Telephones

Technology through the ages.

As part of our topic on ‘Technology through the ages’ we looked at the invention of the telephone.

We learned about the life of Alexander Graham Bell  including where he lived and when he was born. We discovered that he invented the telephone in 1876 with the help of his assistant Thomas Watson.

We made string telephones to see how the sound vibrations can pass from one person to another.

We discovered that when one person talks their cup vibrates, the sound energy from these vibrations passes along the string into the second cup which also vibrates. These vibrations pass through the air particles into our partner’s ear and they can actually hear what we are saying!

We experimented by using longer pieces of string, by whispering, by leaving the string ‘loose’ instead of ‘tight’ to see if there were any differences.

  

Maths

P4 Outdoor Maths

Today the P4s got together to complete some maths work outside. We worked in pairs and we had a sheet with lots of different questions on it.

Firstly we had to find right angles, and shapes in our environment,next  we had to time how long it took us to walk around the school – then estimate how long it would take us to walk round three times.

We also had to work out some fractions and find examples of tiling and symmetry.

We had to measure using strides and hand spans – we worked out that our answers were different because we have different sizes of hands and strides.

It was interesting to try to use our maths skills in different places, some of the questions we found quite easy but others were more tricky. We were glad that we were working in pairs this time!

On Tuesday  21st May  we had a STEM workshop with Emma.  At first we watched a video  about not throwing away plastic because it affects wildlife and the air. Then  we spoke about jobs and more, and how ROVs can clean salmon cages. After that we went into the canteen and tried programing Lego mind storm robots. I was in a pair  with Joe but our robot didn’t  work so we got a new one and it worked.

First we  had to try and make our robot move in a square but we couldn’t do it, it was tricky to programme the robots with the Ipads! Then we had to put a piece of Lego ( our ‘plastic rubbish’) under some chairs with the  arms on the robot, we kept working at it and we did it! We enjoyed the workshop.

Co-op Groups

Skeletons

Leave a comment

Our topic this term is ‘The Body’ and we have begun by learning about the skeleton.

We discovered that babies have 300 bones but as they grow some bones fuse together until they end up with 206.

We also found out that our longest bone is our thigh bone: the femur.

Our task today was, working in our co-operative groups, to make a child-sized human skeleton using paper cut-outs. We had to look at our posters to check we were gluing everything in the right place. We also had to label some of the major bones correctly.

We had to make sure we were following our ‘group norms’ and working well together.

We had to complete the task in less than 45 minutes! The winning team were given a special prize.
