7. Disappearing Ice Demonstration!
Write your prediction about what’s going to happen when a piece of dry ice and an ice cube are placed on paper plates. What could we do to make them evaporate more quickly?
At the end of class, let’s see what happened. Be ready to explain!
I can compare particles in a solid, liquid, or gas

3. Which diagram best shows the type of particle arrangement associated with a gas? a. B. C. D.
Justify your answer!
I can compare particles in a solid, liquid, or gas

11. Dry Ice Demonstration Dry Ice is Solid Carbon Dioxide (CO2).
Caution: Dry ice is very dangerous and you should always use proper safety when handling it. Always wear gloves and never keep in a closed container.
Sublimation- state in which a solid changes directly to a gas.
Let's experiment!
Analyze what happened!
I can compare particles in a solid, liquid, or gas

I can compare particles in a solid, liquid, or gas

13. Root Beer Floats: States of Matter
Measure ½ cup of root beer and pour into cup.
Next add 1 scoop of ice cream.
Slowly add more root beer to the cup and observe what happens.
What is produced? Is this a physical or chemical change?
On you chart, draw and label the solid, liquid, and gas produced when making the root beer float (ice cream, root beer, air bubbles)
I can compare particles in a solid, liquid, or gas
