Note from the author:

To take care of injuries, athletes often use plastic wrap to attach bags of ice cubes directly on top of their skin for 20 minutes a day after a practice or a workout. See the image for an example.

Someone got hurt and used an ice pack. Part of the way through the 20 minutes, the ice begins to melt and drip. 

Two athletic trainers, Steve and Sophie, were wondering, how does an ice work to cool down the skin and muscles? They collected some data, shown in the table below.

Two athletic trainers, Steve and Sophie, were wondering, how does an ice work to cool down the skin and muscles? They collected some data, shown in the table below.

Required

The ice is a system and the person’s ankle is another system. Energy is transferred between the two systems. Mr. Santil and Mr. Danford argued over the data about how the systems (ice pack and skin) work.
Here is what they said:
Mr. Santil: Cold moves from the ice to the skin
Mr. Danford: Heat moves from the skin into the ice
Who do you think is correct, Mr. Santil or Mr. Danford?

Required

There are two systems. The skin and the Ice pack. What part of the systems do the data tables not show that would help you decide if Mr. Santil or Mr. Danford is right?

Required

Draw a model zooming in at the point where the ice pack and skin touch. It should explain how the contact between the ice pack and skin causes the skin to cool down and/or causes the ice to warm up and melt. In your model, make sure to include these parts:
particles for the ice
particles for the skin,
how the particles move (FAST OR SLOW) in each system based on their temperatures
show which direction energy is moving (from hot object to cold objects or cold objects to hot objects)
You may use words to explain your ideas underneath your models.

Required

Change your model to show what would be different after 20 minutes.
In your model, include these parts:
particles for the ice pack
particles for the bag
particles for the skin,
how the particles move (FAST OR SLOW) in each system based on their temperatures, and
how energy is entering or leaving the systems.

Required

How would your model change if the athlete were standing outside in the sun on a hot (100℉) day?

(If it were a hot (100℉) day, the model would _________.)
