Good day S1 Scientists!

As promised here is the blog that I’ll update as often as I can with links to science that we will cover in the class on Mondays, Tuesdays and Fridays.

Pupils can expect to cover topics in Biology, Chemistry and Physics this coming year. Keep an eye on the blog for course updates, interesting links, photographs of experiments carried out and most importantly homework updates.

Whether you are a parent of a pupil in PL  or a student you will hopefully find this of some interest. First up is the link to the video on Airships.
