We made icebergs or Igloos in our sensory table!
I filled water balloons with water. My freezer takes 48 hours to completely freeze a water balloon. So I only froze these for 24hours. That way I knew there would be a week point and hollow center. I filled the bottom of the bin with some gravel and tore the balloons open. Which also filled the sensory bin with very cold water. Added our little cold weather friends and the kids explored!
We buried dinosaur bones in the sand box. They are actually cow femur bones. To clean them you can boil and then simmer them for around 24 hours on each side in apple cider vinegar. Just to warn you the smell is AWFUL! and it seeps into everything my house will never be the same. Some butchers have a machine that will completely clean it for you ask around.
While studying bugs we were talking about ants and their tunneling systems they create.
To give the kids a better understanding of what we were talking about I added PVC pipes to the sensory table with different connectors. I had meant to buy black beans to represent the ants. But used what I had on hand which were black eyed peas.
The kids had a blast building and creating more “tunnels”
