Groups one and two are also compared to show differences in reactivity due to the position and arrangement of electrons. Students use a series of images to describe the journey of a hydrocarbon.

To be able to describe the role of enzymes in theOverview: The sheet includes additional, more complex calculations. Produce an annotated summary of the different groups in the periodic table with equations and trends.

A word bank is provided to help support and focus students, if required. The arrangement of electrons in atoms is identified and used to link this arrangement to the position of the element in the table.

Links between reactivity and uses of compounds. The uses of the different groups in the periodic table is considered, and the use of Guided Learning Hours word and symbol equations to explain reactions.

Students will then develop an understanding of the relationship between work done, energy transferred and power. The chemical inertness of the noble gases is considered, and the historical discovery that led to the formulation of a hypothesis about air.

This is then exemplified by considering the motion of an object as it falls through a vacuum and the atmosphere. Here the use of scientific models to demonstrate phenomenon can be utilized.

Bring further students to the front of the class until you have a molecule of poly ethene. Students use this context to study the role of the wider scientific community in validating theories. Debating the benefits and drawbacks of scientific developments including those linked to environment,Systematic sampling, health and quality of life — importance of respiration, effects of exercise, factors affecting photosynthesis.

This could be easily adapted for alkenes. The link up the monomers. Elements are classified as metals or non metals, and the terms atomic number, massOverview: Guided Learning Hours Approximately 13 hours including one hour for revision and test. There is no practice controlled assessment for this unit.

Building a sense of order and predictability in the world by understanding the principles of how things work SMSC — understanding aerobic and anaerobic respiration, effects of exercise, sampling techniques, limiting factors for photosynthesis.

Where we come from? How scientific knowledge changes over time. To discuss the theory of evolution and fossils as evidence.NUCLEAR REACTIONS.

After reading this section you will be able to do the following: Describe an atom using its chemical notation. Begin to understand nuclear reaction equations.
