This could be use to as an extension of the Old Macdonald had a Farm activity. Create a farm small world scene using sensory materials to encourage sensory exploration, imaginative play, language development, and more!
Arctic play, sorry not sure who to thank for this idea. Fill the big tray with blue tinted water, sit a bowl or tub in the middle, weighted down if need be. Place outside or in freezer (whichever is colder). Add your animals and water in the middle, add some ice cubes to float about in the middle.
