Rube Goldberg

                                Rube Goldberg 

At the start of the term we all decided to do a fun learning task so we did the rube goldberg machines! Ours went down a ramp and hit these two pens that hit some dominos. And they hit the plastic bottle that rolled and hit the ball that hit the bell! So ours wasn't to complicated but it worked. It took a lot of thinking and working out we had to think about if it was going to work or not and what things we would have to get and who would get the objects for the rube goldberg.

 The hardest part was to line up the dominoes because they kept on falling over and we had to keep redoing it. We usually got ours on our first try but when we had to show it to the class we seemed to do it badly on our first try. So we did it again and it worked that time. I think it was a really fun experiment and we worked ok as a team. So I think it was a success!

What is body odour? Are you the smelly one in the room because it is some one and it is not me. 

It may not be you who is super smelly it could be you annoying brother your mum or even your stupid uncle who only washes once every 20 years!!!!!! But if it is not you annoying brother your mum or your stupid uncle that only washes once every 20 years it is obviously you.

Now some say BO is bacteria growing on your skin but realy it is bacteria breaking down protein into certain acids. it is the bacteria breaking down that causes that unpleasant smell.

So have you thought of getting rid of BO because it doesn't seem like it so here are some tips .

Start off by having a shower or bath daily, where clean clothes, when you go to sport bring deodorant with you.

So do you still want to be the smelly one in the room because im pretty
