Class 2 have ended the year in style with a fantastic design and technology unit called ‘Wheels and Axles’. During this unit we have learnt about the parts that make a wheeled vehicle move and then experimented with ways to create axles, wheels and axle holders and how to attach them to a chassis. Finally, we designed and made our own moving vehicles. This project has been a great way for the children to develop their resilience and problem solving skills.
What can you make if you have a cup, some sellotape, felt-tip pens, a motor, a rubber, a battery and some crocodile clips? That’s exactly the question which was posed to class 4 last week! It wasn’t much to go on, but then they were given a prototype of a “Scrawler”
A Scrawler is an automatic drawing robot! A motor on top of the robot spins with an offset weight, causing it to vibrate. As it vibrates, the pens making up the “legs” of the robot wobble across the page and draw patterns as they go.
Class 4 wasted no time in taking the prototype to pieces to discover how it worked. With no further instructions, just some reverse-engineering, small teams got to work building a Scrawler of their very own!
Once we had perfected and tested our own versions, we took them apart for a further challenge. Was it possible to teach Class 3 how to make one of their own, without using our hands? That meant no pointing or touching, and no getting frustrated when somebody else was doing the wrong thing! With only 20 minutes to complete the project time was not on our side, but I think the gallery below proves our success!
