Scalar quantities only have magnitude (size) and no direction, like time, energy, and length. Vector quantities have both magnitude and direction. Vectors can be represented by arrows. The length of the arrow represents the magnitude of the quantity and the head represents the direction. Velocity and forces are examples of vectors. In order to completely understand a force, you need to know both the size of the force, but also the direction the force is acting in.
In this activity, students will create a T Chart that identifies and illustrates scalar and vector quantities. Give students a list of quantities and have them sort them into either vector or scalar quantities, or let students choose the quantities themselves.To support students who need help, print out the example storyboard, cut it up, and have students put it back together as a card sort.
| Vector | Scalars |
|---|---|
| Thrust | Length |
| Displacement | Temperature |
| Weight | Voltage |
| Acceleration | Time |
| Momentum | Power |
| Drag | Area |
| Lift | Energy |
| Movement | Pressure |
| Velocity | Speed |
