Life Cycle of a Frog Sensory Bin – with blue oobleck!

Looking for a fun sensory bin idea for your kids? Here’s how to make a simple life cycle of a frog sensory bin – with blue oobleck!

I am pretty new to creating sensory bins. But, my 2 year old is starting to get more inquisitive and more into small world and imaginative play.

Every time I think about setting up a sensory bin, I feel like it’s a lot of work and so I don’t do it.

But, this one was super simple! And I involved Luke in the set up process (IE making the oobleck) which he loved.

Another great super simple sensory activity is this DIY sensory bottle.

I was inspired to do a frog life cycle sensory bin when I saw these frog life cycle figurines on Amazon. Don’t ask w what weird rabbit hole I went down to land there – but somehow, I did.

I actually ordered the set that included life cycle of frogs, butterflies, chickens, and sea turtles, so watch out for more sensory activities coming soon!

Anyways, I had a lot of fun setting this up. Oobleck is always fun for sensory play because you can talk about it feeling firm or wet or slimy.

This really occupied Luke for over 30 minutes. He did NOT want to stop. Warning: the oobleck is messy but cleans up easily with water!

Want more life cycle fun? Here’s a fabulous edible butterfly life cycle activity for kids!

How to make blue oobleck

This makes enough oobleck to fill a 9″x9″ brownie pan about 2″ deep!


  • 1.5 cups corn starch
  • 1 cup water
  • 2-4 drops blue food coloring

Add cornstarch to a bowl and slowly add water. Mix with your hands (kids love this!) Add dye as you mix. Warning: it will dye your hands, but only temporarily.

It should feel like the consistency of honey if you dribble it through your fingers. If it’s too runny, add cornstarch. If it’s too thick, add water.

Have fun turning it from a liquid to a solid in between your fingers!

Simply fill your container with the oobleck and set the frogs and tadpoles inside.

This was my first time introducing Luke to the frog life cycle and honestly I was impressed at how interested he was.

He loved digging for all the parts and especially loved counting the legs on the frogs and tadpoles.

The plastic figures were really easy to wash clean when we were done and all of the oobleck wiped up with a damp paper towel.

Plus, when you are done, you can store the oobleck in a tupperware for up to two weeks and re-do the fun multiple times!
