Every second week the year 7 and 8 students from our class go to High School for technology. They are away all day so we get to do different challenges. As we are studying toys through the ages at present, today we have had to design and build a balloon powered car. We are testing to see whose car will go the further-est. We have all had lots of different ideas and had to make lots of changes as we built them. We are trialing different sized wheels and thinking about wind resistance.
