Do Milkweed Bugs Show a Color Preference for Egg-Laying Sites?
Milkweed bugs, as their name suggests, have a close relationship with the milkweed plant. The plant produces an irritating, milky sap, and toxic compounds, but somehow the milkweed bug is unaffected by them. Instead, it concentrates chemicals from the sap in its body, acquiring an unsavory taste that, along with its bright coloration, protects it from predators. Given this close relationship, will the milkweed bug exhibit a color preference for egg-laying sites? This project is designed to find out.

What Seeds Do Birds Prefer to Eat?
Are you curious about the birds that live in your neighborhood? Would you like to find out more about them: what they look like close up, what they eat, how they sing? In this project you'll build a bird feeding platform with four separate feeding areas. You'll be able to observe birds at close range, find out what birds inhabit your area, and learn about their seed-eating preferences. So get out your woodworking tools and binoculars, and get ready to see some birds.
