The presentation starts with a demonstration of radiant heat. This didn't go very well. You are supposed to compare the direct heat given off by a long kitchen match to that of a spoon heated on a hot plate. I'm lazy so we compared the direct heat given off by our gas burner to the radiant heat given off by a spoon heated by the same gas burner. I don't know if something is wrong with our spoons or what, but there wasn't a whole lot of radiant heat given off. All three of us burned ourselves on that spoon while trying to get close enough to feel it. We need do heat something else. Like a brick. I don't particularly want to heat a brick. I'm open to suggestions.
Also, this is why you are supposed to practice your presentations before giving them to the kids. So lazy. Also, this is why experienced teachers are worth more money than newbies. Just saying...
As always, the ETC charts are prettier, but don't illustrate the concepts as clearly.
I like that it is nighttime in the second Albanesi-style chart.
None of my resources explain what the little circles are on the charts. I assume they are particles of gas in the atmosphere. If that is the case, I wish the Albanesi-style charts had done a better job of thinning them out a little in the middle layers and I wish that the ETC charts hadn't made such a clean straight line of them at the bottom.
Anyway, once the child understands that heat not only comes directly from the sun but is also radiated from the Earth and that this radiated heat is often trapped by the particles of gases in the atmosphere (apparently it's like some cities in the U.S., getting in is just fine but getting out can be a nightmare) we move on to the "blanket" charts. The baby at the top of the mountain not only has less/no blankets but also cannot feel the radiant heat from the Earth at the bottom of the mountain. My kids were mostly concerned that a baby was up that high on a mountain and wondered how it got there.
The second baby has more blankets of the atmosphere and is also benefitting from radiant heat at ground level. The boys felt this baby was safer, but worried about predators.
This ground-level radiant heat is represented by an Ewok-style roasting of the person in the Albanesi-style chart. Maybe this is why they chose NOT to use a baby in these charts.
That looks more like direct heat than radiant heat to me...
