Intro.......................................................
- by teachers prior to parents coming in.
Who knows the difference between heat and temperature?
Heat = a type of energy
Temperature = the measure of heat energy
Hold up a thermometer - How many of you know what this is? what is it used for? Has your mom ever measured your temperature when you were sick?
How can you increase the temperature of something?
Fire
Soak in the sun
- Tell the kids to rub their hands together, can they feel their hands heat up? - friction makes heat too!
Tell
them to take their warm hands, and touch something that is colder -
like the metal bar on their desk, can they warm up the bar? Heat flows from hot to cold until both objects have the same temp.
Stations!..........................................................
Short version (scroll down for long version)
***It's actually pretty hard to pop the balloons, it seems to work better to rub a balloon on the carpet, then to rub two balloons together - so just rub one balloon on the carpet - let them feel it getting warmed up before popping it - then continue to rub it on the carpet until it pops. (Adult will need to do this - you have to rub pretty hard!)
Don't actually start a fire, but you can talk about how they can!
Rub their hand on something smooth - like their desk top, and then rub their hands on something rough - like the carpet. Which generates the most friction?
Station#2 Light Energy...................................
Glow in the dark paint - Thank you Vivian!
The paint soaks up light energy, then slowly releases it in the dark.
Put the jar with paint on it into a dark box - let kids look through peep hole in the box at the glowing paint.
Station #3 Sound Energy..............................
Put water in a dish, put rubber bands around it. The sounds waves will vibrate the water, so you can see the sound in the water.
Save your oatmeal containers! You can put rice in the bottom, and watch/listen to the rice jump around from the vibrations too.

Lab #3 Oct 18th, Heating and cooling
Thank you Jennifer for putting together this lab!!!
Schedule - same as last time, let me know if you can't make it!

Popcorn will be an entire class activity - make popcorn in front of class, then pass it out, they eat while watching popcorn movie - then split into 2 groups for remaining stations.

**New this time*** - Teachers will do the intro before we get there, so we can jump straight into the stations - this will give all of us more time at the stations (less rushed) and the teachers will make sure the kids are learning what they are supposed to be learning ;)
Intro: By teachers
Heating and cooling can change matter.
Heat an ice cube - get water, water to steam etc.
Heat air - the air expands.
Have you ever cooked food with your mom in the kitchen? What happens when we heat food up? Pasta noodles get soft, etc.
Entire Class: Why does popcorn pop?
Lab stations
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Station #1: Making it rain
Explanation: The air inside the jar becomes
warmer as it mixes with some of the hot water.
This forms water vapor, which is a gas, or air mixed with water
molecules. When the molecules warm, they
rise in the jar, just like they do in the atmosphere. When the plate cools from the ice cubes, the
warm water vapor bumps into it and cools off.
When the water vapor cools, it turns back into tiny drops of water,
called condensation. This is what makes
rain.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Station #2: Warm Air needs more room
Supplies needed:
Activity:
Talking points to be shared with students:
· Warm air expands
· Molecules in the warm air move very fast and far apart from each other, taking up more space than when they were cold and stayed close together.
Schedule - same as last time, let me know if you can't make it!

Entire Class: Why does popcorn pop?
Supplies needed:
- Popcorn kernelsPopcorn popper (2) (I have one to use)Vegetable oilSaltNapkins
Explanation:
Each kernel of popcorn contains a small drop of water stored
inside a circle of soft starch. Popcorn needs between 13.5-14% moisture to
pop. The soft starch is surrounded by the kernel's hard outer surface.
As the kernel heats up, the water
begins to expand. Around 212 degrees the water turns into steam and
changes the starch inside each kernel into a super-hot gelatinous goop.
The kernel continues to heat to about 347 degrees. The pressure inside
the grain will reach 135 pounds per square inch before finally bursting the
hull open.
As it explodes, steam inside the
kernel is released. The soft starch inside the popcorn becomes inflated
and spills out, cooling immediately and forming into the odd shape we know and
love. A kernel will swell 40-50 times its original size!
Kids get to eat the popcorn after
it pops!
Talking points to be shared with
the students:
- · When matter is heated it expands.· Heating the popcorn kernel causes the water inside to expand.· The water expands until it gets so big it explodes.

Lab stations
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Station #1: Making it rain
Supplies needed:
- Glass jarPlateHot waterIce cubes
Activity:
- Fill the jar with about two inches of very hot water. Cover the jar with the plate.
- Wait 2-3 minutes before the next step.
- Place ice cubes on the plate.
Talking points to be shared
with the students:
· When water is heated, water vapor is created
(change from a liquid to a gas)
· When the water vapor (gas) meets cold, tiny
drops of water are formed.
· Rain happens when warm air rises through the
atmosphere and meets cold air.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Station #2: Warm Air needs more room
Supplies needed:
- Balloon
- Empty glass bottle (with mouth small enough for balloon to fit over)
- Pan with hot water
Activity:
- Stretch the balloon over the mouth of the bottle.
- Place the bottle in the warm water (not boiling).
- The balloon will begin to inflate as the air inside the balloon warms and expands. Molecules in the warm air begin to move faster and further apart from each other, making the balloon stretch.
- The amount of air has stayed the same, but it has expanded and now takes up more space.
Talking points to be shared with students:
· Warm air expands
· Molecules in the warm air move very fast and far apart from each other, taking up more space than when they were cold and stayed close together.
