Seed Planting

Junior Classes have been learning all about lifecycles.

They learned all about the lifecycle of plants and flowers. 

 

Here is first Class growing their own daffodils. Plants need soil, water, sunlight and love to grow! 

                                       

Infants planted their own cress seeds and were amazed at how they grew so fast!

   

 

Recreate Visits Balrothery March 2015

Recreate centre visited infant classes and made beautiful art out of recyclable materials.

We displayed the artwork in our school hall to remind us how important it is to look after our environment and to reduce, reuse and recycle! 

Paper Plane Experiment

                                     Written and Typed by Heather Delaney 6th Class.

Engineer's week took place from the 2nd to the 6th of February. In our class we decided to explore the art of designing paper airplanes through paper construction. We worked in small groups to design a basic paper airplane. As a class we went outside to fly the paper planes and record the distance travelled. The furthest distance the planes travelled was approximately 10 meters. We used trundle wheels and meter sticks to measure the distance of the planes. That night for homework Ms. Andrews assigned us the task of designing a good paper airplane with the aim of travelling the furthest distance. We used the internet to research the best paper airplane designs.  The next day our class went outside with our newly designed paper airplanes. We conducted three tests to see if we were successful with our improved designs. In comparison to our basic design, the furthest the best plane flew was 23meters, a big difference!

If given a piece of paper and asked to throw it as far as it can possibly go. What shape would you pick? Not many would throw the paper as a sheet, and some people would scrunch it up as a ball for it to fly. If done right, a paper plane will fly further than any other shapes. This is because it is aerodynamically the best shape to use. This means that the air affects the paper less than if it were a different shape. In other words if you were outside on a really windy day, the larger you make yourself, the more likely you’ll blow away. A bus or a truck will be more likely to be affected by the wind than a normal car. The shape of a plane is sleek so therefore there will be less resistance due to air and it will travel further. These principals are widespread in the engineering world, with aeronautical engineers specializing in this subject. Without these types of engineers, there wouldn’t be any helicopters or aeroplanes, and many skyscrapers would have collapsed due to wind.

PAPER HELICOPTERS by Mallory Butterly 3rd Class

 

What we need for the experiment:

Template, paper clips, scissors and paper helicopters

This is what you do!

  1. Cut out template and attach a paper clip.
  2. Fold back the wings.
  3. Hold two helicopters (big and small) at the same height and let them drop
  4. See which one hit the ground first.

Results:

The small helicopter hit the ground first because it has a  small area so there is less air resistance. The big helicopter hit the ground last because it has larger surface area for air resistance.

What we did next:We put paper clips on to the heavier helicopter to see if it made a difference. We estimated how many paper clips it would take to make the bigger helicopter fall at the same speed as the small helicopter. I guessed 5 and it took 7 which is a difference of 2 paper clips.

Fact

The shape of the blades and the weight are really important as they make it spin when dropped from a height.

                                               

Engineer's Week 2015

Engineer's week 2015 was a great success. We had 3 local engineer's visit our school and talk to us all about different types of engineering. Some classes did engineer's week experiments. Our class learned about aeronautical engineering. We designed and flew paper planes and measured the distances they flew. We then learned how to make a graph on our class computer to show the results. I wrote a report on our paper plane experiment. Ms. Taylor's class did the same. Junior Infants examined an egg that had been left in vinegar for a few days. Ms. Farrell's class explored chemical engineering with a mentos and diet coke experiment!
