Wednesday: Finding Food and Keeping Warm

A line of ants marches across the sidewalk toward a dropped cracker.

Rocket crouches. "How did they all find it? Did one ant yell?"

Raven traces the line with her finger, not touching. "Look. They follow the exact same path."

Nova projects a faint cyan trail over the ants. "Ants cannot yell," she says.

"But the first ant left something behind. What could another ant follow?"

More searchers

Food is hard to find. A group has more searchers, so food is found sooner.

When one ant finds food, it walks home. On the way, it leaves a scent trail.

Other ants smell the trail and follow it straight to the food.

Soon a whole line of ants carries pieces back to the colony.

Honeybees share food too. Bees store nectar as honey inside the hive.

The whole colony eats from that store when flowers are gone.

A flock finds food faster for a simple reason. Many birds search many places at once.

Warmer together

On cold nights, some small birds press close together on a branch.

Each body warms the one next to it. Less heat is lost to the air.

Honeybees do something like this inside the hive in winter.

They crowd together and shiver their muscles to make heat.

A bee alone could not keep warm. Thousands of bees together can.

FOOD AND WARMTH CHECK
  • Read the question.
  • Tap your answer.
How do ants show other ants the way to food?
Why does a flock find food faster than one bird?
How do honeybees stay warm in winter?
An ant follows a ____ trail left by another ant.
Bees store nectar as ____ for the whole colony.
Small birds press ____ on a branch to keep warm.
StatementTrue or false?
Ants find food by following a scent trail.?
A bee alone can keep as warm as a whole hive.?
Honeybees store food that the whole colony can eat.?
A flock finds food more slowly than one bird.?
WHY THIS EXERCISEGroups find food sooner, share it, and keep each other warm.
FROM ONE ANT TO A FEAST
  • ?The colony shares the food.
  • ?A line of ants follows it to the food.
  • ?One ant finds food.
  • ?Other ants smell the trail.
  • ?It walks home, leaving a scent trail.
WHY THIS EXERCISEOne finder plus a trail turns into food for the whole colony.
What do honeybees make from nectar and store in the hive?
WHY THIS EXERCISEStored honey feeds the whole colony when flowers are gone.
Try it
Find an ant trail on a sidewalk or wall with a grown-up.
Watch for two minutes. Do the ants follow the same line?
Count how many ants pass one spot in thirty seconds.
Safety first
Watch ants with your eyes only. Some ants bite or sting.
Never put a hand or a stick in an anthill or near a hive.
Stay with your grown-up and wash your hands afterward.
Draw an ant trail from the nest to a dropped crumb. Show the scent trail as a dotted line.

Well tracked, explorer! Tomorrow we peek inside a colony to see who does which job.
