Engineers Week 5th Class

5th class in Room 7 have been working hard in preparation for the Globe project. We are investigating air pollution around our school. We are waiting for the results of our investigation from the research laboratory. To help us with our investigation we decided to construct a wind vane and a wind anemometer. We worked together in groups to plan and construct our chosen project. We’re looking forward to using our constructions as part of the Globe project.

1916 – Transport

This slideshow requires JavaScript.

 

We looked at how different transport was during 1916.

In our pictures we saw people walking, stage coaches, ships and trams.

One of our photos had a train station in it. It was obvious that it was a train station because it had lots of railway tracks outside it. Molly thought that the train station in her photo was used to transport people to other parts of the country like Sligo, Donegal or Cork.

One of our photos had a ship in it which was delivering cargo to different parts of the country. It was a steam powered cargo ship. Ships used the Grand Canal and the River Liffey to transport their cargo

We looked at a photo of a busy street in the city centre. We thought it was O’Connell Street (Sackville Street) because it was very busy. From looking at the photo of the city people got to work by walking. We agreed that most people walked because they could not afford a car.

One of our photos was taken in Terenure. There were trams in this photo of Terenure. We knew it was a tram because it was shaped like a bus but it had train tracks like the luas. We thought that the tram in our photo was being used to get people in and out of work in the city. Adam told us that there are no trams at all in Terenure today.

Heart Rate (bpm)

Today in second class we all monitored our heart rate with the heart rate monitor.

Our hearts are pumping at a regular rate. This pumping can be felt by placing fingers across the pulse point at the wrist or the neck, and the rate can be counted. An adult’s heart rate is around 70 beats per minute, and a child’s is a bit higher. Heart rate increases with exercise so that more of the oxygen carried in the blood can reach the muscles. The fitter you are, the quicker your heart rate returns to normal.

BPM stands for beats per minute.

Click on the link and you can see a graph showing Jakub’s Heart Rate

This link shows Jakub and Ava’s Heart Rate. Ava’s heart rate was around 92 bpm and Jakub’s was around 73bpm.

We hope to do some exercise tomorrow and monitor our heart rates after. They should be higher than they were today!

The Science of Flight

Investigation 1

What did we investigate?

We wanted to find out which would fall to the ground first, a square piece of paper or a ball of paper?

What predictions did we make?

Because both the pieces of paper were the same size before we rolled one up we thought they might fall hit the ground at the same time.

What did we do?

Science exp.1 003

What did we discover?

We found out that on every attempt the ball of paper hit the floor first.

Why was this?

We felt that the air was stopping the flat sheet from falling and slowed it down.

Further investigations?

What is Air?

How does it stop the flat page?

What is Air?

Air is an invisible gas made up of 78% nitrogen 21% oxygen and 1% of lots of different gases. Air is everywhere on Earth. The further up you go the less air there is.

 What is a gas?

A gas is a state of matter. In a gas the atoms aren’t tightly pressed together. Gases are all around the atmosphere. Vapor and gas mean the same thing but the word vapor is used to describe gases that are usually at room temperatures.

Investigation 2 What is Air

What is Air?

(States of matter)

What are we investigating?

  1. If Air is a gas what is a gas and what are the other states of matter?
  2. What is the difference between them?
  3. How can we demonstrate the three most common states of matter?
  4. How can we change the states of matter?

What did we do?

  1. We looked at the how the atoms are different in a liquid solid and gas.
  2. We looked at ice water and steam as an example of solid liquid and gas.
  3. We tried to turn change the state of the water from solid to liquid to gas and back to solid again.

What did we find out?

  1. The atoms is in a solid are closely packed together.
  2. The atoms in a liquid are not as close together and move freely
  • The atoms in a gas are really loose and fly about easily.
  1. If we heat ice (solid) it turns to water (liquid) and if we keep heating it turns to steam (gas) and if we then catch and condense the water and put it in the freezer we can turn it back to ic ice

RDS Primary Science Fair 2015 – Saturday the 11th of January

On Saturday the 11th of January we had the pleasure of participating in the RDS Primary Science Fair. The RDS Primary Science Fair is a national science exhibition. All 32 counties on the island of Ireland are given the opportunity to present at the fair and in October are asked to submit an application of interest for the event.  Out of approximately 3300 primary schools only 120 schools were selected to present at this years event. This is approximately 3.6% of the primary schools in Ireland.   We felt honoured and privileged to be given the opportunity to present our science investigation at the 2015 RDS Primary Science Fair.

Our Project was entitled: “Why don’t planes fall from the sky”

Check out details of our project in here:

Part 1

Part 2

Part 3

Below is  some of the comments we blogged live during the event:

“Today we are at the RDS primary science fair. We were walking around and we have chosen a few projects that we have liked .we have received some great comments from people who have come to see what we have been doing such as parents , judges and guests.”

Volcano Experiment

We have been learning about the effects of heat.
A few weeks ago we made play-dough in our school kitchen.

Last week Tristan used play dough to make a model volcano.

Ms. McGinley has been teaching 4th Class all about volcanoes.

We learned about the different parts of a volcano.
The burning liquid inside the volcano is called “magma”. When it flows out of the volcano it is called “lava”.

We learned about the volcano in Yellowstone National park in North America.
Other places that have lots of volcanoes are Hawaii and Iceland.

We learned about the eruption of Mount Vesuvius in 79 AD which destroyed the city of Pompeii in Italy.

We conducted experiments with Ms. McGinley to see how a volcano erupts.

We needed the following equipment:

  • a bottle with the top cut off
  • play dough to make the shape of the volcano
  • baking soda
  • vinegar
  • red food colouring

Tristan and Sean filmed the experiment last week.

Step 1: Sean poured a small amount of vinegar and red food coloring into the bottle.

Step 2: Tristan poured a spoonful of baking soda into the bottle.

Watch what happens when the vinegar and baking soda combine in our video.

The chemicals in the vinegar react to the baking soda. The mixture fizzes up and pours out over the sides of the volcano, just like when lava pours out of a real volcano during an eruption.

We really enjoyed this experiment even though it was very messy!

Global Warming

 

Pupils in 4th and 6th Class have been investigating the effects of heat.

One student has been researching global warming.

This is a phenomenon which affects us all.

 

Global Warming Solutions

The Earth’s temperature has risen considerably since the middle of the 20th century. This is because of an increase in greenhouse gases.

Greenhouse gases are created every time we use electricity, drive our cars and create something in a factory.

 

 

This video shows how greenhouse gases are increasing the Earth’s temperature.

Global warming will negatively affect life of Earth in a number of ways.

Polar Bear by Carla Lombardo EhrlichIt will cause the polar ice caps to melt destroying habitats.

global-warming-is-goodIn approximately one hundred years the countries with normally rich and moist soils will become deserts.

A-flood-sign-warns-of-flo-001The melting of the polar ice caps causes the sea levels to rise. This in turn causes a increased risk of floods and tsunamis.

We all must work together to protect the environment and try to reverse the effects of global warming.

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.
