Photosynthesis is the process by which the action of sunlight on chlorophyll in plants produces the substances that keep the plant alive. Plants make their own food in their leaves. Sunlight enters minuscule tubes on the surface, water enters through the stem of the leaves and air enters the leaf through pores on the underside.

This morning, our class found that if you mix vinegar with bicarbonate of soda and put it into a little container, then turn the container over, it will create a gas which will make the little container fly up into the air. The frist time we did it the little container landed on top of Top Cat’s head. The second time we did it the little container hit the roof the same as the third time we did it, but the forth time we did it the little container landed on top of lyds’ head.

This morning, some of us found out that if you mix vinegar and bicarbonate of soda and put it in a small pot with a lid then quickly tip it the other way around, it will fire up in the air. In our class it landed on Lyd’s head and Top Cat’s head!
We tried putting it in a cup and aiming it in diffrent directions.
Have fun trying to do the experiment!

This morning, we found out that if you mix vinegar with bicarbonate of soda, it will create a gas.
We then put it in a little tub, waited and it shot up into the air. Because the gas inside the tub was pressurised, eventually it pushed the lid off the tub.

Your heart contains muscle within the walls of it. The muscles squeeze the blood around your body. Then, the blood flows through your blood vessels to every part of your body. To be on the safe side, the heart is protected by the rib cage. Every time the blood circulates from the heart out to the body, about 20% (one fifth) passes through the kidneys. The kidneys filter out some of the waste before the blood heads back to the heart.

About three hundred years ago when sailors went on ships at sea, they couldn’t take fresh fruit and vegetables because the refrigerator hadn’t been invented then.So, instead they soaked meat in salt (this was called salted meat.) Most sailors that eat salted meat, get a horrible infection called Scurvy. The doctors were confused and thought of a way to cure Scurvy. Eventually they came up with limes. So they gave the sailors limes. Limes helped because they are full of vitamin c.

It was a chilly morning so the radiators beneath the curtains were on. To stop the sun shining on the IWB (Interactive White Board) we had some of the curtains closed.
When we returned to the classroom after break, we noticed that the curtains were billowing out into the room.
Why was this? We had a discussion. Could it be wind? No, the windows were closed. Could it be the heat ‘pushing’ the curtains? Hmmm…
TeddyBear Lover came up with part of the answer; the warm air was expanding.
Combine that with the fact that hot air rises and there you have it!
Hot air was rising from the radiator and getting trapped behind the curtains. Because the trapped air was getting warmer and warmer, it was continuing to expand (take up more space), pushing the curtains into the room.
I hope the jotted diagram helps.
So, keep your eyes open and if you see something unusual,
ask that big question; WHY?

How many senses does a human being have?
No, a human has more than five senses.
A Greek gent, by the name of Aristotle, said that there were five – but he is a couple of thousand years behind current scientific thought.
In today’s scientific community, it is agreed that there are at least nine human senses. There are many more possible senses upon which scientists cannot agree.
So, what are they?
Other contenders are the sense of hunger, thirst and the sense that a visit to the loo is needed very soon! A sense of humour, however, will never be included.
