Er? Odd!!!
Cancel that last bit. My posts have suddenly re-appeared! (Although you're still welcome to e-mail me if you want to!)
To continue where I left off:
By now, you should be getting ready to wind up. Return to that question of cost.
"Who can remember? How much did we say it cost every time a lorry drops its load into a landfill site?". "
OK, so it costs your parents money if we don't recycle. It will cost you money, in the future, if you don't recycle. And there are massive costs to the planet, as well, if we fail to recycle. So what does it cost just to put our rubbish in the right bin?"
"Yes, that's it. Nothing. OK, perhaps a small amount of our time but, otherwise, nothing. Recycling helps the planet. Recycling is easy. Recycling takes hardly any time. Recycling won't cost you anything - In fact,when you're older it will save you money on your council Tax. But it's not something I just want you to do when you're older, it's something I think you should all be doing NOW. And don't just do it yourself, nag others to do it. Nag your parents if they don't recycle things. Look around this school and nag your teachers if you see things which ought to be recycled but aren't. But, at the end of the day, remember that recycling isn't just something to talk about, it's something to DO".
OK, my teaching style is probably different to yours. I wouldn't expect you to follow this like a script but I hope that it might suggest a suitable approach for your presentation.
