I currently have a toddler that loves to jump from activity to activity because the world is her oyster!  At least for this age it definitely seems that way!  Her senses are growing and integrating constantly, so exposure to different textures, smells, sounds, etc. are not only fun they are IMPORTANT!  

Not to mention that teaching new vocabulary related to events we experience during seasons can be a great way to generalize new words across all sorts of environments!  With that being said I respect that parents are busier than ever before.  These bins are not only super simple to make, but they can be sealed up and stacked on top of each other almost like puzzles!  Your child can play with them for days or weeks for expanding learning!
