Year 10 SRP Help (1 Viewer)

[Study to success]

also last year I did my SRP in the term 1 holidays and it was due first day back of term 2. We didn't get that long to work on it

 

[Tony Stark]

the effect the length of the string of a pendulum has on its period

Independant variable: length of string
dependant variable: mass of weight
Measured varibale: period of motion

For the control variable, maybe just do it with no mass attached?

For your hypothesis, you can say that you are "Quantiitatively analysing the relationship between string length and period of pendelum motion".

dependent variable is the time it takes for one period, the mass is a controlled variable(not a control), and I can only set mass to 0 if it's independent. I will reread my hypothesis and see how I can make use of your hypothesis suggestion, bc I forgot what I initially wrote.
I've kinda referenced the in focus textbooks but thanks for the working scientifically pearson one anyways, I'll see if I've missed anything out.

No problem, trust our judgment more than mine because I only have a shallow understanding of your report. Is it possible for you to get feedback from other science teachers in your school? Or you could cross-reference other students and see what they did, even if their experiment is different you may still get at least some ideas.

We're not allowed to get feedback except for the general feedback sheet (I wouldn't say it's feedback, just advice + hints), I might check w my friend since we're doing the same experiment but different classes (all her teacher said as an example was that the pendulum was never actually gonna reach the drop point again, but I don't have any info on that so I can't include that in my experiment) but aside from that I should have finished the experiment by this week.

For my control I'm js gonna find a way to yap abt the middle value of 40cm (like a positive control cuz that's the only thing scienceready told me) to observe the difference of the values above and below it.

Or would a string length of like 1/5cm be a better control? My string lengths are every 10 cm from 10cm to like 70cm.
