Testing our sences!

We explored the power of our senses during this experiment in Science. We held a piece of cotton wool, covered in vanilla essence up to our nose, while eating a piece of apple. The result was that the strong smell of vanilla essence over powered our sense of taste and the apple tasted of vanilla!!

We also identified the different parts of the tongue and got to taste things that were sweet, salty, sour and bitter. We tasted Tuc crackers (salty), fizzy sweets (sour) and lemon and lime (bitter).

Can you balance?

In order to balance when you are standing your centre of gravity should be over your feet. When you are standing and bend forwards your centre of gravity starts to move forward too. Normally, you’d compensate by sticking your bum out behind you.

In this experiment you stand with your back and heels against a wall/door. Drop a coin on the floor in front of you and try to pick it up without falling over.

With the wall/door there, this is impossible, so you tip over.



Skype Call with @Sharks4Kids

We connected today via Skype with an organisation called Sharks4kids. They gave us a lesson all about sharks.  We learned lots about and saw some great pictures. We learned how they monitor and tag sharks and how they are working to protect sharks.

There are sharks in every ocean in the world, even around the Irish coast.

Every year sharks kill about 5 people, but people kill millions of sharks. You can learn more at their website http://sharks4kids.com/

They are based in Bimini (a tiny Island) near Bermuda, where sharks are protected.


Travel Action Day & Other News

Today is Travel Action Day and everyone in St Molaga’s had the opportunity to create and present a display in the school hall for other pupils, parents and visitors from the Gaelscoil. On display, our class had our Viking Ships, our mosaic transport display and acrostic poems. Check out a picture of our display and our presenters below.

We did a science experiment for National Tree Week to show how water rises from the roots of the tree right up to the leaves at the top! To do this we used celery stalks, a container of water and some red food colouring. We added a few drops of red food colouring to the water container and placed the celery stalks in the coloured water overnight. when we examined the celery the next morning, we found that the leaves at the top of the stalks had turned red in places. Also, when we cut through the stalk, we could see that there was red in the veins of the stalk.

Why does this happen I hear you ask – Well, this happens because water in the leaves evaporates in to the surrounding air. When this happens more water is drawn up form the roots, through the stem, to replace the water that has been lost through evaporation. The water travels up in veins. Water droplets can stick together and the veins are very narrow,so the water forms a column that doesn’t break and can be pulled right up to the top.

Finally, we have several budding authors in the class who were tasked with writing their very own story books! See some of the children below with their books.

String Telephones

We made string telephones this week. We got plastic cups and put a hole in the end to put the string through. It was very hard to put the string through the hole. We tied the string around a paper clip and put the paper clip on the inside of the cup – this is so the string wouldn’t come out of the hole.
Next we talked through the telephones. The sound traveled from one cup to the other along the string. We learned it only worked if the string was pulled tight.
We got to go outside to test our string telephones. When we got used to using one cup phone each, we started to cross over with other people so we could try to hear the others. It worked if up to four telephones were crossed but when lots of people crossed wires, we couldn’t hear as well. This is because the sound was split up between all the wires.
