Each show sees host Neil Delamere risk life and limb to celebrate the greatest ‘Eureka Moments’ of our time – he channels 4 million volts of electricity and shoots lightning out of his fingertips (and a couple of other places while he’s at it), he creates an earthquake in Westmeath, undergoes astronaut training in a human centrifuge and goes freediving in a freezing quarry – all in the name of science.

Eureka! The Big Bang Query was made with the support of Science Foundation Ireland and the Broadcasting Authority of Ireland.

Things To do
1.    Grow Celtic Cress (this will take about 4-5 days).

What you will need:
1.    Cress seeds, paper towels and a flat plate.

What to do:
1.    Download the Celtic Cress worksheet below and cut out the first initial of the student’s name.
2.    Wet some towels until they are soaking.
3.    Lay the letter shape onto the towels.
4.    Sprinkle lots of cress seeds in the letter shape. Make sure you cover the whole of the letter shape. Press the seeds down gently.
5.    Lift the letter shape, leaving the seed shapes. Place the plate in a warm sunny spot.
6.    Use a spoon to water around the letter shapes every day. Don’t put water on the seeds.
7.    Watch them grow (around 4-5 days). When the cress is as long as your finger, cut it off and eat it!

Things To do
1.    Download the Flower Parts worksheet below and name the parts of a flower.
2.    Grow a plant from seed (this will take about 2 - 3 weeks).

What you will need:
1.    A clean glass jar, paper napkins

What to do:
1.    Rinse the jar in cold water. Empty it out - but do not dry it.
2.    Fold a paper napkin in half, curl it into a circle and slip it inside the jar.
3.    Press the napkin against the side of the jar (let it soak up the remaining water residue).
4.    Peel back part of the napkin and push three seeds (broad bean seeds are good for this) evenly spaced around the inside of the glass jar.
5.    Wet the napkins with lots of water.
6.    Put the jar in a bright warm place (the windowsill is perfect!).
7.    Add water often to keep the napkins wet.
8.    The roots will start to grown first and then the shoots.

Things To do
1.    Download the Famous Buildings worksheet below and ask the children to name the buildings in the pictures.
2.    If possible, take pictures of local landmarks and do a mini 'show-and-tell' about the buildings.
3.    Ask the children to draw a picture of a local landmark and do a mini 'show-and-tell'.

This website documents a project in which six County Sligo schools explored and documented the heritage sites of the county. It has lots of resources that can be used by other schools in Sligo.

Things to do
1.    Visit a local forest - you can find a list of forests and trails in your area here.
2.    Here you can download information and worksheets about trees. These worksheets are suitable for primary school children and are a fun way for children to learn about trees and the environment. Learn more about trees here.

This project was developed in partnership with the Kilkenny County Childcare Committee, Kilkenny Education Centre, Dig-it-Kids, and with co-funding from the Heritage Council.

This plant grows commonly in lawns and fields. Early in the year only its leaves are obvious. These are described as trefoil leaves - three leaflets from one stem. These trefoil leaves are easy to find and to recognise. Each leaflet is heart shaped with a pale V-shaped mark. The Irish word for clover is seamair. In spring when there are no flowers out yet, the leaves are young clover - seamair óg or shamrock.

There is a tradition that St Patrick used the leaf of the shamrock to illustrate his teachings about the Holy Trinity to the Irish people long ago. Just as there were three leaflets united in one leaf of the shamrock - so were the three deities of the holy trinity united as one God. To commemorate this, Irish people wear a bunch of shamrock in their lapels on March 17th - St Patrick’s Day.

The plant begins to flower in April and there are white clover flowers all summer long until the end of September. The white clover flower head is actually a cluster of small individual flower heads. The flowers can be visited by honey bees who gather the nectar to make particularly delicious clover honey. As the clover is a member of the pea family, its seeds are carried in pods.

Clover was planted by farmers in their pastures to improve the fertility of the soil. Plants need nitrogen in order to grow and usually, to get a good crop, the farmer must add nitrogen as a fertiliser to the soil. All members of the pea family - including the clovers - are able to take in the nitrogen from the air and use it to grow. They are able to fix nitrogen in this way because they have special nodules on their roots. These nodules are formed because the plant can form an association with a particular type of nitrogen-fixing bacteria and together the plant and bacteria work in a symbiotic relationship to fix nitrogen from the air. Thus, in the days before farmers had large quantities of cattle slurry to restore the nitrogen levels in their soil, they were very glad to plant clover and let it improve the nutrient quality of their soil.

