Earth systems unit gone
In the last version of Blueprint, we have removed the two key concepts that formed the Earth Systems unit in Year 8. These were: rock cycle and water cycle.
Why? First, the rock cycle is covered in KS3 geography, so it seems to be duplication to make it a key concept in science. Second, there is no mention of rocks in GCSE. The water cycle plays a very small role in biology at GCSE, with a limited amount of knowledge, so we reasoned that it does not deserve the status of a key concept.
