T1 Assessment Quiz!

A group of students have two bottles. They fill both bottles with 30 mL of vinegar, but they only add a teaspoon of baking soda to one of the bottles. They observe the bottle with the baking soda and vinegar is filled with bubbles, while the bottle with just vinegar has no reaction. Select ONE option from each of the three sections below to complete a claim about the scenario above. Part A - Claim Which statement describes the changes that take place in this investigation?

• A. The bubbles indicate the formation of a new substance in the bottle with baking soda, while the bottle without baking soda indicates no change.

• B. The bubbles indicate a change in the shape of the liquid in the bottle with baking soda, while the bottle without baking soda indicates no change.

• C. The bubbles indicate the formation of a new substance in the bottle with baking soda, while the bottle without baking soda indicates a similar change.

• D. The bubbles indicate a change in the texture of the liquid in the bottle with baking soda, while the bottle without baking soda indicates a similar change.
