Day or Night? *
AbstractAnimals have different levels of activity depending upon their habitat, metabolism and behavior. Diurnal animals are more active during the day. Nocturnal animals are more active at night. Being diurnal or nocturnal may have different advantages for different animals. For example, desert animals tend to be nocturnal so they can stay cool and escape the desert heat present during the day. What types of diurnal and nocturnal animals are common in your area? You can set out a small trap to catch small invertebrates like insects, spiders and worms. Check your trap at the end of the day and in the morning to see which animals are diurnal, nocturnal or both. To make a recessed bug trap, dig a small hole deep enough to sink a glass jar into so that the rim of the jar is just below the surface of the soil. Cover the jar and surrounding area with a piece of wood or rock. You can also make more complicated traps to catch night flying bugs, or you can make a sweep net to catch flying bugs during the day. You can even make your own small animal traps to catch larger animals, but get your parents' help with this one as some small animals can carry rabies.

Zoologist and Wildlife BiologistEver wondered what wild animals do all day, where a certain species lives, or how to make sure a species doesn't go extinct? Zoologists and wildlife biologists tackle all these questions. They study the behaviors and habitats of wild animals, while also working to maintain healthy populations, both in the wild and in captivity. Read more
Park RangerPark rangers are the law enforcement officials of our state and national parks. They protect and preserve parklands, keeping park resources safe from people who might try to damage them, deliberately or through neglect, and keeping people safe from dangers within the park. To achieve this goal, park rangers work in a wide variety of positions, including education and interpretation for park visitors, emergency dispatch, firefighting, maintenance, law enforcement, search and rescue, and administration. There is a large global shortage of park rangers in developing countries. Read more
