# [S3] Lesson 42 : Static Electricity L1 + Techniques of Differentiation Part 1 +Speed of Reaction I Updates/Debrief

[S3 Physics PMCians]

What we did in 2 hours:

Good to see all of you back after the 2 weeks break!

In the last lesson, we finished our 1st part of Static Electricity where we learnt how to charge an object. Remember we charge by Friction if it’s an insulator and by Induction if it’s an electrical conductor

Watch this cool video that shows how a charged object can actually attract a stream of water!

Special Mention:

This coming week, we’ll be moving on to the 2nd part of Static electricity where we’ll learn more about the electric field and its effects. Also, get ready for some quizzes to earn some PMC dollars!

Should you need assistance in your daily practices in Physics, do send your attempted workings and questions to 9100 1235. We will strive to clarify your doubts.

See you in class!  😀

What we did in 2 hours:

During our first headstart lesson, we started on Basic Techniques of Differentiation. We covered on the basic differentiation and the chain rule,

1)      Bring down power

2)      Power minus 1

3)      Differentiate inside the bracket

We also discovered that

We realised that this chapter requires us to apply some S3 topics, such as Law of Indices, Coordinate Geometry and Simultaneous equations.

Slowly and progressively, we will see that there will be more S3 topics being applied in this chapter!

Please try the Grade-A questions (Page 14 and 20) before referring to the solution.

Special Mention:

In the next lesson, we will continue to learn two more techniques of differentiation: Product Rule and Quotient Rule.

Please be reminded that you are to bring ALL booklets (couriered) for the headstart lessons if you are joining us onsite.

See you in class!

What we did in 2 hours:

We have completed our learning of the chapter on Speed of Reaction where we mastered the five factors that affect how fast reactions occur and learnt how limiting reagents can affect the shape of graphs (i.e. initial gradient => speed of reaction, end point => no. of mol of limiting reagent).

What you take home

We will be having a quick fire quiz this coming weekend on speed of reaction! Do a quick revision of the factors as well as our tips to sketch graphs.

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 a quick infographic on some of the content we will cover.

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.
