What's Going On Behind Those Puppy-Dog Eyes?

Science Fair Project Idea

Scientific Method

Have you ever wondered what goes on in your dog's mind? Even though humans have the benefit of language, trying to understand another person's thoughts can be hard enough sometimes. Your dog can't talk, so how can you find out what its brain is capable of? The obvious answer is to study its behavior. This project will show you some behavioral tests you can use to measure canine I.Q. Read more

Does Sense of Touch Impact a Cat's Behavior?

Science Fair Project Idea

Scientific Method

Have you ever seen a cat slowly move its head and whiskers into a small space before crawling through it? They’re using their sense of touch to see if they can fit into the space! In this science experiment, you’ll test how cats use their sense of touch to move through the world by using a maze to determine if they prefer big or small spaces. Read more

Eeew, Dog Breath! Does Active Play Take Your Dog's Breath Away?

Science Fair Project Idea

Scientific Method

When you're chasing after your dog, do you ever stop and say, "Wait, I have to catch my breath!"? Do you think that there are times when your dog feels like that, too?

X-inactivation Marks the Spot for Cat Coat Color

Science Fair Project Idea

Scientific Method

Have you ever seen a tortoiseshell cat? "What kind of cat is that?" you might ask. A tortoiseshell cat has two different fur colors, black or brown and red or orange. The gene that gives rise to the red or orange fur color is on the X chromosome. And did you know that most tortoiseshell cats are female? That's because female cats have two X chromosomes, while males only have one, which allows the females to express two different color combinations! Try this science fair project to figure out… Read more

Is That Cat Overweight?

Science Fair Project Idea

Scientific Method

Did you know that there are millions of overweight cats and dogs in the United States? Is your pet one of them? How about your neighbor's cat or your grandma's dog? In this science project you'll determine what percentage of the pets you know are overweight and how their weights compare to pets' weights throughout the United States. Read more

How Do Cats Respond to Bird Sound Recordings?

Science Fair Project Idea

Scientific Method

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

Seems that dogs, like people, have definite preferences for their play things. This fun project investigates what makes a toy interesting to a dog. In these experiments, you and your dog can have some fun while you learn about canine behavior… Read more

Watch Out! That Wild Animal Might Be Rabid!

Science Fair Project Idea

Scientific Method

The word rabid often makes people think of an animal that is extremely violent, crazy, and maybe even foaming at the mouth. But not all animals infected with the rabies disease fit that description. Nevertheless, it is important to avoid animals that have rabies so that you don't get infected. So which wild animals are likely to carry rabies?

The great majority of people have a distinct hand preference. How about animals like dogs or cats? Do they show a paw preference? If you like animals, this science fair project might be for you. Read more

Puppy Proportions: Comparing Growth Spurts and Weight Gain in Your Dog's Early Months

Science Fair Project Idea

Scientific Method

Planning on getting a new puppy soon? Why not use some of your play time with puppy to study growth rates and puppy development? You can easily chart a young puppy's weekly weight and growth over several months to compare how quickly body dimensions and bone lengths change. While this project may take some time, it's well worth the effort. You might be amazed at the dramatic growth of your "canine kid," and what other project combines science with as much fun, or a more adorable subject? Read more
