Junior Infants: Science Experiment

Last week the boys in Room 3 carried out an interesting experiment, which was prompted by our recent weather! It was called “The Snowman’s Coat”.

Having discussed and shared the fun they had in the recent snow, the boys described their many and varied snowman-creations. As they have all since melted, the boys were  asked to think about how they might get their snowmen to last longer! They came up with some very interesting ideas, among them…..

  • put him in the fridge
  • wrap him in an ice-pack
  • make him beside the wall/under a tree
  • put a blanket around him
  • give him a coat and hat

So we decided to carry out an experiment to establish what would happen if we gave the snowman a coat, as some boys suggested. We brought in some snow from the yard and made two small snowmen in our classroom. We tried to keep them the same size, so that it would be a fair test.

We then wrapped one snowman up in a “coat” and placed them side by side at the top of the room. The boys suggested that we would not place them near the radiator or under the light, in the hope that they would last much longer!

The boys predicted what they thought would happen, giving their reasons why. We kept a close eye on our “new classmates” during the day, but before long it became clear that one saucer was filling up with water a lot faster than the other!

Yes, the snowman wearing the coat lasted longer, but can you tell why?

Senior Infants- Science- Space

During the month of January, Senior Infants were learning all about the theme ‘Space’. It was a very popular theme because it was so interesting and lots of fun! We watched some Youtube clips of astronauts brushing their teeth and washing their hair in a space station!! We learned that everything floats in the space station because there is no gravity. We then carried out an experiment to explore gravity on Earth. We held two bottles of water at the same height and predicted which bottle would hit the ground first. We had many different predictions so there was a lot of discussion. We varied the weight of the bottles and also dropped them from different heights to ensure it was a fair test. Check out our photos below to see the results!

We had great fun launching a rocket. We blew up a balloon, let it go and noticed what happened. Next, we discussed ways in which we could control the path in which the balloon was travelling. We then connected the balloon to a piece of string and launched our very own space rocket in the small hall!

We carried out an experiment to discover why there are craters on the moon. To make the moon’s surface we put flour and cocoa powder in a big tray. We used pieces of plasticine as meteorites and predicted what would happen when we dropped them onto the moon’s surface. We changed the size of the meteorites and dropped them from different heights to see if there was any difference in the craters. As you can see making craters was quite messy but great fun!

At the Role Play area we had the opportunity to take on the role of an astronaut in the Space Station.

At the construction area, we made space ships, the planets, rockets space stations using Connects and Lego.

At the Creative Station, we created our own space rockets and flying saucers.

Room 15 – Water Absorbancy

Today, we looked at the topic of absorbency in science. We looked at how efficiently five different brands of kitchen towel could absorb water. The boys compared the performance of these, based on a number of factors, including the number of sheets in each roll.

When the experiment was completed, the boys were informed of which brand each roll was and how much it cost. We integrated a number of maths equations into our experiment to identify which roll represented the best value for money (even if it may not necessarily have absorbed the most water).
