In 1967, I was in third grade and got a book by Beverly Cleary titled “Henry Huggins.” In the book, Henry goes to a pet store and buys a pair of guppies. The two guppies had babies. Soon Henry’s room and life are over-run with jars of fish. This story disaster inspired me to ask my parents to let me have an aquarium. My parents agreed, and soon there were three aquariums in our new house.
Recently, I looked back on those experiences with tropical fish and realized just how much science I learned from them. Making the water safe for the fish taught me a lot of chemistry. Learning about the fish, keeping a balanced tank the fish could live in, and breeding them introduced me to topics in biology long before I had them in my classes. Even mathematics, physics and a touch of engineering came into play.
Today, scientists and educators are making a deliberate attempt to interest children in science, technology, engineering and mathematics—it’s abreviated STEM. In the past, such activities tended to be aimed mostly at boys. Now, the goal is to interest everyone, no matter their gender.
I learned through books. My first book on aquariums taught me how to set up a small 5 gallon tank. As I got bigger books, I got bigger tanks. My Dad was an engineer, but for the most part, he stuck to lifting heavy objects, curbing some of my excesses, and suggesting how to look up an answer. It worked for me.
Part of me would love to write a book for third through fifth graders explaining the science as they set up a modern aquarium. Unfortunately, my wife and I weren’t blessed with children. I’m not sure if I’d know how to write for third to fifth graders.
As I thought about it, I realized I don’t want to write for those third to fifth graders. I want to write for their parents. The parents can guide their children, pick and choose the topics that are appropriate, and interpret the lessons for their children’s level of understanding. With any luck, the parents and children have fun together with the tank.
And who knows? Maybe the parents will gain a little more understanding and appreciation for science.
As I see it now, I’ll write a lesson about once a week, focusing on the particular topic involved with that stage of the aquarium setup. That might seem slow, and, as I get a feel for it, perhaps the frequency of the posts will increase. But one of the tricks to setting up an aquarium is to take it slowly. If, in a single day, you purchase an aquarium, set it up, and put the fish in, there’s a high probability that you’ll waste a lot of money and kill the fish.
If anyone is going to follow along, I would appreciate getting feedback. What was clear? What wasn’t clear? What was too difficult for your child to understand? What was too simple? What was too expensive? What better ways are there to do this? A comment section is available at the end of each article. I’ll make every effort to answer questions and learn from any suggestions.
Right now, I'm at Pittsburgh Podcamp 8. This is a social media get-together where we can learn about various aspects...
