Draw a diagram of cells seen down a microscope

I know how to prepare a microscope slide to look at cells

Label the structures in all cells: nucleus, cytoplasm, cell membrane, mitochondria

Label the structures in a plant cell: all of the above, plus cell wall, chloroplast, vacuole

I know the role of the major organs

I know the organs found in each of systems: circulatory, respiratory,
digestive and nervous

I know the differences between a plant cell and an animal cell

I know the role of each structure in an animal cell

I know the role of each structure in a plant cell

Explain what a tissue is and give examples

Explain what an organ is and give examples

Explain how a cell is adapted to its role:

· Sperm cell

· Egg cell

· Red blood cell

· Nerve cell

I know what stem cells are

Explain how some of the problems caused by organ damage have been overcome using technology

Forces

Measure the size of a force and use the right units

Identify some different forces and describe how forces change movement

Describe how forces change an object’s shape, speed or direction

Understand that friction is a force that opposes movement

Understand that upthrust pushes upwards and weight pulls downwards

Compare the speeds of different things and give some examples of streamlined objects

Know what can increase friction, air resistance and water resistance

Identify the forces acting on an object and say which direction they are acting in

Describe situations where forces are balanced or unbalanced

Know that if the forces on an object are unbalanced, it will either change shape or speed

Draw and use force diagrams with arrows to show the direction a force is acting in

Describe places where friction is useful and some ways of reducing it where it resists motion

Understand that air resistance is the force of friction of air on objects moving through it

Describe how streamlining reduces air and water resistance

Understand that if an object’s speed changes then the forces acting on it must be unbalanced

That if the forces on an object are balanced then it moves at a constant speed

Describe how air and water resistance change with speed and begin to link these ideas to the particle model

Understand about the forces on falling objects

Use the particle model to explain scientifically why air and water resistance increase with speed

Explain the relationship between the forces on a falling object

Explain how unbalanced forces cause an object to accelerate
