1. Materials per student- blank sheet of copy paper, scissors, ruler; yellow, orange, and red colored pencils (optional)
*Note- on slide 3, we’ll say the Earth is 6,000 km deep for the sake of round numbers, even though it’s a few hundred more km than that.
When scaling them (still on slide #3), you don’t need to measure all the depths with a ruler to be exact; in fact, please don’t let students try (it’ll take too long, wasting time on something that’s not that important today). As the ppt shows, get your 0 km at the top and 6,000 km at the bottom, then about halfway between will be the 3,000 km. The others you’ll get close by guestimating.
No coloring done on this graphic organizer, but it wouldn’t be difficult to have students shade from yellow to orange to red going from bottom to top (either on the outside or inside of the flaps). That would reinforce even more that in both cases we’re talking about the same earth.

2. Now cut across that line (top sheet only !)
Draw a line
2 ½ cm down

3. Earth’s Layers Physical layers-
based on physical properties (solid or liquid, how waves move though)
Compositional layers-
based on what they’re made of km
This is a close-up view of the upper half
