ECO Workshop

Today, Wednesday 15th May, a lady called Natasha came into 1st Class and talked to us all about reducing our waste, reusing different things and recycling as much as we can.

She told us lots of interesting facts about where paper and plastic come from and how they are made. We were amazed to see all of the different bags, clothes and jewellery that had been made out of recycled materials like tents, tyres and sweet wrappers!

We talked a lot about reducing the amount of electricity that we use at home.

RDS Primary Science Fair 2013 – 4th Class

Over the next few days we will update you and tell you all about the project we presented at the Science Fair. We were very lucky to be picked to take part and we worked very hard.

Last week in 4th class we went to the Young Scientist Fair in the RDS to present our project on pulley systems. We left school at 7:45am on Friday 11th January and returned at 5:30pm. We had a fantastic day and learned so much.

We will tell you a little bit about our project now.

Our Project

Firstly Miss O’Donnell gave us a set of questions. We were split up into groups and had to discuss answers to the questions. You can see the questions and answers on our display.

After that we discussed it as a class, we watched a video about single fixed pulleys and single movable pulleys.

Then each group were given six blocks. We had to try to move the big red block that we were given. After that we had to stack two blocks on top of the red block and try to move it without them falling. We couldn’t do it but then a boy in our class called Trofim came up with the idea of the pulley.

Some people made homemade pulleys and then we found out if you use a thick rope on the pulley it would fall off the spool .Then there were five people that went out with a teacher and tried to find everyday objects that used pulley systems.

We watched this video about NASA. We saw that even NASA uses pulleys that can hold up to 300,000 kg and they have 3 of them .They use the pulleys for pulling the rocket up and down .The rocket weighs 200,000 kg

We hope you enjoy our project as much as we did!

Planting Seeds

Here in 1st Class Room 9, we love experimenting and learning about different things in our environment. On Friday 27th April, we planted some cress and basil seeds that one of our classmates brought into school that day. The seeds had come with smoothie cartons and so were held inside small cardboard circles. This cardboard is biodegradable- that means that it will break down, or decompose.

Broad bean seeds: 

We decided to experiment with planting some broad bean seeds to see if they will grow in the same conditions as the cress and basil seeds. We planted these in clear plastic containers so that we can see any changes that happen. We monitored our broad bean seeds and this is what we found: on Friday 27th April we planted the seeds; on Wednesday 2nd May they had started to open; on Thursday 3rd of May the roots had started to come down and now on Friday 4th of May the roots are much longer!

Cress seeds:  We put the cardboard circles (containing the cress/basil seeds) into three separate plastic white cups in between some cotton wool buds. We made sure to keep the cotton wool wet. We checked for growth each day.

This is what we saw on Wednesday 2nd May!

On Friday 4th May, our seeds had started to grow their roots.

On Tuesday 8th May, our seeds had really grown a lot! We can see that the roots have grown all along the bottom of the cups and the shoot is starting to appear too.

By Friday 11th of May, we could see the shoots and roots trying to push out.

We took this picture on Monday 14th of May. We were sop excited to see how much more our seeds have grown and developed. The roots of both seeds are spread around the bottom of the cups and the shoots are big and strong.

As you can see, the shoots of both of the seeds have burst through the surface completely now. They are very tall and strong. The roots are spreading out even further and are pushing through the cotton wool also.

Today is Monday, 21st of May. Our plants have grown a lot over the weekend, they have tall shoots and bright green leaves now. We think they look great!

1st Class Science Workshop

On Wednesday March 14th, a scientist came in to work with us. He made ice-cream with Room 10 and he helped us to make our very own indoor volcanoes! We had a great time and got very very messy!! These volcanoes are so easy to make, you can even make them at home! Try it!

We used a biscuit tin, water, flour, baking soda, vinegar, drinks bottle, washing up liquid and food colouring. First we mixed the flour and water together with our hands to make a thick paste, then we pressed and moulded this to the outside of the drinks bottle.

One person poured some washing up liquid into the volcano. Next, we added some food colouring, some groups used red, green AND yellow!! We took turns pouring baking soda and then a little vinegar into the top of the volcano too. What do you think happened next? That’s right, our volcanoes erupted!! The mixture inside the volcano came bubbling out of the top and spilling all over! The volcanoes were great fun to make, though very messy!

Room 9 and Room 10 went out to the yard to see some more science experiments; we watched excitedly as the scientist made lots of loud explosions , it was brilliant! We all think we’d like to become a scientist when we are older!

Check out our photos to see how amazing it was!

6th Class – Rm 6 – By Oisín It’s a Solid… It’s a Liquid… It’s Oobleck

Ooblek is sticky mixture.It contains corn flour and water.I went home and was making play doh with my brother at home for the engineering project called Technology  for life. He mentioned a substance called ooblek. It is sort of like quick sand. When you poke it quickly it will feel like a solid but when you poke it slowly the ooblek it let you go to the bottom. That is because of pressure when you poke it quick all the corn flour particles are forced together but when you poke it slowly the corn flour particles  have time to move out of the way. Ooblek, quicksand and silly putty are all non-Newtonian fluids. This name comes from a Dr Seuss book called Bartholomew and the Ooblek.  

I brought in some corn flour and Miss O’Donnell let me share this experiment with my class. We carried out the experiment in class and here are some pictures.

Battery Experiment Results–6th Class Room 6

Our experiment has finally finished. Our results were very surprising. The results were that the cheap battery expired after 21hrs and 30mins. The expensive battery expired after 21hrs 51 mins. And the rechargeable battery expired after 26hrs 45mins.

 

In our class all children’s predictions showed that each person expected the expensive battery to last the longest. However our experiment proved us wrong. The majority of children in our class predicted that the that the rechargeable battery would last for the least amount of time. However our experiment proved us wrong again and showed us the cheap battery lasted the shortest time.

 

You can see our class predictions on a previous blog which you can go back and see.
