This week was a good fun one. In our first lesson we had our last adjustments to our kart and i just adjusted the glue to make sure the wire at the front stuck. We also discussed what to do for our next assesment. Zara wanted to build some sort of wood work and we all wanted to make rockets, though I had allready done that in year 5 so I wasn't as keen. But then I had the idea to make a catapult (partly because I was thinking of Lord of the Rings and other because my brother had just found a nerf gun). But anyway, the idea was accepted and everyone seemed keen.

The race day, well I got kicked out on the first round -very close through - and I lost to Amber who won so, well, luck of the draw. I was on timer and it kept me busy so I was happy.

Last lesson we discussed more on our new unit which is building a trechuet (catapult). It looks really exciting and I am actually really keen to do the history about it because medieval history is pretty much my favourite era to look at.

I will be working with ruby and we started researching designs for our machine and we have found some variables in the design

• wheels or no wheels (we already know from a video that Mr Ward showed us that it works better with wheels because it increases the thrust of the object fired
• The holder can be either a spoon shape, a "sling-shot" type shape, of a netted basket
• How much scaffolding is on the model
• what is used as the weigh (usually it is a box that the weight could be changed)
• length of the rope
