Controls are conducted with plain lanolin, untreated cut coleoptiles and intact coleoptiles One of them contains a plant Beneath the description of ggcse experiment you will find links from which you can open or download the experiments in Word format, and a link from which you can download the group of documents in a zip file.

The tubes are illuminated or darkened 8.

The fall in water level is measured coursewwork a measuring cylinder. Experimental work in biology: A control with plain lanolin is included Both are then placed in warm water and the sensations compared Slaked lime is added to a clay suspension.

These are then examined and counted under the microscope.

Water is poured through equal volumes of sand, clay mixtures in funnels and the volume passing through in a given time is measured. The volume of water passing through equal depths of topsoil of varying grades is measured. These experiments are available as a PDF booklet which can be opened or downloaded here: The levels of liquid in each tube are observed 6.

Nitrates are washed out of a soil sample and are shown to reappear after a few days, using diphenylamine sulphate as a nitrate indicator. The tubes are illuminated or darkened 7. The liquid which condenses is identified Water is poured through equal volumes of peat and sand.
