Designing a Trial

The video emphasizes the importance of precision in engineering, using examples like bridges and bowling alleys. It recaps key engineering concepts such as criteria for success, identifying variables, and isolating one variable for trials. The video then demonstrates these concepts through a ring toss experiment, highlighting the process of identifying failure points and adjusting variables. It concludes by stressing the need to pay attention to details and consider multiple tests.

Why is precision important in engineering solutions?

• Because it saves time and resources.

• Because it is easier to achieve than accuracy.

• Because it ensures the solution meets the desired outcome.

• Because it allows for more creativity.

What is the first step in the engineering process as discussed in the recap?

• Identifying failure points.

• Changing multiple variables at once.

• Conducting trials.

• Setting criteria for a successful solution.

In the engineering process, why is it important to isolate one variable during trials?

• To make the experiment more complex.

• To ensure the results are due to the change in that variable.

• To increase the number of trials needed.

• To save time during the trials.

What was the criteria for success in the ring toss game example?

• Getting the ring around the pin in one throw.

• Getting the ring around the pin in multiple throws.

• Standing as far away from the pin as possible.

• Using the largest ring available.

What was identified as a failure point in the ring toss game?

• Standing too far from the pin.

• Standing too close to the pin.

• Throwing the ring too softly.

• Using a smaller ring.
