Ocean Acidification and Climate Change

The video, presented by Adam Lawson from the Ontario Science Centre, explores the concept of climate change and its impact on the planet, particularly focusing on ocean acidification. Through a simple at-home experiment using red cabbage juice, vinegar, and baking soda, viewers learn about the pH scale and how carbon dioxide affects ocean chemistry. The video discusses the negative effects of ocean acidification on marine life, such as coral bleaching and weakened shells. It concludes with practical steps individuals can take to reduce their carbon footprint and protect the environment.

What is the primary cause of climate change as discussed in the video?

• Increase in solar activity

• Volcanic eruptions

• Natural climate cycles

• Increase in greenhouse gases

How do greenhouse gases affect the Earth's temperature?

• They absorb water vapor

• They trap heat from the Sun

• They reflect sunlight away from Earth

• They cool the Earth's surface

What household item was used to demonstrate ocean acidification in the experiment?

• Red cabbage juice

• Baking powder

• Salt water

• Lemon juice

What is the role of carbon dioxide in the experiment?

• It evaporates quickly

• It forms carbonic acid

• It acts as a base

• It neutralizes the solution

What happens to marine organisms as ocean acidity increases?

• They thrive in acidic conditions

• They struggle to form strong shells

• They become more resilient

• They grow larger shells

What is the effect of ocean acidification on coral reefs?

• Coral reefs are unaffected

• Coral reefs grow faster

• Coral reefs become more colorful

• Coral reefs become stressed and bleach

Which human activity is a major contributor to carbon emissions in Ontario?

• Gasoline and diesel transportation

• Wind farming

• Solar energy production

• Hydroelectric power

What is one suggested way to reduce personal carbon emissions?

• Increase home heating

• Drive alone more often

• Use more plastic products

• Carpool or use public transportation

How can individuals contribute to protecting the oceans?

• By using more fossil fuels

• By ignoring climate change

• By supporting not-for-profit organizations

• By avoiding conversations about climate

What is a fun suggestion for altering the experiment at home?

• Perform the experiment in the dark

• Use a different color indicator

• Add eggshells to mimic sea shells

• Use lemon juice instead of vinegar
