Osmosis starter task (GCSE Biology)

A worksheet aimed at GCSE (14-16 year old) students, this resource is ideal as a starter activity following a lesson on the principles of osmosis. The worksheet includes several questions that probe understanding of what osmosis is, how we can use knowledge of osmosis to predict water movement into and out of cells and finally a challenge question on how salt can be used to kill slugs by dessicating them.
