The Scientists of Lizard Island

In this reading, scientists learn about how scientists studied what happened when new brown anoles were introduced to an island inhabited by green anoles.

Can you do the waggle dance?

Bees live by the hundreds in hives, setting out each day in search of nectar. When a bee finds food, it heads back to the hive and tells the other bees all about it. How? By wiggling its body in patterns that tell the bees where to find the flowers.

See how good you are at dancing like a bee with this activity from the New Jersey Agricultural Society. (Grades 3–5)

Safety in numbers

• A crow on its own might make an easy meal for a big, strong bald eagle. But as you can see here, a group of crows (called a “murder” of crows) can work together to chase an eagle away. (1:23, TheLivingWilderness)

• Most big birds are not built to fight in the air. Smaller birds that can fly faster and change direction more quickly can often avoid them. Big groups of small birds can be even more effective. See how sticking together helps this huge flock of birds escape a falcon on the hunt. (2:40, BBC)

• Are killer whales really dangerous? In this mini-lesson students discover that living in a group helps young animals learn from the older members.
