Marine Biologist Starter Kit


Create a color-changing reef and build ocean animals that move! Learn how scientists explore the ocean, build moving whale and shark automatons, and use color-changing clay to sculpt your own coral reef and play with temperature changes. Later, discover what it takes to become a marine biologist and meet deep-sea creatures.

Why it’s awesome

  1. Colorful coral

    Color-changing clay shows the impact of ocean temperature on coral.

  2. Swimming science

    Automaton tails move in different directions like real fish and whales!

Behind the design

I modeled the marine machines off of real whales and sharks. Except for the wheels, of course. I based those off of train wheels!

    I purchased this for my grandson and I cannot think of a craft that he has enjoyed more. He's anxiously awaiting what I chose for his next box.



    A lid to store the coral ? in the container.



    My 7 year old son is obsessed with this crate!! He loves showing us how the clay coral changes color depending on the water temperature. He was thrilled to be able to complete this mostly by himself, too - so proud!



    The whale and shark kits were so easy and well put together! The clay was dried out in the coral kit, though, so we couldn't do that one. :(

    My kid loved this kit. They were able to do lots of it on their own, learned a ton and have been playing with the projects for days.
