Which answer contains the code to draw this image?
Why is the order of the code important?
It is important because it goes from top to bottom.
It is important because if you don't pay close attention to where you put things, you might not see all your shapes.
It is not important.
It is important because following the same order every time prevents you from making mistakes.

Answer the questions below after watching the video
What is one of the key steps in the engineering process?
Final product sale
Testing proposed solutions
Hypothesis creation
Marketing analysis
What should engineers change to test their solutions effectively?
All variables randomly
Only one variable at a time
Multiple variables at once
No variables at all
What does isolating a variable help engineers determine?
The cost of materials
Why a solution works or doesn't
The color of the final product
The marketing strategy
What happens if multiple variables are changed at once during testing?
It is impossible to determine the effect of each variable
It simplifies the test
It makes the test invalid
It helps identify the best variable
What was the successful variable change in the slingshot experiment?
The angle of the slingshot
The size of the slingshot
The strength of the pull
The type of marshmallows
What is the purpose of setting criteria in engineering tests?
To determine the price
To judge the success of a solution
To design the product logo
To choose the project team
In the bowling experiment, what variable was initially chosen to be isolated?
The weight of the ball
The speed of the throw
The color of the ball
The angle of the throw
Why was it difficult to maintain the same speed in the bowling experiment?
The pins were misaligned
The lane was inconsistent
Arm fatigue affected the throw
The ball was defective
Why was using a ball ramp considered in the bowling experiment?
To make the game harder
To increase the fun
To change the ball color
To keep the throwing speed consistent
What ensures a test's success according to the criteria set by engineers?
Changing as many variables as possible
Testing without any plan
Using the most expensive materials
Isolating and testing one variable at a time
What is the main goal of the design process?
To write reports
To make things
To make charts and graphs
To find solutions to problems
What does prototyping involve in the Engineering Design Process?
Selling the final product
Creating a detailed business plan
Building a model or example of the solution
Writing a report on the problem
After testing and evaluating the prototype, what might be a next step in the Engineering Design Process if the solution is not yet satisfactory?
Abandon the project
Start from the beginning
Redesign and improve the solution
Sell the prototype as is
Why is creating a prototype considered a critical step in the engineering design process?
It is the only step that involves physical materials.
It allows the design team to test the solution in the real world.
It is the final step of the process.
It replaces the need for brainstorming.
