After several months of not-much-chemistry I'm picking up where I left off doing Ellen McHenry's 'The Elements" with dd. If you haven't checked out Ellen McHenry's website, please do. There are lots of fab freebie printables to download, as well as various downloadable curricula to purchase. We've used both The Elements and Carbon Chemistry (a follow-on programme) with my boys and I can highly recommend them. They are particularly ideal for that tricky pre-teen age, when children often seem to want a bit more of a challenge, but still want to do lots of hands-on learning.
So, today we were back to the periodic table and learning about atoms by using Skittles sweets to show electrons in their orbits. Of course we use sweets for our demonstrations as much as possible. It gives me an excuse to go to the shop and buy chocolate for myself. Not that I need excuses ;)
Inspired by what we've learned today dd and I are now in the process of making a giant periodic table. The hope is to make one large enough that we can actually stick little bags of examples of the elements (the non-radioactive ones) onto the table. Or at least stick photos on. Well, that's the idea.

You can find various printable versions of the periodic table here.
http://sciencenotes.org/printable-periodic-table/
(We have decided to use this totally blank periodic table so we can add our own pictures/samples and titles
http://sciencenotes.org/blank-periodic-table/ )
The files will print out to standard A4 size.
To print out a really massive version, on more than one A4 sheet:
1) Download the PDF of the table you prefer.
2) Open up the PDF
3) Click on print. This will open up the various print options.
4) Select 'poster' (on my screen this is to the left of the print options, about half way down, and has a little picture of 4 sheets of paper)
5) Increase the size of the tile scale (I've just printed mine out at 500%). You might need to click in another box to refresh, but you should find a small image displayed showing how the pages will be arranged.
6) When you're happy with the size, confirm that you want to print.
7) Stick the pages together. You might find it helpful to click print again, put in the same tile scale and refer to the little preview to help you piece together the jigsaw of pages.
