5 Red-Perfect Pulleys…
5 Red were superb this afternoon and I am still smiling as I add this blog. The children were given a tray of items and asked to create some pulley systems. A pulley is a wheel on an axle or shaft that is designed to support movement and a change of direction of a taught cable or belt, or transfer of power between the shaft and cable or belt. It can also guide the cable or exert a force!
Please look below at some of the SOLE work that took place today.
Please write a short paragraph explaining if your pulley worked and how it could be improved even further.
Our group used:
1x wheel
1x stick
1x string.
We put the stick through the wheel then we put the string around the wheel.Then put it around the stick and pull it and your done.
Our pulley worked. We could improve it by somehow attaching the string to the wheel instead of holding it, behind the scenes it kept falling.
Our group pulle worked .
Our could be improved by our voice being louder.
My groups pulleys had worked because we did it carefully and could improved by challenging ourselves by using more weight.
We need those stuff to make a working pulley;
– a yellow stick with holes in it
– string
– wheel
– straw
– bowl / bucket
– heavy object
So what you need to do is to get a straw yellow stick with holes and a wheel
In the middle of the yellow stick with holes put the wheel and put the straw through it with the wheel in the middle.
Put the sting on the wheel so attach the bucket with the object in it from the edge
of the string and from the other end pull it
My groups pulley worked the things we used were
-a yellow stick with holes in.
-a wheel
-some string
-and a heavy object.
-straw
How you make it is you get the yellow stick and straw and put the straw in the middle hole of the stick.Then you put the wheel on the straw.Next you get the string and you tie it on the yellow stick .After that you tie it around your heavy object and you turn the straw around and it should pick your heavy object.
Pulleys:
Our group created a pulley we used…
*string
*1 wheel
*1 weight
We experimented different experiments and we worked hard to create lots of experiments to get it right and lift the weight.
Finally we found out a way to lift up the weight but it could be improved by adding more materials to lift more than 1 weight, that is how it could be imoroved.
Thank you Mrs Raja Khan for staying with us for science
Our pulley worked because it on the wheel the string was running on the wheel so the tester was holding the wheel on top in place.It could be improved by using something else for the wheel because it was keep on sliding of.
Ours worked but I want to improve something our group could be more specific but all the others was good and tried well but if yours didn’t work then try again 😀👏
Pulleys:
My group made a pulley out of…
– String
– 1 Wheel
– 1 Weight
We conducted this experiment by attaching the wheel to a piece of string and then fastening a weight so that a bit of pressure builds on the wheel.
As we did the experiment we found out that the more heavier the weight, the more time to reach the top.
Our pulley had worked but I think that it still could be improved. I think that we could’ve made a strong base ( the place where we put the wheel ) and we could’ve added a few more weights. If we would’ve added a few more weights,it would take a longer time to come up. Other than this I think our pulley was good
Our pulley worked but we could improve by using something else for the thing that make the pulley go up
our pulley had worked it would be able to carry heavy weight , this is how I think it could be improved to hold extremely heavy weight
Maybe it could be improved by tieing the rope more firmly around the stick with holes
If that doesn’t work maybe it will work with a stronger rope here are some of the stuff we used
Straw
Rope
Stick with holes
Water bottle
Wheel

My pulley worked because first we worked together. Are pulley had a thin string so it can fit in the pulley.
Are pulley work it could be improved by trying to not put tape.
I had so much fun it was great
My pulley did great it worked even with a big weight.I think it would improve by better and more stronger equipment too.We used a tall thing that would hold the string up to lift the weight up. It was really fun when we were children listening how to make a pulley like what equipment. A big wheel to use a small wheel to hold it up.
Wow I really did have a lot of fun and the other children did a really good job to.👍😊
My pulley didn’t work because are rope wasn’t stable and we didn’t make it probably,it could be improved if we planned it and we could have a stronger rope…
We used a big wheel
One string of rope
A stick with holes
We made it again and planned it well and we tested it and it
Was a success.
My pulley worked and it could be improved by adding more weight so we could see if it works with that much weight and if it would we could add some more.we could improve it by putting it a bit higher as well.
Group 4
I think we could of improved our pulley by using better equipment. It worked well even though we didn’t understand at first. But we worked well in the end.
Our pulley worked and it could be improved even further if you use heavier weights to test the pulleys.
My pulley worked and it could be improved by lifting more weight
I enjoyed it a lot. My favourite part was when I had to climb up and put the rope over the bars because I could also play and learn.😄
My pulley did work we could improve by using a stronger ropes do bigger wheel to put the rope on
My pulley worked amazingly. Even though the teacher gave us the light weight, it was pretty good. Mine would be better if it could lift more weight.
Well done everyone
👍🏻It was fun to take part in this activity. I enjoyed making pulleys with my group👍🏻
Our pulley thankfully,worked as we followed step-by-step instructions.It could be improved even further if we made it more secure using tape more string etc…🙃🙃🙂🙂
