It's asking you to write about a grasshopper or another insect using as many of the spelling words as possible.
I'll write an example for you using the grasshopper, but you'll still have to do one of your own for the homework. Spelling words will be bold.

Grasshoppers are small insects, whose camouflage makes seeing them scarce. They specialize in making loud chirping noises and eating crops. The ridges on their back legs enables them to make the chirping noises. In critical situations, they spit a brownish mucus-like substance from their mouths to gross out whatever is threatening them. Because they're outside, they're not very sterile, so be sure to wash your hands if you touch one.
