Materials-
Water, pan, raw egg, cracking device like a teaspoon, and paper towels or
1. Boil the egg until all parts are cooked (about 10 minutes). Pour the water off, and allow the egg to cool, so it is COOL to the touch before you proceed.
2. Use the cracking device, once the egg is cool, and lightly tap the shell in several places so there are several large cracks in the shell resulting in several large pieces of egg shell.
3. Place the egg on a layer of paper towels or newspapers.
4. Try to move the pieces of the cracked egg shell around on the surface of the egg. (Don't remove them; just see if they slide around.) There should be slight motion allowed by the membrane holding the shell to the rest of the egg inside.
5. Find two sections of the egg that are fairly large and on opposite sides of a crack. Use your index fingers and push or pull the two sections away from each other. Observe what happens in the area of the crack between the pieces.
6. Stay in the area of the same two sections, and push the two pieces toward each other. Observe what happens in the area of the crack.
7. Stay in the same area, and try to slide one section of the shell up or away from you and pull the other down or toward you. Observe what happens in the area of the crack.
Think About This:
What you have done is a simulation of the way that the large sections of the Earth's crust, the tectonic plates, move on the earth.
thank you for showing this flvs experiment
