Water

We have been learning about ‘Water’ in Junior Infants. We investigated whether various objects would sink or float. We also looked at which containers hold more or less water than our basin. We are having fun making our Aquariums in art this week!

Greenwave- Signs of Spring

From the beginning of  February until the end of May we have been collecting information on signs of spring.

1.We were looking for frogspawn in our school pond. The frog is a carnivore, which feeds on snails, beetles, caterpillars, woodlice and flies. Finding frogspawn in a pond or a ditch is one of the very early signs of spring and it can happen as early as February.

2.We were looking out for swallows also. The Swallow feeds on insects which it catches in its beak as it flies through the air.There are no insects in the air in Winter so the Swallow flies off to warmer countries in Africa. Swallows return to Ireland to breed.

3.We looked for the horse chestnut in our school garden. To find the tree remember where you collected conkers last autumn. They have no leaves in early spring but they have very characteristic twigs and buds.

4.We were looking for wild primroses. Primroses grow wild in ditches,hedges,grassy banks and woodland edges. When you start to find them watch every day for the flowers to start growing.

5.We found a hawthorn tree in our school grounds. Many of the hedges surrounding our fields and roadsides contain hawthorn trees.

6.We looked for the ash tree also. It is usually well into may before the ash buds burst. Ash trees are very common in hedges, parks and gardens. They have grey twigs with black buds -the only Irish tree have black buds.

We recorded wind speed using an anemometer, rainfall with a rain gauge and temperature using a thermometer weekly, we blogged our results online.

Making an Anemometer

Making an Anemometer (Measuring wind speed)

  • Scissors
  • 4 small paper/plastic cups (like drinking cups)
  • A colouring pen – any colour
  • 2 strips of stiff cardboard – the same length
  • Ruler
  • Stapler
  • Large drawing pin (thumb tack)
  • Sharpened pencil with eraser on the end
  • Blu tack or modelling clay
  • A hard surface – cardboard or tile
  • A watch with a second hand

 

  1. Cut off the rolled edges of the cups to make them lighter.
  2. Colour the outside of one cup with the colouring pen.
  3. Cross the cardboard strips so they make a plus (+) sign. Staple them together.
  4. Take the ruler and pencil and draw lines from the outside corners of where the cardboard strips come together to the opposite corners. Where the pencil lines cross will be the exact middle of the cross.
  5. Staple the cups to the ends of the cardboard strips; make sure the cups all face the same direction.
  6. Push the drawing pin through the centre of the cardboard (where the pencil lines cross) and attach the cardboard cross with the cups on it to the eraser point of the pencil. Blow on the cups to make sure the cardboard spins around freely on the pin.
  7. Place the blu tack or modelling clay on the hard surface. Stick the sharpened end of the pencil into the clay so it stands up straight.

We counted how many times the anemometer rotated in one minute. It gave us an idea how fast the wind was blowing.

Here are our updated results and averages:

Jan Wk 1 = 4 Wk 2 = 3 Wk 3 = 5   Average = 4
Feb Wk 1 = 6 Wk 2 = 8 Wk 3 = 6 Wk 4 = 4 Average = 6
Mar Wk 1 = 5 Wk 2 = 2 Wk 3 = 4 Wk 4 = 1 Average = 3
Apr Wk 1 = 3 Wk 2 = 5 Wk 3 = 6 Wk 4 = 2 Average = 4
