On Monday the 2/9/24, my group had received a beaker of copper sulfate. Then we received three nails, we sanded 2 nails and left the nail that was galvanised. One of the other nails were coated in vaseline and the other was left sanded. Then we put all three nails into the copper sulfate.

3/9/24. We took a look at thee nails and the nails were corrosed.

Today in science we tested for the three common gases.

H/ Hydrogen – Makes a pop/squeak when a burning splint is held near it

CO2 – Puts out (Extinguish) a burning splint

O2 – When you blow out a splint and it’s glowing. A glowing splint.

We learned to decompose reactions

Explain decomposition reactions.

Reactant + Reactant = product or Reactant = Product + Product

CaCO3 = Calcium = 1, Carbon = 1 and Oxygen = 3

We burned a white powder that was soft and had no smell called calcium carbonate. After we burned it, it turns into half black and white powder.

When we heated the CaCO3 (Calcium carbonate) and held the test tube above the Bunsen burner, then after a while we held a splint at the top of the test tube, after a few tries we realise that the flame kept going out from the carbon dioxide.

Carbon dioxide was given off.

Last week Friday, we made Hockey pokey for science. I did not stay long because I had a sore stomach that morning. But, to start the day off we were to “Explain the ATOMIC structure of an Atom.”

We learned that the rings on the outside of the nucleus is called the “Valance rings.”

Protons give a positive charge = +

Neutrons give no charges = 0

Electrons give a negative charge = –

Co2 = Carbon dioxide, there is 3 total atoms but only 2 types of atoms

H2Co3 = Hydrogen bi – carbon, 6 total atoms but 3 types

This is converting lengths, you need to learn this for college and learn it for when you are converting

Whanganui hit-and-run A child around 6 years old was walking home with a group of friends. He was crossing the road (Cornfoot st) near Rangiora St.

Whanganui police have tracked down the vehicle and person allegedly involved with a hit-and-run and he left the child on the ground critically injured.

The 6 year old boy was walking home with a group of friends at 7:45pm on Saturday when he was struck by a vehicle while crossing Cornfoot St near the Rangiora St intersection in Castlecliff.

“Whanganui police have been able to identify and locate the vehicle and driver in relation to a hit-and-run in the Castlecliff area on Saturday evening” a police spokesman said “Police want to thank the public for the information they provided and the inquiries into the incident remain ongoing”.

Police are still interested in receiving any CCTV footage from anyone in the area of a small blue hatchback-sized car.

Yesterday,police appealed to the vehicle driver urging them to do the right thing.

“The driver of the car did not stop, and the boy was transported to the hospital in a critical condition. The vehicle was described as a small,hatchback-sized,light blue coloured car”.
