Natural Selection and Gummy Bears

The video tutorial demonstrates natural selection using a classroom activity with gummy bears. Students act as predators, selecting gummy bears to eat, simulating natural selection. Over two rounds, the population of gummy bears changes, with less tasty ones surviving and reproducing. This mirrors real-world examples like the peppered moths during the Industrial Revolution. The video concludes by encouraging teachers to try this engaging activity.

What is the primary concept of natural selection?

• Natural selection decreases the diversity of traits in a population.

• Organisms with beneficial traits are more likely to survive and reproduce.

• Adaptations are not related to survival.

• All organisms in a population have identical traits.

In the gummy bear activity, what role do the students play?

• They are observers of the activity.

• They are the predators selecting gummy bears.

• They are the gummy bears.

• They are responsible for doubling the gummy bear population.

What happens to the gummy bears that are not selected by students in the first round?

• They change color.

• They double in population.

• They are removed from the activity.

• They become extinct.

Which gummy bears are most likely to survive the selection process?

• The least tasty gummy bears.

• The most colorful gummy bears.

• The largest gummy bears.

• The smallest gummy bears.

What is observed in the second round of the gummy bear activity?

• Further extinctions and population shifts.

• All gummy bears survive.

• An increase in the most tasty gummy bears.

• No changes in the gummy bear population.

How does the gummy bear activity illustrate natural selection?

• By showing that all gummy bears survive equally.

• By indicating that students prefer certain colors.

• By demonstrating that less tasty gummy bears survive better.

• By proving that gummy bears can change color.

What real-world example is used to explain natural selection?

• The migration of birds.

• The change in peppered moths during the Industrial Revolution.

• The evolution of dinosaurs.

• The adaptation of polar bears.

What caused the change in the population of peppered moths in England?

• An increase in food supply.

• A decrease in predators.

• The trees being coated with soot.

• A change in climate.

What was the adaptation that allowed some gummy bears to survive better?

• Being less tasty.

• Being more colorful.

• Being larger in size.

• Being more numerous.

What is the main lesson from the gummy bear activity?

• Natural selection favors certain traits over others.

• Students prefer certain colors of gummy bears.

• All gummy bears are equally likely to survive.

• Gummy bears can change their taste.
