Learning to Write a Hypothesis with Color Changing Animals

Learning to write a hypothesis is always a challenge for my students.  I found these amazing color changing animals on Amazon and thought these may provide an engaging and fun way to learn more about writing a hypothesis!

I have created a pack using these color changing animals.  The pack has three posters:

What is a Hypothesis?

A Good Hypothesis...

Things to Think About...

They come in black and white and with a rainbow background color.

The color change animals come in a few different forms.  These include alligators, lizards, dinosaurs, and sea animals.  Our school mascot is an alligator, so that is the one I chose to use!  You can do these labs with just one box of 12 animals, or you can use a couple of boxes!  

Students begin by testing the animal in cold and warm water.

These animals are about 6 inches long and come in multiple colors!  

Heat, or warm water, makes them change color.  Holding them in your hand firmly for a few minutes will also cause them to change color.

The last lab in the pack has students try to figure out another way to change the color, like exposure to sunlight, etc.

They are really fun to play with in the classroom science class!

You can choose a lab for cold water and a lab for warm water OR one lab that let's each student group choose a water temperature (cold or warm).

The materials for these labs are really cheap and easy to find!  The color changing animals can be instantly reset to their original color in cold water and they can be reused!

You can purchase the pack in my tpt store or on my blog if you are interested!  Click here to check it out!
