This year our class entered the Intel Mini Scientist Competition and our group was lucky enough to be selected to go to the Regional Finals. Our group’s topic was hydraulics, more specifically hydraulic bridges. We chose this topic because last year two people from our
group went to the previous regional final and three other groups did hydraulic arms and we had an interest in the science behind hydraulics. We decided to investigate hydraulic bridges.
At first we found it very difficult to construct the bridge and came across quite a few problems but after a while we figured it out. In November three judges from Intel came in and judged all the classes’ projects. Our group was lucky enough to be selected to go to the Regional Final! In preparation for the Regional Final we decided to make another bridge out of balsa wood. In December our group went to Blanchardstown IT and after a long day of presenting we made it to the National Finals in Maynooth. We were delighted when we found out we were in the top 1% in Ireland. Then the awards were announced but unfortunately we didn’t we win anything but were still extremely proud of ourselves.
Sound is an energy, caused by vibrations that makes sound waves.
We completed a dancing rice experiment to see sound vibrations. We made ‘String telephones’ to hear sound waves.
We investigated which material would be the best sound insulator. We measured how far away from the sound we needed to walk before the sound disappeared when blocked by each material. We predicted that the cardboard box would be the best sound insulator and we were right!
Some materials allow sound to pass through them easily. Other materials absorb sound.
5th Class Room 7 have been extremely busy researching information about the human eye. We learned all about the human eye, it’s parts and their functions. After that, we split into groups and researched topics relating to the human eye that are of interest to us; Optical Illusions and Braille. We also completed 3 surveys on the topics of eye colour, glasses and contact lenses and what you could see in one particular optical illusion.
Our class completed a project on the Respiratory System. Four of us were chosen to attend the Intel Mini Scientist Fair in Blanchardstown IT on the 8th of December 2017 to represent St. Clare’s Primary School. We had great fun presenting our project and got to look at interesting projects from other schools as well.
Yesterday we had our first Science exhibition of the year. We had great fun showing all of our visitors our project on ‘Electricity’. Our question was ‘How do we get the light at the top of a lighthouse to shine?’. We figured we needed to make a closed circuit. We loved explaining about the various circuits we made, such as series and parallel. We already can’t wait for the next Exhibition! Take a look at some of the pictures below.
