In Ms. Ryan’s 1st Class we investigated different materials to see which ones were waterproof. We used Buster the puppet to help us. We predicted if the following materials were waterproof; rubber, cotton, nylon, plastic and tin-foil. We recorded our predictions.
We tested the materials by wrapping a piece of each one around Buster’s arm. Buster’s arm was dipped into the water for thirty seconds each time. We then checked to see if his arm was wet or dry. If his arm was dry it showed us that the material was waterproof. Sadly, poor Buster got wet when we tested the cotton, nylon and tin-foil as these are not waterproof. We would not recommend using these materials when making a raincoat.
Using blocks, paper, books and crayons to test we designed bridges to see which ones were stronger and could hold the most amount of crayons. We manipulated our structures to increase their strength by folding the paper used, using double layers of paper, creating arches and structures for extra support.
The material from which a structure is made is important but you can strengthen a material by changing is shape. Bridge designers often use different shapes for example: arches and triangles. The curve of the arch spreads the load on the bridge and makes it stronger.
Spring showers can only mean one thing for our floors inside our homes…PUDDLES! First class put their thinking caps on today and came up with an experiment that would test which material would clean up puddles best. They made a prediction and then carried out the experiment to establish a result. Each of the children made sure to measure the water and the size of the materials carefully. It is so important that each test is fair so that the result is accurate.
Not only did first class discover whichmaterial absorbed best, they also discovered that playing with water is lots of fun!
We investigated which butter or margarine would go off first. Materials Zip lock bags Spoon Butter/Margarine (Pure homemade butter, Dairy gold butter, Dairy gold Original Flora, Low Low, Benecol, Heavenly Buttery, Stork margarine) Our Hypothesis Pure butter will go … Continue reading →
We were honoured to have the Minister of Education Richard Bruton launch the policy and implementation plan for STEM in education in Ireland. Minister Bruton had the chance to talk to come of the students about what they have been learning in science and maths. Here are a few pictures from the day.
We have loved doing lots of experiments this week for science week! We have been busy exploring different materials that float and sink. We predicted, tested and recorded our results. We especially loved doing the “Dancing Raisins” experiment and designing our own boats! We tested our boats by counting how many “passengers” it could hold before sinking.
We had great fun in fourth class today investigating friction. We tested a variety of different surfaces to see which had the most friction. We rolled a toy car down a slope and and then measured the distance it travelled … Continue reading →
In Room 4, we have been very busy looking at how heat can change things.
We have discovered that when you make a solid hot, it usually turns into a liquid. We observed ice melting into water and we saw how jelly cubes melt into a liquid when you add hot water.
Because there are so many class birthdays in November in our class, we wondered if there was a way for us to melt our jelly cubes quickly. We decided to melt 6 big cubes of jelly and then melt 28 tiny jelly. We monitored our water temperature using a thermometer and we made sure that we used the same amount of water in each bowl. We all made our predictions, then our race began!
