Q&A for How to Create a School Project on the Layers of the Earth

You could bake different colored layers of cake in small round pans and then stack them on top of each other like you would with a regular cake. You can then take toothpicks with small signs on them describing the layers of the earth and stick them through the side of the cake into each corresponding layer.

Cut out some thin strips of paper. Wrap part of it around a toothpick (leave enough room to write your label on) and fasten it with tape.

If it is hollow, no, you can't, but if it is solid, you can, just paint the layers inside the ball.

After painting the ball, cut it into halves, and, in between, place a compact disc for the 'rings.'

Any color you prefer, but a deep indigo would be most lifelike.

Use a Styrofoam ball, and color it with paint, pastels, markers, or whatever else you have on hand.

Cut out construction paper of various colors to represent the different layers.

No, You cannot cut into a balloon without it popping, therefore you cannot describe the layers.

To make a model that can open and close, you need to use hinges, glued opposite to the designated place you want it to open.

Yes, but it will be very brittle, so you need to be careful of it, so it won't break.

You shouldn't write a label on the clay itself. What you can do is label it on a separate piece of paper, or cut out pieces of paper with the labels and stick them on the layer where you want to put it.
