NASA Connect segment explaining the mathematical standard of representation. The video gives examples and explores the purpose of representation.
Thanks, Dr. Avery. Okay, guys, let's review.
00:00:00
So far, we introduced a new approach to understanding how the Earth works, called Earth System Science.
00:00:05
Next, we defined what a system is and how the Earth system is composed of spheres.
00:00:12
Now it's time for you to become an Earth System Scientist and apply what you've learned about systems.
00:00:18
But before we begin the activity, let's review an important mathematical standard called representation.
00:00:24
Representation is central to the study of mathematics.
00:00:31
Basically, representations help you communicate your thinking.
00:00:35
Some examples of representations include drawings, charts, graphs, symbols, and physical objects.
00:00:40
By creating, comparing, and using various types of representations,
00:00:48
you can develop and deepen your understanding of mathematical concepts and relationships.
00:00:53
Earth System Scientists are constantly looking for patterns that can help them understand how the Earth works.
00:00:59
By analyzing data, they can construct relationships among numbers and the scientific principles they are investigating.
00:01:06
Often, scientists will present the relationships through some form of visual or graphical representation.
00:01:13
Now that you understand the importance of representation,
00:01:20
the students at Great Neck Middle School, right here in Virginia Beach, will show you this program's activity.
00:01:23
It involves system diagrams.
