What is a one-sentence summary of the following article?
What is the objective of creating a model? Make a list of the data you want to find by using the model. It is crucial to ask this question before you create your model or you may end up creating a model that does not meet your objective. Do you want to predict something? Find out how to regulate something? Or do something else? For example, imagine you want to know how much room you have in a storage unit to see how many boxes you can put into it. You will be creating a model to predict the amount of space that is in your storage unit. What data do you already have? Make a list of the data that has been given. As you list the data, decide what pieces are most relevant and which pieces are not relevant. You should also list any information that can be assumed based on what you already know. Keep in mind that you may have to take measurements to find the data that you need. To find out how much room you have in your storage unit, you will need to measure the unit's height, width, and length. Do you need to consider factors like gravity, volume, time, etc.? Make a note of any factors that will need to be considered when you create the model. To determine the amount of space that you have in your storage unit, you will need to find the volume. You also need to keep in mind that there will be some wasted space, since some objects may be irregular and that will make it difficult to use every inch of the storage unit. What equations and formulas will you need in order to find your answer? How will you apply these equations and formulas? Make sure that you have a clear understanding of how to plug the data that you have into the equation. To find the volume of the storage unit, you will need to use the equation V= h x w x l There is no need to re-invent the wheel if somebody else has developed a model that may suit your purposes already. Check in your textbook or ask your teacher. Just remember to make sure that someone else's model will work for your situation. To get an idea of how to find the volume using the equation you have identified, check your textbook or ask your teacher. A simple mathematical model may not require a diagram. However, if you are creating a complex model, a diagram may help you determine if your model will work. Draw a diagram to represent the actual model you plan to make. Make sure to incorporate your data into your diagram to help guide you when you create the actual model.
Determine what you want to know. Determine what you already know. Determine the physical principles that govern the model you want to create. Identify the equations that you will need to use to find your answer. Look at what others have done. Create a diagram for your model.
