We carried out an experiment to answer the question 'What makes yeast work the quickest?' We got busy making dough and made sure that we conducted a fair test by keeping factors the same such as the amount of yeast, the same ingredients, adding the same amount and temperature of water. Our interdependent variable was the temperature of the place where we left the bread to prove. We left some in a cold temperature (the fridge), some in room temperature (the classroom) and some in a hot temperature (an oven that had been heated but then turned off). We checked the bread every fifteen minutes.
It was easy to see that the room temperature worked best as each time we checked the dough was the largest. This was because the yeast cells are most active at room temperature. They cause sugars to ferment and generate carbon dioxide which causes the bread to rise.
With the rest of our day we baked some delicious rolls and when we cut them in half we could see the tiny holes formed by the carbon dioxide. Finally, we ate them. Yum!

History - Victorians - 2012
Towards the end of our Victorians topic we had a school day to discover what it was like to go to a Victorian school room.
We sat in rows and had to do a lot of chanting! We also had to write on to slates. Some people didn't do a very good job. They wore the dunce's hat!
We wrote out some well known proverbs such as 'children should be seen and not heard, silence is golden and manner maketh the man'. To experience what it would have been like to be left handed in Victorian times we all had to write with our opposite hand. This wasn't easy, two children even got the cane from Mrs Dolman.
We got to do some exercise drills but we weren't very good with our left and rights.
Eventually we got to have our Victorian lunch which consisted of jam sandwiches and a delicious Victoria sponge cake baked by Mrs Dolman.

DT - Enterprise Week - 2012
Last week was an exciting week. We designed and made a range of products to sell in aid of Sports Relief. We found out about this charity and how our money would be used for such a worthy cause.
Over the week we designed and made footballer door-stops and hair accessories with a London theme. We used our DT sewing skills to create some quality finished products.
We carried out some market research and then decided on a price to ensure that we made as much profit as possible. We designed and made posters to advertise our amazing products and created radio adverts for the whole school assembly. We then set our stall ready sell, sell, SELL!
We made £105 in total!
Also during Enterprise Week we thought about our aspirations for the future. We had a visit from Becki Houlston who talked about her job and inspired us to work towards our goals.
