I am a mother of three girls. That means we have a lot of glitter, a lot of pink, and they are both obsessed with unicorns and mermaids.
Recently, we completed a series of unicorn STEM activities, but as the weather has gotten warmer, the kids are more interested in mermaids right now.
They also both really like science experiments for kids. So, I’m sure you know where this is going. It’s time for mermaid science experiments!
If you love learning with mermaids, be sure to check out STEM mermaid activities for kids!
We’ve been doing a lot of awesome science experiments with mermaids. It’s so much fun adapting our favorite STEM activities and science experiments into mermaid themes!
Super Fun Mermaid-Themed Science Experiments
I bet you didn’t know you could combine science and mermaids so easily! We’ve found that these science experiments with mermaids are totally awesome, and some of the most awesome science experiments we have ever done!
If you have any mermaid lovers at home or in your classroom, try these super fun mermaid science activities!
Mermaids for Science? They Don’t Exist?!
Mermaids are just about the farthest thing from science, so, you might wonder how we decided to combine the two. I’ve found over the years that when you use subjects that kids care about, they are more likely to pay attention to the less “fun” parts of the lesson.
So, when kids love mermaids, and you use those mermaids to teach scientific concepts, the concepts will stick. You can even take mermaid science a lot further than we have, by exploring the (theoretical) science of mermaids themselves. How would they breathe?
How would they talk under water? How are they able to breathe water and air? Or are they?
Is a mermaid design scientifically plausible?
Add these mermaid experiments to you science fair project ideas.
Mermaid Science Lessons
Kids can learn just about any scientific concept with these cool science experiments.
In our list of mermaid science experiments, kids will learn about states of matter, polymers, chemical reactions, oceans, ocean creatures, currents, how temperature affects movement, how fish rise and sink, how to remove salt from water, and more!
The Scientific Method for Kids
When doing a science experiment, you need to include all elements of the scientific method, which are:
- Ask a question
- Research the question
- Hypothesize an answer
- Test the hypothesis
- Analyze the results
- Change the variables and test again
- Record the data
