SONGS/SAYINGS
First you get sunlight from the sky;
Add water and carbon dioxide
A handful of nutrients help
They all go inside the leaf
Out comes sugar for energy
Oxygen returns to the air
And that’s how photosynthesis works
If you don’t get it you better memorize it.
The solution to pollution is dilution
Lead, follow, or get out of the way!