Things to do with Senior Infants
1.    Around St Patrick’s Day, the class can be brought out to collect shamrock from the school lawn or field. They can be told about the tradition of St Patrick and the shamrock.
2.    In May or June the class can go out to look for clover in flower. White clover has obvious white flower heads. Pupils may also find red clover which has purple flowers which are larger than those of the white clover. They may also find small yellow clover flowers. These belong to a different species - yellow clover - which grows in the drier parts of grassland areas.

Skills and concepts development:
Children should be able to:

1. Time and Chronology:

• Describe events as before/after/, later/earlier
• Use a simple timeline
• Use dates such as 1681

2. Change and continuity:

• Recognise how the castle has changed at different periods
• Identify features that have remained the same

3. Cause and effect:

• Recognise the link between the site of the castle and the need for the lord and soldiers to defend themselves in the early centuries of the castle.
• The importance of displaying a coat of arms for a family.
• Recognising how people’s needs change and the impact that has on a building, for example the moat being filled in and the change in the design of the windows.

4. Using evidence:

• Visiting and examining the building

5. Empathy:

• Imagine and discuss the feelings of the servants working in the castle.

Methodologies:
Among the methods which may be used are:

• Story lesson about the Butler family
• Comparing a modern photo of the entrance to Kilkenny Castle with an 18th century
• painting
• Exploring the environment, using the trail
• Integration with other subjects: geography (limestone), art (designing coats of arms), maths (shape)

Woodlice feed on dead plant material such as dead leaves, rotten wood and dead plant roots. They play a very important role in the food chain as the nutrients locked in the plants are broken down and released by their activities. This is why they are so abundant in the leaf litter at the bottom of a hedge or in woodland. They in turn are part of the food chain, being eaten by spiders, pygmy shrews, hedgehogs and any bird sharp-eyed enough to see them. We have over 20 different species of woodlouse in Ireland — one called the pill bug is able to roll itself into a sphere when disturbed and this helps it to evade capture.

Things to do
1.    Do woodlice prefer light or darkness?
Get a shoebox. Have half the box covered with a lid. Put six of the woodlice into this box. Have a second similar shoebox with no lid as a control to show that you are doing a fair test, and put the other six in there. Come back later and observe where the woodlice are. They will all be in the shady side of the box.
2.    Do woodlice prefer damp or dry?
You can set up a similar experiment with the two boxes only this time no lids on either but a damp sponge in one section of one of the boxes and a dry sponge in a different section. Put two dry sponges in the second box. Put six woodlice in each and observe what happens. Are there more woodlice at the damp sponge than at the dry sponge?

This means that there is a queen and a colony of workers that live together in a nest. The queen hibernates for winter and in March wakes up. She emerges, chooses a nest site and begins to build a paperlike nest from chewed up timber. This nest can be in a hedge, in an attic or roof space, or in a disused shed. She lays eight eggs and when the eggs grow into worker wasps they take over the running of the nest. The queen goes into egg production full time and the workers build six-sided cells for the eggs. The workers are all female and they feed the baby wasps with chewed up greenflies, aphids and other insect garden pests. The adult wasps, on the other hand, feed on a sweet-tasting substance excreted by the grubs in the nest.

So all summer long from April to August, wasps do a great deal of good, keeping down the numbers of harmful plant pests. By the end of August, the queen will have laid up to 40,000 eggs and is beginning to tire. The nest can be the size of a football by now. The workers build different shaped cells in which eggs are laid that go on to be queens, while different shaped cells again cause her to lay eggs that produce drones.

These all leave the nest when mature, mate with those from other nests and the newly fertilized queens go into hibernation at once and emerge to start the cycle all over again next March. The old queen back at the original nest lays a last round of eggs and dies by the end of August. This last round of worker wasps have no younger babies to feed with insects, nor indeed any grubs to lick sweettasting liquid from. It is these last wasps during the months of September and October, for the six weeks lifespan that they have, that have to hunt everywhere for sweet food. They can eat nectar from flowers, or suck the juices of fallen apples and blackberries. But many of them do come into our homes seeking sugar there.

Of course they will sting if assaulted by an angry or terrified human. But they don’t seek us out deliberately to sting us. By the end of October, they will all have died. The nest is empty and won’t be used by next year’s queen. The whole cycle will begin again the following March.

About their sting — the sting of a wasp is like a needle and can be withdrawn after it is used in order to sting again. The bee has a sting with a serrated edge which gets stuck in our thick skin and cannot be withdrawn so a bee is torn apart as it tries to withdraw it from a human and will later die.

Things to do
1.    Get hold of a disused, empty wasps’ nest. Spray it with hair spray to render it less brittle. Bring into school and let the class examine the nest in detail. It can be cut in half in due course so that the intricate cell structure can be appreciated.
