Metals and Oxygen

 Aim: To make a metal oxide and observe the difference in properties of the products compared to the reactants. 

Method: - Light your Bunsen burner

              - Hold your piece of magnesium in the scissor tongs. Ensure you are holding onto the very tip on the magnesium. 

              - Place the other end of the magnesium into the Bunsen flame (At the top of the blue flame)

              - When the magnesium begins to burn, do not look directly at it, as the light emitted can permanently damage your eyes. 

Results: 



Discussion: The results were very good, as we were burning the magnesium the light was so bright and that means it turned out good. 

Conclusion: Our experiment did work and it turned out really well next time I want to try use more magnesium.

Social Studies - What have we learnt so far?

 What did the video encourage us to think about? 


That we have to protect our oceans and actually protect our sea life. 

That we have to try and help clean up rubbish so it doesn’t end up in our oceans. Everyday minutes more rubbish goes into our oceans and it's killing our whales, dolphins, turtles etc. When our whales reach the surface of the water for air they release these particles called phytoplankton and it releases oxygen for us to breathe. 85% of our oxygen comes from whales and if they die then our ocean dies then so do we. So much sea life gets washed up on our beaches because of how much plastic they are filled up with. 


What do you think about this?


That this is a huge problem and our generation needs to do something about it. Some of my own thinking is that we need to start putting rubbish in the correct bins, making sure it doesn’t get dropped or fly out of the bin. 


What is something that you could do to reduce pollution?


Put rubbish in the correct bins, don’t drop rubbish on the ground,

Metals and Acids

 Aim: To show that hydrogen gas is produced when a metal reacts with acid. 

Method: 1. Light your Bunsen burner or use a lighter. 

               2. Add your sample of metal ti your test tube, add 2ml of acid.

               3. Carefully invert the boiling tube above the test tube containing the metal and acid. 

               4. Hold the test tubes together for a few minutes, allowing time for the inverted boiling tube to fill with gas. 

                5. When you think the tube is full, your lab partner should light a wooden splint.

                6. Carefully, but quickly, tilt the boiling tube full of gas upwards and insert the burning splint into the mouth of the test tube.  

Results:



Discussion:

While we were doing the experiment we were trying to make a pop sound with the gases and the lit wooden splint. Once we took of the the top test tube we had to quickly put the wooden splint in the tube so as the gases impacted on each other it made a loud popping sound. In the first test tube we put metal and Sulfuric acid. 

Conclusion: 

If I were to do this another time I would hold the gases together for longer.
