Understanding how science applies to real life helps students build stronger connections with what they learn in school. Here’s a common real life application question on friction that often appears in Primary 6 Science exams under the Forces topic:
“Alan found it difficult to turn the cap of a bottle of milk. After he wound a rubber band around the cap, he could turn the cap more easily.
Why was Alan able to turn the cap more easily when he wound the rubber band around the cap?”
If this question sounds familiar, you are not alone. Many students find application-based questions challenging because they require more than just memorising facts. They call for a deeper understanding. This exact question was submitted by one of the students using Superstar Teacher’s on-demand homework help feature. The mentor provided not just the correct answer but also a clear explanation of the science behind it, helping the student grasp how friction works in everyday situations.

- Hi<div>
</div> - hi
- let me tell you what im not sure with in this question first
- yes sure
- i dont know why they must tie a rubber band there around the cap?
- because it slips
- the hand cannot open the cap because it slips
- what is this '''ít'?
- sometimes it will happen to you
- when you try to open a jar
- or you witness somebody else having trouble opening a bottle
- by wrapping rubber band, it increases the friction between the hand and the cap
- ya but then how does tying a rubber band help reduce friction??
- it increases friction not reduces
- i mean increase friction
- ya....i typed it wrongly
- sry
- for example, if the floor is wet, and you are barefooted
- you would likely slip
- but if you wear a shoe, then chances are you will not slip
- there is not enough grip
- so is this experiment like can be done in real life??
like life sciences or something
because i never knew that when tying a rubber band around a bottle cap cover, it can increase friction
and not let the hand which is openning the cap slip
its kind of interesting, maybe i can go try it out some day - oh ok
- yes it does!
- it works in real life because I have tried it before
- and I have tried it multiple times
- can can
thank you for teaching me teacher for your patience and guidance
i can finally understand now - thank s alot
- bye :)
- because the jar was so tight
- see ya!
- ok
