Whats Going on in the Lab? Geodesics!

Welcome back STEM Friends!
It's Wednesday and time for another edition of
What is Going on in the Lab!

STEM Challenge: Building domes in the STEM Lab! A very mathematical challenge with a lot of trial and error! Includes measuring, geometry, and more! Check the blog post for more photos!

It's all about these Geodesic Domes!
Okay, let's start with some background.
I was scrolling through a photo service that I subscribe to trying to find a photo for something I was creating. (Just in case you did not know this: It is not okay to just search Google images and copy and use photos you see. This can cause you BIG trouble, so check into some photo businesses like Dollar Photo Club, and use those!)

Anyway, I saw this photo!
Pretty cool, right? So I started thinking of how we could build something like this and then I found this photo:
This one seemed a lot more doable for fifth graders.
I mean, after all, it's a just a bunch of connected triangles, right?
With just the tiniest bit of researching I found out this is a Geodesic Dome!
BAM! We could build this and I had thousands, yes thousands, of the perfect supply:
STRAWS
(Have you read my blog post about Straws, yet?)

So, I had my fifth graders bring their personal devices to class one day and they spent some time reading about geodesic domes and sketching ideas.

Y'all, look at that last drawing.
Really.
The sweet young man labeled his drawing with a Key. The dots are pipe cleaners and the lines are straws..... If I were writing this on my phone I would insert one of those emojis of a person laughing with tears coming out of their eyeballs.....

Okay, now the teams talked and had to make a monumental decision about the geodesic structure.
Would it be a dome or a sphere?
I am not going to lie to you about this.
This was a major decision.
We wanted spheres because they were really the coolest things ever.
Here is what we got instead:

It is hard to make a sphere.
So, some of us changed our plans and made fabulous dome shapes.
It was purely fun and so mathematical, dare I say!

Connecting triangles made little hexagons. Then a bunch of hexagons made a really large hexagon.
I had a fifth grader say this, "We should have already known this stuff about the triangles and hexagons cause of pattern blocks!"

Anyway, we ended up with some dome shapes and a few almost spherical shapes and it was EASY-PEASY. The best kind of STEM Challenge!
