[S4] Term 1 Week 9 (2-8 Mar) Updates/ Debrief

[S4 Physics PMCians] 

What we did in 2 hours:

Last lesson was all about DC circuits! By now, all of you should be familiar on using Ohm’s law in a DC circuit. But more importantly, you will know how to apply the shortcut methods of Potential divider (for components in series) and Current divider (for components in parallel). We also learnt about special resistors (aka transducers) such Thermistor and Light-dependent resistor (LDR), in which their resistance varies with temperature and light intensity respectively.

 

What you take home:

This is the same circuit builder simulator which we sent out a few weeks back, but this time, go to LAB and try constructing a series or parallel circuit, and predict the current or potential difference across the components using the ammeter or voltmeter respectively. Play around with it and try different combinations without having to go into an actual lab. =)

Special Mention:

As you know by now, DC circuits is such an important topic that we can’t wait to test your concepts next week, so you will be more confident and adept in using the correct methods to solve a DC circuit problem efficiently!  So, get ready for more tests and quizzes next lesson. Let’s “complete” more circuits to get smarter and “brighter”!

What we did in 2 hours:

This week, you are bombarded with series of tests and quiz, and all of you have shown that you have acquired the knowledge to solve questions involving differentiation as we have a numbers of you passing with flying colours! Congrats and keep up the good work.

Please download the additional questions for your learning

 Special Mention:

Do you know that we can also find the derivatives of Trigonometry, Exponential and Logarithmic Function? In the next lesson, we’ll kickstart our differentiation of other function. See you in class!

 

 

[S4 Chemistry PMCians]

What we did in 2 hours:

We have completed the chapter on Atmosphere and took the opportunity to master PMC CHEM’s trademark three-step problem analysis which enables us to “get behind” our teacher’s mind to anticipate and answer data-based questions with confidence and accuracy.

 

What you take home:

You are ready to complete the questions in the Take Home package till Pg. 7 as well as Q1 of section B.

 

Special Mention:

We hope that through the chapter on Atmosphere, you are also able to appreciate how pollutants may harm our environment and us whether directly or indirectly. We hope that you, as custodians of the future, are able to apply your scientific knowledge to solve these problems with innovative solutions.

 

Here’s a video on carbon capture, a modern technology of reducing the amount of carbon dioxide in our environment.
