How to Make a Fossil



In Room 5 we made fossils because they are so rare. If you want to make one, this is what you need.
Clay,
Plaster of Paris,
Black paint,
An old cloth,
Shells,
Some wire,
And a little plastic container.
This is what you do.
First you press the clay into the plastic container with your thumb. Keep pressing until it is 1½ cm deep.
Next you push the shell in the clay and then take it out again. Does it make a pattern? If it does not make a pattern, press down harder.
Later get an adult to mix and pour Plaster of Paris into the container. Pour it until it is 1½ - 2 cm deep.
Then get the piece of wire and twist it into a loop. Put
the loop into the plaster of Paris. Just make sure that
the circle is sticking out.
Leave for at least two days then take the Plaster of
Paris out of the container and let it dry for another couple of days.
After you dry it you need to spray paint it with your gold paint. Let it dry and after it dries you paint it with your black paint. Before it has a chance to dry, wipe it with an old cloth. Then if you want to you can varnish but we didn’t because it looks fine without.
Now it’s time to hang it on the wall.
