Making Model Fossils


Fossils are dead precious and they go back a long way. Everybody loves fossils so in Room 5 we made some. I will show you how.
You need:
Clay,
A small plastic container,
Shells,
Plaster of Paris,
Gold spray paint,
Thin metal wire,
Some black paint,
An old cloth.
How to make one.
First you press the clay into the small container. Flatten it in the container until it’s about 1½ cm thick. You need to make the surface flat.
Next you press your shells into the clay to make a pattern. Pull the shell out when you have finished.
After that you have to make a loop. It should
Look like this. The loop will hang your fossil.
Then ask an adult to mix the plaster of Paris.
Now you can wait for it to dry and paint it gold.
Then lightly paint it black and wipe it with an old cloth.
There you go – a fossil.
