DS - in Yr 8 - has to make a model of a river feature - an estuary, delta, waterfall, riverbed along those lines.

He wants to get some polystyrene and carve it to make a waterfall???? :roll: I don't have a clue of how to do this but am open to offers.

I was thinking about chicken wire covered in paper mache, painting river banks brown/green and river bed blue - he says it won't be good enough. Any advice, websites would be much appreciated.

Can feel my desert island coming on again (as in running away to find a desert island and relax!!) :lol:

I was just going to say that paper mache would be best and then you said it wouldn't! :? Polystyrene is a nightmare to work with and paper mache does look more natural.

How about a cross section through a waterfall, then you could show the rock stata - soft rock being eroded etc.
Polystyrene covered in paper mache should work, with the flat side / cross section in card / paper / photocopy from text book.
Have fun, amazing how these things come to light on a Sunday evening.

This kind of homework is so infuriating - why can't the teachers see what a ridiculous hassle it is for the parents who always end up doing it? I must say I haven't had to do anything like this since kiddywinks were at primary school - and even my pathetic practical skills were up to impersonating a 7 year old's.

I agree KES parent-we spent half term making a fantasy marine creature for art and a sperm cell model for Science-what was learnt was negligible,just caused expense at Hobbycraft! We are not one of those familes that have crafty stuff hanging around the house!

My son used a water pump (the small ones you can get for fish tanks), a plastic comtainer and a papermache/chickenwire rockface to make a model when he had a project on waterfalls in Y6. It was a right faff tho' as he used the wrong paint for the rocks and it took him ages to do.
His idea and he was determined to do it!!!!!!!

I'd go for a river myself.....you could still have water in a container but build up the river round it (your son could put the water in at the last moment....with rocks & sand in the water)

If he is desperate to do a waterfall (and you can disuade him from using real water) then I would use thin strips of clear, light blue, green plastic. when they catch the light they look like water.

I was relieved that the word "model" on the science sheet had got crossed out and "diagram substituted....... :wink: Fortunatley a surfeit of old preclinical medical textbooks were dug and vague memories of specialised cell types came to mind!
Think we were lucky and could choose any specialised cell type... try a red cell next time - few functions / throws out its nucleus and mitochondria early on in development and has a lovely squidgy shape
