Primary 4/5 making the  most of the snow on Tuesday morning, while it lasted!!!!!

Primary 4/5 are back at school working hard after the winter break. Their new topic is ” The Human body”.  Here they are working in co-operative groups on grafitti boards to establish what they know already about the topic and what they want to find out about it.  They knew quite a lot and they have learned lots of new things already!

We have also started our wider achievement afternoons this term. In the p 4/5 class some children have chosen to do craft work.  Here are some p 3/4/5 children weaving baskets or making cross stitch pictures.  Thank you to Mrs Tregonning for helping out!

Our topic this term is castles.  We have been learning about technology in the middle ages.  First we revised some work on energy and forces from last year.

Then we did some experiments to learn about levers and how they are used to do work.  We learned that the longer the lever the less effort needed to lift a heavy load but you can’t lift it very far.  If you put the load on the long end and the effort on the short end you have to use a lot of force but you can lift the object higher.

There are three kinds of levers, a first class lever, a second class lever and a third class lever.  First class levers are the most efficient kind then second then third.

We have been learning how castles were attacked and defended.  Gatehouses made the entrance to the castle stronger.

Drawbridges could be pulled up when under attack.   We made model gatehouses with working drawbridges.  A drawbridge is a third class lever.

Siege machines like the trebuchet were used to attack castles.  We made model trebuchets.  A trebuchet is a first class lever.

Then we enjoyed testing our trebuchets.  They worked really well!! A trebuchet is a first class lever.

We did research on castles and made some super posters which are on our class wall.

We had a great time visiting the Lerwick Power Station as part of our electricity topic.  Here are some photos of things we saw and found out about while were there.  We learned a lot of interesting things!

Mr Rose came to visit to help us find out about and understand what conductors and insulators are in relation to our electricity topic. We had great fun and came to a conclusion about what each item was.

Last week we had a visit from the Bodyworks people and took part in workshops called Disgusting Digestion.  Here are some photos. We discovered the journey that food makes from the moment it goes into our mouths until we digest it and then get rid of it through our body waste.  It was pretty disgusting!

In the afternoon we took part in a workshop to look at how other parts of our body functions.  We found out about heat imaging and where our bodies hold the most heat.  We found out how our brain multitasks to help us do lots of things while controlling other things. We looked at healthy lungs and unhealthy lungs, bones and x-rays, organs within our bodies and many other things.  It was great fun and very interesting!

We were learning about 3D shape. We had to make some shapes using different material. Working together in pairs we had to make a range of different shapes. Some were easy and some were more difficult. Thank goodness we had a partner to help us!

We had such a busy March with lots going on. Sorry we’ve only got our assembly photos up now.  We enjoyed every minute of our topic and finding out about food.
