RDS Primary Science Fair.
We participated in The RDS Primary Science Fair for the first time ever on Thursday 9th January. It was a brilliant experience. Our project attracted loads of attention and visitors. Here we are with Mr.Séan Sherlock, TD. Minister of State at The Department of Education and Skills with responsibility for Innovation and Research. We got to visit the other Primary and Secondary stands, met loads of people and gathered up some great ideas. We began the journey to Dublin at 5;00am. arrived at 8:30am., had a full active day and were back at at school again at 8:30pm.

R576 and The River Feale.
Why is the R576 running parallel with The River Feale? Measure the length of the River Feale from source to sea as the crow flies. Compare your result with its official length. Note the flowing directions of the tributaries.
Contours and Settlements.
Schools in North Cork, West Limerick and North Kerry.Why ?
There are also interesting comparisons to be made with the Electoral Division populations.
Waypointing 6 Neighbouring Schools.
Fiinding one's bearing is very important in any situation. Here we waypoint 6 neighbouring schools. Once again the River Feale is a striking natural feature. We will base our report on the schools' locations relative to the river and the similiar and contrasting terrain. We will also note the flow of the many tributaries. We will also examine what we think is the existing land usage.
Statistics: Cork/Kerry Birth Origins of 2011.
In the dynamic page we can see Birth Origins in County Cork, in County Kerry or in both counties. The 6 parameters used are as follows:
Origin...Irish, Poland, Lithuania, UK., Rest of EU and Rest of The World.
The data is further manipulated and produced by the students in a 3-D Pie Chart format which we will upload shortly.
Statistics: Population Change in Knockaclarig 2006-2011.
This map introduces the concepts of % increase and % decrease. We have 2 known variables 2006 Population and 2011 Population. We can therefore find the unknown variable in two formats ...numeric increase/decrease and % increase/decrease. The same system works in calculating Cash Profit/Loss and % Profit/Loss.
This authentic and local source of data illustrates the realism of this far reaching mathematical concept.
Three Rivers: Three Different Directions ???
In this situation we focus on three major rivers in our locality...The Feale, The Blackwater and The Maigue.We notice the general directions in which the rivers flow. Each river flows in a different direction. Why so? We use the earlier contour map to understand this arguement and to determine which river flows the fastest.
Can you come up with other questions and arguements?

Speed, Time and Distance.
Here we delve into the quite abstract concepts of Speed,Time and Distance. Using our dataset and obscuring one of the three elements we can work out any problem in this mathematical scenario and see through investigation how formulae are arrived at. Of course we are working, in many cases here with decimal numbers and this adds a certain rigour to our problem solving.
DISTANCE = TIME X SPEED per HOUR.
TIME = DISTANCE / SPEED per HOUR.
SPEED = DISTANCE / TIME.
Base of 60 for TIME
Bases of 10,100,1000 for DISTANCE.
We also introduce and use calculators/handhelds for these complex calculations.
