Coral Reef Fish Math!

Last time I blogged, I had just published my very first EVER Marine Biology curriculum unit, Marine Fish of the World with Coral Reef Fish. I'm super duper excited about this unit not only because of it's colorlicious photography (thanks to SO many amazing photographers offering their work to Creative Commons so long as we attribute their name to the photos) and cool vintage black and white graphics in the public domain, but, because my research on the colors and patterns of coral reef fish, more specifically triggerfish, was very satisfying. Teachers love learning too. I have so much fun digging deeper into topics that textbooks never have time for. Why wouldn't it be a priority for students to derive mathematical connections from some of the most colorful creatures on the planet, coral reef fish? 

Let's have a look at some of the fun colors and patterns of coral reef fish along with a few snapshots from my marine fish unit.

Hands down, my most favorite coral reef fish, and fish in the world.....and likely unarguably the most colorful fish in the sea........................

Tadaa! The mandarinfish! This week I taught my first Marine Biology summer eWorkshop lesson on JUST the mandarinfish. I'm sorry that the class is not up anymore, but once we CurrClick teachers start a course, the enrollment comes down. BUT, check out my cool mandarinfish resource page here. 

How about that, now! An entire 1-hour eClass JUST on the mandarinfish! The students loved it! Just take a moment to look at and admire all the wonderful colors and patterns you see on this graceful fish. Check out a video of it from the mandarinfish resource page (scroll down to the videos) to see just how graceful and lovely they really are! 

I see a remarkable cobalt blue, which is unique to this fish since it's produced by it's nude skin's cellular pigment. Yes, it's a nude, scale-less fish in the Dragonet family composed of over 180 other species! I CAN'T WAIT to dig deeper and research the other colorful family members. The video from my page entitled, "Mucky Secrets - Part 9 - Mandarinfish & other Dragonets Lembeh Strait" (scroll down to the first video beneath the Informative Videos heading), shows a few of the other Dragonet members including the mandarinfish. Notice the waved lines that look like a child's marker drawing. How about the converging lines on the fins, lovely yellow spots and concentric purple and red rings around its eye! All of these patterns I described, are studied in higher maths. Why not bring more beauty into the mathematics curriculum both for young and old?

And now for our finale........the triggerfish!

It's a vintage image, one of my favorites. The artist really captured the unique ovoid body shapes.

Just look at and admire those outstanding orange stripes! Below you'll see parts of the marine fish unit with the exercises for observing colors, patterns, numbers and shapes in the triggerfish.

Students study the diagram above and use the fish's external anatomy in their mathematical descriptions in the exercises below.

And yes it does have a red tooth!

You can check out the rest of the preview of the Marine Fish of the World and Coral Reef Fish from my Teachers Pay Teachers store! Just click on Preview beneath the unit's cover image.

The Marine Fish of the World with Coral Reef Fish Unit IS FINALLY HERE!

She's finally ready! After hours, days, weeks....no months, of research and writing, the Marine Fish of thee World with Coral Reef Fish unit has arrived! She's composed of three PowerPoint lessons, each with an accompanying activity guide. Here's the cover I designed for it.

You can have a look at the curriculum here on sale at half price from $8 to only $4 at my CurrClick Home page and at my Teachers Pay Teachers store here. Both give a good description of all that's in the unit instead of me re-writing all that here.

So, of all marine biology topics, why fish? What's so special about fish? According to this nifty little pdf poster (also found on my marine fish pinterest board), not only do they supply immense entertainment among aquarists and amateur hobbyists, are beautiful to look at in the wild (if you have the opportunity to snorkel or scuba dive) they provide a whopping $25 billion dollar food industry! How many of us rely on fish as a part of our diet? And $9 BILLION is made in reef ecotourism PER YEAR of folks coming to look at FISH too! Fish are really important to us. Unfortunately, the oceans need a major serious clean up job, of which I'm hoping for deeply to happen in the Ocean Cleanup project for started by young Boyan Slat, a Dutchman. The dear oceanic community is under seige, mostly....by human activities, of which I won't belabor here.

I hope you enjoy all the fun freebie resources I have for this unit. Even though I use the unit for my online middle/high school classes, the unit can be appreciated by students of all ages. Yes, even you adults. I've my marine science pinterest board loaded with 53 (at the time of writing this) UNIQUE, and I do mean, unique, fascinating, interesting art projects, activities, experiments and resources about these rather remarkable creatures that many of us just deem as food. Remember in Finding Nemo, when the sharks had their AA meeting and repeated over and over..."Fish are friends, not food!" Well, this unit doesn't really get into fish cuisine (although I enjoy some good healthy fish choices every so often myself) as much as it does their personal lives. And we do get personal by looking at some of their internal anatomy. Enjoy the unit, if you'd like!
