[S3] Lesson 43 : Static Electricity Part 2 + Techniques of Differentiation Part 2 + Speed of Reaction II Updates/Debrief

[S3 Physics PMCians] 

What we did in 2 hours:

We have finished our head-start lessons on Static Electricity, where we learnt how to draw the electric field of charges last week. 

Congrats to those who won some PMC dollars for our 4Q quizzes! Good job and keep it up!

 

What you received:

Do play around with this electric field simulator to see how the electric field changes as you move around the charges.

Special Mention:

Next week, we’ll be moving on to Current of Electricity + DC circuits. Get ready for an electrifying lesson! 

See you in class!  😀

What we did in 2 hours:

During our second headstart lesson, we continued to learn more Techniques of Differentiation. We learnt how to apply Product Rule and Quotient Rule.

After applying the techniques, we should always simplify fully by factorising the common factor and using the law of indices.

We also see that we can deduce the range of x such that the function is increasing/decreasing. This brings us back to our Quadratic Inequalities.

Please try the Grade-A questions before referring to the solution.

Special Mention:

In the next lesson, we will continue on Nature of Functions. We will look at the stationary points of the curve.

 

See you in class!

What we did in 2 hours:

We have completed our learning of the chapter on Speed of Reaction and applied our knowledge on top school questions with a quick-fire round and take home questions. You are now well equipped and confident to tackle any speed of reaction graphs handed to you in your quizzes.

 

What you take home

Do take a look at the Take Home Questions and notes again before the start of the school year so that you are ready to hit the year running for Chemistry!

 

Special Mention:

We will be continuing our learning into the chapter of atmosphere in the upcoming lessons where you will need to tap on your knowledge on acids & bases to propose solutions to atmospheric pollutants.

 

Here’s an infographic to summarise all our learning in Speed of Reaction!

Students can choose to attend any of the timeslots onsite in the respective outlets or live from home at the same timing. There will be both ONSITE and ONLINE audience for all classes. ONSITE and ONLINE students will be able to interact with one another and the tutor will be able to engage both audiences. Both platforms (onsite and online) will be carried out concurrently, ensuring that students in the physical classroom and those attending lessons via Zoom are taught exactly the same content, at the same time, by the same tutor.
