STEM Launch with the Minister of Education

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.

2nd class Investigates :The Science of Sound

Experiment 1: Count the Taps!

What were we investigating?

Do sound waves travel better through a gas or a solid?

What did we do?

We learned that the air that we talk through is a gas and it can be interfered with by things like the wind.

We tested to see if we could count a tapping noise more clearly if we listened with our ear on the desk.

What did we learn?

In a solid you can hear the sound waves clearly. We weren’t sure however, if they were clearer.

Experiment  2: Making Rice Jump

What were we investigating?

Can we see sound waves at work?

What did we do?

We placed some cling film over a bowl and then placed some rice on top of the cling film. We then banged a drum close to the rice to see if the sound waves could make the rice jump.

What did we learn?

Even from a distance away the sound waves travelled from the drum hit the cling film and made the rice jump. Even though they are invisible we can see the force moving the rice.

Experiment  3: String Phones

What were we investigating?

Can we make a “phone” to send a message from our class across the front of the school to Mr Scott’s room (Room 5)?

What did we do?

Step 1: We designed and made our own string phone’s and tested them to see if they worked.

One group tried putting two strings in their phone.(It didn’t seem  to work any better)

Step 2: We measured to see how far apart our phones stretched and we tested to see if the sound got weaker on the longest phones.

Step 3: We then made another test string phone 4 metres long and we tested to see if it still worked.

Step 4: We measured the distance from our classroom to Mr Scott’s using a trundle wheel. It was  21 metres and 61 centimetres window to window.

Step 5: We made our new extra-long string phone. We sent a group down to Room 5  to listen for the message and left  two children in our class to call  it out.  Nobody but the callers knew the message (It was: “ Ireland are going to win!”).

 

Step 6: We  decided to do a final test to see if we could “listen in” on the line between the two classrooms.

What did we learn?

We learned lots but the most important bits are:

  • The string has to be pulled tight for the phone to work well
  • Putting two strings on the phone might actually make it harder to hear a message.
  • The quality of the phone does not diminish between 1 and 4 metres.
  • On a very long string- phone the message isn’t as clear as on a short one but we were still able to  work  out the message that was transmitted.
  • By attaching another string to the main line we can “listen in”.

 

Science Week in Senior Infants!

We have loved doing lots of experiments this week for science week! We have been busy exploring different materials that float and sink. We predicted, tested and recorded our results. We especially loved doing the “Dancing Raisins” experiment and designing our own boats! We tested our boats by counting how many “passengers” it could hold before sinking.

Exercise and your Heart

In fourth class we have been busy testing our heart rates. Before exercise we tested children’s heart rates using the heart rate monitor. After the exercise we tested them again to see if there was any change in their heart rates. The heart rate monitor told us how many times their heart beat per minute (bpm). Here are some of the results we collected.

Results

Kalya                Before exercise 96bpm

                          After exercise 120bpm

Oliver                Before exercise 90bpm

                           After exercise 130bpm

Declan              Before exercise 78bpm

                          After exercise 135bpm

Oscar               Before exercise 150bpm

                          After exercise 200bpm

 Conclusion

We found out that your heart rate changes after exercise. It beats faster. Oscar had a high heart rate before exercise and we know this was because he was nervous and excited about using the heart rate monitor. He was also doing a lot of talking at the beginning!!

For the next few weeks we are hoping to use the heart rate monitor before and after P.E every week.

Science Week

Yesterday we had our first Science exhibition of the year. We had great fun showing all of our visitors our project on ‘Electricity’. Our question was ‘How do we get the light at the top of a lighthouse to shine?’. We figured we needed to make a closed circuit. We loved explaining about the various circuits we made, such as series and parallel.  We already can’t wait for the next Exhibition! Take a look at some of the pictures below.

3rd Class Room 10

Magnets – ASD Class

For this year’s Science Exhibition we combined sensory play, maths and science into one fun activity! We each took turns to find hidden objects in a tray filled with pasta and tested them to see if they were magnetic or non-magnetic. We sorted the objects into two sets and recorded our results on a data chart. We all had great fun using the horseshoe magnet and investigating what is attracted to it. Lorchán did a fantastic job presenting our work to parents in the hall.
