2019 - Term Two - Week Five - Metalwork!




This is Ben here doing Blog for my second time!

So today we made a shelf out of a book (which Nigel calls the Book bookshelf), but before I can tell you that story, I have to tell you this story. The question of the week was how long would your DNA be if you took it out of your body and placed it end to end?

Answer: If you stretched the DNA in one cell all the way out, it would be about 2m long and all the DNA in all your cells put together would be about twice the diameter of the Solar System. OR Your DNA could stretch from the earth to the sun and back ~600 times.

WOW! That’s long!

The Book Bookshelf:

Nigel told us today that we would be using a new tool: a hacksaw! We used a ruler to measure how long our aluminium rods had to be.


Next, we cut it with our hacksaw.


Once we had done that, we drilled holes on the aluminium with drills so that we could put screws in them.


Next we went into the classroom to watch a video about the history of aluminium. It turns out that aluminium used to be more valuable than GOLD! But now it has some serious competitors now, like titanium and carbon. And at the end, Nigel showed us what it looks like to drill-press metal, and for one I can tell you it looked GOOD.
