Science Pendulum Art Report

Title: Pendulum Art   By: Bridget, Tara, Mary & Elsie 

Aim/Hypothesis: We thought that it would look like how it looked on the video. We also thought that it would be easy and we would get it first try.

Method: First we got 2 chairs and then we put a 1 meter ruler and tied it  to the 2 chairs after that we got some string and a paper cup and tied that to the 1 meter ruler. We put a hole in the bottom of the cup so the paint would come out then we mixed pink and blue in the cup with someone holding a piece of paper at the bottom of the cup so the paint wouldn't come out. We had some newspaper at the bottom of the the good paper that we were going to use. After that then we swung the cup on to the paper and it turned out like this.  

Results:  On our first attempt the cup was a foot away from the ground.  It was quite messy and unorganized, the string was every and didn’t end up like the ones in the videos.  Once we let go of the string to let it swing and do it’s thing, it just ended up doing blotches of polka dots.  It wasn’t flowing properly and it ended up looking like a mess.  

Our second attempt was a little bit better, but wasn’t what we wanted.  It had the same problem as our last attempt, polka dot blotches and no improvement.  

For our third attempt we decided to change the pendulum by sticking a pencil through the cup and adding a bigger hole.  We secured the string to the ruler and it seemed to work wonders. We aced it at the third attempt. 

Our original idea was to keep it lower to the ground, but one of our team mates told me to put it up higher,  couldn’t do anything else but agree because that’s what makes a team. At least we tried different approaches.   

Conclusion: Overall in the end it turned looking pretty cool. It took a couple of tries to get it right but we got it in the end and it worked.  Next time to make it successful we should do the same process as third attempt, but make the hole slightly smaller.
