, how much of each type of food would you know to buy?
Calculate the cost of the materials to create your design
1. Review requisition list
2. Review your materials list
3. Calculate the cost of materials needed to create your design
  1. Model & guided practice
  2. Independent practice
Revisit your design to reduce anticipated costs
1. Think about the way your materials will distribute energy in strike test, heat test, and landing test. Are there other, less expensive materials that might accomplish the same goal?
2. How does cost change if you use different, less expensive materials?
3. Deliverable Updated materials list and budget
Plan ahead: Refine your conceptual model and technical sketch to match your budget

Being curious is fun. From the "What If?" archives

Toaster vs. Freezer
Microwaves
Snow removal
Laser umbrella

Plan ahead:

Due Thursday, 23 Oct @ end of class: Completed design review and refined conceptual model and technical sketches [agenda item 5]

Wednesday, 22 Oct & Thursday, 23 Oct

Objective: solicit feedback on your design; offer feedback for others' designs

Agenda:

Welcome and overview
Which is better?
1. Strike test: cardboard or plaster?
2. Heat test: fiberglass or cotton balls?
3. Landing test: newspaper or polyethylene?
Price of being overbudget
1. Figure of merit: details calculator
Design review
Use the information from the self-evaluation and peer review to refine your model and technical sketch
1. Your instructor has additional print copies of conceptual model and technical sketch available
Deliverable
1. Paperclip the following together in this order
  1. Completed design review [self AND peer]
  2. Hard copy of clean, crisp, and completed conceptual model
  3. Hard copy of clean, crisp, and completed technical sketch
2. Completed survey
  1. Ensure that your Materials List & Cost Estimate is in your 01 Thermodynamics folder
  2. Change permissions on Materials List & Cost Estimate so that anyone with the link can comment
  3. Paste the link in the survey
  4. Reflection
Next steps and closing

Homework:

Due Thursday, 23 Oct <end of class: (1) hard copy of completed design review, conceptual model, and technical sketch and (2) completed survey: materials, budget, reflection

Friday, 24 Oct

Objective: describe three different techniques used by heat shield designers in the past; compare their techniques to yours

Agenda:

1. Welcome & overview
2. When we introduced this unit, we saw the importance of puncture-resistant heat shield tiles.
3. In today's lesson, we will review different strategies that NASA has used in the past. What are some ideas that we've explored might be applied to actual heat shields?
  1. Systems engineer: Facilitate a conversation with your table group; ensure that each voice is heard
  2. Science officer: probe for science
  3. Communications: Share with the large group
4. Read this article about the evolution of heat shield designs [a printed copy will be available in class]
  1. In your notebook, define key terms and summarize key ideas
    1. Blunt body
    2. Ablation
    3. Transpiration
    4. Heat sink
    5. Beta
    6. Plasma torch
  2. DELIVERABLE
    1. Level 3: demonstrate your understanding by accurately responding to questions in this form due <Sunday, 26 October
    2. Level 4: complete level 3 AND complete a brief set of research on a heat shield of interest to you; submit your work in this form due <Tuesday, 28 October
      1. Success criteria:
        
        content
        
        title page
        
        context: where and when was it used? Who developed it?
        
        components: what are the major features?
        
        physics: In diagrams and your own words, briefly show and explain how the device withstands or disperses the energy of re-entry
        
        citations
        
        accurate and representative of YOUR thinking
        
        visually appealing
