Annie-pops Posted January 13, 2011 Share Posted January 13, 2011 Hi all, am just wondering whether all you clever people have any really good ideas for science investigation/ experiments that are fun and safe for 2 and 3 year olds. Am sure have seen a 'volcano' made with bicarbonate of soda and vinegar which would like to try next week and it's has got me thinking am sure there must be other simple kitchen cupboard science activities. ( Reason I am thinking along these lines is becauseI have been planning for a child who was really into rockets and thought the volcano might be an additional thing of interest as it has a propulsion/gases feel .... plus it's explosive and messy which is always a good thing! Any ideas gratefully received! x Link to comment Share on other sites More sharing options...

Any ideas gratefully received! x Bottles of good lemonade (really fizzy) drop in a few raisins and watch what happens! The bubbles in the lemonade attach themselves to the raisins and gradually the raisin lifts and rises to the top whereupon the bubbles burst and send the raisins back down again, only for it all to happen all over again.

Annie-pops Posted January 13, 2011 Author Share Posted January 13, 2011 Thanks Panders, that's just the sort of thing I'm looking for x Link to comment Share on other sites More sharing options...
Panders Posted January 13, 2011 Share Posted January 13, 2011 Just googled - have a look here http://chemistry.about.com/od/foodcookingc...experiments.htm 1 Link to comment Share on other sites More sharing options...
Annie-pops Posted January 13, 2011 Author Share Posted January 13, 2011 Wow - that's fab, am going to plan my Science Lab! Am particularly intrigued by the " breathing fire " window - I think that may be a 'risky play' challenge too far tho lol Link to comment Share on other sites More sharing options...
Inge Posted January 13, 2011 Share Posted January 13, 2011 try lime or lemon juice instead of the vinegar in the volcano.. a much better smell... or try both and see which smell they prefer.. 1 Link to comment Share on other sites More sharing options...
emz321 Posted January 13, 2011 Share Posted January 13, 2011 balloon rockets - blow up a balloon insead of tieing the end fasten it with a peg/clip so doean't deflate, attach a straw to the top with tap, thread a piece of string through the straw, attatch the lengh of string between 2 chairs, take the peg off the balloon and wath it fly along the string. When doing the volcaneo you can also use to make bubbling potions, just add glitter, washing up liquid clear vindear and bicarb of soda and watch the potion bubble over the side of the conatiner. also drop a packet of mints all at once into a bottle of coke and it will shoot into the air put a crisp packet in the microwave and watch it shrink! trying to think of things that we did in our science week but mind a bit dead at the moment, will write more when remeber!

Cait Posted January 13, 2011 Share Posted January 13, 2011 Give them all a chocolate button each to hold in their hand whilst you read Michael Rosen's poem, 'Chocolate' Look at me, look at me I've got chocolate It's the end of the party they've given me chocolate Look at me, look at me I've got chocolate I must keep my chocolate where no one can get it where shall I put it? in my bag? in my pocket? No. In my hand. I'll keep it Look at me, look at me I've got chocolate and I'm going home to eat it And we walk down the street it's a sunny day and hot for me and my chocolate and I've got it I've got it my fingers are round it tightly closed around it Look at me, look at me I've got chocolate And we get to my house and I rush in and shout Look at me, look at me I've got chocolate Let's see Let's see your lovely chocolate... and I open up my hands to show them the chocolate... ...and oh no! What do you know! That lovely big bit of beautiful chocolate has gone all soggy mucky and sticky like a handful of mud is all I've got is a big sticky mess oh no oh yes! Look at you Look at you what are you going to do? And I stop and I think and I think and I stop What's in my hand? What have I really got? Is it still chocolate? Is this mess chocolate or not? I know what I'll just try a little taste I take my tongue to my finger and my finger to my tongue and YUM! Look at me Look at me lick lick lick chocolate lick lick it lick it lick it lick it sticky sticky chocolate lick it lick it 'till there's nothing left not one little bit I've eaten my chocolate Look at me 1 Link to comment Share on other sites More sharing options...
Annie-pops Posted January 13, 2011 Author Share Posted January 13, 2011 Some brilliant ideas, many thanks. Found this and like the idea of the magic inflating balloon! http://www.sciencemuseum.org.uk/pdfs/outre...henScience1.pdf Link to comment Share on other sites More sharing options...
Jo A Posted January 14, 2011 Share Posted January 14, 2011 Also put milk on a plate and then some drops of food colouring then put some drops of washing up liquid and watch the patterns it makes Dissolve some salt in water and then leave until the water has evaporated away and see what is left What about making discovery bottles.

Annie-pops Posted January 14, 2011 Author Share Posted January 14, 2011 Thanks Jo x Also some good ideas here http://kitchenpantryscientist.com/ and there are also video clips showing her carrying out some of the experiments. She makes cornflour gloop and explains how it behaves how it does because depending how you handle it, the molecules are either long and stretch past each other or - when you roll it - become tangled. Now I knew what gloop did but not why! I have learnt something today! Link to comment Share on other sites More sharing options...

Harmony1985 Posted April 27, 2014 Share Posted April 27, 2014 Alka seltzer rockets. You'll need a camera film canister (I know who uses film anymore?!), water and alka seltzer. Put water and half a alka seltzer in the canister and very quickly put the lid on and turn it over. Move back and wait as the pressure builds up and up it flies!

Move back and wait as the pressure builds up and up it flies! you can also do this using paint in the cannister and launch from a large piece of paper to create explosive art!

Sue R Posted April 28, 2014 Share Posted April 28, 2014 If you search on this site you will probably find instructions for the volcano as well as lots of other science based ideas as this comes up regularly Sue Link to comment Share on other sites More sharing options...
