Question: Do CO₂ emissions affect global warming?

Study the following source: How Carbon Affects Nearly Everything on Earth – Including Our Future

Scientific source: Conducting an experiment

Follow the guidelines of the experimental procedure to answer the question: Does rising CO₂ affect the Earth's temperature?

ENGLISH MISSING ------------------------ NB! Acid + Carbonate → happejääk + H₂O + CO₂

Tools and materials:

  • Two bulbs
  • Two electric thermometers
  • Two glass bottles with caps
  • Two paper rolls
  • Baking soda
  • Vinegar
  • Funnel
  • Volumetric cylinder
  • Plastic container
  • Spoon
  • Pair of scissors
  • Tape

Experimental procedure:

  1. Place the thermometer cable into the paper cylinder.
  2. Put three tablespoons of baking soda in the two glass bottles.
  3. In a volumetric cylinder, measure 50 mL of vinegar.
  4. Stick the paper cylinder with its thermometer in each glass bottle.
  5. In a container, pour the vinegar with the help of the funnel and close the lid. At the moment, we close the lid on the 2nd container.
  6. Leave a light bulb next to each container for 30 minutes. During this time, we monitor the change in temperature in each case and record our data.
