jubygirl Posted August 9, 2011 Share Posted August 9, 2011 We are going to be studying Latin and Greek Roots this year. The first word we will be studying is "photos" meaning "light." One of our English words we derive from that Latin word is "phototropic" meaning "turning toward the light." I would like to do a little hands-on demonstration for my boys to fully understand what this word means. Does anyone have any step-by-step directions on how to show phototropism with a lima bean? :001_unsure: Thanks! Quote Link to comment Share on other sites More sharing options...

I wouldn't worry about the turny thing Edited August 9, 2011 by Sis Quote Link to comment Share on other sites More sharing options...
jubygirl Posted August 9, 2011 Author Share Posted August 9, 2011 I need something that talks to me like I'm a 1st grader. Do I soak the lima beans first? Do I simply plant them in a pot with potting soil and put them on the window sill? It's been a long time since I've done this experiment! I need a simple, straightforward approach. Thanks for that website though. If I don't get anymore responses, I just might adapt that one and wing it. :001_smile: Quote Link to comment Share on other sites More sharing options...
Slartibartfast Posted August 9, 2011 Share Posted August 9, 2011 I would soak them a bit and then stick them in some soil You could honestly just stick the plant in the window and it would work. You can look at the plant once it grows a bit and starts to "reach" then turn it and the plant will go the other direction. Quote Link to comment Share on other sites More sharing options...
