What is Reggae?

While doing this research project, we also worked on a 30-second performance of Three Little Birds by Bob Marley. I performed with Jaime and Sam, and I think we did alright. I played the guitar and managed to do okay, I fumbled on a few chords but I kept on going and it sounded alright. I think it would sound better if I didn't play the guitar. I think that the overall performance sounded alright we did well!

Model Atoms

Aim: To make a model Atom.

Equipment:
- Tape
- Beads
- Blue Tack
- String
- Paper

Method
- The first step when making a model atom is to figure out the number of electrons that the atom contains. The element that I chose to do was Boron. There are 5 total Electrons in total so I had to draw 5 circles in the shells.
- The second step was to create and cut out the shells for the model atom. I needed to cut out two shells so I drew out two shell shapes and then proceded to cut them out for the model. You don't need to make them exactly perfect but it is nice to have them even.
- The third step was to draw the electrons on the shells. I needed to draw 5 so on the smaller shell in the middle, I drew a group of two circles. Then on the next shell, the larger one, I proceeded to draw one singular circle and then I drew a group of two circles next to another.
- The fourth step in making a model atom is to create a nucleus, in the centre, you can see the nucleus has beads representing the Protons and Neutrons that your element has. My element had 6 Protons and Neutrons all together so I used three white beads to represent Protons and then green beads to represent Neutrons. I used three of each bead. After that, I just cut some string and stuck it all together.
- Finally, I created an element sign and made it look presentable.

Discussion 
So what are these Protons and Neutrons and all this smart sounding stuff? So Neutrons, Protons, Electrons, Nucleus' all make up atoms. What do atoms do? ATOMS MAKE UP EVERYTHING!!! It took our class a long time to understand this, but Atoms make up every single thing on this lonely universe. Every single plant, every single person and every single potato on this earth. Everything on this earth is made up of atoms. But what makes up an Atom?

Protons and Neutrons 
Protons and Neutrons are in the centre (Nucleus) of the Atom. Protons are positively charged particles found within an atomic nucleus. The number of protons in an atom defines what element it is. The number of protons is the atomic number in that Atom. Neutrons are uncharged particles found within an atomic nucleus.

Electrons
Electrons are the primary source of electricity in solids. They are particles with a negative charge of Electricity and are found in all Atoms. These Electrons orbit around the atomic nucleus.

Neutralisation experiment

In science, we have been learning about Acids and Bases. Chemical reactions occur when you mix together an Acid and a Base together. The base cancels out the effects of the Acid. This reaction is called Neutralisation because a neutral solution is made if you add just the right amount of Acid and Bases together. Chloe, Jess, Molly and I did an experiment exploring Neutralisation.

Neutralizing Acids and Bases

Aim:
To observe a neutralisation reaction by neutralising Sodium Carbonate using Hydrochloric Acid.

Equipment:
- Test tubes,
- Test tube racks,
- Sodium Carbonate,
- Hydrochloric Acid,
- Pipette,
- Universal indicator solution'

Method:
1. Add approximately 1-2mL of Sodium Carbonate into a test tube and place the test tube into the test tube rack. Add 3-5 drops of Universal Indicator solution.

2. Using a pipette, add Hydrochloric Acid drop by drop. Be careful because adding even a small amount of extra acid can mean you miss the neutralisation part.

Results: 

Here you can see that Chloe, Jess, Molly and I have created a rainbow using the Acids and Bases. The Red, Orange and Yellow liquids are all acidic. The red one has the strongest acidity. The two Blue liquids are both basic. The green liquid is the neutral liquid.

Discussion: 
During the experiment, we attempted to balance the colours in the Ph levels. The strongly acidic liquids are red and the strongly basic liquids are of a dark Blue colour. The universal indicator shows which level of the Ph scale it is. While doing this experiment, we quickly figured out that balancing these solutions is quite difficult. You have to mix the right amount of Acid and Base to balance the solution, then you add the universal indicator to see what level it is on the Ph scale. It is difficult to balance it perfectly as it can switch from one colour to another with a single drop of acid or base.

Conclusion:
In conclusion, our experiment was successful as everyone in our group somehow managed to neutralise the solution. We actually had a little race with Jessica as the winner. After that, Mr Heath challenged us to create a rainbow with the solutions.
