Zookeeper Visit

A Visitor From Dublin Zoo!!

  

Jim from Dublin Zoo came to visit our school and talk to all the boys and girls. He brought lots of cool things to show us!!

This is an elephants tooth. Did you know elephants only have 2 teeth??

This is an ostrich egg. The ostrich is the biggest bird in the world. Did you know ostriches can't fly?? But they can run really fast!

This is a leopard skin. Jim told us that leopards are really clever. Did you know they can climb trees??

Jim also showed us an elephants foot and tusks. Did you know that elephants walk very quietly even though they are so big and heavy??

This is a turtle. They live in the sea. They come out of the sea up on to the beach to lay their eggs. They bury the eggs in the sand and then go back in to the ocean. Did you know that turtles never meet their mammy or daddy?? We think baby turtles must be very brave!

This is a tiger skin and a mountain lion skin. They were much softer than we expected. Did you know the smallest tiger in the world is the Sumatran Tiger??

Senior Infants Room 4 at the Science Fair!

THIS WEEK IS SCIENCE WEEK IN SCOIL MHUIRE!

We visited the Science Fair today. We learned about magnets, balloon rockets, light houses, string telephones, gravity, string telephones, building houses from cards and much much more. Here are some pictures!

Strange Sounds in Room 4

During Science Week Ms. Burke came in and did an experiment with us. 

We explored Sound!

We found out that sound is energy.

We did an experiment to see sound.

We needed:

A drum (we used boxes and tins!)

Clingfilm

A bowl

Rubber band

Rice.

How we did it:

1. First we stretched the cling film over the bowl and secured it with a rubber band.

2.  We sprinkled some rice on top of the cling film.

3.  Next we banged our drum beside the bowl with the rice on top.

   

 

 

Results:

We could see the sound. It moved the rice and made it dance. The closer the drum was the more the rice danced.

We also  felt sound. You can feel it too! Just put your fingers on the outside of your throat when you are talking. Can you feel it?

Next we tried another way to feel sound.

We used: a balloon.

How we did it:

We held the balloon against our ear and our partner pressed their lips against the balloon and spoke.

Results:

We could feel the vibrations through the balloon when they spoke.

Next:We decided to see how many balloons we could hear through.

 Rian could hear through 7 balloons.

 

Static Electricity in Room 4

Static Electricity

During Science Week Ms. Shields did an experiment with us all about static electricity.

Static electricity occurs when an electric charge builds up on an object.

This can happen by rubbing certain things together. 

We rubbed a balloon against our jumpers and put it close to our hair. The static electricity made our hair stand up!!

The static electricity made the balloon stick to the wall!!

 

 We did an experiment to see which material produced the most static electricity!

We needed:

Different materials: wool, nylon, cotton, tissue, silk.

Balloon

Rice Krispies

How we did it

We rubbed each piece of material with a balloon.

We made the rest fair by rubbing each material the same number of times with the same balloon.

We counted how many rice krispies the balloon picked up after being rubbed on each material.

 

 

Results:

Wool and Nylon produced the best static.
