Success Criteria:• Draw a detailed diagram how my machine will make an egg move

(L4)• Label the direction of all the relevant forces acting on your machine

(come up with more than one idea)(L5)• Describe the forces that will make the egg move and slow down at

the end (L6)

(Challenge) Include materials used and how they will be strong enough.

Keywords: friction gravity thrustbalanced unbalanced

AnalysisHow could your machine be improved?(4)

What are the strengths of your machine? (5)

Considering other machines, describe how the machine could be improved compared to others (6)

Level 4 a describe where more than one force acts on

your machine b shown the force which will make the egg

move c made a machine from an initial plan which

will make an egg move

a shown some planning for the design of my machine b shown on a detailed diagram how my machine will make an egg move

Describe another example of a machine which uses a force to make something move.(4)

Level 5 To reach this level I could have: a labelled a diagram with the direction of all the

relevant forces acting on my machine b produced a diagram or description of the force

which is going to make my egg move c produced more than one initial plan; compare the

plans and chosen the best one, and made a machine from that plan to make an egg move

Idea 3 a shown detailed plans of more than one possible solution, with a drawing of my machine

b shown in detail which components will use forces to make my egg move, and describe how I have made them.

Describe how a number of different machines use forces to make things move

Level 6 To reach this level I could have:a label a diagram with all of the forces acting on my machine, and described what each force does.b Described the parts of the machine which will make the egg move, and which will make it slow down at the end.c carried out some research into potential designs of egg mover; considered each plan and choose and make the best model to make my egg move.


b show in detail which components will use forces to make my egg move, and describe how I have made them, including how I have made them strong enough

Describe in detail how a range of different sorts of machine use forces to make things move.
