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.
