It is intended for all science teachers but particularly those who are not physics specialists. It is, primarily, aimed at 14 to 16 year old pupils but can also be used at a higher level as a precursor to a more in-depth study of this topic. Normally, the activities would fill a 45 to 60 minute lesson.

Learning Outcomes
The learning outcomes are based on Bloom’s taxonomy of hierarchical classification: knowledge, comprehension, application, analysis, synthesis and evaluation. The lesson title and learning outcomes are:

Can an object move if the forces acting on it are balanced?
Learning Outcomes
Knowledge

• to to identify the forces acting on a moving object
• to describe the effect of balanced and unbalanced forces on moving and stationary objects
  Analysis
• To calculate the size and direction of a resultant force

Differentiation
The activities have varying degrees of differentiation; please refer to the Readme document.
