Fourth Class STEM Science Optical illusion – 3D Hand 4th Class pupils tried their hands at a 3D optical illusion drawing. We hope you like them! We love to look at them from different angles. Optical illusion – Fish in tank! During the Science Week show, 4th Class pupils watched John Sharpson create a ‘fish in bowl’ optical illusion craft. The pupils thought it looked amazing, so we decided to try it out. First, we drew a fish and a fish tank on separate pieces of paper. Next, we attached the drawings to a straw, back to back. Then, we spun the straw between our hands to see the fish “appear” in the bowl. It is such an effective optical illusion and was great fun. Pupils created many different types of fish, as well as very interesting variations of tank. Check out our pictures above. This is Science Week! 4th Class pupils kicked off Science Week with a live show that celebrated all things Science! The show was hosted by John Sharpson (‘Múinteoir John’ from RTÉ’s Home School Hub). John was joined by special guests, including Jason Smyth (the fastest Paralympian on the planet), Junior Einsteins Science Club and the education team from Castlecomer Discovery Park. 4th Class pupils learned about the communication methods of elephants, the eye, optical illusions, biodiversity and so much more! We look forward to taking part in some more Science Week activities this week. Bubble Wands This week, 4th Class pupils had great fun learning about bubbles. First, the pupils explored what it takes to make a bubble (an outer layer of soap molecules, a middle layer of water molecules and an inner layer of soap molecules). Next, the idea of bubbles and their colour was investigated. It was found that bubbles get their colour from the light waves that are reflecting in the middle layer. Then, we looked into the shape of bubbles. It was very interesting to learn that a sphere is the easiest shape for a bubble, as it holds the most air. Lastly, we set off to work on our very own bubble wands. We used pipe cleaners as our wands, which we moulded into many shapes (circle, heart, triangle, oval, square etc.). We dipped our wands into a solution of water and washing up liquid, before putting our wands to the test. 4th Class pupils discovered that, no matter what shape wand was used, the bubbles always appeared in the shape of a sphere. How amazing?! Technology Volty – the friendly programmable robot! Ms Forde’s 4th Class had great fun putting their coding skills to the test. First, the pupils decided on a circuit track for Volty. Then, Volty had to be carefully programmed in order to follow the circuit track that was set out. This activity was great fun and really stimulated all of the curious minds within the class. If a mistake was made, the pupils re-coded and tried again. It is all part of the learning fun! Engineering Let’s build a bridge – Ms Woods Let’s build a bridge – Ms Forde 4th Class pupils recently learned about various types of bridges, how they are created, supported and where they can be found. We explored a beam bridge, arch bridge, cable-stayed bridge and a truss bridge. Pupils shared lots of their own experiences of bridges and identified bridges here in Ireland, for example the Ha’penny arch bridge in Dublin. Next, the pupils were given the challenge of designing five bridges using books, paper and unifix cubes. Pupils created a single-sheet bridge, double-sheet bridge, arched bridge, walled bridge and corrugated bridge. Unifix cubes were piled onto each bridge in order to test their strength. First, pupils made predictions as to how many cubes each bridge would hold. Then, the bridges were put to the test. 4th Class pupils found the walled bridge to be the strongest, whereas the one-sheet bridge proved to be the weakest. We had so much fun during this experiment! Maths 2D Shapes Ms Forde’s and Ms Woods’ 4th Class pupils have been learning about 2D Shapes. They were set the challenge of creating a shape using lollipop sticks (5 squares), and then had to remove two lollipop sticks to turn their shape into exactly 4 squares. The pupils really enjoyed this challenge! Next, we used the lollipop sticks from our challenge to create some of the shapes that we had been learning about (square, rhombus, rectangle, parallelogram, circle, triangle etc.). When making these shapes, it was very important for the pupils to remember that only the opposite sides of a rectangle/parallelogram are equal, and not all four sides. The pupils did such an amazing job! Angles in the environment 4th Class pupils have been very busy learning about ‘Angles’, in particular acute, obtuse and right angles. Firstly, the pupils used some pipe cleaners to identify angles in their textbook. Then, they put their learning to the test and tried to identify some angles within the classroom. The pupils found that there were a lot more angles within their surroundings, than what they had predicted. This activity was lots of fun! STEM Show and Tell 3D Printing – 5th Class come for a visit! Ms Forde’s 4th Class were very lucky to have had two wonderful 5th Class pupils pop in to talk about 3D Printing. Richie and Fionn were incredibly informative and displayed some amazing pieces of their own work. They even gave some of it away on the day! 4th Class cannot wait to have you both back for another ‘Show & Tell’ later in the year.
