This Force, Motion, & Energy science unit investigates contact and non-contact forces. Demonstrations and experimental procedures are explored with particular attention given to the scientific method.
It consists of 7 lessons of approximately 60 minutes duration.
The sequence of lessons and suggested time frames should be regarded as a guide only; teachers should pace lessons in accordance with the individual learning needs of their class.
A knowledge check for monitoring student understanding of the unit objectives is included and will require an additional lesson.
Teachers are encouraged to collect samples of students’ work throughout the unit to add to a learning portfolio. These can also be used to assess students’ understanding of the unit objectives.
This unit plan includes the following resources:
- Push It – Introducing the Different Types of Force PowerPoint
- Types of Contact Force Worksheet
- Force and Speed – The Relationship Between Force and the Resulting Speed of an Object PowerPoint
- Science Experiment – Speed Racer
- Electric Avenue – Understanding the Non-contact Force of Electrostatics PowerPoint
- Opposites Attract – Understanding the Non-contact Force of Magnetism PowerPoint
- Observing Magnetic Flux Lines Worksheet
- There’s a Fraction Too Much Friction – Science Experiment
- Throwing, Dropping, Bouncing, Rolling – Science Experiment
