What unit of measurement do you think has been used to measure the rainfall?

Use this data to make a line graph. Your line graph must have:

– A chart title

– A y axis

– An x axis

– A y axis title

– An x axis title

You will need to analyse the graph once it has been completed and record what you have learnt from the graph in a summary. You will then be able to construct the graph on a laptop.

1. Reece says:

– How has rainfall differed between the two years?
It might just be the 2 years because every year has different amount of rainfall.

– Which year has had the most rainfall?
2011 had the most rainfall because it says at the end of the year and 1968 had 551.2 and 2011 had 862.8 total rainfall.

– What months had the highest rainfall?
February had the highest with a total of 168.4 rainfall in 2011 and 1968 in total, then April with a total of 164.1 rainfall in the 2 years and then in third was May with 161.6 total rainfall in the 2 years.

– If you were to pick one month for the year to have the most rainfall, what month would it be? Why?
July because July is dead in the middle of winter and in winter is meant to have the most rainfall every year.

– Why is there a difference between the two years?
Every year has different amount of rainfall.

In 1968 the rainfall stayed at more consistent rate then 2011. In 2011 there was a lot of rainfall at the start and end of the year and only a little during the middle of the year, Where as in 1968 it hardly rained apart from in March, April and May.
The year 2011 had more rainfall according to the data. In 2011 there was 862.8 inches of rain and in 1968 there was only 551.2 inches of rain!
February had the highest rainfall, a total of 168.4 inches of rain in both the two years.
I think that if I were to choose the month with the highest chance of the most rainfall in the coming years I would choose February because over the years global warming has rapidly increased the rate of rainfall during the month of February at random!

3. Chloe Holmes says:

How has rainfall differed between the two years?
Rainfall has differed between the year because of the climate change.
Which year has had the most rainfall?
I believe that April is the month with the most rainfall.
What months had the highest rainfall?
I believe that April is the month with the most rainfall.
If you were to pick one month for the year to have the most rainfall, what month would it be? Why?
I would pick February because it has most rainfall put together in both years.
Why is there a difference between the two years?
There is a differents between the two years because of climate change.

Summery

1. The rainfall was different between 1968 and 2011 because in 1968 the water was really low and in 2011 the water level was really high in some months.

2. If I had to pick a month with the most rainfall I would pick April because it has an average amount of rain fall in each year.

3. The year with the most rainfall is 2011 because in 1968 in was global warming and in 2011 it wasn’t global warming.

4. April has the most rain fall out of all of the twelve months.

5. The reason because of the difference between 1968 and 2011 is that in 1968 it was global warming and in 2011 it wasn’t global warming.

SUMMARY
-How has rainfall differed between the two years?
In the start of the year of 1968 the rainfall there was not much but in the middle of the year the rain is going up but in July it went down and in October and December went up.
In the start of the year on 2011 went up high but after it dropped down and after went up and it kept going like that until September started to go up and up but in December went down.
-Which year has had the most rainfall?
2011
-Which month has had the most rainfall?
APR
-The most month of the rainfall is Apr because if you look in 1968 the rainfall is 67.2 and in 2011 96.9.
I think that the different from the year is climate change.

-Why is there a difference between the two years?
There is a difference that is, they have a different amount in between each number because there are different numbers!

Summary
The reason why we have had more rainfall in 2011 than 1968 is all to do with evaporation. You see, it depends on the warmth of day, the hotter it is the quicker water evaporates, that means that the clouds get the water quicker and fill up quicker and when it is full it burst releasing all the water it had collected thus restarting the process. If I chose a month to have the most rainfall it would probably be July, because there rainfall between 1968 and 2011 is very similar.
