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?! 🙂

Incredible Edibles – Senior Infants

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!

Design a Bridge Challenge

Task: Design a bridge

Method:

Using blocks, paper, books and crayons to test we designed bridges to see which ones were stronger and could hold the most amount of crayons. We manipulated our structures to increase their strength by folding the paper used, using double layers of paper, creating arches and structures for extra support.

Conclusion:

The material from which a structure is made is important but you can strengthen a material by changing is shape. Bridge designers often use different shapes for example: arches and triangles. The curve of the arch spreads the load on the bridge and makes it stronger.

 

Spring Hunt- Senior Infants room 2!

 

Today we went on a Spring Hunt around our school grounds. We worked in pairs and used a checklist to help us to spot as many signs of Spring as we could, it was so much fun!

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.
