Ashley, your blog is showing no where as much work as it should. You've practically reached the end of the first term, and you've posted 3 posts, which would have taken less than 10 minutes each. This is definitely not good enough. This subject is 1/6th of the load of your maths. You need to ask yourself whether you are actually spending the required amount of time on this subject.
ReplyDeleteAlso, the experiments you have come up with are not scientific enough to complete as a long term experiment. You may be able to for some of them, but they definitely ALL need more planning and thought.
