The teddy bears in Junior Infants were delighted that a team of architects and engineers designed and built them some lovely new homes. Watch out Dermot Bannon!
We have been experimenting and testing the force of water on objects by investigating things that float and sink.
To begin we collected a variety of items from around the classroom to investigate. As a class we predicted which items would sink and float in water. Next, in our groups, we took turns to test the items to see if they would sink or float. Lastly we sorted the items into two groups; sink or float and we recorded our results.
The second activity we completed was ‘Design a Boat’. Firstly we experimented with a ball of plasticine to see if it would sink or float and if changing its shape would make a difference. Then in our groups we tried to use the plasticine to design a boat that would float. If we were successful we tested our boat to see how many ‘passengers’ (dried peas) it could carry. After a few attempts some groups were successful! 🙂
The last activity we completed was an experiment called ‘Dancing Raisins’. We predicted what would happen to the raisins in water and in soda water and then observed the differences between the two types of water. We were amazed to watch the raisins begin to ‘dance’ in the soda water! Why do you think this happened?! 🙂
Check out our Eco-friendly bags now on display in ‘Les Fleurs’ flower shop in Harold’s Cross. They are so easy to make, check out our video in the post below!
Check out this video we made to show you how to make Eco-friendly bags, why not get creative and make a bag to go along with your Easter Bonnet this year!
Take a look at our Eco friendly bags. We researched gift bags and discovered that the majority of them are made in China. We wanted to reduce the air/land and sea miles used and thereby reduce our carbon footprint by making bags of our own using old newspapers.
Task: Design a bridge
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.
Great team work and lots of fun constructing the tallest tower.
