buat fosil dinosaurus

You will need:

• Cardboard box card
• Pen
• Sticky tape
• PVA glue
• Kitchen roll, loo roll or tissue paper
• Sand

Find a huge piece of cardboard box card, and cut it into a wobbly shape, like this. This will form the base for the skeleton.

The idea is to form a dinosaur skeleton from bits of card. You can make whatever kind you like. Draw a skull on some card, and cut it out.

To make ribs, draw lines in pen down a rectangular piece of card. The lines should be a few centimetres apart from each other, but don't go all the way to the top of the card.

Cut up the lines to make strips. If your cardboard is too stiff to move the strips around, put a bit of water on it to loosen it up.

Separate the strips alternately, bending every other section backwards and forwards.

Do the same on some triangular card for the creature's tailbone section.

You could also cut some other random bone shapes out of smaller peieces of card. Try creating legs, arms, claws or feet.

Once you've made all the parts you think you'll need, bend and crush them a bit to make them look old. Remember they're supposed to have been lying around for a few million years!

Scrunch up your backbone and tailbone a bit too - no need to be neat!

Arrange the skeleton bits around the body, and secure with sticky tape once you're happy with the shape.

Take your PVA mixture and cover the whole creature, sticking on the strips of kitchen roll. Lay it on loosely - you don't want to flatten the skeleton too much.

Cover the whole thing in a couple of layers of kitchen roll and glue. At the end it should look like a gluey, soggy fossil!

Now for the fun bit - turning the fossil to stone! While the glue mixture is still wet, just pour sand all over it. It needs to be completely covered.

Don't leave the sand too long before carefully tipping off the excess. You'll be left with a pile of sand to clear away at the bottom!

If the fossil doesn't look completely covered at first, you can always add a bit more glue and sand later! Leave it to dry - and you're left with your own fossilised attack o saurus!

If you haven't got much card you could make a smaller creature like this one. Try it yourself!
