What is the main function of the "test and evaluate" step in the engineering design process?
To determine if the solution works as intended
To brainstorm ideas
To write a report
To draw a sketch
Which of the following best describes a prototype?
An early model built to test a concept
A final product ready for sale
A written report
A mathematical formula
What is the main reason for using a pinhole instead of a lens in a pinhole camera?
To focus light without using glass
To increase the brightness
To add color to the image
To use electricity
Which of the following best explains why it is important to date every entry in an engineering notebook?
To provide a timeline of the design process
To make the notebook look neat
To use up more pages
To add color to the notebook
When documenting a failed prototype in your engineering notebook, what should you include?
The reasons why it failed and possible improvements
Only the final design
Personal opinions unrelated to the project
Blank pages
If the image in a pinhole camera is too dim, which adjustment would most likely help?
Increase the size of the pinhole slightly
Decrease the size of the pinhole
Use a colored screen
Add a lens
Which of the following is an example of applying the engineering design process in daily life?
Designing a more efficient way to organize your desk
Watching television
Reading a novel
Sleeping
Why is it important to use permanent ink in an engineering notebook?
To ensure entries cannot be erased or altered
To make the notebook heavier
To add color to the pages
To save money
If you want to capture a moving object with a pinhole camera, what challenge might you face?
The image may be blurry due to long exposure time
The image will be in color
The camera will overheat
The image will be upside down
Which of the following best demonstrates the use of evidence in the engineering design process?
Testing a prototype and recording the results
Guessing the outcome of a design
Ignoring test data
Skipping the testing phase
If you are asked to redesign a pinhole camera to make it more portable, which material would you most likely choose?
Lightweight plastic
Heavy metal

Concrete
You are tasked with designing a pinhole camera that can capture clearer images in low light. What strategic change would you make to the design?
Increase the exposure time and optimize the pinhole size
Use a smaller camera body
Add more decorations to the camera
Use a colored filter
A team is working on a new product and records all their ideas, sketches, and test results in an engineering notebook. How does this practice support the team’s ability to defend their design decisions?
It provides documented evidence of their process and reasoning
It makes the notebook look full
It allows them to skip testing
It helps them avoid teamwork
You notice that your pinhole camera produces images that are not centered on the screen. What reasoning process would you use to identify and solve this problem?
Check the alignment of the pinhole and adjust the position of the screen accordingly
Change the color of the camera body
Add a lens to the camera
Use a larger box
A student wants to improve the documentation in their engineering notebook. Which strategy would most effectively enhance the clarity and usefulness of their entries?
Use clear headings, detailed sketches, and thorough explanations for each step
Write only the final results
Use random colors for each entry
Leave blank pages between entries
You are testing two different pinhole sizes for your camera. How would you plan an experiment to determine which size produces the sharpest image?
Test both pinhole sizes under identical lighting conditions and compare the image sharpness
Use different cameras for each test
Change the screen material for each test
Test only one pinhole size
During the engineering design process, you encounter a failed prototype. What is the most strategic next step?
Analyze the failure, identify the cause, and modify the design accordingly
Discard the project entirely
Ignore the failure and continue
Repeat the same test without changes
A group is designing a pinhole camera for outdoor use. What factors should they consider to ensure the camera works effectively in bright sunlight?
Use a smaller pinhole and a less sensitive screen to prevent overexposure
Use a larger pinhole and a highly sensitive screen
Add a flash to the camera
Use a transparent camera body
You are reviewing your engineering notebook and notice some entries are unclear. What reasoning process should you use to improve the quality of your documentation?
Revise the entries by adding missing details, clarifying sketches, and explaining your reasoning
Erase the unclear entries
Ignore the unclear entries
Add unrelated information
A pinhole camera is being redesigned to capture images of fast-moving objects. What strategic modification would you recommend?
Decrease the exposure time and increase the sensitivity of the screen
Increase the size of the camera body
Use a colored filter
Add a decorative cover
You are tasked with presenting your engineering design process to a panel. What is the most effective way to communicate your process and results?
Use your engineering notebook to provide a step-by-step explanation, supported by data and sketches
Only show the final product
Read random entries from your notebook
Skip the explanation and show a video
The favorite recipe assignment was important to chemistry because ...
In a recipe there are ratios and when there is a chemical reaction you must have enough reactants to make your desired product
If you need more product then you must double your reactants like in a recipe
simple math is learned in both cooking and chemistry
reactants are like ingredients and if you don't have enough you will still make all the product you want.
What is the ratio of tomatoes to onions in this pico de gallo recipe?
1 pound to 1/2 cup
1/2 pound to 1 cup
1 tomato to 1/2 onion
1/2 tomato to 1 onion
