Lighthouses

We glued the paper onto pringles tubes and painted them to look like lighthouse.

We made electric circuits using a battery, wires, bulb and bulb-holder. We arranged the circuit so that the bulb was at the top of the
tube and the battery at the bottom.  We put plastic glasses over the bulb.

Biodiversity with Dale!

Today we welcomed an Australian  guest speaker called Dale, into our classroom to speak to us about bees, birds, bats, beetles and bugs. We even got to look at some beetles from inside a special container.  Some of us were brave enough to hold an Australian stick insect.

We explored the relationship between various creatures  who live in our environment and learned that there is a purpose for every creature in the food chain.

This “biodiversity” is essential in keeping the environment healthy and fit for human life.

Here are some pictures of Dale’s visit!

Bio-Diversity Workshop with Dale

We had a visitor called Dale this morning and he told us all about bugs, beetles, butterflies, bats, bees and birds.  He had pictures of animals from different countries, like snakes, wallabies, wombats and echidnas (which are like hedgehogs and have babies called puggles.)

He read us a story about Robby Robin. We got to hold a stick insect on our hands. He passed around bug viewers where we got to see a tarantula, a beetle, a cockroach, a spider and a larva.

He played a song called “Bats, Bats, Bats.” Dale is from Australia and when he was in high school his teachers had to go around their football pitches to remove poisonous snakes before they could play the match! He had a special animal caller that looked like a bird’s feather on a long string and when he swung it around really fast, it made a sound like a motorbike.

He also had a bat caller, and he showed a recording of bats flying in his garden so we could hear what they sound like.

Thank you, Dale, for coming to our school!

Science Week – Bouncy Egg

On Monday we put an egg into a jar of vinegar. Today, when we took it out, the shell had been eroded away! Vinegar is an acid and the egg shell is made of calcium. The egg’s membrane remained and this made the egg feel rubbery! We were able to bounce the egg on the table!                                                                                DSC_0340 DSC_0341

Testing our senses!

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.
