This week’s theme is sink or float. Peanut (34 months) and I have been playing with objects from nature recently and so I decided to use natural and/or found items for our sensory sink.

What We Used:

  • pinecones (2 types)
  • pine needles
  • rocks (different sizes)
  • a small piece of wood
  • acorns
  • a shell
  • a periwinkle
  • sea glass
  • a piece of pottery found on the beach
  • a walnut in its shell
  • dry lentils
  • a raisin
  • a cashew
  • a wooden bead

Peanut watched me collect these items from around the house and excitedly said, “I’m ready to do the sensory bin!”. Never mind that it was a sink rather than bin based activity; I was just pleased to have such an enthusiastic boy!

We began by putting a piece of felt on the bottom of the sink since we’d be dropping heavy objects into it.

I put a washcloth on each side of the sink. I put a card with the word “sink” on one and a card with the word “float” on the other. Peanut is obviously too young to read however he does understand that words in our environment give us information. I chose different colored cloths to help him remember which one was for the items that sunk and which was for the items that floated.

I then gave him the container with all the objects I’d collected and he began dropping them one-by-one into the sink.

For the most part Peanut did very well assigning each item to the correct washcloth. I believe in the philosophy of learning through play however, so when he grew tired of classifying each object I simply let him enjoy playing at the sink.
