Unit 2: How the World Works
Unit 2: How the World Works Central Idea: People use their understanding of natural laws to manipulate objects. We have had quite a busy first term! During this unit we learned about forces and simple machines! We talked about push and pull, and how machines help up use less force to move an object. In the pictures below we were miming push and pull and our friends had to guess which one we were showing! Can you tell if we are showing push or pull? When learning about simple machines we learned about wedges! we made different kinds of paper airplanes to see which were most effective at reducing air resistance! We made our own recycles cars when learning about wheels and axels! Students worked in teams to create their own Rube Goldberg machines to complete a task. A Rube Goldberg Machine is a complicated machine used to complete a simple task. We were also able to have swim lessons this unit! It was great seeing students become more and more confident in the pool. Thank you Ms. Saya
