I did 10 for each space and when ever I found like a multiple of fifty .After I found what 50g was I added it to be like double the weight and then I did it until 250. I then found the average line.     I drew until the line and came down and it was 170 . When we tried it it was wrong

I was supposed to find the mass of an object if the spring extended 12.1 cm but my graph was too small so now I need to find the mass of a object if the spring extends 9.1 cm.  I used my graph and it shows that the mass would be 103 grams. My method was that from the 9.1 cm spring extension mark an follow it to the average line which brought me to the conclusion that the object was 103 grams

# data[].attributes.body
120g

I used the vertical axis to find 12.1 cm first. Each square is 0.2cm on the vertical axis and 5g on the horizontal axis. 12.1cm would be 20 squares if I started on 8g plus 3 squares below 8g. I used those squares on the horizontal axis after that.

If object has an extension of 12.1cm on your graph, what is the mass?

When you check your graph, you look at the extension of the spring and then you look across in a straight line until it touches the line, after that you look at what’s below the line that’s directly below it if it is 136g then it is correct

I tried to find 12.1 cm but my graph was to small so I found what was the mass of an object when extended to 9.1 I found that the mass of the object was 170g.

# data[].attributes.body
If an object has an extension of 12.1cm on my graph, what is the mass?

Ans:270g

Explanation: I used the average extension of the spring relative to the mass of the weights and kept adding till I reached the 12.1cm mark for length then used the corresponding mass.

Question: If an object has a mass of 12.1cm on my graph what is the mass?
Answer: I will first look at the vertical axis to find 12.1cm. Secondly, I will draw a line from the 12.1 mark to the average line. Next, I would draw the line down to the horizontal axis. Then, I would look at the horizontal axis to look at the mass of the object.

# data[].attributes.body
If the object has an extension of 9.1 ,the mass is 44 grams.

We got this by finding the extension which was 9.1 then make the line to see what the mass is.We drew a line to the trend line and connected it. That is how we got 44 grams even though it might me 45.

# data[].attributes.body
If an object has an extension of 9.1cm on my graph the mass would be 44g. The method I used was that I started with the vertical axis and start on 9.1cm. Then we draw a line towards the trend line and brought the line down to the mass.

Q1.1: If an object has an extension of 12.1 cm on your graph, what is the mass?
The mass is roughly 181.2 grams.
Q1.2: Explain your method.
In order to find the mass of the object, I had to find 12.1 cm on the vertical axis (extension) and create a rough approximate line on where the extension and weight would meet. After doing that, I counted the number of graph squares needed to reach the target (the 12.1 cm point). If every four squares was equivalent to 20 grams, then I would need 8 and a half squares (half because the point is in between the space in the ninth square), which was equivalent to 40 grams and roughly another 2 grams. After doing the calculations (on the squares, 140 grams + 40.2), I reached an answer of 181.2 grams.

# data[].attributes.body
(Result):
If the object has an extension of 9.1cm,the mass should be 46g.
(Explanation):
Firstly,I searched for 9.1cm on the vertical axis.Secondly,I followed the printed line to the pre drawn line.Lastly,I followed the line downwards to get 46 grams.

# data[].attributes.body
if the length of the spring is 9.1,the mass of the object will be 44 grams. Explanation below.

I had to find the mass of an object that extends the spring to 9.1 cm. So i searched for 9.1 cm on the vertical axis of the graph and drew a line to the trend line of the graph. After that i drew a line downwards to get 44g as the result.Then after that, i used the table below to see if my answer was reasonable before i confirmed it.

I learnt that I can use a graph to help in my experiment.

My group used the mathematical method. We first found out the extension of the spring every time we added 20 grams to the set-up. After that, we found out how much is the extension between 140 grams and 120 grams and divided that length by 20 (in order to find out 1g). We multiplied that by 4 so that we can subtract that amount from the spring extension at 140 grams in order to find how long the spring extension will be at 136g. After that, we tried our best to make the plasticine weigh down until we got how long the spring extended at 136g. Although we did not manage to get 136g as the mass of the plasticine, I personally think that it was a good attempt. (I would like to thank Elisha and Isaac for helping me to try this experiment)

My name is Andrey and last week we plot a graph of mass against extension in e2k science  this week we used the graph to measure the mass of the plasticine after we got our diamond we checked if it is accurate with a electronic weighing scale we were far off at first but the second try we got really close and after pinching away a little bit of plasticine we manage to get 136g which is what we needed.

