Two flasks hold colored water, one yellow and the other blue. Set the starting temperature of each flask, choose a type of material to connect the flasks, and see how quickly the flasks heat up or cool down. The flasks can be connected with a hollow pipe, allowing the water in the flasks to mix, or a solid chunk that transfers heat but prevents mixing.
Experiment: Experiment with all six solid chunks.
For each, click Fast forward and then, after about 500 seconds, Pause ( ). Record the temperature of each flask.
Sort the items you tested above into the categories listed below.
Gold
Rubber
Copper
Lead
Stone
Glass
Great Heat Conductor (2)
Okay Heat Conductor (2)
Poor Heat Conductor (2)
What do good heat conductors (from our experiment at least) have in comon with each other?
Experiment: Experiment with all six hollow pipes.
For each, click Fast forward and then, after about 500 seconds, Pause ( ). Record the temperature of each flask.
Why is the transfer of heat differnet with the hollow pipe depending on if the hotter liquid is on the top vs it on the bottom?
Of the 3 things we tested, rank them form the quickest from of heat tranfer (at the top) to the slowes)
Convection (when the hottest item is on the top)
Convection (when hottest item is in the bottom)

Use a powerful flashlight to pop a kernel of popcorn. A lens focuses light on the kernel. The temperature of the filament and the distance between the flashlight and lens can be changed. Several obstacles can be placed between the flashlight and the popcorn.
We are going to compare Temperatures and see how long it takes to have the popcorn kernel pop
Distance to Lens: 60 cm
Obstacle: None
We are going to compare obstacles and see how long it takes to have the popcorn kernel pop
Temperature: 1,500 Kalvin
Distance to Lens: 60 cm
*There will be one answer that is "Never"
We are going to compare distances and see how long it takes to have the popcorn kernel pop
Temperature: 1,500 Kalvin
Obstacle: None
