Explain what happened in the experiment when we added all the materials. What is the result of the experiment? What causes the balloon to inflate?
To get full credit do the following:
1. Restate the question.
2. Narrate the process of the experiment.
3. State that a chemical reaction occurred to produce these new substances. What was the result of the experiment?
4. Be sure to state what gas caused the balloon to inflate.
Using the formulas above explain the experiment. What happened in the experiment? What new substances were formed? Where did the different atoms and molecules start out and where did they end up by the end of the experiment?
To get full credit do the following:
1. Restate the question.
2. List the substances the experiment started with and then list the new substances that were formed after the chemical reaction.
3. State that a chemical reaction occurred to produce these new substances by explaining where some of the atoms and molecules ended up after the chemical reaction.
4. Be sure to use the formulas to explain how matter is never destroyed, but can become something new.
Be sure to describe the atoms and molecules in how they move in each state of matter.
