Science Week 2019-Middle Room

We had great fun throughout the week.  The children were involved in various experiments as well as attending a show in Belmullet on Thursday.  Throughout the week the children carried out the following experiments:

 

  1. Make an Egg Float in Salt Water
Equipment:

  • An egg
  • Water
  • Salt
  • 2 plastic glasses

 

Method:

  1. Pour water into one glass
  2. Drop an egg into it.  What happens? The egg will sink.
  3. Pour water into the other glass
  4. Stir in lots of salt
  5. Gently lower the egg into this glass.  What happens this time? The egg will float
What’s happening?

Salt water is denser than ordinary tap water, therefore it is much easier for the egg to float in the salt water.

The children also investigated how static electricity on a balloon can pick up pieces of paper

Equipment:

Balloon

Small pieces of paper

Woolly jumper

 

Method:

  1. Tear the paper into small pieces
  2. Blow up a balloon
  3. Rub the balloon on a woolly jumper for a few minutes
  4. Place the balloon close to the small pieces of paper and watch carefully what happens….

What is happening?

When you bring the balloon near a little piece of paper, the negative balloon repels the electrons in the paper so part of the paper near the balloon is positive.  Since positive and negative attract, the paper moves toward the balloon.  The negatively charged balloon attracts the paper.

 

 

The children also made lava lamps.

Materials:

  • A clean plastic bottle
  • Vegetable Oil
  • Alka Seltzer tablets
  • Food Coloring

Instructions:

  1. Fill the bottle up about 1/4th (1 quarter) with water.
  2. Pour the vegetable oil in the bottle until is almost full.
  3. The oil and water will begin to separate.
  4. Add a few drops of food coloring. Watch as the color sinks through the oil.
  5. Break your fizzy tablet in half and drop part of it into the bottle. What happens…..????

How it Works:

The oil floats on top of the water because it is less dense than water. The food coloring has the same density as the water so it sinks through the oil and mixes with the water. When you add the tablet it sinks to the bottom then starts to dissolve. As it dissolves it makes gas, carbon dioxide. The in turn creates bubbles.  This will continue until the tablet is completely dissolved.  The end- product clearly shows the separation of oil and water.

Butterfly Goodbyes

We had great fun watching our little caterpillars transform into beautiful painted lady butterflies. Alas, it was time to say goodbye to Sky, Mary, Little flower, Missy and Frederick. We released them and waved goodbye, as we know they have such an important job to do now. Butterflies play a huge role in pollination, as do bees and wasps. So we need to look after them all, as best we can!
Our little friends will live for approximately 5 more weeks(max), laying their own little eggs elsewhere, for the cycle of life to start all over again.

Caterpillars – Our fuzzy friends!

It has been really interesting so far, observing the changes that have occurred in our caterpillars, in one week! They started off so tiny and look at them now. They have been feeding so well and alot of waste, called frass, is evident in the jars. They have shed their exoskeleton a few times also! Some of the caterpillars are making attempts to hang in their ‘j’ shape, which means that very soon they will have to be transferred to their butterfly habitat! Exciting! Before transferring, they will form a chrysalis and while in the butterfly habitat, the last stage of metamorphosis will occur over time , resulting in,fingers crossed, our beautiful painted lady butterfly’s emerging soon after! We will keep you posted!

Science

Yesterday Declan the scientist came to our school. He showed us some cool things: he rolled a can on the floor and it came back all the way back to him.

After we tried to guess what happened and nobody got it right.

Then he told us how he said there was a weight in the middle of the can and there was two elastic bands taped to the inside. The science behind it is when you rolled it the weight wants to stay in place and that winds the elastic bands up and when it stops the elastic bands lets out all the energy and makes it roll back words.

Then he came into our room and made a slingshot out of lollipop sticks. All of our class had a competition with 7 people v 7. The yellows went first then red and the yellows won. I was on the yellow team and the second round the reds won.

I enjoyed the day I hope Declan comes back again another day.

Yesterday we had a visitor come to our school.

His name was Declan. He is a scientist.

He comes to our school once every year to do some science and engineering with us.

The first experiment he did was the can that would that would always roll back to you.

 

 

The second one was the mirror that makes you look like you’re upside down.

My favourite experiment was the glasses that make you look purple.

After the show he came down to our classroom and made catapults with us.

 

 

That is my favourite part of him coming every year by far. I hope that he will come next year. He said before he left that he is hoping to make a phone that can turn into anything.

Yesterday we did science with Declan.

First he got a tin with a weight and elastic bands in it and anytime he rolled it it came back to him.

Then he got a can of diet coke and a container of water and he asked us ‘Will it float?’ and most people said ‘No’. Then we put it in and it floated! Then he got normal coke and asked if it would float and most people said yes and it floated! And then at last he had Pepsi and asked if it would float and most said yes and guess what, it didn’t! He asked why and lots of people had lots of ideas and then Ava said because there’s more sugar in Pepsi than Coke and it was right.

Declan from Science Ireland

The last day we had a man called Declan come to our school. Declan is a scientist. He did lots of things with us.

He usually tricked us to believing one thing when it actual something else is happening. He showed us that there is more sugar in a can of Coke than Pepsi and Coke floats and Pepsi doesn’t.

He also rolled a tin cylinder and it came back to him like a boomerang, but more slowly. The trick was he had a weight in the middle with elastic bands wrapped around it. The bands wind up when you roll the can and the can rolls bac kas the elastic bands unwind.

After that we had a game of homemade catapults. The way you make them is you need eight lollipop sticks and elastic bands. The rules are you get a Velcro ball and fling it with your catapult and try hit the target. It was really fun and can’t wait to do it next year.

Yesterday Declan the scientist came in to do science with us.

When he came all of the senior room went down to the junior room so we could do an expiriment together.

We did really fun things all together.

Then after our lunch break he came in to the senior room and we did catapults. They were really fun and I enjoyed them a lot.

The catapults were like a cross between the movie and game Angry Birds.

My favourite one was the robot one because he was really cool and it is a really smart robot. So I liked that a lot.

Declan was really good at science and was fun too.

Yesterday Declan the science guy came to our school he did some science  with us.

The first thing he did was he rolled a can on the ground and a it came back to him. He ask  us how did it come back? Some people kind of got it. After a while he told us the answer. It was how there was a weight in side of it with some rubber band tied around it.

Then he asked which would sink: a Diet Coke can, a regular can of Coke and  a PepsI. And he put the Diet Coke in to the water and it  didn’t sink. And then he put in  the Coke and that didn’t sink . Then he put in the Pepsi and that did sink because it has more sugar.

Then he stayed with the little ones for a while.

Then he came to us and played a fun game with us  you have a ball and shoot it on to  a little carped thing and it was fun.

Yesterday Declan Holmes, the science guy, came to our school.He showed us lots of stuff to do with science.

First he rolled this can and asked us what was happening.Then he showed us Coke. Diet Coke and Pepsi cans he asked us which would float and which would sink. Only the Pepsi can sank because the amount of sugar in it.

Half an hour later he came to our room and we played a extremely fun game with catapults.They were not real ones though, but we could make them ourselves at home if we wanted.

Afterward, we asked thousands of questions! He was really funny and I enjoyed the day a lot.
