Natural Selection and Ocean Acidification

The video tutorial focuses on natural selection with an emphasis on ocean acidification's impact on clams. Students engage in a hands-on activity using candy to simulate clams, observing differences in shell thickness. They conduct experiments to determine which species are more likely to survive in acidic environments. The activity highlights the benefits of thicker shells in predator-heavy and acidified habitats, illustrating natural selection principles.

What is the main focus of the activity discussed in the video?

• The role of predators in the ecosystem

• The migration patterns of birds

• Natural selection and ocean acidification's effect on clams

• The impact of climate change on forests

What do the candies represent in the activity?

• Various bird species

• Different types of fish

• Types of ocean plants

• Different clam species

Which candy has a thicker outer coating?

• Skittles

• Jelly Beans

• M&Ms

• Reese's Pieces

What is the purpose of crushing the candies in the activity?

• To determine the candy's nutritional value

• To test their flavor

• To simulate the effect of ocean acidification on clam shells

• To see which candy is more colorful

What is recorded during the tests and simulations?

• The weight of each candy

• The color of the candies

• The number of candies in each bag

• Which species survives in each test

Which species is predicted to survive better in an acidified ocean environment?

• The species that is larger in size

• The species that is more colorful

• The species with a thicker shell

• The species with a thinner shell

Why might predators prefer clams with thinner shells?

• They are more colorful

• They are more nutritious

• They are larger in size

• They are easier to break open

What is the main benefit of having a thicker shell for clams?

• It helps them float better

• It makes them more colorful

• It provides better protection against predators and acidification

• It allows them to move faster

What is the main theme of the activity discussed in the video?

• The role of natural selection in survival

• The migration patterns of marine animals

• The importance of biodiversity

• The impact of pollution on marine life

How does ocean acidification affect clam shells?

• It makes them more colorful

• It makes them more buoyant

• It causes them to grow larger

• It leads to faster deterioration of thinner shells
