Science

On the topic of Forces and Motion in Science, We learned how to calculate speed, force, distance, and time using different formulas and learned different units.

 Force:  F=ma

              = m(mass) x a(acceleration)

              = n N

     

 Speed:  V= d/t

               = d(distance) / t(time)

               =  n ms-1 ( meter per second)

 Distance: d= v x t

                 = v(velocity)xt(time)

                 = n m

Time: t=d/v 

          =d (distance)/ v(velocity)

 We investigated how fast cars are going on Carmen Road, whether they were speeding or not. 

 

We first used a stopwatch to measure how fast they were going and listed down on my book. We found the average time by adding the time and divided them by 10. Then to find out the m s-1  we divided the time to 50. and added them and divided them by 10 to find out the average m s-1. I didn't finish working out my km hr-1 so I don't have an answer. 

   

  

                

Maths Blog

  This week in maths I have learn't about the two types of tax: income tax and GST( good and services tax)

Income tax:

 (___ )/ 100 x (____) = ----

 The amount you are paid by your employer is your gross pay. The amount you actually get after income tax is paid is, called your net pay.

GST:

 There are two types of GST. GST-exclusive ( what the retailer gets) and GST-inclusive ( what the customer pays). 

  

Careers Inquiry

 In Social Studies we have been learning about different careers. We also completed a booklet our teacher gave to use. We have given a booklet a sheet where we were assigned a fake job to help us answer the questions and teach us how career life works. After we have completed the booklet, we had to find out what careers we are interested in. I was interested in being a digital artist or animator. Then we had to do research about the job we are interested in and fill out an inquiry for careers document. 

Circuit

What is a circuit?

A circuit is a path where electricity travels. There are two types of circuits: Series and Parallel circuit. 

A Series Circuit is where there is only one path for the current to flow whereas a parallel circuit is where the current can flow into different paths as shown in the image on the right.

What is Voltage? how does it differ in series vs parallel?

A voltage measures how much volt a current carries. In a series circuit, the volt is shared among the components while in a parallel circuit, the current has more branches to follow. It carries the same amount of volt and does not split.

(series)                                                     (parallel)

What is Current? How does it vary in series and parallel?

Current is the flow of electrons in a circuit. It is measured using a device called an ammeter and the unit of current is an amp. 

In a series circuit, the current is the same and isn't shared whereas in a parallel circuit the current is shared.

Financial Literacy

This week in maths we started our topic of Financial Literacy. We learnt the difference between Wages and Salary. Wages is the money earned per hour and salary is the fixed amount of money per year. We also learnt about overtime pay and how to use and make a wage sheet using google sheets.

Street Art

In Art, we are looking at Street Art. We are to choose a photograph of street art and blog about it.

 I chose this image because it caught my eye because of all the vibrant colours and the words.  This graffiti was created by a bunch of street artists. Lots of different artists from all over the place went in and collaborated to create this amazing artwork.

  I like looking at street art because it sometimes helps me with boredom during road trips so looking through street arts makes it a lot more enjoyable. I also analyze street art sometimes just because.

Date: 2014 Rise Festival
Artist: Multiple artists


I like this street art because it looks cool. This is a graffiti of a ronin.

The Benefits of Controlled Burning

 Title: 'How Controlled Burning Benefits us'

Introductory statement: Controlled burning is when a "wildfire" is set purposely and planned which is beneficial for the forest management. They carefully plan it and have firefighters thoroughly watch the flames. There are two types of controlled burning: broadcast burning, which involves lighting fire in an area of land, while pile burning is when leaves, branches and other debris are cut snd burnt when weather conditions aren't safe.

Arguments: Why is it a good thing? I believe that controlled burning is a good method, because not only has this method been used for a long time, It also is helpful to the environment. Controlled burning or prescribed burning is set when there are wildfires happening to prevent the fire from spreading larger and faster. The fire also helps return the nutrients in the soil. Controlled burning is also used to exterminate dead trees, branches and other debris which frees up space to help young trees and new plants to grow in. This is how it helps with the environment.


  How does controlled burning work? Interestingly it already states it in the name. It basically is just controlled burning. First, managers plan and draw up a plan, which includes how big, what will it burn and what they hope to accomplish with the fire. The managers also plan how the fire will be set, how to inform the public and the equipment needed. They would also check the weather and the environment's state.


  How does it affect wildlife? The managers choose carefully when they burn based on current conditions, and many controlled fires are slow-moving giving the wildlife a chance to find safety by leaving the area or finding shelter. Burn sites are divided into smaller plots with some land left unburnt, giving space for wildlife to go. Very little injuries happen during prescribed burning as most animals are able to escape but if there are animals that were burnt, the people managing the fires would look around the burnt area looking for injured animals. Prescribed burning helps maintain healthy habitats and restores and strengthen plants.

Conclusion: I strongly believe that controlled burning or prescribed burning benefits us as it can stop wildfires from spreading larger and faster, It's planned well and help maintain healthy habitats. One example is a prescribed burning occurred in the ponderosa pine forest in eastern Washington, United States to restore ecosystem health and another example is in southeast Australia which began at the beginning of September which was rapidly spreading, so they used prescribed burning to stop the spread of the bush fires.
