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.

This morning in 5th class room 7, we started maths hour. During this hour, we had to move around to different stations in groups. We had four stations; maths diction, problem solving cards, tangrams and IZAK 9. In the maths diction game, one person picked a card which had something to do with maths language. For example, an angle or a decimal point. Your teammate had to guess the answer from your drawing, definition or hint. On another table, we were given maths problem cards which displayed pictures of the same object. We had to spot the odd one out. On the tangram’s table, we had sheets of paper with outlines of items and we had to construct the different items using all 7 tangrams. IZAK 9 was the last table and we had to complete 2 tasks based on algebra.
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 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.
