Answer:
Ideas for Prototype Design
Similar to a cardboard oven just smaller and solar powered
Preliminary Sketches (attach separate paper, if needed)
Option A: i gave the picture
____________________________________________________________
Advantages: Disadvantages:
● the tin foil will attract the sun● if theres enough heat for the food to warm up
●the plastic will keep bugs and/or animal away from getting it ● it might take longer
●the box gives the food something to be in instead of the ground
Option B: i think im going to stay with my original plan i can always make changes
__________________________________________________________
More advantages and disadvantges
Advantages: Disadvantages:
●reducing my carbon footprint by alot ● heat varies so the food my take really really long
●using no energy other than the sun
__________________________________________________________
Which of the three designs will you move forward with? Explain your reasons for selecting this design.
I will be moving forward with option A bc i personally can't think of another way or design and i think option A has more advantages than disadvantages
__________________________________________________________
Building the Prototype
What modifications, if any, did you make to the basic design during the construction process?
I used skewers to hold the flap up
__________________________________________________________
Predictions
Will your device warm the hot dog to a temperature of 165°F? How will your device do this?
Well i guess it depends n alot of things such as where i will place my solar cooker and the weather changes i will most likely put my solar cooker on the black paper because darker colors absorb more heat then lighter ones, then i will wait maybe 10 -20 minutes and check on my hotdog
__________________________________________________________
Will your device efficiently warm the hot dog in 20 to 25 minutes? How will your device do this? so my device will do this by attracting the suns rays and energy towards the box
__________________________________________________________
Will your device reach a temperature well above that of its surroundings? How will your device do this?
I think so especially if i put it in direct sunlight around a darker surface and of course the aluminium foil will help with this as well
__________________________________________________________
Observations
Record your observations and the results of the experimental tests of your device below. Temperature of the surroundings (in °F): ______68_______
Maximum temperature reached inside the solar cooker (in °F): _____59_____
__________________________________________________________
i added a picture but i will also put the numbers here althought keep in mind u might want to switch them up because its based off of my temperatures
Use this table to record the internal temperature of the hot dog every 2 minutes. Use a separate sheet of paper, if necessary.

Evaluating Your Prototype
What worked well?
i would say definitely the black paper and tin foil sin they attracted most of the suns energy
__________________________________________________________
Which features can be improved upon?
i think maybe if i did t on a different day it would have gotten hotter
__________________________________________________________
How could the overall design of this device be improved?
Position the flap more so that the hotdogs can get more sun
Doing it on a hotter day
Letting it cook longer
__________________________________________________________
Why would this change be an improvement? What concepts related to thermal energy transfer is this improvement based on?
this change would be an improvement by the hotdogs getting warmed to the right temperature this is related to thermal energy by the position of the flap i think if i angled it more in an abtuse angle the sun would have transferred to the foil to the bottom foil with the hotdogs

Sketch of Your Final Design
Draw a well-labeled sketch of the final design.
i provided a sketch it should be the last picture
OKAY FINALLY PLZ DONT REORT THIS I WORKED SO HARD ON IT LAST TIME AND IT GOT DELETED IF U HAVE ANY QUESTIONS ABOUT THE PROJECT I WILL TRY TO HELP YOU IN THE COMMENTS THANK YOUUUU - ( if your wndering what grade i got on this got a 100 percent )
OH AND PEACE.
