Yesterday (Tuesday 21st March) Primary 5 had a wonderful science STEM day and made cornflour slime. The children all enjoyed getting involved with the experiments and trying things out and following the instructions to make new things and to show changes in colour and changes in state.
The children found it quite tricky to mix the cornflour and water and had to work hard to combine the two using lots of muscle power.
Eventually, when the consistency was correct the pupils chose their preferred colour for the slime.
adding a little water didn’t work well and we had to add more
cornflour and water mix to create a substance that is hard when you tap it and turns runny when you handle it.
Yesterday (Monday 20th March) Primary 5 were exploring these questions in some depth.
Firstly we came up with our own theories regarding the reasons(s) why the Titanic sank which included;
the weight if it was balanced
the mass and density of the Titanic made it float
The turbines and propellers made it float by spinning
it was made with enough density
the funnels had air going out
it was made of metal
the shape of the metal allowed it to float
there was a lot of air on the Titanic
it was very spacious – air on board
lots of hollow spaces
I am sure you will agree that Primary 5 really thought very hard at this and did very well at giving reasons and when questioned further were able to justify their reasons.
Today we had a guest in the class to help us answer this question and allowed us to have a deeper discussion and develop our understanding. They were all so engaged in the lesson and the questions that the class were asking were just fab!
Today we learned that the Titanic stayed afloat through buoyancy where the upward thrust of a force allowed it to float – when something is placed in water it will sink until it moves enough water to support it.
The reason the Titanic sank = it hit an iceberg and ripped a hole in its hull. water then poured into the hull and the ship became too heavy – there was not enough support or upward thrust to help it float.
Why did it sink diagonally and why did it snap?
Think about a seesaw – more weight at one end will lift the other up, so one end of the Titanic came out of the water. The end that was in the water was filled with water and pulling the ship down. The end that was in the air did not have the support from the water and so became heavy (because it was made of metal) and therefore snapped.
Primary 5 really did a brilliant job today of digging deeper into these questions and have developed a good understanding of them now. Their questioning and reasoning was great!
Primary 5 had a fabulous time learning all about space, and in particular, the Moon Landing.
They put all of their knowledge to use and created newspaper articles describing the Moon Landing and enjoyed creating their own headlines.
The effort they put into their reports was excellent and they were all keen to learn more about it.
I am sure you will agree that their display looks lovely.
Primary 5 have started their journey into space through their topic. We have discussed what we already know and what we would like to know. We added this to our floorbook and we can’t wait to add lots more information and facts to it as we go along.
What we know:
space has no gravity
Neil Armstrong was the first man on the Moon
there are craters on the Moon
there are 8 planets
the Earth was made by the Big Bang.
What we want to know:
what are the planets made of?
more about all the planets
can we live on Mars?
when is the next eclipse?
Are there more than 2 galaxies?
How hot is the Sun?
How big is the Sun?
Why are there craters on the Moon?
We can’t wait to share what we learn about space with you.
Primary 5 would just like to wish everyone a happy New year and we hope that you all enjoyed your break over the festive period.
Primary 5 have been sharing their stories about Christmas with each other and even managed to write a recount of Christmas day.
They have also been looking forward to another fun- filled and jam packed term and have been busy creating targets for their curricular areas that they would like to work on and have already managed to get a new display up in class.
We are looking forward to sharing all of our activities and news with you over the coming term.
