Development of Target LT-F3.3
LT-F3.3	Describe what is meant by an abiotic factor and give some examples of how these can be measured
State that an abiotic factor is a physical factor affecting the distribution of living things.
Describe how the following abiotic factors may be measured :-	temperature dissolved oxygen light intensity humidity.
Explain the effect of two abiotic factors on the distribution of living organisms.

1	Use dataloggers to collect and analyse data from two different habitats, e.g. temperature, dissolved oxygen, light intensity, humidity over a 24 hour period. Secondary sources such as Ceefax, the Web and weather station reports may be used to confirm findings.
2	Design and carry out an investigation into effect of light, temperature, moisture on activity of woodlice, maggots, brine shrimps or water fleas.
