How The World Works Summative Assessment

Last week, the students in Grade 3 demonstrated their knowledge and understanding of forces and motion to create compound machines for their How the World Works summative assessment task. Students worked in small groups to create a machine that would make work easier.

In addition to demonstrating their knowledge and understanding, the third graders also demonstrated some very positive PYP attitudes. They all showed great independence, cooperation, creativity, and commitment. They were also reflective and amazing thinkers and communicators.

  

  

 

Field Trip to the Science Museum

For their How the World Works unit of inquiry the students in Grade 3 have been learning all about how simple machines use force and motion to make work easier.

This past Monday, the third graders went on a field trip to the Science Museum to see first hand how forces create motion and how simple and compound machines reduce the amount of force required to do work.

Students had a ton of fun in the museum's Machine Room, where they used a variety of levers, pulleys, screws, inclined planes, etc. to move some massive steel spheres around the room.



Students came away from the field trip with a greater understanding of simple machines and the ways in which simple machines can be combined to create compound machines.

How much do you know about simple and compound machines? 

Can you identify the simple machines in these photos?
