BTN Air Safety

The Behind The News I did for this week was about the safety of air travel. Some people and kids are starting to have second thoughts about getting on a plane because of flight MH17. 297 people were killed when air flight MH17 was shot down over Ukraine. While investigators put the mystery together, they are thinking of what they can do to prevent this from happening again in the future.

All around the world air traffic controllers are doing their jobs to fly and land planes. When pilots fly their planes, they do their jobs to fly at the right speed, right height and correct route. After flight MH17 was shot down some air flight companies where choosing not to fly over Ukraine because it had become a war zone! Despite the warning some flight companies still chose to fly over the country including Malaysia Airlines. This was because of the extra costs involved in flying different routes. When flying in a plane there is a one in an 11 million chance of dying in a plane crash, it is 22 times safer than driving in a car. Was this crash a freak event that couldn’t be predicted?

Mathsmate question 24

Prediction: I predict that this will be about adding circles together

Clarify: Nothing to clarify.

Question: The question shows four lines of different colored circles, the collars are red, gray and white. There are different amounts of colors in each circle, I had to work out what each circles number was to get my total answers. The first three lines had total numbers underneath them, the first one was 22, then 21, then 16 and the last one we had to work out.

Mathematicians tool box: I used trial and error.

Answer: the answer I got for my forth line of circles was 23

BTN Australian Energy

The Behind the News I did for this week was about Australian Energy. The main material that powers Australia right now is coal. When we burn coal it creates lots of energy but it also pollutes the environment and the atmosphere. Coal powers over 80% of our energy we use today, and over half of the coal we mine is shipped overseas to other countries. That is why the government are thinking to change our energy power source for wind farms and solar panels. Here in Australia we are known for our sunny weather and nice beaches, except for in winter when it is cold, rainy and miserable. All of our sun and wind could be used to create natural energy, but today solar panels and wind farms are producing less energy than coal. If we run out of coal then we will switch to solar panels and wind farms. Solar panels and wind farms have no impact on the environment and they can last for a long time, but developing new energy can cost more than coal. If we move away from coal then electricity bills will rise. Australia’s energy future is still undecided so there is still a chance that natural energy will become our energy source.

Mathsmate Question 24

Prediction: I predict that this will be about adding curtain numbers together.

Clarify: Nothing to clarify.

Question: The question shows 4 rows of circles each with different colors, the colors are Dark red, white and grey. At the bottom of the first row there is the number 17 the next 24 the next 8 and then there is a mystery number on the last one.

Mathematicians tool box: I used trial and error.

Answer: The answer is 13, the way I worked that out was working out what numbers each circle owned, I worked out dark red was 4, white was 1 and grey was 2, so I added 1, 4 and 8 together to get 13 as my answer.

BTN Bitter Sweet

The Behind The News I did for this week was based on sugar. Sugar is in products we didn’t know had sugar in them. Low fat items seem to have more sugar in them while full fat items have much less, for example full fat mayonnaise has 2.2 g while the low fat option has 13 g of sugar in it. Some more items which have sugar in them are tomato sauce, BBQ sauce, hamburger buns and hamburger meat. Sugar can make foods taste better and also makes them last longer.

Sugar is a carbohydrate which our body needs for energy. In the 1970s people were having too much sugar causing them to become overweight, so full fat products where replaced by half fat products. These foods didn’t taste as nice so they added sugar into them to make them taste better. Too much sugar can affect people’s health and in extreme cases they need to have surgery. It also can lead to heart disease. Some people thought that sugar should be fined, banned and taxed from supermarkets which would mean people would buy less sugar products.

The people from the sugar industry responded that there was no evidence to prove it and to show that sugar is bad. Sugar is important to our diet but we need to know when enough is enough. The maximum amount of sugar kids are to have a day is two teaspoons while a can of soft drink has five times that amount, so it would have ten to fifteen teaspoons in it.

Mathemate question 24

Prediction: I predict that this will be about number patterns.

Clarify: Nothing to clarify.

Question: The question shows four groups of circles with numbers underneath them, the numbers are 22, 24, 26 and a missing number.

Mathematicians tool box: I used the 2’s number pattern to get the answer.

Answer: The answer is 28.
