Volcanic Activity in Room 5
We made a volcano today. We got an acitmel bottle and put newspaper round it so that it looked like a volcano, and a tray underneath in case we made a mess.
Fire Extinguisher
We made a great fire extinguisher today. Teacher lit a candle and carefully put it into a big glass. This is our fire. Next she put in a few spoonfuls of baking powder. She was very careful not to put the powder on top of the candle.
One of the boys held the funnel while teacher put a little vinegar on top of the powder. The powder and vinegar mixture began to fizz. We heard that when you mix vinegar and baking powder together, a gas called CO2 or Carbon Dioxide (bad air) is made. This gas is heavier than air, so it sits at the bottom of the glass. When enough CO2 is made, it pushes the Oxygen (O2 good air) up higher in the glass. Now that the candle can't reach the O2, the flame goes out.
We also learned that we breathe in Oxygen and breathe out Carbon Dioxide. Plants and trees do the opposite - they breathe in CO2 and breathe out O2. That is why it is so important to have lots of trees planted around us, and lots of trees in the world.
There is Carbon Dioxide in fizzy drinks too. When we drink it the gas goes into our tummies. If we can't get it out of our tummies, it gives us a tummy ache. When it does escape from our tummies it can go up (burp) or down (fart). Both of these seem very rude, but they are natural. We just have to try and not upset the people around us by being too noisy or smelly, and always say "excuse me" if one slips out. We have often seen mammies put their babies on their shoulder and pat their backs to help them burp. They must have gas in their tummies too!

Tissue Goal
There is a lot of talk of soccer at the moment. Teacher had some interesting science to show us today that looks like a soccer trick. Teacher made a small ball out of tissue. We had to blow it into a bottle goal. It was much much harder than it looked.
Making a spray
We use lots of sprays in our lives. Today we made our own sprays. We got a cup of water and put a straw into it. The straw was cut so it hardly stuck out of the cup at all. We know that there is water and air in the straw. Next we were given a piece of straw each. We used this to blow the air from the top of the straw.
Straw Oboes
We found out today how to make straws into musical instruments. We squeezed the top of the straw, then teacher cut the top in the shape of a pencil top (or mountain). We could get the straw to sing by holding it between our lips and blowing.
