This is one of my favorite projects, but it takes a long time. We focus on 'observational' drawing, and the students use detailed pictures of insects to draw their own insects focusing on the lines and little details of the insect.
Then, they color with prismacolors. We talk about blending with them, to make the insects look 3D.
Next, we create a bug jar from a separate piece of 12x18 paper. The students add detail inside the bug jar (a twig, a water bowl, a spider web, etc). Then, they cut out their bugs and glue them on. They may flip up the wings of their flying creatures and make them pop out.
Lastly, they glue their bug jar onto a 12x18 colored piece of paper, and add a table-cloth design to add detail and contrast.
Oh, and I almost forgot-add the bug jar sign on with tape, or draw it on. The sign may say various things:
"Creepy crawly bugs!"
"Beware of bugs"
"My bug jar"
"I love bugs"
"Caution: Man Eating Bugs"
(Trust me, I've seen it all!)
Have fun. (Sorry my picture isn't the best)
