We have begun our DT unit be discussing what we know about different mechanisms and how they move. We have practised using specific vocabulary such as – slider, lever, turn, twist, forwards backwards and left and right. We then went on a mechanism hunt around our school to find sliders. Look at our picture to see what we found.
In DT, we have been looking at bridges and their structures. To help us understand the difference between a beam bridge and an arch bridge, we had a go at making both types physically. Year 5 then investigated to see which bridge could hold more weight. We discovered that the structure of the arch bridge was able to carry more weight.
Today we created a mock up of our slider game. We discussed the slider mechanism and used the model to test our ideas and what words would work well.
Today year 5 had an exciting lesson making a truss bridge out of spaghetti. It was great to see everybody working as a team to build their bridges! They were then able to test the strength of their bridge and compare them to the arch and beam bridge that we made last week.
Today we have continued our design and technology project of making helmets, which are shell structures. Our focus today was how we can use layering to strengthen the structure of the helmets.
