Tuesday 4th November PM 2014 60mins
Cells, Organs & Genes
I know the basic structure, function and adaptations of the following specialised animal and plant cells:
neurones, red blood cells, white blood cells, egg cells, sperm cells, root hair cells, xylem and
phloem cells and guard cells.
I know the function of the components of cells: nucleus, cell membrane, cytoplasm, mitochondria and
the cell wall, vacuole and chloroplasts in plant cells.
I know that cells make up tissues, tissues make up organs and organs make up organ systems and I
can provide examples
I know different plant tissues (xylem, phloem, mesophyll) and plant organs (roots, leaf, stem) and can
describe the function of plant organs
I know what transpiration is and can name 3 factors which affect the rate
I know that DNA is a double helix and which base pairs always bond together
I know that DNA is split into sections called genes and that strands of DNA are called chromosomes
I know that alleles are different versions of the same gene and that the alleles an organism has make
them either homozygous or heterozygous and I know that heterozygous individuals can be carriers for
genetically inherited diseases caused by a recessive allele.
I can explain inheritance using Punnett squares and I can complete pedigree analysis for both
homozygous and heterozygous individuals. From these, I can determine phenotype and genotype
I can calculate the likelihood of an offspring displaying a particular characteristic from genetic crosses
I know how genetic mutations are caused, what happens to the organism if a mutation does occur and
that these can either be beneficial or harmful to the organism.
Nervous and Endocrine Systems
I know what homeostasis is and how it is controlled
I know that the nervous system is made up of the peripheral nervous system and the central nervous
system and I know the structures involved in each of them.
I know how impulses travel along neurones and the three stages of a nervous response
I know the difference between voluntary and involuntary responses and I know what a reflex action is
and I can describe the different parts of a reflex arc
I know that the endocrine system contains glands which produce hormones and I know how hormones
are transported around the body
I know the difference between nervous and hormonal response speed, method, duration and target area
I know how blood glucose levels are maintained by hormones and which hormones are used to raise or
lower blood glucose concentration
I know how the body raises or lowers the its temperature
Atomic Structure and the Periodic Table
I can use an element’s position on the periodic table to tell me which are metals and which are non-metals
I know the structure of an atom and the three sub-atomic particles, their location in an atom, their charge
and their mass
I know the definition of atomic number, mass number and relative atomic mass and I know where the
atomic number and mass number of an element is shown on a periodic table. I can also use this
information to calculate the number of protons, neutrons or electrons an element has
I know how elements are arranged in the periodic table and that they are grouped in periods (horizontal)
and groups (vertical) and I know the characteristics of elements in a particular group
I know what an isotope is and because of isotopes, relative atomic masses are not always whole numbers
and I can calculate the relative atomic mass of an element using the relative masses and abundances of
the isotopes
I know how electron shells are filled and know how to write the electronic configuration for one of the
first 20 elements.
Substances and Chemical Reactions
I know the difference between compounds, elements, molecules and mixtures
I can write word equations and simple balanced chemical equations and name the compounds
I know what an acid, base, salt, alkali and solution is (and I know what the difference between an alkali
and a base is) and I know that these can be produced when chemicals react together
I know what is formed when an acid and a base react together and when an acid and a metal react
together and when an acid and a carbonate react together
I know the tests for hydrogen and carbon dioxide and I know how to find out the pH of a solution using
litmus paper and Universal Indicator
I can identify hazard symbols
I know that neutralisation reactions are used for indigestion medicine and to neutralise soil
I can use the periodic table to recognise elements and chemical formulae and I can work out how many
atoms of an element are in a simple chemical formula e.g. HCl contains one hydrogen and one chlorine
atom
Energy stores, transfers and transformations
I know the six forms of energy and what they are used for
I know what chemical, kinetic, gravitational potential, elastic potential, thermal and nuclear energy stores
are and what they are used for
I know that energy can be transferred mechanically (when a force is applied to an object), electrically, by
conduction, convection or radiation.
I know that energy cannot be created or destroyed, only transferred and I know what unit energy is
measured in
I know the definition of power, what unit power is measured in and I can use energy transfer equations to
calculate power
I can use Sankey diagrams to work out how much useful or wasted energy a device produces
I can use the equation for working out the cost of electricity and equation to work out the efficiency of a
device
I know at least five renewable energy sources and the advantages and disadvantages of each of them
I can give an example of a non-renewable energy source and advantages and disadvantages of it
I know how small amounts of energy can be stored
Properties and Applications of Waves
I know some characteristics of waves and some examples of transverse and longitudinal waves
I know what wavelength, frequency, amplitude and wave speed are and I can label the wavelength and
amplitude on a diagram
I can use the wave equation to calculate the wave speed or frequency or wavelength
I know the seven different groups of waves in the electromagnetic spectrum, I know that they are
grouped by wavelength and I know which have the shortest wavelength and which have the longest.
I can give two examples of uses for each of the groups of waves
I know the dangers of microwaves, infrared, ultraviolet, x-rays and gamma rays
