The Globe Project – 5th Class Room 7

This year, as part of the GLOBE initiative, our class has been examining the weather in the school environment. We have been analysing clouds and measuring the amount of Particulate Matter (PM) in the air using our cloud charts and the Calitoo instrument. We have also been measuring the amount of rainfall using our rain gauge and examining the temperature and barometric pressure using a thermometer and a barometer. Every time we completed our analysis, we recorded the data onto the GLOBE website.

Some students in our class made a homemade thermometer and barometer to see if they could be used as an accurate way of reading the temperature and the barometric pressure. We compared our results to the actual readings on the thermometer and barometer in our instrument shelter.

This year, we were given special test tubes which measured the amount of nitrogen dioxide (NO2) in the school environment. Nitrogen dioxide is generated when nitrogen from the car engine mixes with oxygen in the air. We chose to place these test tubes in three locations around the school. These locations were; the school gate, the staff car park and the school garden. We made predictions about which location we felt would have the most and least amount of NO2.

Results:

School gate: 26. 85 (µg/m3)

Staff car park: 24.85 (µg/m3)

School garden: 20.92 (µg/m3)

Our predictions were correct!

NO2 concentration (µg/m3) Description
50 + Extremely bad
45 – 50 Very bad
40 to 45 Bad
35 – 40 Substandard
30 – 35 Mediocre
25 – 30 Average
20 – 25 Pretty good
15 to 20 Good
10 to 15 Very good
0-10 Excellent

From there, we decided to complete a project on acid rain as our research told us that nitrogen oxides are present in acid rain. We completed 3 experiments.

Acid Attack: This involved us placing 5 bean seeds on damp cotton wool which were on two jam jar lids. Each day, a student from our class sprinkled both lids with  water and poured lemon juice on just one of the lids (labelled acid rain). This was used to show how acid rain affects vegetation.

We also took a piece of cement and placed it in a jar of vinegar to show the affect of acid rain on buildings.

Acid Rain Indicator:  This involved us making an acid indicator from red cabbage. We tested the rainwater in our school environment. We compared our results to a jam jar with baking soda and a jam jar with vinegar. This enabled us to identify whether the rain water was acidic.

The Water Cycle: We placed a food bag with some water out on the window sill in the sunshine which demonstrated how acid rain is made and falls.

Results: 

Acid Attack: The beans on the lid labelled acid rain were more eroded than the beans which had no lemon juice on them.

Acid Rain Indicator:  The acid jar turned a pink colour and the base jar turned a light purple. The rainwater in our environment was neutral as the colour of the indicator did not change.

The Water Cycle: This demonstrated how acid rain is made and falls to the ground through the water cycle.

What a busy and fantastic day! We had our annual book character parade. Well done to all the boys and girls who put a huge effort into dressing up as their favourite book character.

Be safe and have a wonderful mid term break everyone!

European Week of Sport 2018 #TugofWar

What a fantastic week we have had here in St Clare’s! We have been busy this week taking part in different activities for European Week of Sport. To finish off the week today, 6th class took on the teachers in tug of war. The teachers definitely need to work on their strength as 6th class beat them 2-1. Congratulations 6th class!

Well done everyone for participating so well in a superb week of sport!

The Globe Project – 4th Class Room 6 and 5th Class Room 7

Today we completed cloud observations in groups. We examined the clouds in the sky and then some of us were given the opportunity to use the CALITOO. This instrument measures the amount of aerosols (particles) in the air. We hope to be uploading this data to the GLOBE website in the coming weeks. P1030922

GLOBE Project

Our fourth and fifth classes were getting started with some cloud observations in preparation for our GLOBE project this year. GLOBE is a project run in conjunction with the EPA, An Taisce and ESERO, the European Space Agency.

The project monitors aerosols and air quality around the world. Our young scientists were practicing their skills at cloud observation and classification. They will be recording their results  online and sharing them with schools and scientists around the world.  Here you can see them hard at work.
