What to Do About Unknown Science Terms

You shouldn’t be intimidated if you see unknown terms.

One thing to bear in mind is the fact that often when you see complicated terms in the GED® Science test, these terms are not really important.

To give you an example, if you see complicated unit names that are used in charts, be sure they are in no way important.

What really matters is that you are able to read the charts and that you can find the right answer or solution to the question. But often, test-takers will be intimidated by some unknown terms and consequently say:

“OMG, I have no idea what that expression or word means. And therefore, I won’t be able to comprehend the passage.”

Well, here is some great news: Not one of the GED test-takers knows what those expressions or that word mean unless they are scientists working specifically in that domain.

So probably you, like the other students, don’t know what that particular unit of measure is, and you really shouldn’t be intimidated by that word or those terms.

If you come across an unfamiliar expression or term, you might as well get all excited because you’ll know that the question will be easy to answer and that it will be easy for you to spot that term or word in the table or chart.

Let’s take a look at the following question:
It reads: According to figure 2:

in case the trend in CH4 concentration would have continued to match that same trend in the intensity of solar radiation, the concentration of CH4 at present would be, most likely:
a. less than 550 PPB
b. between 550 PPB – 600 PPB
c. between 600 PPB – 650 PPB
d. greater than 650 PBB

Well, PBB is defined actually with a tiny asterisk, but that’s irrelevant.
Right here, we have no need to know or understand what PBB stands for or means.

We don’t need to have knowledge of what CH4 concentration means or what it is.
And to be honest; we even do not need to understand or know what exactly is Earth’s atmosphere.

None of those things matter.
What does matter is that we understand that it says: Go to figure 2.

So when we go to Figure 2, we know what we’re looking for, that’s concentration.
This where that word appears, whatever it is or means. I will be reading the chart. There’s no need to use these expressions and words but as signposts. And yes, I can already see the right answer to this question.
The correct answer is F, less than 550 ppb (I have still no idea what that ppb is).

So bear this in mind. The GED Science test will not be assessing if you command vocabulary.

Vocabulary may be a great help to make you feel that you’re in territory that’s familiar. But the thing that really matters is: how well are you able to digest the presented scientific information.

So, become really good at interpreting and reading tables and charts and tables. Then you’ll be absolutely fine.
