The ingredient that made bubbles or gas in more than one experiment
What is baking soda?
Did the solar oven use hot or cold energy?
Hot energy.
Do oil and water mix together?
No
The experiment that needed to be moved or shaken to work
What is ice cream in a bag?

It cooked and puffed up.
The tool that helped us measure ingredients correctly
Was ice cream made using warm air or cold temperatures?
Cold
Name two layers of the rainbow in a jar.
What is honey, dish soap, water, olive oil, and rubbing alcohol.
The experiment that used both oil and water to make movement
What is lava lamps?
What happened when we added salt to ice during the ice cream experiment?

To reflect heat/keep heat inside.
Why did the state of the pancake batter change on the hot griddle?
Heat cooks food.
Why did the rainbow in a jar layers stay separated instead of mixing?

What happened over several days to the sugar in the rock candy jars?

What is salt, baking soda, or vinegar.
If we tried to make ice cream without salt, what would happen?
It would freeze slower or not very well.
Name one experiment where mixing caused a change and explain the change.
Pancakes - heat caused bubbles to form
Ice cream - cold temperature caused liquid to freeze
Balloons - gas formed
