STEM in Scoil Barra STEM Links and Information for Parents STEM Around Our School Engineering in the Language Class.. Check out our pictures of the planning stage of designing and engineering a house. Next, we cut out our windows, doors, roof, chimney etc and finally we brought our design to paper. Each design, albeit with all the same items, looks completely individual. We love them! Science – Sink or float? The Language Class investigate… We made an origami boat, checked to see if it would float and then we added in 41 teddy bears until it sank. We had so much fun! Then, we found two teddy bears that sank to the bottom of the sink, but they did not sink when they got into the boat. We really like paper boats in our class.