For the experiment first we made a graph where the horizontal axis being the mass of plasticine and the vertical axis being the length of the spring. Then we calculated the ideal length of the spring when 136g of plasticine is hung on the spring(10.7cm). After we completed the graph, we hung the plasticine until we got the ideal lenght of 10.7 cm.(spring).But then we got a problem. The 136g that we got included the hook. We need
to find 136g Without the hook.We used the graph to find out the mass of the hook which was 20 grams and then we added that amount of plasticine to the plasticine to get a very close answer of 140 grams

Last week we tried plotting of graph of mass extensions ended up having the same answer as Andrey as it tried the same method of his instead of Ryan’s . This week me and Andrey both got it wrong we were far of but Ryan’s one wasn’t so far we got the plasticine and we made it according to me and Andrey(31) but yeah  we’re wrong. we used Ryan’s one was wrong but not too far off(146)so we took it off just a tiny bit as we needed 136 to complete it and in the end we managed to do

Firstly ,we used the weights to make a graph.Secondly ,we used the graph to get the length of the plasticine on the spring.
We tried to split the whole plasticine in half and weighted it but it was too less so we added more until we thought that it weighs 136g but when Third,we used the electronic balance to check we saw that it weighted 140g but 4g was less so we did not care and counted ourselves as accomplished our mission.
I learnt that a graph is like a electronic balance.

Last week, we plotted the graph to find how to get the mass of the “diamond”. We plotted a graph of Mass against extension.
We found that in order to get the diamond to be 136 grams we must make sure the spring extends far enough. First we tried Andrey’s method was going by 50g to 100 grams to 150 grams to 200 grams to 250 grams. We marked the distance on the graph then we drew the average line. From the 136 grams marking on the horizontal axis we found our spring extension to be 8.9 cm.
We put the plasticine on the stand then we measured the distance until it was 8.9 cm. We then took the plasticine to check the weight. It was 31 grams. It needed to be 136 grams.
So, we tried again using my method. My method was that we marked out the points from 50 to 70 to 90 to 110 to 130 to 150 to 170 to 190. We then marked out the points of how long it would extend before drawing the average line. I measured from instead of 136, 186. I did that because the mass of the stand was 50 grams so 186-50=136. We then put the plasticine and pinched out until the spring extended 11.1 cm. When we got the spring to extend 11.1 cm, we took the plasticine off to weigh it.
It was 146 grams so it was only 10 grams too high.

On the first day, we plotted a graph of mass against extension.
On the second day we used the graph to measure the mass of plasticine. And then we checked the mass using a electronic balance. The weight we were supposed to have was 136g and e got 140g.Mr Singh said it was alright as a 4g difference was not that much. In the process I learnt that springs are a useful object in life as we can use it to measure how heavy things are by Also using a graph. We do not a weighing scale or a electronic balance. Springs are used many things like trampolines, lawnmowers, sprinklers and etc.

During this experiment, first, we measured and plotted out a graph of mass against extension. we used a retort stand and attached a spring to it, then we put a hook with some weights on it then through a graph showing the mass relative to the
extension of the spring. Then use the same graph to estimate the mass of the plasticine are based on our answers. then we touch the fastest into the hook after getting rid of all the weights. When we finally achieved what we assume was the closest we could get to the right amount we informed the teacher that we had finished and used the electronic balance to double check our answers.

