OUTCOME
I will be able to convert temperatures stated in C into Kelvin, and differentiate between the terms heat and temperature
Absolute Zero,(-273 C) is the coldest temperature possible. At this temperature, atoms have the minimum amount of kinetic energy possible.
LEARNING TASKS
Explain
Where does the idea of absolute zero come from?
Explore and Elaborate
Use a temperature gun to measure the temperature of a number of different objects and surfaces inside and outside the room. What factors will affect your reading? What is the temperature gun actually detecting?
Measure some metal and some non metal in the same vicinity, now tough the two. What do you notice?
How can you explain what you feel?
What are the implications for terms like "hot" and "cold"
Evaluate
Do these questions:
