HelpingTeens: Support Groups

i know this is the wrong forum, but i want people to see this.



Anyways I'm in a group project, it's the final thing for Bio11 (frigg tori's in the group i know), but anyways my part is the circulatory system.



Basically i need a heart, and tubes/veiney things.



Any ideas what i could use as a heart and as the tube things?



thanks so much

For a heart you can use a balloon or just playdoh. For the tubes/veins just use straws or colored yarn.





do you have to make it actually work? or is it just a model?

like..just a shitty model.

and thanks!

For a heart you could use one of those little squeezy thinks that look like a ball and when you squeeze it air comes out of a little hole. Kinda like the ball thats on one of those little bicycle horns.
