The explanation here is a bit tricky, since there are two effects: The smaller one is that the O2 gets burned to co2 and h2o, h2o condenses -> less pressure. The bigger effect is just that the air is hot and cools down quickly after the candle is off, causing the pressure to fall. (I think they told my son the first explanation.)<br />There is a website with science experiments for kids rigb.org/ExpeRimental I haven't done much, since my kids are only 3 and 5, but Ed Yong recommended it a while ago, so it kind of has to be good.<br />Keep us posted if you do more experiments!<br />IrisevelynAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-29235839.post-31136788304574239292014-11-07T22:57:16.788-08:002014-11-07T22:57:16.788-08:00I remember doing one when I was in 3rd or 4th grad...I remember doing one when I was in 3rd or 4th grade, using a thumb tac and a water bottle. If you stick the tack into the bottle and remove it creating a hole, no liquid will come out because of surface tension, and if you make a bigger hole it will come out.Juliahttp://www.ambitiousadventurers.comnoreply@blogger.comtag:blogger.com,1999:blog-29235839.post-26453537793319789052014-11-07T07:26:23.141-08:002014-11-07T07:26:23.141-08:00This reminds me of when my dad opened a big bottle...This reminds me of when my dad opened a big bottle of soda that had been in the garage when it was freezing outside. The soda was liquid when the bottle was sealed (i.e. pressurized), but froze instantly as soon as he opened it inside. He was surprised himself, until he wrote out the PV=nRT equation and we proved why it worked that way. The equation might be a bit much for your kids (I was in high school), but the 'experiment' is easy.

Are you on Instagram? There's a lady I follow who does really cute and easy crafts.... we follow and do the same but ours are MUCH less cute :)Marcia (123 blog)https://www.blogger.com/profile/15581613927187600748noreply@blogger.comtag:blogger.com,1999:blog-29235839.post-71741983820951888012014-11-06T05:15:22.797-08:002014-11-06T05:15:22.797-08:00Loved this post!

He would first have to guess which will dissolve and which won't.<br />Then the float-sink experiment. Ice floating really blew him. I started about densities, I guess it should wait!Layahttps://www.blogger.com/profile/06419743271832804741noreply@blogger.com
