What types of measurement are you familiar with?
I am familiar with physical measurements such as length, weight, temperature and time.
What can you measure with the SI system of units?
We can measure time, length, mass, electric current, temperature, amount of substance and luminous intensity with the SI system of units.

What are some types of numbers?
Those ten simple symbols, digits, or numbers that we all learn early in life that influence our lives in far more ways than we could ever imagine.
What is meant by squaring, or cubing, a number?
The square of a number is that number times itself. 5 squared, denoted 52 , is equal to 5×5 , or 25. 2 squared is 22 = 2×2 = 4 . One way to remember the term "square" is that there are two dimensions in a square (height and width) and the number being squared appears twice in the calculation. In fact, the term "square" is no coincidence--the square of a number is the area of the square with sides equal to that number.

When do engineers work with numbers?
Engineers like numbers to have units that they can keep track of properly. There's a big difference between a foot and a meter, or between a gram and a kilogram, and confusing two units can cause an engineering problem to fall apart completely.
How do you avoid making mistakes with numbers?
Careless mistakes are mistakes that we make and later realize that if we had been paying better attention to our responsibilities, the mistake may not have been made.

When do people use the scientific method?
Scientists use the scientific method because it is evidence-based, standardized and objective in conducting experiments.
Why is the scientific method important?
The scientific method is important because it is an evidence-based method for acquiring knowledge.

What are some steps in the engineering design method?
The engineering design process is a series of steps that engineers follow to come up with a solution to a problem. Many times the solution involves designing a product (like a machine or computer code) that meets certain criteria and/or accomplishes a certain task.
Why is using a design method important?
Being organized is one of the most important things for any professional especially for web designers since they have to handle a lot of things. With things not organized and messed up, a simple work can take more time than required.
