Scientific Celery (gotta do something with it, no one will eat it)

Last Sunday night I started a science project for my girls.  I knew it would take a day or two to really show up, especially with wilty looking celery, so I best get it started before time to talk about what was happening.  Unfortunately the week got away from me.  We did talk briefly about what was going on, but mostly it was “wow that looks cool” and off they went.

 
I can’t seem to find the science project book I have that had this experiment in it, so I went online and found these fun sites:
 
  • Science Fair Adventure – they have detailed times to check the celery and report the new changes!
  • A to Z’s Home’s Cool Homeschooling – didn’t see this project but they had tons more, even for higher grades, some with wonderful YouTube videos!
  • The Homeschool Den – this family impressed me!  They did a whole month of science experiments!  What a way to survive a dreary January when everyone is stir crazy and tired of book work! **totally stealing this idea**

Let us know what your newest, craziest, or messiest science project has been this year!  Leave us a link! (I’m always on the lookout for new ideas)

Lesson in States of Matter, with snacks!

Let me confess, up front, that I walked in on a PBS show where the classroom was doing this and I thought it was a great idea! I’m trying to give credit where it’s due, but I don’t know which show they were watching (probably Sid the Science Kid).

The teacher filled a small shoe box tub with water, about 1/2 full or so, and froze it.  Then she layed in a layer of lemons, grapes, etc. and added some more water and froze that.  Looked like she may have done even another layer of water after that.  I’m thinking I’ll do a small block then set it inside a bigger one and so on so my layers are all around.

Then they flipped the ice block out and put it onto a deep tray (hmm.. roasting pan maybe?).  The kids took turns touching the ice, drawing pictures of the ice with the fruit ‘floating’ in it.  As they did work, and talked about ice, it started to melt.  After a while the kids could pick off the ‘snacks’, and the conversation moved to discussing the liquid state.

With it being so cold outside and everything so frozen I think this might be a fun activity for my girls to do.  We might even break out a hair dryer to speed it up a little.  Doodlebug is old enough to boil water, maybe we’ll take the melted liquid and move it to a pan where she can watch it become vapor.

ohh the ideas!

Here’s a cool site (FREE) that I found on states of matter… called Chem4Kids.com!
