Sound in 2nd Class

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.

Science Exhibition ~ ASD Class

STEM Activity: To programme a Bee-bot to move in the shape of a circle

Skills Development

Working Scientifically

  • Predicting
  • Observing
  • Investigating and experimenting
  • Recording and communicating

Equipment:

  • Bee-bots
  • Markers
  • Rubber bands
  • Paper

What we did:

Lesson 1

  • We watched a fun video about the circle with a catchy song.
  • Lorchán wrote the word ‘circle’ on the whiteboard.
  • Each of us had a turn at drawing a circle on the whiteboard.
  • We did a hunt around the classroom to find circular objects. We really enjoyed this.
  • We sat at the group work table and read through our Bee-bot social story.
  • Thomas ordered sandpaper numerals from 1-4 on the table and we looked at the 4 pieces of equipment which we needed for the experiment.
  • We each took a turn at programming the Bee-bot to move in the shape of a circle by pressing the right arrow 4 times.
  • Ciarán cleverly pointed out that we could also press the left arrow and it would still move in the shape of a circle.

Lesson 2

  • We watched the video about the circle again.
  • We recapped Lesson 1 by looking at photographs on the interactive whiteboard which were taken during the lesson.
  • We discussed how we could confirm our observations and prove that the Bee-bot can move in the shape of a circle.
  • We observed Ms. Groarke attaching the marker to the Bee-bot with an elastic band.
  • Each of us took a turn at programming the Bee-bot to move in the shape of a circle with the marker attached. We pressed the right arrow 4 times and ‘Go.’ Then we pressed the left arrow 4 times and ‘Go.’
  • Sometimes we had to press ‘Go’ more than once and adjust the marker so that it left a more visible circle on paper.
  • We labelled our work with lots of care as you can see.

Lesson 3

  • We watched the video about the circle one more time.
  • We recapped Lessons 1 and 2 using photographs.
  • We discussed if 2 or more Bee-bots could move in the shape of a circle at the same time.
  • We agreed that that they could once we press the right/left arrow the same number of times and ‘Go’ at the same time.
  • We prepared 2 Bee-bots by turning them on.
  • We pressed the right arrow 4 times on both Bee-bots.
  • We practiced pressing ‘Go’ on the 2 Bee-bots at the same time and observed them mostly moving in unison.
  • After a few trials, we did it one last time and video recorded our results.

We hope you enjoy reading about our contribution to this year’s Science Exhibition!

Science in Senior Infants.

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?! 🙂

We had such wonderful costumes today in senior infants, well done to all the boys and girls for taking part so enthusiastically and putting in so much effort! Thanks also to the parents for their help in making sure all the children came to school dressed up. I hope you all really enjoyed it! Happy Halloween😊

Book Character Costume Parade

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!
