We have been learning about water resistance and what shapes float on water and how many marbles they hold if they floated.Water resistance pushes against gravity, similar to air resistance,but takes place in water. This is part of what helps boats to float. Part of the experiment was shaping plasticine into different shapes to see if they floated. We had a range of shapes, including flat discs and boat shapes. If they floated we then added marbles to test the weight they could hold.
This week within 5J we have further developed our understanding of rivers and how they work. We have discovered that rivers are split into three main parts. These are the upper, middle and lower course. These three areas of the river have specific features that are mainly found within them.
I’ll let Emily explain.
The upper course of the river is the first part of the river and were it starts. The course starts at the source, this leads to ground water then to springs and then the springs go on to form streams.
On either side of the middle course there are floodplains that flood due to heavy rain quite often. Sometimes a river (a tributary) can join another river. Sometimes there are meanders in the river, which are bends. If a river floods the neck of a meander will become flooded as well.
The lower course of the river leads to the mouth which leads off into the sea, estuary or channel. The lower course has bigger meanders. It also has lower energy which means it carries less materials, it deposits some of its soil which forms small islands or deltas.
Last Monday, 5J went to the Star Center in Keighly. The children written recounts of their trip and we have picked one to share with you on our blog. Here is Poppy’s recount.
Yesterday, we had to get up really early to catch the coach to the Star Center
At 7:30am we were all here. After we waited for everybody we got on to the coach, with cup holders and foot rests, then fastened our seat belts. After a while, we reached our destination, Keighly College. We went into the college and was introduced to two people, Becky and Bernard. Then we went to the toilet after the long trip.
Then we hung our packet lunches up up on the pegs or in the cupboards. We went into the briefing room to have an interesting introduction to space. They told us how many kilometers are in a light year and how far the nearest galaxy is to us. They then split us up into 2 groups. Groups Mars and Jupiter, were the names we chose for our groups. I was in group Mars. First group Jupiter went in the cosmodome and Mars went in mission control. Then we swapped over after half an hour but team Mars got more time in the cosmodome because the projector broke.
Then we went back to the briefing room to have our dinner. I was next to Lacey and Kieran. We then went into a space pot and we were in our two groups again. We went into 3 labs, science, robtics and hunting aliens. Then we went back into the cosmodome and looked at the stars on the northern hemisphere and the Milky way line. Then it was time to go home. When we got off the bus it felt funny because it was warm on the bus and cold outside.
This week we have also had a follow up visit in which the children spoke about all the things they had learnt on the day and received a book about Space.
This week across the school it has been Safer Internet week. We have been looking at how we can keep safe on the internet and what we can do if we see or hear something we don’t like.
We have completed several activities around this topic.
Firstly, created our share a hearts, which explained the pledges we made to stay safe on the internet.
As a class we picked two winning hearts, they were Zane and Kieran, and Jake and Luke.
We have also created posters that explain how to conduct yourself online. These included pieces of advice for other children if they were stuck on what to do if they saw something they didn’t like online.
The advice that we included was;
Don’t give out personal details.
Stop it, block it, flag it.
Ask before posting or sendingpicture of your friends, even if you are on it!,
Don’t be afraid to report someone.
We also looked at the SMART rules for being safe on the web. Smart stands for; safe, meeting, accepting, reliable and tell.
