Science
Living Things Investigations:
6th class conducted a sceince experiment to examine the different colour pigments found in leaves, following on from their Tree investigations for National Tree Day. These pigments are responsible for the beautiful variety of colours that we see in leaves during autumn. We used a number of techniques to extract the pigments from the leaves, such as cutting, mashing and soaking them in polish remover. We then used strips of paper towels to absorb the pigment from the liquid and left them to dry. When the paper was dry, we observed the green, yellow and brown colours that represent the three main pigments found in autumn leaves.
Investigation: To extract DNA from a strawberry:
This science experiment is to extract DNA from a piece of fruit - A strewberry, banana or a kiwi worked the best.

Water density experiment: remote learning 2020 (5th and 6th class):
Energy and Forces Investigations:
Balloon investigation: Chemical energy (CO2 created) and it rises up into the balloon, causing inflation (2nd class):
Chemical Energy investigation: Creating CO2 to extinguish the flame of a candle (5th and 6th class)
Investigation 2: Is there enough CO2 in our exhale breath to extinguish a candle's flame? (5th and 6th class)

Environmental Awareness and Care Investigations:
5th and 6th class spent this afternoon in our outdoor classroom investigating and classifying leaves from all the trees on our school grounds. They then did some beautiful leaf rubbings. A great way to celebrate National Tree Day. They have also collected lots of acorns and chestnuts which they are planting out in pots at the moment. This is such an important part of environmental care and our Green Schools philosophy. It was also good for everyone's wellbeing to spend time outside on such a beautiful day. Tomorrow we are planting some trees that have been gifted to us. More pics tomorrow. PS Thanks to Belturbet Men's Shed who made this lovely seating area for us a couple of years ago. It has really enhanced our outdoor space
Nature walk in 3rd and 4th class:
Tree leaf identification and tree rubbings in 2nd class:
Litter and waste: Exploring what can and cannot go into each bin: 2nd class:
Using recycled materials (caring for the environment - reusing) to create artwork. Animal pictures, castles etc.
Space Week activities:
1. Newton's Third Law of Motion:
3rd and 4th class rockets:
Investigation title: Make a paper rocket powered by alka seltzer and water to demonstrate Newton's third law of Motion.
Science behind the investigation:
When you mix the alka seltzer with the water, a chemical reaction takes place between the citric acid and sodium bicarbonate contained in the tablet and the water. This chemical reaction creates a carbon dioxide gas. This carbon dioxide builds up in the closed container and since the lid is the weakest point of the container, the lids pops off and all the carbon dioxide gas escapes out of the container. This is an example of Newton's Third Law of Motion - Every action has an equal and opposite reaction. The carbon dioxide escaping out of the end of the container (the action) causes your rocket to move in the opposite direction (the reaction).
This is how rockets work. Rockets use pressurised fuel and an oxidiser. When the fuel (liquid hydrogen) and oxidiser (liquid hydrogen) combine as they burn into a gas causing an intense pressure which is released through a tiny hole at the bottom of the combustion chamber called a nozzle.
Conclusion:
For every action there is an opposite and equal reaction - Newton's Third Law of Motion.

2. Solar system model:
2nd class:
Read about NASA space station and researched and discussed NASA's Apollo 11 where the first humans walked on the moon.
Watched the recorded live launch of Apollo 11
Identified the planets (order) and the structure of the solar system.
Created 3D models of the solar system.
Drew the order of the planets in the solar system into their SESE copies.

Science Week activities:
2nd class participated in an online workshop for science week with Cavan Monaghan Science festival.
The virtual event took place via crowdcast and was presented by Horrible Science books author NIck Arnold.
Investigations included exploring the concepts of friction and gravity . Nick also explored the world of dinosaurs and discussed his life as an author. He told the pupils about how he began writing and the process of writing the horrible science books.
