Science Pendulum

Aim/Hypothesis: See how mass really affects the period of the pendulum. We could find
no evidence of this online but it goes against common sense so we decided to test it. Our
hypothesis is that it wouldn’t affect it at all. (Thomas thought that it would)

Method: 

1: String up two containers to a solid bar or similar object (we did it to the monkey bars)
Make sure they are the same length from the bar (you may need to do a control test with
no water to make sure you have got it right.

2: Fill one of them with some water (we put in 200ml). The first container weighed 84g
(without water) and the second weighed 284g

3: draw them both up to the same height and release at the same time.

4: record results.

Results: First of all we did it with two glass beakers on the end of the strings but then the one one with the water in it smashed after the string snapped. So then we got to plastic containers and some stronger strings. When we tested it they didn’t swing backward and forward at the same time like the control test. We thought that the period of the pendulum had changed because they weren't even any more and that google must have been wrong, but we were wrong and after extensive research and small scale testing we found that the period hadn’t changed but the more massive one kept its momentum better due to its mass and therefore swung for longer and faster. But they both crossed the middle at the same time. We were tricked by our eyes.

KKN Is Honesty important? Link for article in comments

1. I think lying is bad because lying makes the situation worse because the person you’re telling may think that the lie is true and they might let you away with something horrible like punching someone or breaking something expensive. I think honesty is important although you may get punished it would be a better punishment than if you lied and the person you’re telling found out that you were lying the punishment would be worse.
2. You may get away with what you did but in many cases you don’t. I would be lying to say I haven’t lied before which is why I won’t say it but many horrible time I have got away with doing something bad. If you didn’t like one of your siblings and you told your parents that they did it they would get in trouble and you might feel good depending on what type of person you are.
3. I think it is human nature because no one wants to get in trouble and we lie to get out of being in trouble and we get to do the normal things we do. Maybe we lie so that our schedule doesn’t change because we have already planned what we are going to do and we want to do what we have planned and if we don't get to do what we planned we will get annoyed.
4. I don’t think lying will ever stop because it is human nature although I think there will be easier ways to tell if someone is lying like lie detector and you put a pair of glasses on and it scan the person you are interrogating and if they are lying the glasses will buzz and they will be caught.
5. Haven’t really lied to kahi before an if I have I cannot remember lying to him. I have lied to people before but I think everyone I lied to has found out I was lying.
6. Breaking News: Prison are overflowing many new prison have to be built to accommodate all the prisoners. “Woah this is too serious” Said the prime minister. As her Two ic I had to comfort her in this situation but I wasn’t sure anything would work. We had to make a plan of action against rising prison population. We decide we would have to double up prison cells and hope that works. 4 MONTHS LATER Breaking news: 128 prisoners killed by roommates in the last 4 months could this be the end of our prime ministers reign at the top seat. Maybe continued…

Refugee Response

This term in class we have been reading the amazing book Refugee. Kahi and I did a response on the book. Hope you enjoy and leave a comment if we did something wrong or could do better.

Bailed up response

This artwork, called Bailed up by Tom Roberts, was made in 1895 using oil paint on a canvas. The artwork is based on a holdup by a gang of bush rangers robbing innocent civilians passing through the Australian outback in the 1860s.

This artwork will make the viewer feel like they’re in the 19th century.

The detail in this artwork really brings out the minor things like all the bushes, broken sticks and fallen down trees. It makes the setting look dehydrated and desolate.

The sandy dirt colours in this artwork really paint a picture of what it would be like in the Australian outback. All these tones make the artwork stand out from others artworks.

In this artwork it looks like Tom Roberts has used one brush stroke. The artwork would look better with more brush strokes and different size brushes.

Overall I think this is a very good painting and I recommend going to this website to see more of his artworks.
