Science experiments

On the 18th of October, we did our first science experiment (Practical). For this experiment we were going to heat ice until it started boiling. We got into groups and we had to get the equipment for the experiment.

• Beaker
• Thermometer
• Tri-Pod
• Bunsen burner
• Ice
• Timer

First we had to get all the equipment and set it up. we got some ice and put it in the beaker and then we used the thermometer and checked the temperature of the ice before we started. We then turned the Bunsen burner on so you can still see some of the safety flame and started to heat the ice. Every minute we have to check the temperature of the ice / water and write it down so then we can turn it into a graph later on. The temperature stared going up slowly but it eventually got hotter and hotter by the minute. There was eventually no ice left and and it was time to put all the information together. We made the graph and all the information. That was our ice melting experiment.

On the 24th of October, we did our second experiment. For this experiment we were putting a Potassium Permanganate Crystal into a beaker fill of water. For this experiment we were paired up and we got our equipment. 

• Beaker
• Potassium Permanganate Crystal
• Water
• Straw

First we got our equipment and set it all up. We filled our beaker up with water and we got our Potassium Permanganate Crystal, Straw and we went back to our work area.  We used our straw and we put the Potassium Permanganate Crystal through the straw and it slowly drop into the water. When it touched the water some little shards off of the Potassium Permanganate Crystal went through the water. As the Potassium Permanganate Crystal was sitting on the bottom of the beaker, the water was going magenta colour and the water on the bottom was going a midnight purple. The Potassium Permanganate Crystal was slowly dissolving and there were air bubbles forming around the Potassium Permanganate Crystal and when they were let off some of the colour went with it so it looked like strands of spiderweb. That experiment was really cool and it was a really informative experiment as well. we had to write down what happened and what we thought the outcome was going to be.
