Yesterday morning we had a lovely walk in our local park. We counted our strides for a full lap and found out there were about 700 strides altogether. Some clever minds then remembered that on average a young persons stride is about half a metre in length. They then calculated that it must be about 350 m per lap ! Smart minds and healthy bodies in 2nd class!
We had lots of fun today baking cupcakes. Each of us had a special job to do. Michael read aloud the instructions. Lorchán organised the baking equipment and ingredients throughout. Siluan carefully cracked the eggs and measured the flour using a weighing scales. Seán and Thomas mixed all of the ingredients together. Lastly, Ciarán spooned the mixture into the individual cupcake cases. Together we put the cupcakes in the oven and eagerly monitored the time on the classroom countdown timer. Once cooled down, we ate one delicious cupcake each and brought another home. We were happy boys and are excited to bake again soon.
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.
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.
We were honoured to have the Minister of Education Richard Bruton launch the policy and implementation plan for STEM in education in Ireland. Minister Bruton had the chance to talk to come of the students about what they have been learning in science and maths. Here are a few pictures from the day.
We investigated the respiratory system for the science exhibition.
First of all we learned how we breathe and the parts involved in the respiratory system.
We then carried out two experiments: How to Make a Model Set of Lungs and How to Measure Your Lung Capacity.
How To Make a Model Set of Lungs
A 2 litre bottle, 2 balloons, blue tack, a rubber glove, sellotape.
Step 1: First, cut a 2 litre bottle in half.
Step 2: Next, place a straw into a balloon and use sellotape to stick it on. Ensure that there is no air getting through. This will represent our trachea and our lung.
Step 3: Repeat step 2 as we have 2 lungs.
Step 4: Then, place the two lungs through the top of the bottle and secure using blue tack. Again, make sure that there is no air getting through.
Step 5: After that, place a rubber glove on the bottom part of the bottle.
Step 6: Finally, pull down on the rubber glove to show the air coming into the lungs and going out of the lungs.
What We Have Learned:
- The diaphragm moves down when we breathe in to make room for air in the lungs.
- The diaphragm moves up when we breathe out pushing out the air.
- The diaphragm is an important muscle in our breathing system.
How to Measure Your Lung Capacity
Permanent marker, 5 litre bottle, basin, plastic tubing
Step 1: First, using a permanent marker, mark off a 5 litre bottle into 250 millimeter intervals.
Step 2: Next, fill the bottle up with water.
Step 3: Then, place a piece of tubing into the bottle.
Step 4: Ask your friend for some help in placing the bottle into a half filled basin of water. Ensure it is placed in the sink in case there is an over spillage of water.
Step 5: After that, place the tubing in your mouth. Taking an ordinary breath, blow out as much water as you can.
Step 6: Record, in millimeters, how much water you have blown out of the bottle.
Step 7: Then, fill up the bottle again. This time take a deep breath and blow into the bottle.
Step 8: Record, in millimeters, how much water you have blown out of the bottle.
Step 9: Do 15 minutes exercise a day for two and a half weeks.
Step 10: Finally, repeat Steps 2-8 after two and a half weeks.
What We Have Learned:
- Two people from our class measured their lung capacity before and after 15 minutes of exercise over two and a half weeks
- The results showed that their lung capacity had increased after two and a half weeks
We also carried out our own research about the respiratory system. This included information about; Smoking and the Lungs, How the Respiratory Works with Other Systems in the Body and Asthma.
