Caring for our environment - A world without oil and which is better? Public vs Private transport

posted Jun 23, 2021, 3:03 PM by Owen Breslin   [ updated Jun 23, 2021, 3:47 PM ]

Mr Breslins class were busy in early June learning about issues concerning our environment. One of our Big Cat readers, the excellent "What if we run out of oil?" by Nick Hunter proved to be truly inspirational to us as it prompted a discussion about energy consumption and about where oil comes from, what it is used for and what can be used instead of oil.

Using this book and chapter 10 of our geography book the boys and girls also learned about where oil comes from and the environmental damage that can be caused when it is spilled and also when it is burned causing emissions.
We also learned about alternatives to oil. These include
  • using renewable energy such as solar, geothermal, wind
  • using energy efficient appliances
  • using energy conserving materials such as insulation
A class survey was conducted to determine use of these at home. Some of the results found were as follows:
  • There was very little electric cars although some parents had hybrid cars
  • some people used heat pumps or solar power at home
  • no-one generated their own electricity
  • Most of the class had well insulated homes
  • Almost all of the class households used energy efficient appliances or bulbs




Keeping on this theme we then moved to a discussion about the merits of using public transport vs private transport. 
After a fascinating discussion the boys and girls wrote a piece of persuasive writing advocating for either private or public transport.

Sen Infants Welcome new Chicks

posted Jun 21, 2021, 4:47 PM by Owen Breslin

Ms Murrays class welcomed some new additions to the class recently. They had been keeping an eye on some eggs for the last 2 weeks as they learned about the lifecycle of a chick. . The eggs which were kept in an incubator hatched last week much to the delight of everyone in the school. Well done to Ms Murray and her students who got to witness the miracle of new life.

  
  

  

   





Materials - Testing Materials to determine which one would make a good air filter

We have all become accustomed to using masks in our everyday lives. However people have used dust masks far longer than this. Air filters that catch dust and other small particles are used in technology all around us. Pupils in 6th class explored the use of air filters recently. 
We listed places that air filters could possibly be used. Some of the possible applications suggested included:
  • dust masks to be worn while working in dusty environments
  • special safety masks to be used while spraying
  • air filters for cars
  • air filters for factories (a relative of one of our children works in a clean room)
  • air filter for the class projector
After discussing these for a while we decided that not all filters would be the same. For example a dust mask may not provide enough protection while spraying dangerous chemicals. We decided to test materials to determine which one would make a good dust mask.
Pupils chose to test J Cloths, microfibre cloth, scrubber, a sponge cloth, paper towel. 

After examining each sample of material, each group performed the following test. Cover the nozzle of a vacuum cleaner with a sample of each test material and try and vacuum some flour. (This represented the dust.)

After an initial test, it was discovered that the vacuum was too powerful and we could not tell how much flour was absorbed by the test material and how much was just let through. 
We covered the nozzle of the vacuum with dark material and we covered this with a sample of each material in turn. This worked much better as we could easily tell how much flour was blocked by the test material and how much went through and was visible on the dark material inside.

The following are the findings of one group.

This week, we carried out some fun experiments for science week. 


First, we made a gas by creating a chemical reaction between vinegar and bread soda. To prove that a gas was produced, we attached a balloon to the top of the bottle. The balloon inflated so it was clear that a gas was produced. 


Next we investigated how exercise increased our heart rate. We checked our pulse when we were sitting down to get our resting heart rate in beats per minute (bpm). Then we did some strenuous exercise for 10-15 minutes. When we checked our heart rates again, they had increased a lot. We learned that this happens because our muscles need more oxygen when we are exercising and blood carries this oxygen to the muscles. Therefore, the heart needs to beat faster and work harder. 



Finally, we made ‘lava lamps’ using oil, water, food colouring and fizzing tablets. We learned that oil is less dense than water because it floated on top of the water. We also learned that the gas produced by the fizzing tablet is less dense than both oil and water because it rose to the top, carrying a colourful droplet of water with it. When the gas escaped at the top of the bottle, the colourful droplet sank back down to the bottom of the bottle because water is the least dense of them all.

Ms Screeney’s class carried out great investigating work for Science week. They investigated which material made the best insulator. The children had great fun making raisins dance and they also investigated the effect of density and gases through making their own lava lamps.

Science Week - Ms Phelans 2nd / 3rd class - floating

posted Nov 18, 2020, 12:40 PM by Owen Breslin

This week we were learning all about density. We learned that objects sink in water when they are denser than the water. We decided to test this out by using an egg, salt and water. The egg sank in the water. So we added salt to the water. By adding salt, the water became denser. When the water was denser than the egg, the egg floated.

In First class we discussed what dampness is, the cause of dampness and how it affects homes in Ireland. We also discussed what prevents dampness (damp course) in homes. We decided to investigate what materials will make the best damp course.

We used sugar cubes stacked as blocks, water and food colouring to demonstrate how moisture absorbs up through the blocks (wall).

We put different materials such as kitchen roll, plastic and parchment paper between each sugar cube to see which material would prevent the water from rising through the sugar cube.

Our Results showed that plastic and parchment paper were the best non- absorbent materials (damp course), the kitchen roll absorbed all the water and did not stop the water rising through the sugar cubes.
