KS4 Science:

Year 11:
In Year 11 the pupils will be undertake their second science GCSE.

Term 1:
• The chemical reactions essential for life take place inside cells.
• Respiring cells require a supply of glucose and oxygen, producing carbon dioxide as a waste product.
• Genes are the template for protein synthesis inside cells.
• The digestive, circulatory and respiratory systems provide cells with the basic materials they need to carry out their functions.

Divide and Develop
• Organisms grow by cell division, elongation and differentiation of cells.
• Plants and animals are different and this results in different patterns of growth and development.
• There is a variety of environmental factors that will influence the growth and distribution of plants.
• Human intervention can manipulate the outcome of reproduction.
Term 2:
Energy Flow:
• Plants provide energy for all other organisms.
• Plants and animals are interdependent due to their use and production of oxygen and carbon dioxide.
• Energy flows through the biosphere and elements are recycled within it.
• Human activities are often unsustainable and there are many associated ethical considerations.

Interdependence:
• Organisms compete with each other for resources.
• Organisms are interdependent which affects their distribution and population size.
• Organisms have evolved to survive in extreme environments.
• Human impacts on the environment and conservation measures need management.

GCSE modular Biology exams in November

Term 3:
Synthesis:
• Organic compounds contain the elements carbon and hydrogen and many originate from living things.
• Many new substances are made from oil.
• Polymers are large molecules which can be formed by the repeated joining of monomer molecules.
• Disposal of some polymers is an environmental problem.
• Raw materials are converted into new and useful substances by chemical reactions.
• The amount of reactant needed to form a desired quantity of product can be calculated, but the actual yield is lower than the theoretical yield and this has financial implications.

In Your Element
• The number of outer electrons in an element determines its position in the periodic table and its reactivity.
• The process of electrolysis.
• The existence of isotopes and their relationship to relative atomic mass.
• The importance of electrons in ionic and metallic bonding.

Term 4:
Chemical Structures
• Bonds result from the forces between the electrons and the nuclei of atoms.
• Atoms bond in different ways to form compounds.
• The structure and properties of substances are dependent on the nature of the bonding.

How Fast? How Furious?
• Different chemical reactions occur at different rates and these rates can be changed.
• Some reactions give out energy while others take in energy.
• Chemical reactions involve breaking bonds and forming bonds.
• Reactions are reversible.

GCSE Chemistry modular exams in March

Term 5:
As Fast as You Can!

Learning objectives
The motion of moving objects can be measured.
Forces can affect the motion of an object.
The speed of falling objects usually change as they fall.
Vehicles and theme park rides have safety features to protect passengers from injury.

Roller Coasters and Relativity:
• How theme park rides work.
• For an object to move in a circular path a force must act on it.
• Energy can be converted from one form into another but it cannot be made or destroyed.
• New scientific theories are not always derived through experimental methods.

Term 6:
Putting Radiation to Use:
• Atoms are made from particles that can be combined in different ways to produce isotopes, some of which are unstable.
• There are different types of ionising radiations that have different properties.
• The activity of a radioactive source can be measured and used in practical situations.
• Radioactivity has useful applications in everyday life and medicine.

Power of the atoms:
• Nuclear power stations use chain reactions to produce electricity.
• The Sun produces its energy using nuclear fusion.
• The movement of charged particles forms an electric current.
• Static charges have useful applications but they can also create hazards.
