Greenhouse Effect Experiment Questions

Ethan Wiles guides viewers through Experiment 2.3, demonstrating the greenhouse effect of carbon dioxide. The experiment involves measuring temperature changes in a Ziploc bag filled with air and then with carbon dioxide, using sunlight as the energy source. Required materials include a thermometer, Ziploc bag, vinegar, baking soda, and safety gear. The process involves inflating a bag with air, measuring temperature, then repeating with CO2 generated from vinegar and baking soda. The experiment illustrates how CO2 traps heat, simulating the greenhouse effect.

What is the primary role of carbon dioxide in the greenhouse effect?

• It cools the Earth's surface.

• It traps energy in the form of light.

• It reflects sunlight.

• It absorbs water vapor.

Which of the following is NOT a required material for the experiment?

• A large clear plastic bag

• A metal container

• Vinegar

• A thermometer

What safety equipment is recommended for this experiment?

• A face mask

• A lab coat

• Safety glasses or goggles

• Gloves

What should you do if the day is not sunny when you plan to conduct the experiment?

• Use a lamp as a substitute

• Wait until a sunny day

• Proceed with the experiment indoors

• Use a flashlight

What is the purpose of inflating the plastic bag with air in the initial setup?

• To test the bag's durability

• To measure the air pressure

• To simulate the greenhouse effect

• To create a vacuum

How is carbon dioxide generated in the experiment?

• By dissolving salt in water

• By burning wood

• By mixing vinegar and baking soda

• By heating water

What should you do after the bubbling of the vinegar and baking soda mixture slows down?

• Add more vinegar

• Shake the bottle

• Seal the bag with the thermometer inside

• Remove the thermometer

What is the expected temperature change in the bag with carbon dioxide compared to the initial setup?

• It should decrease

• It should remain the same

• It should increase

• It should fluctuate

Why is it important to place the bag in the same position during both parts of the experiment?

• To avoid wind interference

• To ensure consistent sunlight exposure

• To prevent the bag from falling

• To keep the thermometer stable

What is the significance of writing down the temperature readings during the experiment?

• To ensure the thermometer is working

• To compare with other experiments

• To track the progress of the experiment

• To calculate the average temperature
