Grow It Yourself (GIY)

We received our growing packs yesterday from Innocent Smoothies. The packs contained seeds, cups, compost and growing instructions.

There were 3 seed packs, Cress, Spinach and Peas.

We had great fun today planting our seeds! We each got a pot and we planted Cress, Spinach and Peas. The Cress was the most popular, then the Peas and finally Spinach.

We also got a copy of our growth chart and we look forward to measuring the seedlings when they germinate.

The Blackbirds nest

Nest

We learnt about a nest in school yesterday. There was a cracked egg inside.We learned about the life cycle of birds.Ms Ferguson showed us pictures of birds and when they grow up. There was blackstuff in the nest that looked like shells. We reckoned it was a blackbird by the eggs. The bird was very clever by using mud to stick it together and used leaves as bedcover.Their eggs are a light aqua colour.The sticks were tucked in very well . It shows that blackbirds are very clever . But  sometimes they are very cruel to their speicies .The male bird doesn’t help build the nest at all ,the female does all the work.Sometimes the dad kicks the baby birds out of their nest . It can also take ages to crack open the egg. We watched a video where a egg hatched at x30 the speed. They also have a tooth to crack open the egg.It was great fun !!!! and NEVER go near or disturb a nest!!!!!!!Thank you BY Lucy Andrews

Designing Bridges

Using books and A4 paper the class had to design a bridge that toy cars could drive over. If you used a single piece of flat paper the bridge collapsed under the weight of the car. You were not allowed to use anything other than paper to strengthen the bridge.

Working in pairs the children came up with lots of successful designs. These included:

  1. Using several pieces of flat paper.
  2. Folding a sheet of paper 2 or 3 times.
  3. Folding up the sides of the paper.
  4. Making an arch (using two pieces of paper).

Our class is full of scientists and engineers.

Hayley’s snake come to visit!

On Friday, Hayley’s Dad came in to visit our class and he brought their two pet snakes! It was brilliant, Hayley’s Dad told us lots of facts about the two snakes. Destiny is a Dumeril Boa and Cody is a corn snake. All week we have been learning about unusual pets and these were certainly unusual!

Thanks a lot to Hayley’s Dad for bringing them in, we had a brilliant afternoon…although Ms Ferguson looked very scared!snake 1 snake 2 snake 3 snake 4 snake 5 snake 6 snake 7

Science Week – Rainbow Milk

We put some milk into a wide bowl.  We added some drops of food colouring, red, blue, green and yellow. We then dropped a blob of washing up liquid into the middle of the milk.

You can see in the picture what happened.  The colours swirl and mix in the milk. This is because the washing up liquid breaks up the fats in the milk causing the colours to swirl.

This is why washing up liquid is so good and cleaning dirty dishes!

Science Week – Kissing Balloons!

We tied two balloons onto a stick. Using a hair-dryer we blew air between the balloons.

We all predicted that the balloons would separate.  However when we tried the experiment, the balloons actually came together!

This is because fast moving air exerts lower pressure than the slower moving air around the balloons, so they are forced together.

We were very surprised by this experiment.

Science Week Experiments: Bouncy Egg and Dancing Raisins

We conducted two science experiments today.

The first is called Bouncy Egg. We put an egg into a cup full of vinegar. Vinegar is an acid, and although an egg shell is hard it contains lots and lots of tiny holes. Vinegar is an acid. The vinegar will dissolve the egg shell so the the egg becomes ‘bouncy’ and rubbery to the touch.

DSC_0622You can see all the bubbles on the surface of the egg in the picture.

 

 

 

 

The second experiment was called Dancing Raisins.  We placed a handful of raisins into a glass of fizzy water. They fall to the bottom. Fizzy water contains a gas (carbon dioxide). The gas bubbles attach to the raisins, making them more buoyant so they rise to the top of the glass. As they hit the surface of the water the bubbles pop and the raisins fall back to the bottom of the glass again.downloadimages

Science Week

This week is Science Week.  It is the 20th anniversary of Science Week in Ireland. You can find more information on their website here.

Here are some interesting and funny science facts. (From a website called Science For Kids)

  • Rabbits and parrots can see behind themselves without even moving their heads!
  • Butterflies taste food by standing on top of it! Their taste receptors are in their feet unlike humans who have most on their tongue.
  • Most of the dust in your home is actually dead skin! Yuck!
  • Although the Stegosaurus dinosaur was over 9 metres long, its brain was only the size of a walnut.
  • Humans get a little taller in space because there is no gravity pulling down on them.
  • Because of the unusual shape of their legs, kangaroos and emus struggle to walk backwards.
  • A hippopotamus may seem huge but it can still run faster than a man.
  • Even if an analog clock is broken, at least it shows the correct time twice a day.
  • Sneezing with your eyes open is impossible.
  • The trickiest tongue twister in the English language is apparently “Sixth sick sheik’s sixth sheep’s sick”. Give it a try and see for yourself.

 

Can you balance?

The challenge

Stand with your back and heels against a wall or door and your legs straight. Drop a coin on the floor in front of you. Can you pick it up without falling over?

The reward

You get to keep the euro coin.

What we learned

It’s not possible.

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. But with the door there, this is impossible, so you tip over and Mr. Gorman gets to keep the money.
