Key Performance Indicators
Year 7 Milestones - Science
Biology
I can identify cells as the fundamental unit of living
organisms, including how to observe, interpret and record
cell structure using a light mircoscope.
I can explain the functions of the cell wall, cell membrane,
cytoplasm, nucleus, vacuole, mitochondria and chloroplasts.
Cells and organisation
Reproduction
(Including Plants)
Nutrition and Digestion
I can recognise the similarities and differences between
plant and animal cells.
I can identify the role of diffusion in the movement of
materials in and between cells.
I can explain the structural adaptations of some unicellular
organisms.
I can identify the hierarchical organisation of multicellular
organisms: from cells to tissues to organs to systems to
organisms.
I can identify reproduction in humans (as an example of a
mammal), including the structure and function of the male
and female reproductive systems.
I can explain the menstrual cycle (without details of
hormones), gametes, fertilisation, gestation and birth, to
include the effect of maternal lifestyle on the foetus through
the placenta.
I can identify reproduction in plants, including flower
structure, wind and insect pollination, fertilisation, seed and
fruit formation and dispersal.
I can investigate some dispersal mechanisms.
I can recognise the importance of plant reproduction
through insect pollination in human food security.
I can explain the content in a healthy human diet:
carbohydrates, fats, proteins, vitamins, minerals, dietary
fibre and water, and why each is needed.
I can identify simple food tests for starch, simple (reducing)
sugars, protein, fat.
I can explain calculations of energy requirements in a
healthy daily diet.
I can identify the consequences of imbalances in the diet,
including obesity, starvation and deficiency diseases.
I can identify the tissues and organs of the digestive system,
including adaptations to function and how the digestive
system digests food (enzymes simply as biological catalysts).
Nutrition and Digestion
I can recognise how the digestive system digests food
(enzymes simply as biological catalysts).
I can explain the importance of bacteria in the digestive
system.
I can recognise the impact of exercise, asthma and smoking
on the breathing system.
I can explain the structure and functions of the gas exchange
system in humans, including adaptations to function.
Respiration and Breathing
Systems
I can identify the mechanism of breathing to move air in and
out of the lungs, using a pressure model to explain the
movement of gases, including simple measurements of lung
volume.
Chemistry
Pure and
Impure Substance
I can explain the difference between a pure substance and
mixtures, including dissolving.
I can explain techniques for separating mixtures:
chromatography, filtering, evaporation and distillation.
I can identify pure substances and the concept of a pure
substance.
I can identify the principles underpinning the Mendeleev
Periodic Table.
I can recognise the Periodic Table: periods and groups;
metals and non-metals.
The Periodic Table
and Materials
I can recognise how patterns in reactions can be explained
and predicted with reference to the Periodic Table.
I can identify the varying physical and chemical properties of
different elements.
I can state the chemical properties of metals and non-metals
and metal and non-metal oxides with respect to acidity.
I can explain metal and non-metal oxides with respect to
acidity.
I can explain atoms and molecules as particles.
I can explain a simple (Dalton) atomic number and the
nature of atoms, elements and compounds.
Atoms, Elements
and Compounds
I can identify chemical symbols and formulae for elements
and compounds.
I can recognise conservation of mass in chemical and
physical change.
Physics
I can identify forces as pushes or pulls, arising from the
interaction between two objects.
I can use force arrows in diagrams, adding forces in one
dimension, balanced and unbalanced forces.
Forces and
Motion
I can explain moment as the turning effect of a force.
I can identify forces associated with deforming objects such
as stretching and squashing springs.
I can identify forces of friction between surfaces, resistance
to motion of air and water.
I can explain that forces are measured in newtons and
measurements of stretch or compression as a force is
changed.
I can recognise extension linear relation; Hooke’s Law as a
special case.
I can identify work done and energy changes on
deformation.
I can recognise non-contact forces such as gravity forces
acting at a distance on Earth and in space.
I can explain forces being needed to cause objects to stop or
start moving.
I can identify that forces change their speed or direction of
motion and change depends on direction of force and its
size.
I can identify frequencies of sound waves, measured in hertz
(Hz).
I can explain echoes, reflection and absorption of sound.
Sound Waves and Energy
Waves
I can recognise that sound needs a medium to travel, the
speed of sound in air, in water and solids.
I can identify that sound is produced by vibrations of objects
for example in loud speakers.
I can identify that sound is detected by their effects on
microphone diaphragm and the ear drum and that sound
waves are longitudinal.
I can recognise the auditory range of humans and animals.
I can recognise that pressure waves and transferring energy
are used for cleaning and physiotherapy by ultra - sound.
I can identify that waves transferring information are used
for conversion to electrical signals by microphone.
