Fieldwork is appropriately included in Unit 1 of the proposed study design whilst it was an appropriate inclusion in Unit 2 of the current study design. There is also provision in the proposed study design for reduction in the number of assessment tasks to be undertaken by students. Current Unit 1 assessment tasks Proposed Unit 1 assessment tasks Assessment tasks for this unit are: For Outcome 1: a student-designed and/or adapted and/or extended practical investigation; And For Outcomes 1 and 2: at least three from the following: practical activities or investigations multimedia presentation media response oral presentation annotated poster data analysis problem solving test, multiple choice and/or short answer and/or extended response.

Outcomes Outcome 1 Explain the dynamic chemical nature of the cell in terms of the key molecules involved in regulation, photosynthesis and cellular respiration, and analyse factors that affect the rate of biochemical reactions. Outcome 2 Apply a stimulus-response model to explain how cells communicate with each other, outline human responses to invading pathogens, distinguish between the different ways that immunity may be acquired, and discuss how malfunctions of the immune system cause disease.

The Outcome 3 task may be undertaken in Unit 3, Unit 4, or across Unit 3 and Unit 4, but will be reported as part of Unit 4 School-assessed Coursework.

Outcomes Outcome 1 Analyse evidence for evolutionary change, explain how relatedness between species is determined, and discuss the consequences of biological change in human evolution. Outcome 2 Describe and use tools and techniques to manipulate DNA, explain how biological knowledge is applied to biotechnical applications, and analyse interactions between scientific knowledge and its applications in society.
