Dublin Science Festival

Click on the link below for information on ‘The Festival of Curiosity’ taking place in the RDS from 25th-29th of July. This unique event will provide an opportunity for parents, families and the public to interact with science as a cultural activity outside of the academic year.

Electricity Hunt in Room 2

Last week we learned about electricity.

We talked about things that use electricity at home and in school.

Teacher gave us stars and we had to put them on things in our classroom which use electricity.

We found lots of items which use electricity!

We talked about electricity safety rules.

We also talked about how important it is not to waste electricity.

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.

Experimenting with magnets: 2nd Class Room 11

Today we learned a little about magnets and how they work. We found out that they only attract certain types of metal, like iron, cobalt and nickel.

Magnets have two poles, one north and one south. Through experimentation of magnets we were able to show that opposite poles will attract, and same poles will repel each other.

We also tested the ability of magnets to work through various materials. We used paper clips and tested to see if the magnets were working through cotton, tin foil, wood, card, plastic and also water. After testing them we then recorded and discussed our results. We had a lot of fun experimenting with magnets.

AND gates – Boolean Logic

We were learning about Boolean Logic today. Basically it is a group of switches that are either turned ON or OFF and they in turn on a light bulb. All of the circuits we have learned about are based on these simple circuits.

We only learned about AND gates today. Check out our photos below to see the circuit we made and how AND gates work.

1) Both switches A and B are OFF. Therefore, the light is OFF.

Switch A = Off, Switch B = off, Light = off

2) Swicth A is ON (1) and Switch B is OFF (0). Therefore, the light is OFF (0).

3) Swicth A is OFF (0) and Switch B is ON (1). Therefore, the light is OFF (0).

4) Swicth A is ON(1) and Switch B is ON (1). Therefore, the light is ON (1).

Here is an AND GATE table:

Switch A Switch B Light
Off (0) Off (0) Off (0)
On (1) Off (0) Off (0)
Off (0) On (1) Off (0)
On (1) On (1) On (1)

6th – Room 6 – Pencil Circuit– by Finn

I watch a show ever Tuesday called Scientific Tuesdays.We were learning about circuits so I went home and researched about them. I watched this on you-tube. I am hoping to complete this experiment in school.

Here is the link for you to watch:

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.
