IAL Biology Unit 6

Unit 6 Core Practicals

CORE PRACTICAL 10

Investigate the effects of light intensity , light wavelength , temperature and availability of carbon dioxide on the rate of photosynthesis using a suitable aquatic plant.

CORE PRACTICAL 11

Carry out a study of the ecology of a habitat, such as using quadrats and transects to determine the distribution and abundance of organisms, and measuring abiotic factors appropriate to the habitat.

CORE PRACTICAL 12

Investigate the effects of temperature on the development of organisms (such as seedling growth rate or brine shrimp hatch rates), taking into account the ethical use of organisms.

CORE PRACTICAL 13

Investigate the rate of growth of microorganisms in a liquid culture, taking into account the safe and ethical use of organisms.

CORE PRACTICAL 14

Investigate the effect of different antibiotics on bacteria.

CORE PRACTICAL 15

Use an artificial hydrogen carrier ( redox indicator ) to investigate respiration in yeast.

CORE PRACTICAL 16

Use a simple respirometer to determine the rate of respiration and RQ of a suitable material (such as germinating seeds or small invertebrates).

CORE PRACTICAL 17

Investigate the effects of exercise on tidal volume , breathing rate , respiratory minute ventilation , and oxygen consumption using data from spirometer traces.

CORE PRACTICAL 18

Investigate the production of amylase in germinating cereal grains.
