Background Research.
Write 2 paragraphs that summarize what you learned in the Learn section. Make sure you include the information related to your choice of insulating materials.
Brainstorm Solutions.
Describe (draw/write/label) your initial design ideas. Include annotations, questions, measurements, sources (where you found the information) NOTE: There are just your ideas. You will describe your prototype in the next section.
Some materials to consider, along with their thermal conductivity value:
Build a Prototype.
Select a possible solution. Draw your initial design before you even consider building. Take your time and put effort into this drawing. It should include clean lines, measurements, labels, at least two perspective (cut away and top down), materials, and notes.
Test your Prototype.
Congratulations. You have built your first prototype and are ready to begin initial testing. Your initial tests should include the following:
-
Size: Will it fit in your teacher’s hand?
-
Water holding ability: Will your prototype hold 250 ml of water?
-
Structure: Is your prototype build to last? Is it structurally sound?
-
Insulation: Will it keep 250 ml of water warm for 30 min or longer?
Make sure you include a brief description of each test and column/row headings for tables and units for all data.
Communicate results.
Now that you have tested your device, what have you learned? Is there more research you need to conduct? Are there changes you wish to make to your design? Summarize your test results and the next steps you plan to take. If you are considering a new design, attach the new blue print to your design brief. Make sure you include the graph of your results. This is individual work.
Redesign/Test/Communicate.
Continue with your design, building and testing. Record all changes you make to your design, include your revised design drawings, test data summaries and conclusions.
Final Build / Communicate.
Complete a final build based on your results. Write a summary that includes the problem you worked on, how your ideas changed from the first to final prototype, how heat tranfer worked in all your designs and which method was the most efficient at retaining heat. Make sure you cite your evidence as you explain your results.
