Evaporating Atlantic Seawater to make Salt Crystals

Mr. Breathnach brought us some sea water from the Atlantic Ocean so that we could try to make our own sea salt.
First we measured 1 litre of sea water. Next we put the sea water in a saucepan and put it on the cooker and we boiled it. While it was boiling Karl and I had to watch it. There were a lot of bubbles at the top of the saucepan. We boiled the water to 100ºC When our teacher came in she noticed that some salt was forming around the pot and there was even a little ring of white salt on the cooker. She knew it was salt because she dabbed it and tasted it.

Can you see the sea salt that has formed on the base of the saucepan?

Next our teacher began checking the saucepan every few minutes to make sure it didn't burn and stick to the saucepan. Eventually all the water ecaporated and we were finished it looked like dried white paint.
Finally we got all of the sea salt out of the sauce pan and put it in a bowl.When we weighed the salt on a digital scales we discovered that we had 33 grammes.

We got 33 grammes of salt from 1 litre of sea water

RDS Primary Science Fair

Did you know that crystallography is the science of studying crystals and how they form? During the last few weeks pupils from Fifth class have been working as amateur crystallographers engaging in the process of scientific inquiry as the investigated, observed and recorded their experiences making crystals.

They have boiled water, cooled water, and used graduated cylinders, cups and teaspoons as they dissolved substances, evaporated the solution and learned how to recognise a saturated solution. They used sugar, salt, Epsom salts and alum to investigate the process of crystallization. The work is almost over and now they are ready to display their project at the RDS Primary Science Fair on Friday the 10th January.
Check our the links below to find out about some of the Special Acts that I hope you will get an opportunity to see when we get a break from our stand at the Science Fair

Christmas Greeting using Scratch

We used Scratch to make some some cards for our eTwinning partners. We used seven versions of Happy Christmas (French, Spanish, Greek, Finnish, Euskera, Irish and English) in the card so that all the participants in our project could read it in their own language.



Controls: Press the Spacebar for a surprise. Use the Up and the Down arrows to move the moon up and down. Use the Left and the Right arrows to move the snowman. Click on the two snowmen or the moon for a surprise. Press the O key to reset everything. Card was made by Sannad

eTwinning

In our class we are doing an eTwinning project. eTwinning is when other schools in the EU communicate with you using Twin Space on a special website for projects. First we agreed to participate in a project called Thick as Thieves. The title means that we are very,very friendly with each other. There are five school participating in our project. They are from the following places Bilbao Spain, Tanus France, Limnos Greece and a school in Helsinki Finland.

It's great fun to be able to communicate with other people in a different country. For the project our class is divided into four groups and each group is working with a different country, but we can still get to communicate with other people in the other schools. Sometimes we go to the computer room to reply to our friends in a different country. I'm working with the school in France Tanus. I've got messages from Emily, Rania and Demmie. We are even able to log in to it at home. It's really good I'm looking forward to talking to them after Christmas.

We made Christmas card to send to our eTwinning friends. The collage will give you an idea of some of the cards that we sent.
