3. Objectives
- discover how objects move through interaction with
‘WeDo 2.0’ robot
- explore the effect of friction on movement through
experimenting with the robot on different surfaces
- investigate the idea of force through the use of the
robot and various different weights
6. Connect
What is a force?
What things do we push or pull on a daily basis?
Importance of force
Tug-o-war activity
Change the amount of children on each side of the rope to find equal
force
Look at friction – take off shoes
What effect does friction have?
7. Construct
Children building their model
Questions :
How does the model work?
How does the model move?
How could we use this model to test force?
What could you add to make the model better/stronger?
How could we make the model move for longer?
8. Contemplate
What weight is needed to balance the pulling force?
How do you know when the force is balanced?
What factors could you change in order to
increase/decrease the pulling force?
Emphasise fair test!
The children will then investigate the machine pulling the
weight on different surfaces
9. Analysing
What surface will the machine pull the most weight on?
What is the maximum weight the machine can pull?
Why is x the best surface?
From your results what can you conclude about the effect of friction
on force?
The children will present their fair test to the class in the form of a
group presentation using recording sheets and images.
11. Integration
Science – Scientific method: conducting a fair
test.
Literacy – Oral language development (tier 3),
engagement with procedural writing.
Maths – Problem solving, analytical skills.
12. Assessment
Formative : teacher observation (note taking),
conferencing with the children throughout the
lesson, thumbs, traffic lights
Summative: self assessment e.g what would you
do differently if you had to do it again?, group
presentation
