Biosecurity

Today we learned about Biosecurity we read about it then we watched a video then after that we had to write a summary about it then put it in a fake newspaper but I couldn't put it on the blog for some reason. 

What is Biosecurity? 

By DAVLYN 

Biosecurity, what is Biosecurity well Biosecurity is a type of security but it’s not your normal security that you would find at a bar, Biosecurity is a security that protects your environment from biological threats like a disease. New Zealand is taking action to prevent unwanted organisms from harming the economy, natural biodiversity, or the health of the New Zealand public. The Department of Conservation affirms “Biosecurity is about keeping New Zealand is free of unwanted organisms and for controlling, handling or exterminating them should they arrive in the country, to prevent or decrease any harm, and defend and protect the land, water, industry, and people of New Zealand". Why is Biosecurity important, Biosecurity is critical because it stops unwanted organisms from coming into our country, unwanted organisms are dangerous because they could form a disease. Types of diseases that could and have already come into NZ are foot and mouth disease and mad cow disease. Biosecurity doesn’t only stop diseases it also stops pests such as possums, goats, deer, wallabies, rabbits, ferrets, stoats, and weasels, but it doesn’t stop there Biosecurity is trying to keep dangerous plants out too like Scrambling lily or Devil’s tail.

Maths: WALA: The diameter, radius, circumference of a circle

Maths results

Today we answered some questions online and at the end, we played a cool little bonus math game. The questions were about circles, you're probably wondering what did you do with circles. Well to answer that question we had to try to find the circumference and the area of the circle. For example, to find the circumference we have to know the most important part of finding the circumference and that is pi, pi is approximately 3.14. So since you know what pi is I will tell you what the diameter and radius are, the diameter is a line halving the circle and the radius is half of the diameter. now you know what pi, radius, and diameter now we can find the circumference. So the first thing to do is to multiply pi from the diameter, or because the diameter is 2 times the radius you could do radius times 2 times pi. For example, we have a circle with a diameter of 10 meters, to find the circumference we need to times the diameter which is 10 by pi which is 3.14 then we get 31.4, so the circumference of the circle is 31.4 meters. For the bonus game, we played a game about dogs, we had to convert the fractions into decimals and the more you get the faster you go, I know right pretty of the topic. But anyway thanks for reading and see you in the next one.

Reasoning in Geometry


Today we had a recap on angles, this angle is a revelation angle or a 360 angle. To find out what y and x is we have to cover the bottom left line then it would look like the picture below.

This angle is a straight angle or a 180 angle, to find out y we have to take away 90° from 180 then you get 90 so y=90.
This is the same angle as the one on top, since we already know that y is 90 so we do 180°-90° then that equals 90° so x=90°

Math, WALT: Comparing Fractions

Today we are learning how to compare fractions for example look at the picture bellow

 Comparing Fractions

comparing fractions is when you use <,> or =. < means the fraction on the left is the greatest and > is the opposite and = means the fractions are the same.

Exercise 1








Exercise 2


Math, WALT: Multiply the following numbers by 10, 100 and 1000 (without using calculator)

 When multiplying decimals (numbers which have a decimal point in them) by 10, 100, 1000 we just shift the decimal point to the right


By 10, one place to the right 5.78 x 10 = 57.8

By 100, two places to the right 34.589 x 100 = 3458.9

By 1000, three places to the right 2.36976 x 1000 = 2369.76

We use BEDMAS to solve problems with 
multiple operations. 
B Brackets 
E Exponents 
M Division I Multiplication 
Addition I Subtraction




Section A-Calculate

1)   7 + 8 x 3 = 31


2)   20 - 4 x 2 =12


(3)  17 + 3 x 6 =35



4)   7 x 3 - 2 x 3 =15


5)   3 x 6 + 8 x 2 = 34

6)   7 x 3 – 2 + 4 = 23

7)   6 x 6 + 8 x 2 = 52


8)   9 + 3 x 2 - 4 = 11

9)   14 ÷ 2 – 10 ÷ 5 = 5

Today we learnt how to do questions using bedmas or pedmas.
