Science Fair Project Idea
You have probably heard about left-brain and right-brain differences in people. The left brain is supposed to be better at language, and organizing sequential actions, the right brain is supposed to be better at visualizing orientations in space, making and listening to music, and deciphering the emotions of others. Is there evidence for left/right brain specialization in other animals? This project examines tail-wagging in dogs. Does tail-wagging show any evidence of left/right brain… Read more

Cats are great house pets, but as every cat observer knows, they are also instinctive hunters. This experiment provides an interesting way to learn about cat behavior. You'll play bird call recordings for pet cats, and watch to see if the cat pays attention to the sound (by turning towards it) or ignores it. Will a pet cat distinguish between the calls of local birds vs. non-local birds? Read more

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. Read more
