Science with Year 10 Pathway 1 Group





Year 11 Practical Assignment - Parachute Investigation. Science coursework carries an important 20% of the final mark in this Double Award subject. Coursework can make the difference between a poor and a good pass mark. In these photographs Year 11 students are investigating the rate at which parachutes fall when variables such as canopy area, shape and mass of object are changed.


Year 10 are seen hear investigating the movement of liquids through a plant's stem. Food colour has been added to the water in each test tube to 'track' the movement of water during transpiration.

	The Team! On a very cold and windy day in March the Year 10 Pathway 1 Science Group took to a deserted Blackpool sea front to investigate corrosion!

Galvanized rails coated in Zinc provided great protection for the steel rails.	Strong evidence of the lack of protection given by simple painting seen hear.	Galvanizing provided better protection but still failed when zinc had been lost.	Stainless steel should have been able to survive due to the chromium in it.	Severer rusting at the base of this equipment could shorten its useful life.

	The Team! Our investigations continue below!


Troy in front of a sculpture which uses corrosion for artistic effect. I'm sure some people like it but no us!	Nathan under South Pier, the Victorians really knew how to 'over engineered' to account for corrosion.	Rust everywhere you look. The salty moist air is ideal for corrosion. Iron, even when painted is always under attack!	The struts and girders under the pier are not protected and have badly corroded. Only their size has saved them!	Rust, rust and more rust!!!! Iron Oxide has no strength and the pier has to be constantly repaired and maintained.

		Rusting: Iron Oxide can be prevented by keeping water and air away from iron. Both air and water are needed for rusting to occur!
	Metals are important to humans - we use them more and more - but corrosion has to be kept in check!
