TOEFL Listening The Flight of the Bumblebee

The similarity between the fluid dynamics of a bumblebee and an airplane

An experiment designed to find how bumblebees detect the closest nectar

How the bumblebee flies

When bumblebees go to forage nectar

A bumblebee and an airplane use the same fluid dynamics.

A bumblebee glides through the air and doesn’t flap its wings.

An airplane’s wing forces the air down, which pushes the wing upward.

A bumblebee’s wing forces the air down, which pushes the wing upward.

How bumblebees actually fly

How much energy bumblebees exert

How bumblebees know it’s time to forage

Why bumblebees fly from flower to flower

The flowers were a variety of colors.

The motion-triggered Webcam was attached to each flower.

The scientists physically observed the bees for the entire time.

Each flower had a landing platform and a single drop of sucrose.

Bees only visited the flowers that were nearby their bee nests.

Bees traveled far to visit flowers and ignored the flowers nearby their nests.

The bees always traveled together when looking for nectar.

Bees visited flowers closest to their bee nests before going farther away.

Bumblebees pick the most efficient path to look for nectar.

Bumblebees try out different colored flowers to see the variety of tastes in the nectar.

The bumblebees take turns foraging with a buddy and if they get along, they continue.

Bumblebees leave their nests to forage at different times each day.