5/7/23, first checkpoint: Plot a graph of mass against extension.
Sophia joined our group in exchange of Hao Yang. She was from the Tuesday E2K and understood how to make the experiment work using mathematical calculations. Apparently the Tuesday E2K was stricter than the Wednesday class taught by Mr Sng. The way she explained everything was easy to understand except when she was doing some calculations. The experiment planning went smoothly thanks to everyone’s efforts. We managed to plot a graph of mass against extension. We were ready for the next week’s experiment process.
12/7/23, checkpoints two and three: Using plotted graph to measure the mass of plasticine & checking the plasticine’s mass  using a electronic scale.
We quickly got to work. Sophia measured the extension of the plasticine while me and Issac added and took out some plasticine. We needed nearly the whole chunk of plasticine to reach 136 grams. Turns out you can’t leave any air holes (Sophia likes calling it A-holes), otherwise it would affect the extension of the spring. It was quite tough to adjust the plasticine, we had to compress it to prevent any air holes and continuously pinch it to remove a few grams. In the end, after using the electronic scale, we had nearly hit 136 grams, but not yet. We reached a mass of 156. Although it wasn’t a perfect success, the experience was interesting and fun.

Last week ,we plotted a graph of mass against extension.Basically we plotted a graph using weight.This week, we used the plasticine to try to get 10.7 cm which is 136 grams.We thought we got 10.7 cm but when we checked with Mr Seng it was 140 grams which from our graph was 10.8.So that means we were 0.1 away from the direct answer. We were still happy with how close we got for our answer.I learnt about how by using pens,pencils and science can get us a more accurate than using a weighing machine and how important springs are in a lot of things.Springs and be used in lawnmovers,sprinklers,trampolines and many more.

# data[].attributes.body
I recorded the measurements on a table and then made the mass the horizontal measurement and the extension the vertical measurement before making them turn into points. After that I drew an average line. Since 136g is in the middle of 120g and 140g, I estimated that the extension would be around 11.20cm. We had to painstakingly hook the plasticine onto a spring, make sure that there were no air bubbles and then remove and add plasticine over and over until it reached the measurement that we were looking for. And then, when it was weighed, it was not close to 136g. And then we tried again. After that, the final result was the same thing but dropped by 1g. But it was cool that a pencil and a graph had helped me to do an entire experiment.

During this experiment, we learnt how to find the mass of an object using springs. For the experiment, we will need a spring, retort stand, weights and clay. First we measured and plotted a graph of mass against extension. We did this by attaching a spring to a retort stand, then attach weights to the spring until we finished the graph of mass against extension and made an average line. Secondly, we used the graph to measure the mass of the plasticine. We did this by slowly adding plasticine to the spring until we thought it was correct. Lastly, we checked the mass using an electronic balance to check our answer.

Part 2:
Question: If an object has an extension of 12.1cm on your graph, what is the mass?
Answer:Using the same items used in the previous experiment and the graph we made, we can find out the mass of an object with an extension of 12.1cm. If an object has an extension of 12.1cm, we can first find 12.1 on the vertical line(Y axis) for extension of spring. After that, we can draw a line from 12.1cm to the average line of the graph. Lastly, we can draw a straight line downwards from the end of the previous line to the horizontal line(X axis) for mass to find the mass of the object.

This week, I plotted a graph of mass against extension.

We took the necessary equipment such as a retort stand, a spring and plasticine.

Next, me and my teammates conducted an experiment to find out the mass of a block of plasticine. We set the setup up then conducted the experiment.

First, we drew the line of 136 grams and calculated the extension which is 10.1 centimetres using the graph .Then, we found out the extension of 50 grams which is 8.4 centimetres. We kept trying different amounts until we got one that we thought was correct.

We used an electronic balance to weigh the block of plasticine but it’s mass was too little. We then calculated the accurate length of the extension and got back to work. When we felt we that got a more accurate answer, we weighed the plasticine block again. This time, the difference was smaller.

We then packed up the equipment we used and did this.

The graphs may look like not much but they are useful and amazing because they can do stuff a electric balance can.
In a graph there is always the vertical line and horizontal lines.
The horizon line extensions for two like weighing a plasticine.like seen On top .tomeasure the weight of To measure the weight of the plaster cinderblock you first have to put a Bring on the resort stand and then after that you got the recor the weight of the plasticine and record the extension
After that you have to keep repeating the steps until you get like the closest wait to the weight that you want to measure Then you Then you record the extension of the spring and then after that you can use another block of plasticine I put in the same spot and would and you keep adding more or removing the block of plasticine bit by bit to get the weight but after the extension of the spring is the same for the first block plasticine you may get the same weight of each plasticine bolck
