Transcript
- [David] Hey, wordsmiths. We've got three words to look at today. I'll define each one and then I'll use each in its own sentence. The first word is examine. Examine. It's a verb, an action word. It means to look at or study carefully. Another word for a big test is an exam, short for examination, which is the process of being examined.
When you take an exam, you're being looked at or studied carefully to see if you've learned a subject. It's funny. You study and then you get studied. Examine. Okay, next word. Resource. Resource. It's a noun, a person, place, thing, or idea. A resource is something found in nature that people can use.
A resource could be the air we breathe, the water we drink, the metals we mine from the earth. There are other kinds of resources too, like they don't always be from nature. You could use resources like your school library or the help of your friendly local librarian to do a project.
Our last word is pollution. Pollution. This is another noun, and it means the act of making the water, land, or air dirty. Smoke, smog, garbage. These are things that pollute nature, that make it dirty or make us sick. It's got that T-I-O-N ending on it, that suffix that turns verbs into nouns.
So the word pollute means to make the water, land, or air dirty, right? But if we put T-I-O-N on the end of it, it makes it into that noun, the act of dirtying nature. Pollution. Let's use these words in some sentences. Dr. Ross put the feather under a microscope to examine it more closely.
She wants to study the feather by putting it under her microscope, that tool she uses to look at objects very close up. By using the microscope, she can study the feather very carefully. She can examine it. Because trees can grow back after they're cut down, wood is a natural resource that doesn't run out.
People use trees as a resource. We use them to make things. Furniture, houses, cardboard boxes, paper airplanes. And if we're careful, we can keep growing new trees and harvesting them in a way that doesn't hurt the planet. But that's what a resource is. It's a thing that human beings use, whether they're being careful about it or not.
Here's an example of not being careful about using resources. The pollution pouring out of the factory is poisoning our river. Whatever it is that this factory makes here at Blech Industries, it also makes pollution. It pumps out something that is damaging or dirtying this river.
It's polluting it with pollution, which is gross and bad. But you know what's not gross or bad? Learning new words. Never a bad idea if you ask me. Okay. Until next time, you can learn anything. David out.
