Week Four in Hoy Class

Class four started the week with a very exciting and entertaining trip to the Stromness Academy.  We went to watch a show as part of the Science Festival called Disgusting Digestion.  

It told us all about our bodies and how the different parts of our bodies work together to help digest our food. 

There was a cracker eating competition to show how our saliva helps to break up food ready for digestion.

Then we were shown how the digestive system works using a gruesome experiment!

Class four also had a visit from another team of experts from the Science Festival.  This time it was about electricity and magnetism.  

We were shown lots of interesting and exciting tricks and experiments using different types of electricity.

Some of us used hamma beads to practice our spelling words this week.  

We have also had a visit from the school nurse this week.  She came in to tell us all about head lice and how to wash our hands properly to help keep our bodies healthy.  We learnt how to check our hair for headlice and how to treat them if we did find any.  

We then did a sneeze experiment using glitter to show the bacteria produced when we sneeze into our hands.  We then shook hands with each other and touched various items around the classroom.  We were very surprised to see how much glitter (bacteria) spread onto everything we touched.  

We decided it would be useful to know how to wash our hands properly to stop the bacteria spreading around everyone.

We used a special UV gel and a light box to see the mess on our hands,  then we washed our hands using the special technique shown to us by Alison.  

Some of us realised how difficult it was to actually wash all the gel off our hands!!

But we managed it in the end!!

Class four have also been learning about the human brain this week.  We found out about the three main parts of our brain and what each bit was responsible for.  

We then got ourselves into groups and began making a model human brain using various materials. 

We had to ensure that it was clearly labelled with the three main parts and an extra challenge was to have what each section did labelled too!  Watch this space to see our finished brains.
