Forces and Movement

Good morning Miss Battista's grade 3 class! 

As you know, there are two basic types of forces that cause movement. As we have seen in class, contact forces involve direct interaction (pushes and pulls between surfaces that are in direct contact). Non-contact forces include magnetic and gravitational forces and involve interaction at a distance. As a class, we have explored the effects of forces from sharing our "invention designs", and we have also seen ways in which forces, including forces in nature, cause objects to move. 

Watch this video clip from Bill Nye the Science Guy as he explains forces of movement. This may help you have a better understanding of what we have been learning in class.

Parents:

The students have been learning about various types of forces and movement within the environment. The students were given a task in groups in which they had to design and build their own machine that would be fully functional in moving objects. This unit is in line with the Ontario curriculum standards under the science and technology strand fro grade 3. It states that:

       - 2.2. Students will investigate forces that cause an object to start moving, stop moving, or change        

         direction

       - 3.1. Students will identify a force as a push or a pull that causes an object to move
