To ask for your help with DS’s Science homework?

[KhalliWhalli]

So this is how the conversation went:

Me: Your science teacher said you haven’t done your homework.
DS: I tried, but it was just too hard.
Me: Rubbish. You’re just not trying hard enough. Give it here...
DS: OK Mum. You have a science degree. Please help me.
Me: Blimey, this is really hard, let me ask on Mumsnet...

So here we are asking for help. I don’t even understand the questions! Can someone help us? Thanks.

If he's struggling, he needs to talk to his science teacher. He needs to understand what he's being asked and how to answer. The internet won't be there when he's taking his exams

I think this is one of the most complicated things I’ve ever seen.
I’m 23 and failed both science and maths, though, so maybe that’s why. It just doesn’t make sense in my brain.

It seems a lot of people have helped you out here, OP - but YANBU to ask Mumsnet for help.
