40 points For this assignment, you will research how to design and build a solar cooker. Search reliable online sites
for “solar cookers.” After getting the materials you need from your teacher, you will present your initial
design as a drawing or illustration. You will then build your device and test its efficiency by warming up a
hot dog until it reaches an internal temperature of 165°F, recording how long it took you to reach this
temperature. Based on your tests, you will make recommendations on how to improve the design of your
solar cooker, and then present your final design and the logic that supports it in a lab report. Your lab
report should include a title, a list of materials that you used to build your solar cooker, a drawing of your
initial design, observations from your experimental tests, recommendations for a final design based on
what you know about radiation, a drawing of your final design, and the results of the efficiency test. To
help you write your lab report, there is a Student Worksheet on the last few pages of this document.

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.

relativism, roughly put, is the view that truth and falsity, right and wrong, standards of reasoning, and procedures of justification are products of differing conventions and frameworks of assessment and that their authority is confined to the context giving rise to them. more precisely, “relativism” covers views which maintain that—at a high level of abstraction—at least some class of things have the properties they have (e.g., beautiful, morally good, epistemically justified) not simpliciter, but only relative to a given framework of assessment (e.g., local cultural norms, individual standards), and correspondingly, that the truth of claims attributing these properties holds only once the relevant framework of assessment is specified or supplied. relativists characteristically insist, furthermore, that if something is only relatively so, then there can be no framework-independent vantage point from which the matter of whether the thing in question is so can be established.

relativism has been, in its various guises, both one of the most popular and most reviled philosophical doctrines of our time. defenders see it as a harbinger of tolerance and the only ethical and epistemic stance worthy of the open-minded and tolerant. detractors dismiss it for its alleged incoherence and uncritical intellectual permissiveness. debates about relativism permeate the whole spectrum of philosophical sub-disciplines. from ethics to epistemology, science to religion, political theory to ontology, theories of meaning and even logic, philosophy has felt the need to respond to this heady and seemingly subversive idea. discussions of relativism often also invoke considerations relevant to the very nature and methodology of philosophy and to the division between the so-called “analytic and continental” camps in philosophy. and yet, despite a long history of debate going back to plato and an increasingly large body of writing, it is still difficult to come to an agreed definition of what, at its core, relativism is, and what philosophical import it has. this entry attempts to provide a broad account of the many ways in which “relativism” has been defined, explained, defended and criticized.
