If Laila weighs the salt and vinegar solution and the pennies after the experiment, what do you think she will find?

• The solution will weigh more and the pennies will weigh less after the experiment.

• The solution will weigh less and the pennies will weigh more after the experiment.

• The solution will weigh the same and the pennies will weigh the same after the experiment.

• The solution will weigh the same and the pennies will weigh less after the experiment.

The graph to the right shows how much the salt and vinegar solution weighed before the experiment. It also shows how much the pennies weighed before the experiment. Laila weighs the pennies after the experiment and finds that they weigh 8 grams. Complete the bar graph to show how much the pennies weighed and how much the salt & vinegar solution weighed after the experiment.

• The pennies weigh 8 grams and the salt & vinegar solution weighs 10 grams.

• The pennies weigh 8 grams and the salt & vinegar solution weighs 5 grams.

• The pennies weigh 8 grams and the salt & vinegar solution weighs 12 grams.

• The pennies weigh 8 grams and the salt & vinegar solution weighs 8 grams.

When baking soda mixes with vinegar in a sealed plastic bag, bubbles form and the bag expands. Why does the bag expand?

• The reaction produces a gas that increases pressure inside the bag.

• The reaction absorbs heat, causing the bag to expand.

• The reaction creates a vacuum, pulling the bag inward.

• The reaction solidifies the contents, pushing the bag outward.

If two cups of baking soda are added to the vinegar in the bag, how would that change the reaction?

• The reaction will produce more carbon dioxide gas.

• The reaction will produce less carbon dioxide gas.

• The reaction will not change.

• The reaction will stop completely.

Emi drops a cup of baking soda into a glass container that has vinegar at the bottom of it. Then, she quickly puts a balloon on top of the container. What do you predict will happen to the balloon?

• The balloon will get bigger because it will become filled with solid (baking soda) particles that are too small to be seen.

• The balloon will get bigger because it will become filled with liquid (vinegar) particles that are too small to be seen.

• The balloon will get bigger because it will become filled with gas particles that are too small to be seen.

• The balloon will stay the same because it will not become filled with anything.

If Priya only looks at the results of the Vinegar Experiment, what can she figure out?

• Either B or C is the baking soda. A must be the salt.

• Either A or B is the baking soda. C must be the salt.

• Either A or C is the baking soda. B must be the salt.

• Priya can’t figure anything out if she only looks at the Vinegar Experiment.
