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.
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.
First we conducted a survey of the butters and margarines used in Fifth class room 6.
Then we made a tally chart and bar chart displaying our findings.
Then we identified the ingredients each of these contained. We made a stacked bar chart of these ingredients.
Some margarines contained 9 /10 ingredients including preservatives, colouring, Emulsifiers, acidity regulator Findings:
We were shocked to discover that Flora and Benecol contained the exact same ingredients as stock margarine even though they were over 4 times the price.
Then we investigated which butter or margarine would go off first. Findings: –
a) Pure butter went mouldy after 10 days.
b) However, after 3 months none of the margarines have gone off.
Finally we made pure butter by shaking double cream.
Try this at home. It is so tasty!
