Imagine you are a civil engineer who designs buildings. How might testing small-scale building models or their components be helpful in testing improvements and changes to the building design? is for my science class

Summary
Students learn about the types of possible loads, how to calculate ultimate load combinations, and investigate the different sizes for the beams (girders) and columns (piers) of simple bridge design. They learn the steps that engineers use to design bridges by conducting their own hands on associated activity to prototype their own structure. Students will begin to understand the problem, and learn how to determine the potential bridge loads, calculate the highest possible load, and calculate the amount of material needed to resist the loads.
This engineering curriculum aligns to Next Generation Science Standards (NGSS).
Engineering Connection
Engineers who design structures must completely understand the problem to be solved, which includes the complexities of the site and the customer needs. To design for safety and longevity, engineers consider the different types of loads, how they are applied and where. Engineers often aim for a design that is strongest and lightest possible—one with the highest strength-to-weight ratio.
Learning Objectives
After this lesson, students should be able to:
List several examples of loads that could affect a bridge.
Explain why knowledge about various loads or forces is important in bridge design.
Describe the process that an engineer uses to design a bridge, including determining loads, calculating the highest load, and calculating the amount of material to resist the loads.

Pre-Req Knowledge
The students should have a familiarity with bridge types, as introduced in the first lesson of the Bridges unit, including area, and compressive and tensile forces.
Introduction/Motivation
We know that bridges play an important part in our daily lives. We know they are essential components of cities and the roadways between populations of people. Some bridges are simple and straightforward; others are amazingly complex. What are some bridges that you know that might be called simple bridges? (Possible answers: Log over a creek, bridges over streams.) What are some bridges you know that might be considered more complicated? (Possible answers: Golden Gate Bridge, other large bridges, bridges that carry both highway traffic and train traffic.) What makes some bridges simple and other complex? (Possible answers: Their size, multiple purposes, environmental conditions, environmental forces, material maintenance requirements, etc.)
One amazing example of a bridge's contribution to connecting people to other populations and places for both social and commerce reasons is the Sky Gate Bridge connecting people to Japan's Kansai International Airport, located in Osaka Bay.
It all started when the nearby Osaka and Tokyo airports were unable to meet demand, nor be expanded. To solve the problem, the people of Japan took on one of the most challenging engineering projects the world has ever seen. Since they had no land for a new airport, they decided to create the Kansai International Airport by constructing an entire island! On this new, artificial island, they built the airport terminal and runways. Then, they needed a bridge to access it. Spanning 3.7 km from the mainland in Osaka to the airport in an ocean bay, the Sky Gate Bridge is one of the longest truss bridges in the world and has an upper deck for auto transport and a lower, internal deck for rail lines.

Cramming is a common study technique used to get ready for an exam or other performance-based test. Cramming is a technique used to memorize a lot of information quickly. It is most popular among students in high school and college. Thus, option B is correct.
What are the benefits of finishing test early?It's best to cease studying 12 to 24 hours before the exam, advises Grunewald. You won't discover much fresh information.There is a far greater chance that you may confuse and stress yourself out. Flashcards are a useful study aid for those who are studying on short notice.
According to research, taking deliberate breaks (anywhere between 5 and 60 minutes) from studying to recharge your mind and body enhances your energy, productivity, and capacity for concentration. Remember that social media is not a good “purposeful break” (see the research).
Therefore, make sure your answers correspond to the right questions.

Alright everyone. I have to take the PSAT and I'm a bit nervous. I'm not even supposed to take them in the eight grade so I'm even more nervous. How should i calm my nerves?
Answer:
HI i took the psat 2 days ago, and do not stress at all, I had stressed so much before I took it, but really, it nothing to stress about, this is a practice test, so when you take the SAT in the near future, you know what specific things you need to work on all along, just remeber all along the test that this is a PRACTICE test, so really there no need to stress, make sure you get a good night sleep and eat food before you go take it:)

can you think of a possible explanation for the change in the thickness of the ozone layer in the years before the methyl bromide began to produce
Answer:
Explanation:
Methyl bromide is a fumigant used to control pests in agriculture and shipping. Methyl bromide also depletes the ozone layer. Therefore, along with other countries, the United States has phased out production and consumption of methyl bromide with important exceptions for critical uses as well as quarantine and preshipment.

When you are simply guessing in any test subject, which bubble should you fill in? *
2 points
None of them, leave it blank.
Pick a different answer choice for each guess.
It doesn't matter which answer choice you pick, as long as you use the same one each time you are guessing.
B and only B - no exceptions
Answer:
My teachers always told me to choose B if I'm guessing and don't know the answer. Its a greater chance that the answer is B than any other choice. So I would say choose B and only B
