Outcomes
(what you should know) || ==Resources== || ==Homework== || ==Deadline== || Temperature scales and units: fixed points, celsius, fahrenheit, kelvin || * understand that heat and temperature are different concepts, and give examples that show you can explain the difference 117-122 ||  ||   || Good and poor examples of heat transfer in each method. || * Know that there are three methods in which heat moves – conduction, convection and radiation Make brief notes with explanations (use the ideas of conduction, convection and radiation) || For next lesson (Monday) ||
 * 1 2/1/13 || Heat and temperature - what are they
 * use the celsius and kelvin temperature scales
 * construct a temperature scale using fixed points
 * convert between different temperature scales
 * || Ilmiö p.85-88;
 * 2 7/1/13 || Heat transfer mechanisms: conduction, convection, radiation - what they are on the particle level and where they can occur.
 * identify what factors are needed for heat transfer by each different method
 * identify the main heat transfer methods in different situations || [[image:heat transfer venn diagram.png width="298" height="221"]] || How do the following animals keep warm or cool, as necessary ?
 * 3 14/1/13 || 'Which way should you wear fur?' investigation

First we take results from the cooling water experiment with three different conditions (video). Discuss whether the results agree with the theory. Then the investigation will be introduced and apparatus demonstrated || * analyse experimental data from heat transfer experiments Thermal image of zebra
 * recall that black, dull surfaces are better heat radiators and absorbers than white, shiny surfaces
 * critically evaluate experimental results in terms of reliability, accuracy and validity || Youtube video (not a public link)

Experiment instruction sheet

Experiment report sheet - please note you are welcome to do this electronically || Monday homework - complete graph plotting from lesson and answer 'does this data agree with the theory we wrote?'

Planning/research/writing up the investigation || For next lesson ie 9A Tuesday 9B Friday ||
 * 4 21/1/13 || 'Which way should you wear fur?' investigation || See above || See above

Hints for the data:

1. you MUST show all your results - try to display them on one table with many columns (all correctly labelled of course!)

2. for your graph(s) try to show fur in/fur out on the same graph., However you may end up wit two graphs (1st try, 2nd try) - that is better than averaging results as the conditions under which you did the experiment may not be the same. || Planning/research/writing up the investigation
