Activity

  • Dance Like a Bee: 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.

  • Watch this video (2:49) to see a bee’s “waggle dance,” and then see how good you are at dancing like a bee with this activity from the New Jersey Agricultural Society. (Grades 3–5)

Reading: Ants to the Rescue!

Readings from Newselaare free with registration. They’re available in English or Spanish and can be adjusted for reading level. Writing prompts and quiz questions are available for many readings.

  • Most insects don’t help each other if they get into trouble. Matabele ants from Africa, though, are different. They’ve developed a way to get rescued if they’re hurt. Read about how they work together in this article. (Grade 3)

Video: 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)

Activity Prep

In this Mystery, students discover why dogs’ expressions, like tail wagging, are so useful when living in a pack. In the activity, Field Journal, students watch videos of different animals that live in groups to simulate observing them in their natural habitats. They discuss and record their observations, and construct an explanation of how living in groups helps these animals survive.

Prep Instructions

We suggest students work in table groups of four and share a stapler to construct their Field Journals. Homeschool students can work on their own.

The page numbers of the Field Journal will look scrambled on the printout, but when students fold them and make their booklets, the pages will be in order.
