Novel Study Part 3

This is the final part of the novel studies for "Children Of Blood And Bone" by Tomi Adeyemi.

It was a good book but had a intense cliffhanger ending.

Velocity Equals Distance Divided By Time

In science we have been looking at forces of motion, a.k.a. speed and stuff. We created land speeders to look at speed using the formula of velocity equals distance divided by time. The distance was 9 meters and the time was 11 seconds meaning the speed was 0.8181818182 ms-1. We may have been able to make it go faster with a larger sail.

Novel Study Part 2

So the novel studies doc wasn't too long or too laggy our teacher split it into 3 parts. This is the second, the third is still to come.

The Stone Age

For social studies we were tasked with researching a time where man made an advancement in tech. My group chose the stone age. The stone age was when humans began to make tools out of things like rocks, sticks, and bones. Here is a slide show we made about the time:


We also had to try and recreate something done at the time, we chose to do art, an partial insight into their lives.
Pictures to come soon...

Throw The Egg From Up High

Today in science we had been tasked to remove the fall damage from an egg by means of insulating it. We surrounded it with foam and soft stuff, wrapped it in bubble wrap, and stabbed with skewers to make legs. Then we added a parachute, all in all the egg lived. Now the complicated bit (ask your father) the egg had a weight of 400N while the egg and lander weighed 1053N using the method of F=ma (force = mass x acceleration).

Career Study

For social studies we have been looking at careers and how tech has changed over time. With all that happened with ******* lot's of job losses have happened so we are learning to get one.

Money Math

For math we have been learning about money and percentages around increasing and decreasing wages, prices or salaries. It is like 50% off sales but a bit more complicated because maths likes to do that. You can increase a price by a certain percentage by typing: 1.percentage x price. You can decrease a price by typing: 0.percentage x price = ans _ 100 - ans. The end.

Golden Coins

In science I was given permission to conduct an experiment of my own accord based off an experiment we did in class around giving a 10c piece a gold coating.

Aim: To test which New Zealand unused and modern coin contain copper.

Equipment: Beaker, Bunsen burner, Tripod, Heatmat, Cold tap, Sodium hydroxide, Zinc powder, NZ coins, Gauze mat.

Method:
1. Heat coins in sodium hydroxide until steaming, then turn off bunsen burner.

2. Add zinc powder and stir for a while until water starts clearing and the coins should be silver, clean coins.

3. Hold coins in fire, desired result is a gold sheen, cool in water.

Results:

New Zealand 1c - yes
New Zealand 2c - yes
New Zealand 50c - yes
New Zealand 5c - yes
New Zealand 10c - yes

New Zealand old 10c - no

New Zealand 20c - no
New Zealand half penny - not really
American 1c (bc I had one) - yes
Air Force Museum flat pressed 10c - yes

Observations:

There is a golden colored alloy called brass, brass consists of zinc and copper. The coins with copper in them would combine with the zinc powder to cause the coins to be coated in brass.
