Beach Cast Outdoor Activity - FamilyEducation

Beach Cast

At the beach, gather sand, seashells, and whatever interesting items you find. Create a plaster of Paris cast or mold with these things, as a memento of a wonderful day.

Activity for an individual child

Age group: 18-40 months

Duration of activity: 15 minutes


  • Pie tin or other small container
  • Small shovel
  • Wet sand
  • Seashells, driftwood, and other medium-sized beach items
  • Plaster of paris
  • Water

This is a wonderful way for your child to preserve memories. Beach casts also make great gifts.

  1. Have your child shovel wet sand into the container to fill it about a third of the way.
  2. Let him select items to add to the cast. Limit the items so that there is some space in between them.
  3. Show your child how to press the items so they are securely stuck into the sand without being buried.
  4. Mix water and plaster of paris according to package directions.
  5. Spoon the mixture over the sand and shells so that it reaches the rim of the container.
  6. Let the cast dry for a few days then gently remove from the container and rinse off.
