Happy New Year and welcome back class 5 and your families.
We began the new term with a whole school science experiment. The penny boat challenge. Mrs Casewell challenged the school to see how many pennies we could get on a floating boat made from silver foil. Additionally, she challenged year 5 to explain the science behind floating and sinking and why our winning boat won. She chose us as we had just completed our science topic on forces.
Quickly, class 5 realised that the winning boat would need to have a large, flat surface area. Well done to the winner of the challenge in our class who was Elekwachi.
In assembly, a team of class 5 scientists reported back to the school that there were two forces acting on this science experiment. The first force was gravity. Gravity was trying to pull the tin foil and pennies downward. The second force was buoyancy or upthrust which was pushing the boat toward the surface. The team explained that the gravitational force was determined by the weight of the tin foil and the weight of the pennies in the boat whereas the force of buoyancy was the weight of the water displaced by the boat (this is the water that moves out of the way when you get into the bath!). We discovered that a boat full of pennies will continue to float as long as the force of buoyancy is greater than the force of gravity and you place the pennies carefully into the boat so it does not tip over or leak .Therefore, we found that the best design for an aluminum foil boat was to try to make it cover as much area as possible.
This term we are studying the poem Beowulf. We have written invitations to the opening of King Hrothgar’s new mead-hall, Heorot, and with a partner we have written and performed a news report of the slaughter of the Lords sleeping in the mead-hall by the vile monster Grendel. Every news report was written and delivered superbly. Unfortunately, the snow stopped us from voting for the best news report which I was going to video and add to my blog so watch this space to see our amazing news readers!
Just a quick reminder, class 5 will be swimming every Tuesday (for 4 weeks) from 17th January so please remember your swimming kit. Our P.E. lessons this term are gym on Wednesday and Street Dance on Friday.
