Inquiry-Gears and Pulleys

Over the last two weeks Gemma and I have been working on gears and pulleys for our focus on physics for inquiry this term. I really enjoyed working with Gemma because we have never worked together before and gave a really clear and easy to follow presentation. I learnt some new and interesting facts and found out about lots of different types of gears like spur, helical and the external gear. I also learnt that when you use a pulley that you have to pull four feet down if the object that you are lifting is two feet high. I look forward to learning and finding out more things from our new project.
