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.

Investigating Thermal Conductors

Pupils from 4th and 6th class have been investigating the effects of heat.

Here are the recordings of one of these students:

Last week I did an experiment about heat.
A thermal conductor is something that lets heat pass through it.
My investigation was to find out which material the best thermal conductor.

The materials I tested were:
• wool
• plastic
• metal
• wood

The other equipment I needed was:
• 4 mugs
• kettle
• water
• butter
• pasta
• spoon

I predicted that metal would be the best thermal conductor.
This was correct because the butter and pasta melted on the knife the quickest.
I noticed that when the butter fell in the water it changed into liquid. I also noticed that the wool was the only material to absorb water.

A note from Ms. Ni Dhalaigh:

If you would like to carry out this investigation at home make sure you have an adult to help you with the hot water. Be very careful!

Handwashing training in Room 9

On Wednesday a nurse from the Hospice called Libby came to visit our class. She read a story to us about a girl called Janey. We all had to say “Janey, wash your hands!” when she got her hands dirty or sticky, after she was playing in the garden, after she went to the toilet, when she petted her pet poodle and before she ate something. Libby taught us how to wash our hands properly and she gave us fake germs to put on our hands. Then she showed us a glow box. We all put our hands, one by one, in the glow box and saw white lights on our hands, which were the fake germs. When everyone had put their hands in the glow box, we went out to wash our hands to see if we could wash off the fake germs. After that we put our hands back in the glow box to see if we had washed off all of the germs. Libby showed us the places on our hands where we get most germs on a big poster, so that we know the important parts of our hands to wash. Before she left, Libby gave us each a little cartoon germ to remind us to wash our hands and a certificate to say that we have successfully completed our handwashing training.

Forces in Room 12

We investigated forces in Room 12. First of all we discussed the difference between a push force and a pull force. We also discussed friction. Friction is a force that slows things down. We came up with examples of push, pull and friction forces we use everyday in the classroom.

We then discussed how forces can be measured using a Newton Meter. The Newton Meter reads how much PULL force it takes to make something move and it is measured in Newtons (N).

We worked in pairs and investigated how much pull force was needed for our partner’ s runner. We also investigated the following objects around the classroom;

A chair: 8.5 Nscience 002

A dictionary: 1.5 Nscience 001

The crayon box: 0.5 Nscience 003

A school bag: 9.5 N

The school bag needed the MOST pull force while the crayon box needed the LEAST.

 

Materials -The Hovercraft in Room 12

In room 12 we made our own hovercrafts. First of all we had to learn a little bit of information about the hovercraft. It is a vehicle that glides over sea or land on air. Although it is heavy, the air beneath it holds it up. It is often used to rescue people and can travel faster than a car!

Equipment needed to build our hovercraft; a CD, a balloon, a sport’s bottle, sellotape

Method:

1. Our teacher cut the top off our sport’s bottles.

2. We then taped the bottle top to the centre of the CD.science 006

3. One person in each group inflated the balloon.science 005

4. When the balloon was inflated, we closed the valve on the lid and placed the balloon over the lid.science 007

5. We then carefully opened the valve.science 004

Our Results:

-The hovercraft glided across the table

-The air came from the balloon and  lifted up the hovercraft

-The hovercraft hovered on a cushion of air

 

Shining Bright in Room 10

In Room 10 we have been learning about energy and forces. We have been investigating light.

Room 10 Blog 002
First we brainstormed things that give us light. We call these light sources. We learned that the sun is the biggest light source in our galaxy.

Room 10 Blog L & R 272Light sources: fairy lights, a torch, light bulbs, candles, safety lighters.

Then we learned about things which reflect light. We call these reflectors.

Room 10 Blog L & R 275Reflectors: tinfoil, mirrors, high visibility clothing, medals, coins, DVDs.

We learned that reflectors don’t light up themselves – light sources shine onto reflectors and the light bounces off them, making them look shiny.

We learned that the moon is a reflector. It doesn’t really shine – it reflects the light coming from the sun.

We brought in objects from home and tested them to see if they reflect light. Some of the objects were reflective, but some were not.

Room 10 Blog L & R 286The jewellery box was reflective.

Room 10 Blog L & R 291The envelope was not reflective.

We also learned about things that are transparent. If something is transparent it means you can see through it.

We brought in things from home which are transparent.

Room 10 Blog L & R 283Transparent objects: ziplock bags, make-up bags, plastic bottles, water.

We investigated the transparency of the following items: paper, tissue, tinfoil and  greaseproof paper. First we predicted which ones would be transparent and which would be non-transparent or opaque. Then we tried to trace a picture through each of these materials.

Room 10 Blog 001Here are our predictions and our results.

Here is a gallery of all of our investigations.

Sunflowers.

June 2013 022We have been very busy in Room 2!

This month we planted sunflower seeds.

ImageWe recycled our milk cartons to plant the seeds in.

We learned that seeds need soil, water and sunlight to help them grow.Image

ImageImageFirst we put some soil into our cartons. Then we made a little hole for our seeds. Next we covered the seeds with more soil. Then we watered the soil. Last, we put our cartons on the window sill so the sun will shine on them and help the seeds to grow.

We really enjoyed planting seeds with our teacher!
