  Animal behavior projects are wise ways to explore and understand the lives of alternative species. Many animal behavior projects are available for mammals, fish, reptiles and insects. Amphibian behavior projects might test the height and length of a frog's hop, while arachnid projects can examine the strength of a spider web. Animal projects can be useful studies for children and adults alike.
  
  

Temperature Tests

• One way to examine cold-blooded creatures -- such as crickets -- is through temperature inclination. According to the Science Projects website, take a long strand of sheet metal approximately one centimeter deep and place a hot and cold substance under opposite ends. Use a controllable flame or an electric hot plate for the hot substance and a block of ice for the cold substance. After a few moments, place the cricket at the center of the metal sheet. As the substances transfer heat and cold into the metal, observe how and where the crickets move in reaction to the temperature variations. This project helps testers determine what kinds of temperatures cold-blooded creatures prefer.
  
  

A Cat's Favorite Food

• Observe and analyze how cats eat by placing bowls of food in different locations. According to Science Projects, you can test what foods a cat prefers by placing identically sized bowls of food next to each other on the floor. Make each type of food different. Once the cat decides, take the bowls and place them at alternate distances from each other. This project can provide data on how a cat behaves when examining the food. Additionally, testers can determine if the cat partakes of whatever food is closest or is more discriminate in its food selection.
  
  

Environmental Projects

• Test environmental preferences of bugs and small animals with a few simple devices. Choose a cage with multiple compartments and establish various environmental characteristics within these compartments, recommends Science Projects. Use a handful of armadilidium vulgare -- or "pill bugs" -- as test subjects. Once the compartments are ready, place the insects into the cage to identify how the bugs behave under the various conditions. Keep one area of the cage filled with light, while keeping another dark. Another idea is to maintain dry conditions in one compartment and moist conditions -- via moist soil -- in another. Spend several days or a week allowing the insects to adapt to the conditions and note how they react both individually and as a group.
