Work to be completed during the week commencing 20th April 2020.

All work is available via remote access for the school. It can be found in samples\science\working from home.


Describe the structure of the gas exchange system relating to the heart. Start with this video then look at the worksheets in the school samples area.


To start with, you need to recap the electron structure of the first 20 elements (Hydrogen to Calcium). Now research how atoms are different from ions, what an ion is and why are they stable. You need to remember what ions (if any) the first 20 elements form as well as nitrate ions, sulfate ions and phosphate ions. See the work in the school samples area.


This week’s work continues with electricity. Work is available on Seneca Learning, however, before starting that, watch the videos that have been prepared for you here.
