Yesterday Primary 6 were invited along to Broxburn Academy for their annual Science and Technology day. We were all very excited as the hall was packed with loads of children from other local schools and some strange looking experiments and stations.
The first station we visited was called Hovercraft CD. To make these we had to blow up a balloon and attached then to CDs with a closed bottle cap on it. Next we put them on the floor and opened the bottle cap. Since we had opened the bottle cap, the air from the balloon escaped which made the CD slide along the floor.
Next was Outrageous Ooze. First we were asked whether we thought the ooze was a solid or a liquid, we all thought it look like a solid. The third year pupils asked us to make a snowball out of the ooze but as soon as we scooped some up it melted away. Next we were asked to hit the ooze and amazingly it didn’t splash but if we gently put our hands into the ooze they sunk. After trying out different experiments with the ooze we found out that it was a solid and a liquid! This is called a colloid.
The third station was called Fizz Pop Rockets, for this one we were given safety goggles. We had to fill a little tub with water and stick a fizzy tablet with onto the lid. We then placed the tub upside in a tray and started our timers. After a few seconds the tub flew up in the air with a pop! This happened because the tablet dissolved in the water releasing a gas called Carbon Dioxide.
The fourth station was microscopes. First we had to pick out some pond weed and put it on a glass slide. Then we looked through the microscope to see the plant cells. After that we were given another strip with brain cells to have a look at.
The second part of our day was all about CDT (craft, design and technology). We had to design and build a skyscraper. First we all planned out a design and then used the straws and tape to build our structure. It was a competition to see who could build the highest structure. The highest tower was over two metres!
After lunch we had a big quiz. Most of the questions were to do with what we had learned throughout the day. The other questions were to do with science and technology. Sadly, St. Nicholas didn`t win but we had a great day!
