[S3] Term 1 Week 7 (17-23 Feb) Updates/Debrief

[S3 Physics PMCians] 

What we did in 2 hours:

Last lesson was all about Kinematics graphs! By now, all of you should be experts in graph conversion, and have the necessary skills and knowledge to derive an s-t graph or a-t graph from a v-t graph easily! 

We hope you love graphs as much as we do! 

 

What you take home:

Try out the graph simulator below to revisit your concepts again. Adjust the nodes on the v-t graph to see how the s-t and a-t graph changes accordingly. See if you can guess the shape of the graphs?

Special Mention:

Next lesson, we’ll wrap up Kinematics with a few tests and quizzes, and we’ll also show you how to solve Kinematics problems with the 4 ‘powerful’ equations of motion, which many schools do not teach at all. See you then!

What we did in 2 hours:

We continued on Quadratic Inequalities, concepts namely:

  • discriminant of quadratic equations
  • Intersection between line and curve
  • Proving techniques in this chapter

together with understanding various key phrases (Page 85) which helped us determine the nature of roots from the THREE cases (Page 84) without solving the equation!

 

What you take home:

Please do the Take Away Questions (Quadratic inequalities), Page 112 – 114

 Special Mention:

In the next lesson, there will be a Test on Quadratic Inequalities (concepts 1 to 3). After the test, we will then move on to learn about Polynomials, focusing more on functions with x to the power greater than 2.

What we did in 2 hours:

We completed our Topic Mastery Quiz and kickstarted our learning on the Mole concept and Stoichiometry. Through the rigorous questions, we mastered how four different formulas can be applied interchangeably to calculate the number of particles in a given substance.

 

What you take home:

Spend some time to familiarise yourself with the use of the four formulas (especially formula #1, #3 and #4) as they will be frequently used in our lessons over the next few weeks. You can also begin to attempt the questions in the Take Home Package to consolidate your learning.

 

Special Mention:

Congratulations to the top 3 scorers in our Topic Mastery Quiz

1st – Tan Xiao Zhuang, RGS & Cayla Tham Xin Yi, CGS

2nd – Kong Jia En, RGS

3rd – Allison Law Li Xuan, NYGH & Yang Yuan Ming, SJI
