DIY Dyed Seashells

Summer Sensory Bin Ideas for Preschoolers Using Dyed Seashells is a craft project that transforms into sensory learning when placed into a bin with sand and other “beachy” items. If you’ve never dyed seashells before, think Easter eggs minus the eggs! All you need is some food coloring and vinegar to create a rainbow of appealing seashells.

Benefits of Sensory Bins

Sensory bin activities for preschoolers are a must-have component in every preschool lesson plan. It is a natural way to allow young kids to explore and learn about the world around them by manipulating objects.

Summer sensory bin activities are especially exciting because you can even take the learning outside!

Here are some other benefits of fall, winter, spring and summer sensory play:

  • Fine motor skills develop and improve as kids grasp, pinch, grab, slide, push, hide, and MORE with their little hands and fingers.
  • Language skills develop and improve as they are introduced to new theme-related vocabulary.
  • Sensory experiences allow kids to explore cause and effect.
  • Problem solving and scientific thinking skills improve.
  • Children learn to work together, share, and cooperate.

Other great sensory bin fillers include rice, rocks, cotton balls, pasta (cooked and uncooked), water, bubbles, snow, ice, sticks, grass, leaves, or shredded paper. There really is no limit to what materials kids can explore.

Adult supervision required, of course, especially for toddlers who primarily explore with their mouths!
