13 ) Use models (e.g., diagrams, maps, globes, digital representations) to explain how the rotation of Earth and unequal heating of its surface create patterns of atmospheric and oceanic circulation that determine regional climates.

a. Use experiments to investigate how energy from the sun is distributed between Earth's surface and its atmosphere by convection and radiation (e.g., warmer water in a pan rising as cooler water sinks, warming one's hands by a campfire).

[SC2015] PHYS (9-12) 7 :

7 ) Plan and carry out investigations to provide evidence that the first and second laws of thermodynamics relate work and heat transfers to the change in internal energy of a system with limits on the ability to do useful work (e.g., heat engine transforming heat at high temperature into mechanical energy and low-temperature waste heat, refrigerator absorbing heat from the cold reservoir and giving off heat to the hot reservoir with work being done).

a. Develop models to illustrate methods of heat transfer by conduction (e.g., an ice cube in water), convection (e.g., currents that transfer heat from the interior up to the surface), and radiation (e.g., an object in sunlight).

b. Engage in argument from evidence regarding how the second law of thermodynamics applies to the entropy of open and closed systems.

Through the use of an experiment, PBS Learning Media videos, and interactives, students will learn how heat is transferred through convection, radiation, and conduction. Students will develop a model to demonstrate their understanding of conduction, convection, and radiation.

How do we map out a planet without oceans? There's some tricky, yet fascinating science behind all of it. In this episode of Crash Course Physics, Dr. Shini talks to us about sea level, kinetic theory, and phase changes.

Have you ever wondered why we wear clothes? I mean, beyond the obvious. Why does wearing a jacket in the cold keep you warmer? What is happening to all the heat inside your body? In this episode of Crash Course Physics, Dr. Shini talks about the physics of heat.

Have you ever heard of a perpetual motion machine? More to the point, have you ever heard of why perpetual motion machines are impossible? In this video, Dr. Shini discusses the first law of thermodynamics.

One of the greatest inventions is the steam engine. But why? What makes it so useful? And how does it work? In this episode of Crash Course Physics, Dr. Shini talks to us about how engines work, what makes them efficient, and why they're pretty cool.
