200 ppm means there are 200 tiny pieces in a million big pieces, like when you mix a few drops of juice into a huge lake.
Imagine a Huge Jar of Marbles
Think about a giant jar filled with 1,000,000 marbles, that’s one million marbles! If we add just 200 more tiny marbles to the mix, those 200 would be 200 ppm. It's like adding just a few extra candies into a huge bag of popcorn, you can’t see them at first, but they’re there.
Like Sugar in Water
Now think about water. If you put a tiny bit of sugar into a whole pitcher of water, it’s hard to see or taste the difference right away, that's 200 ppm in action! It’s like if you had 200 sugar grains hidden inside a million water drops.
You might not notice them at first, but they're there, just like your favorite snacks are hiding in the lunch bag, you know they’re there, even if you can’t see them yet.
Examples
- Imagine a swimming pool with 200 grains of sand in it, that's how much carbon dioxide is in the atmosphere at 200 ppm.
- If you have 1 million jellybeans, 200 of them are red, this is like 200 ppm.
- A cup of tea has about 200 drops of water per million, that’s 200 ppm.
