This week we are heading to an imaginary Quarry where you are going to be making some fossils!

You might already know that a fossil is the remains or impression of a prehistoric plant or animal, that has been naturally preserved.

Perhaps you have some fossils at home that you have collected on a trip to Ketton Quarry with school, or on a walk with your family.

I thought that you might like to have a go at making your own fossils at home.

What would you like to preserve? You could make an impression of a shell, a leaf, a lego brick or your favourite toy's footprints (check that the item is washable first).

You will need

• 200g salt
• 150g flour
• 150g coffee grounds
• 100-120ml cold coffee or water
