6. David added a little baking soda to a beaker that contained vinegar. Bubbles started coming from the mixture as a gas was released.

Kim said the gas was evidence that the mixture was starting to boil.

Crystal said the gas was evidence that the air in the flask contracted.

Amanda said the gas was evidence that a chemical reaction had taken place.

Linda said the gas was evidence that the vinegar and baking soda expanded.

Who is right? ___________________

Explain how you know this person is right.

7. Austin dissolved a lot of salt in some water in a large flat dish and put the dish in bright sunlight on a hot day. What would Austin see when he returned to the dish after several hours?

Matthew stated the only thing that would be left would be dry salt.

Jonathan disagreed and said the only thing would be water with no salt.

Ben disagreed and said there would not be a change at all. The same salty water would be there when Austin came back.

Which person is right? _____________________

Explain how you know that person is right.

8. Nathan ate a hot dog for lunch. He knew that the hot dog went through some changes but wondered how he could describe them.

Jose said the hot dog went through both physical and chemical changes.

Steven said that the hot dog went through a physical change.

Adam said that the hot dog only went through a chemical change.

Which person is right? ______________________

Explain how you know that person is right.

9. When hot coffee is poured over a cup of ice, the ice begins to melt and mix with the coffee. This is considered to be a physical change. Explain why this is a physical change.

Linda said the gas was evidence that the vinegar and baking soda expanded.

Who is right? ____Amanda_______________

Explain how you know this person is right?

The mixing of baking soda & vinegar created a gas which is an indicator of a chemical reaction.

7. Austin dissolved a lot of salt in some water in a large flat dish and put the dish in bright sunlight on a hot day. What would Austin see when he returned to the dish after several hours?

Matthew stated the only thing that would be left would be dry salt.

Ben disagreed and said there would not be a change at all. The same salty water would be there when Austin came back.

Which person is right? _______Matthew______________

Explain how you know that person is right.

The water will evaporate and leave the salt behind. Adding the salt to the water did not create a chemical reaction.

8. Nathan ate a hot dog for lunch. He knew that the hot dog was went through some changes but wondered how he could describe them.

Jose said the hot dog went through both physical and chemical changes.

Steven said that the hot dog went through a physical change.

Adam said that the hot dog only went through a chemical change.

Which person is right? ___Jose___________________

Explain how you know.

The hot dog went through physical changes when he was chewing it up. Then it went through chemical changes as it passed through his stomach.

9. When hot coffee is poured over a cup of ice, the ice begins to melt and mix with the coffee. This is considered to be a physical change. Explain why this is a physical change.

This is a physical change because the water from the ice can be changed back to a solid if you freeze it again.
