Week+5

Week 5:

Hey guys, I know this week of science is going to be busy with presenting and finishing off posters..but i found a couple of quick experiments that might be good to finish with! I thought the kids could make slime! its really easy and cheap to make and kids love slime! the other thing i was thinking was something to do with eggs...last week they were asking if boiling an egg would be a chemical change and it is as the proteins in the egg cannot be returned to their original state once heated or mixed. still searching for a fun experiment on this but i mean how exciting can boiling eggs be? lol. What do you think? will we have time for one last experiment?

STEPH: Will we have time? Maybe if we get the kids to finish their posters and put their presentations together (who is saying what etc) then they can present. Then if we have time after that do an experiment?

yeh i think we will have time most of them are well on their way with the posters anard aka chess and scrabble champ have finished lol...its really quick and easy can do in ten minutes! they will love it!

hey guys ive put in the link for slime and pasted the ingredients in. does anyone have any of the ingredients at home? ill pick up cups and sticks and glitter and food dye. we probs dont need a dripper we can jus pour. so if anyone has borax or gladwrap let me no otherwise ill pick some up.

it should only take 5-10 minutes if need be!
 * 1 plastic disposable cup containing 20 ml of borax solution* (borax – or hydrated sodium borate– can be bought as powder from chemists/supermarkets, it is a cleaning agent)
 * 1 plastic disposable cup containing 20 ml of PVA glue solution*
 * 1 wooden lolly stick for stirring
 * 1 plastic dropper for the borax solution
 * food colouring/glitter - optional
 * clingfilm to wrap slime to take it home

Girls i think this is great! They will love having an experiment to finish on and they will always look at their slime and think of us -how sweet. Are their posters to be taken home? I was thinking it would be great for them to show their parents.. but as they are working in groups who will get to take it home? Problem! Maybe we should just leave them with the student and they can decide.

I can get the eyedropper things.
