Example set of combined science practicals 03 April 2017

Combined Science (Gateway Science J250 and Twenty First Century Science J260)

To exemplify how the requirements of the minimum numbers of practical activities and coverage of required apparatus and techniques can be achieved, we have compiled below a suggested list of activities. These activities have been mapped into a copy our (optional) Practical Activity Tracker to show how the requirements are covered. There are also links below to the activity documents and the (optional) Learner Record Sheets.

PAG B1 – Microscopy	Suggested Activity 1: Examining human cheek cells
PAG B2 – Sampling techniques	Suggested Activity 2: Investigating the differences in habitats using ecological sampling techniques
PAG B3 – Rates of enzyme-controlled reactions	Suggested Activity 1: The effect of substrate concentration on catalase
PAG B4 – Photosynthesis	Suggested Activity 1: Investigating the factors that can affect the rate of photosynthesis
PAG B4 – Photosynthesis	Suggested Activity 2: Investigating factors that affect the rate of water uptake in plants
