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.
We have been experimenting and testing the force of water on objects by investigating things that float and sink.
To begin we collected a variety of items from around the classroom to investigate. As a class we predicted which items would sink and float in water. Next, in our groups, we took turns to test the items to see if they would sink or float. Lastly we sorted the items into two groups; sink or float and we recorded our results.
The second activity we completed was ‘Design a Boat’. Firstly we experimented with a ball of plasticine to see if it would sink or float and if changing its shape would make a difference. Then in our groups we tried to use the plasticine to design a boat that would float. If we were successful we tested our boat to see how many ‘passengers’ (dried peas) it could carry. After a few attempts some groups were successful! 🙂
The last activity we completed was an experiment called ‘Dancing Raisins’. We predicted what would happen to the raisins in water and in soda water and then observed the differences between the two types of water. We were amazed to watch the raisins begin to ‘dance’ in the soda water! Why do you think this happened?! 🙂
On Friday last 2nd class got to help out with the giant cleanup operation on the school grounds. Together we took over a patch of ground and made sure that it was both litter and weed free. We used litter pickers, shovels and brushes to complete our zone and we are really proud of our work.
This week we worked together to plant all of our seeds from Incredible Edibles! We now have such a variety of lovely fruits and vegetables growing in our garden. We sowed strawberries, potatoes, chives, lettuce, spinach and turnips. We will be busy caring for them over the coming weeks and can’t wait to watch them grow!
Today we were lucky to observe, not one, but three Giant African Land Snails! We discussed their size, their shells and what they like to eat. Afterwards, we made our way to the Outdoor Classroom to have a look at the hundreds of tadpoles in the pond. There, we discussed the lifecycle of the frog and took some time to bask in the sunshine on the benches.
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.
