STEP 1
Environmental Awareness and Care
This is a sample of some of the conservation & environmental awareness projects completed in our school this year. These projects were done by 3rd class, they created a fantastic display which we were all able to learn from. Well done 3rd class, fantastic work!!
Senior Infants Science Experiment
Strand:
Materials. Strand Unit: Properties and
characteristics of materials
Experiment: Investigating which materials are
waterproof.
In November, our
theme was The Fire Station. As part of this theme, we wanted to find out what
kind of material would be best for making wellington boots. After much
discussion we concluded that the best material would be waterproof. To this end
we investigated which of four materials, kitchen roll, newspaper, card, or tin
foil were waterproof. We wanted it to be a fair test, so we decided to put the
same amount of water on each material. After making predictions, all the
children tested the materials with one teaspoon of water and the discovery was
that tin foil was the best of the three. To take the experiment further we
decided to see if any of the materials was inflammable as this was also deemed
to be an important property of boots. Only the teacher conducted this part of
the experiment, but all pupils observed. Tin foil again emerged as the only
inflammable material.
The children then
completed a worksheet recording their discoveries.
Living Things
Energy and Forces - SPACE WEEK ACTIVITY!
Launching!
Junior Infants- Mrs. Keane
Rocket Launch 1
Equipment: Large balloons (long shaped) (Round ones
will work but the long balloons
look more like a
rocket.), Balloon pump, String OR cotton thread OR fishing
line 3-4 m long,
Drinking straw, Clothes-peg, Sellotape, Two chairs
Preparation: Collection of materials
The air coming out
of the back of the balloon pushes the balloon forward. This is
how rockets work –
the hot burning gases rushing out the back of the rockets
push them
forwards.
Skills: Investigating and experimenting
Activity:
·
Blow
up a long-shaped balloon and let it go. Notice what happens. (The balloon will
travel off in random fashion as the air rushes out the back of it.)
·
Now
control the path of the balloon by connecting it to a piece of string. (The balloon
will whiz along the string).
Safety: Care with the string.
Rocket Launch 2
1. Blow up a long-shaped balloon and let it
go.
2. Notice what happens.
3. Pull string through a drinking straw.
4. Tie the string to two chairs and pull it
tight.
5. Blow up a long-shaped balloon and keep the
air in it using a clothes peg.
6. Using sellotape attach the balloon to the
side of the straw.
7. Pull the whole thing back to the beginning
of the string and take off the clothes peg and
8. Launch your rocket!

Testing the effect of air pressure.
Equipment:
matches, glass, candle, plate, water, food colouring
Steps:
1) Fill the plate with water and add food colouring
2) Light the candle and place in centre of plate.
3) Place glass over the lit candle
4) When the candle is extinguished due to lack of oxygen the water level inside the glass will rise.
Reason for water level rising: When the glass is placed over the lit candle it causes the air inside the glass to heat up. This lowers the air pressure inside the glass. Therefore the air pressure outside the glass is greater than inside the glass. When the candle goes out the greater air pressure outside the glass forces the water inside the glass causing the water level inside the glass to rise.
Variations: Use various amounts of water, Use more or less candles, use a bigger or smaller glass to put over the candle.
Maths: Measure the liquid, time how long it takes the candle to
extinguish, measure how much the liquid rises inside the glass
