[S2] Term 1 Week 10 (9-15 Mar) Updates/Debrief

[S2 Maths + Science PMCians]

What we did in 2 hours:

This week, we started our first Science lesson on Chemical Changes.


After a quick recap on what you should have already known about ionic and covalent compounds, we move one to something where Maths & Science meet — balancing chemical equations!


Then we had a good introduction on Chemical Changes and learnt some reactions using heat and light.

What you take home:

It’s March Holidays! So sit back and enjoy two videos related to what we have learnt in this week’s lesson.


Thermal Decomposition of Limestone (calcium carbonate)



Photochemical Decomposition of Silver Chloride


Special Mention:

We will continue and complete our Science lessons on Chemical Changes in the following two weeks.

Till then, enjoy your March holidays and see you again soon. 🙂
