Objectives |
Section 1: a. How fast is it moving?
Children should learn:
- that speed can be determined by measuring distance travelled and time taken
- the units in which speed is measured
- to manipulate and apply the quantitative relationship linking distance, time and speed
View related activities and outcomes
Section 2: b. How fast is it moving?
Children should learn:
- to plan and organise a group activity to solve a problem
- to make sufficient measurements using ICT
- to use ICT-generated graphs
- to describe trends or relationships in graphs
View related activities and outcomes
Section 3: c. How fast is it moving?
Children should learn:
- to compare and evaluate different ways of making measurements
- that measurements for different purposes may not be equally precise

Section 4: How do forces affect speed?
Children should learn:
- that a force produces a change in speed (an acceleration)
- that in the absence of force, objects move at a steady speed, or remain stationary
- to make generalisations about forces and speed

Section 5: Checking progress
Children should learn:
- about the forces on moving objects
- that objects can continue at steady speeds with no force acting in the direction of movement

Section 6: a. How can we increase speed?
Children should learn:
- that air resistance and water resistance are forces that oppose motion
- how the effects of air resistance and water resistance can be reduced by streamlining
View related activities and outcomes
Section 7: b. How can we increase speed?
Children should learn:
- that air and water resistance increase with increasing speed
- that the energy required to keep a moving object moving depends on air resistance
View related activities and outcomes
Section 8: c. How can we increase speed?
Children should learn:
- to apply knowledge of the particle model in explaining air resistance
View related activities and outcomes
Section 9: How do parachutes work?
Children should learn:
- that when the upward force of air resistance balances the downward force of weight, the speed remains constant
- to interpret distance-time graphs and relate them to the situation from which data was obtained
- to translate data presented in one form into another

Section 10: Reviewing work
Children should learn:
- to use understanding to evaluate a device or contribution of a scientist/inventor
