Y8 Challenges for week 18-25 nov

You'll have a couple of challenges for this week - all of them will award you xp!

1. Memrise - use it to learn the element symbols!
2. You should start working on an element card - this will be your skills assessment (due next Friday - 29th of November) - the Element card should include basic information about an element of your choice - the symbol, where is it located in the Periodic Table, what are its properties, where do we get it from, how is it used and so on - anything you find interesting about that element!
3. Try to make your own sentence/message using only symbols from the periodic table. Here are some examples:

Just look around you and you will see loads of things that would not be there without Chemistry - from the paint on the wall of your room, to the soft drinks and snacks you grab on your evening out; from the fuels our cars use to the medicine that treats diseases; from the LCD to your phone, tablet or computer - all have parts that involve at least one chemical process in their production. The list could go on forever - but instead of compiling a long list, I'll let you watch a short video about it:
