How to make ocean fossils

To all my Eco Creatives members reading this blog, I hope you were lucky enough to have joined in time and received Septembers ocean themed box. If you didn't, don't worry, there are plenty more amazing monthly Eco Creatives boxes heading your way! Plus, I share below how your little one can make their very own ocean fossils. 

If you have found this page and are not quite sure when Eco Creatives is, well let me explain. Eco Creatives is a monthly subscription box for your little one (aged 5yo+) which includes a unique, eco-conscious and entertaining activity inside. The activity could be a DIY, like this box, or craft, or a hands on educational activity. Using all eco-conscious products. 

Does your little one love creating things? Discovering new things? Learning about new things? Do you want to teach your little one that they can have all this fun without putting plastic and waste into our precious environment? Then you will both LOVE the Eco Creatives Subscription Box.

Now lets talk fossils

Fossils are the remains or traces of plants and animals that lived long ago. Fossils give scientists clues about the past. For this reason, fossils are important to palaeontology, or the study of prehistoric life.

It's important for kids to learn about past animal extinctions so they can help to prevent future extinctions. This is what motivated me to create this activity, to teach little ones about some incredible ocean creatures and share with them how they can help protect our precious oceans.

Fossil Supplies

To my Eco Creatives members, you will not have to run around the shops looking for your goods, all of what you need is in your Eco Creatives Box ready to go. The below recipe and instructions will help you create more fossils.

What you will need:

  • 4 shells
  • 4 paper cups
  • Spoon
  • 8 tablespoons of plaster of Paris
  • 10 tablespoons of child safe sand
  • Wooden brush
  • 1/2 cup water

Our Eco Creatives members received printed information cards matching the 4 shells they received. As well as a conservation card teaching the little ones what they can do to help protect our oceans.

Ocean Fossil Instructions

Safety note: Please complete this activity outside in a well ventilated area due to the use of plaster powder. This activity is not recommended for children under 3 years due to choking hazard.

1. Place 2.5 tablespoons of sand in each paper cup and add 1/2 tablespoon of water to each.

2. Use the thin end of the spoon to mix all the wet sand with any dry sand.

3. Use your finger to push down all the sand.  Make the top as flat and smooth as you can.

4. Place your shell/starfish face down. Use your fingers to push it down firmly into the sand.

5. Push down on any lose sand that is around the shell so it is nice and firm.

6. Use your little fingers to very carefully lift your shell out of the sand.

7. Place 8 tablespoons of plaster of Paris into a bowl you don't mind getting plaster stuck to.

8. Add 1/2 cup of water to the plaster.

9. Using a spoon,  mix the plaster into the water until there are no clumps.

10. Slowly pour the liquid plaster into each of your cups, covering all the sand.

11. Leave your fossils in the sun to dry for 24 hours, or longer if it's a cold day.

12. Tear the side of the paper cup and take your fossil out.

13. Use your brush to brush away the sand and reveal your ocean fossils.
