Science is one of our favourite subjects at Croagh N.S. We have a school garden, and we take part in the Greenwave Project where we learn lots about nature and the weather.

Primroses

These are our primroses which were spotted near Croagh N.S. in March 2014.

 

Some facts about the primrose!

Primroses grow wild in ditches, hedges, grassy banks and woodland edges.

From as early as February check hedges and banks, particularly south facing ones for primrose leaves. When you find them watch every day for the flowers to start growing.

  • They have beautiful pale yellow flowers with five petals and distinctive green wrinkled leaves.
  • Each flower occurs individually on its stalk.
  • They have a lovely cool scent and are impossible to mix up with any other spring wild flower.
  • They usually come into flower around the month of April

This is a horse chestnut tree we visit in the park in Croagh. When we went to see it on March 31st we noticed the buds were beginning to open and the green leaves were bursting out.

This is the horse chestnut tree in Croagh.

Here is some information about the horse chestnut tree from the Greenwave website.

Botanical Information

The Horse Chestnut tree is native to Greece and The Balkan regions. It was brought to Ireland by people who valued it as a parkland and garden tree. It is the first deciduous tree in Ireland to open its leaves in Spring. The sticky brown buds burst in March and the large palmate leaves with 7 leaflets quickly unfold. The flowers follow very quickly and look like white candles all over the tree. The bees love them and visit them to collect nectar to make into lovely flavoured honey. These visits help with pollination.

In autumn the green prickly fruits are very obvious. Inside each one is the nut or conker. Unripe ones are white but they turn a lovely reddish brown when ripened. They are eaten by mice who nibble at the outer shell to get the kernel inside.

Horse Chestnut trees can grow up to 30 metres high and live for at least 150 years.

Temperature

The average temperature at Shannon Airport during the first week of May was 11 degrees. We recorded the temperatures in Croagh every day and calculated the average was 14 degrees.
