pitfall



                                                The Pitfall


We did a science experiment that is called a Pitfall, it is a pit used to catch tiny mini-beasts!!
To make the pitfalls we dug two holes and put two inspection chambers in them we put some corn beef  in one and a slice of pear in the other we put four stones around the holes and a piece of cardboard on the top of each .There are two kinds of minibeasts we want to catch a herbivore a fruit or plant eater and a carnivore a meat eater .We plan to catch earthworms snails slugs spiders centipedes milipedes and loads of others too.!

Water Piano

John and Oisin

We did a water experiment last week on the water piano. First we filled a jug with water. Then we put a little   
bit of water into the first glass.


 

                                         

Then put more water into the second glass and so on until we had different levels of water in each glass.
When we were finished we got a dinger and hit it off each glass. When we done that there was different sounds depending on how much water was in the glass.
The glass with the least amount of water made the highest noise and the glass with the most water made the lowest noise.

pulleys

Today we were experimenting with pulleys. Here's how to do it!!!

UTENSILS:Pulley
                             String
                            Scissors
                            Keys
                            Horizontal bar



:
                            
                     
  
STEP 1: Cut a piece of string about 2 meters

STEP 2: Put the pulley onto the keys

STEP 3: Tie the piece of string onto the pulley

STEP 4: Pass the string over the bar

STEP 5: Wind the string around the pulley wheel

STEP 6: Pull!

The Water Cycle


On the 1st of February, our green day of action,
5th and 6th Class did some experiments with water.
One was to get a large plastic bowl, put some water into it, and put a mug into the water (Don’t get any water inside the mug).
Put some clingfilm over the top of the bowl, and tuck it under the edges (Don’t let the film fall off).
Put it outside if it’s hot, if not, put it on a radiator. After a while, the water should evaporate, start to rise up, and hit the film, then some of it should fall into the mug, and this experiment demonstrates the Water Cycle.
The Water Cycle is a never ending cycle, starting with evaporation, which means that when water gets hot, it turns to water vapour, it rises up to the sky, and forms clouds. When clouds get full of water vapour, they turn grey or black and then it starts to rain or snow, (If it’s cold enough). This rainwater goes to the Water Table,
which then flows back to the lakes and streams again, where evaporation starts all over again.

Gummy Bears



In this experiment we used a glass of water and a gummy bear.
We put the gummy bear in the water and left it there over night.
The next day we checked the gummy bear and it was bigger.                
This happens because the water goes from a place of low concentration
to a place of high concentration. The longer you leave the gummy bear in the water, the bigger it will get. This happens through osmosis.
Osmosis is the movement of water in and out of cells.

Water absorption


       Materials
1:Three plastic cups 
2:Kitchen roll
3:Food Colouring

      Method
1: Fill two cups 3/4 full
2: Put two different colours of food colouring in the two cups
3: Get two sheets of kitchen roll
4:Fold them in half
5:Put one side in cup and the other side in the empty cup in the middle and do the same with the other tissue
6:In a while the two cups should make a new colour in the empty cup
7: You can see our results on the blog

Point of experiment
This experiment shows us that tissue absorbs water and puts it into the empty cup
