Last year, we did a flight unit in our homeschool and I always like to add sensory elements to everything we study. It allows the kids to explore and use their imaginations and helps their retention. Recently, we created three sky sensory activities that would have complemented that unit nicely including this sky sensory bin. They would also work well with a weather unit.
For this sky sensory bin, we used a base of dry pasta that we dyed blue. If you’ve never dyed pasta before, you can read about how to do it using either rubbing alcohol or vinegar. (click those words and it will take you to simple tutorials for each method)
For the actual bin for this, I used a clear food storage container that was fairly deep. After filling it with the blue pasta shells, we added some of the items from the In the Sky Toob and used the remaining items from the tube to add to our Sky Sensory Bag and Sky Sensory Bottle.
The kids cut cloud shapes out of white foam and added them into the bin. We also added cotton balls to represent fluffy clouds. I like how colourful the items are. They make this such a cheerful looking sensory bin.
The hot air balloon from the In the Sky Toob was a particularly popular element and there were several imaginative play scenarios that resulted from it.
