Floating Cork, Wednesday, 12th March, 2008
When we put a cork into a cup of water, the cork always tries to float over to the edge of the cup.
We tried this lots of times, but the cork floated to the edge of the cup each time.
Teacher filled the cup up to the top, and then added even more water.
The water bulged at the top of the glass (the bulge holds because of surface tension). Now the cork floats in the middle of the cup.

Scoil Chaitríona Junior is taking part (for the first time) in the Féile Scoildrámaíochta. Well done to the two classes who took to the stage in the Temperance Hall in Loughrea on March 4th. Here are the terrific results:
- Ms. Lavery's class (1st) came 1st in their group with their drama Na Trí Mhuc (The Three Little Pigs)
- Ms. McLoughlin's class (senior infants) are through to the Connacht finals in Castlebar at the start of April with their play Codladh Céad Bliain (Sleeping Beauty)
- Victory Adebayo from Ms. McLoughlin's class won a Best Actress Award for her part as the evil fairy in Sleeping Beauty
- Scoil Chaitríona Junior won the award for the best newcomers to the Féile
A very hearty CONGRATULATIONS to all who were involved in both plays, and especially to Mr. Len Wright for his help with the wonderful sets and props, and to Anne Power for her expertise with all our make-up.

We tried newspaper too. It soaked up a little water but not much.
Next we made towers with one cube on the bottom, then another layer of something to test, then 2 more sugar cubes. We tried sponge, paper towel, newspaper, tin foil, cardboard, card, cling film and plastic in between the cubes of each tower.Our experiment didn’t work too well. We found that the sugar cubes dissolved faster than they could absorb the coloured water through any material but paper towels.
When the sugar cubes dissolved, the whole tower fell over and the cube on the top absorbed the coloured water as soon as it touched the water.

This is an ordinary balloon that we can easily blow up.
If we put it inside a bottle it doesn’t blow up so easily. Why not?
When we put the balloon in the bottle there is air in the bottle already. We can’t blow up the balloon without moving the air that is in the bottle already, and there is nowhere else for this air to go. It is impossible to blow up the balloon.
When teacher cut the paper in two along the coloured line, we ended up with still only one strip. Magic? No, science
