Structure of the Sun
perfect for the toddler stage, by late primary school you should be ready for:
We did a simple papercraft pinwheel yesterday. I never knew a pinwheel was just a square sheet, with a slit to the center in the middle of each side, then folded over four times.
Trying to attach it in the middle was a little tricky. The instructions said to use a push pin and a straw but that wasn’t strong enough to hold it together. We also used a cork but that kept catching on the back. Better get to the bottom of this before starting in on the structure of the sun…
Card modeling is a terrific hobby that has really taken off since it went digital, with the advent of internet PCs + cheap home inkjet printers. One of the many appeals is the number and variety of models that are free for the downloading. At Canon’s site you can find a wide range of model subjects, many of them are quite nice.
If you want to check out some eye-popping examples of card modeling, or want to learn more about the hobby, the best English-language forum is:
Um, this is really cute but unfortunately it has some sort of Engrish problem. “Radiate” layer should be *Radiative* layer, more commonly called the radiative zone. And “Macula” is a part of your eye that can be burned by staring at the Sun but is, alas, not a feature on the Sun. I think they perhaps meant *facula*, but what they actually have labeled is a sunspot, not faculae (which are bright). Sorry to be such an anal retentive nerd about it, but as an astronomer I don’t want to have to teach the next generation of Astro 101 kids that their parents gave them scientifically incorrect papercraft.
We printed our Sun onto card stock (highly recommended) and assembled it with glue stick. We didn’t do the booklet.
Cutting out took about 2 hours and assembly took about 3 hours. Glue stick allows for even application and faster drying times.
Fine pointed scissors are a must for getting the various glue tabs correct.
It turned out pretty good, but a sphere is a very challenging shape to make from paper. You MUST pay very close attention to the guide-lines if you expect the various pieces to fit together.
Overall it was quite fun!
