Ok, cool! How is this a science fair project though? In ISEF, you need an independent variable, and a dependent variable, this way you can run experiments and test. How do you test this and get data from it?

In reply to Laurie Stacey. When you move the dowel in front, it gets closer to the taped down dowel in the back. This is like closing a pair of scissors. The whole tower gets taller and narrower.

Hi, I don’t understand the last step where you attach the syringe to the wooden dowel. How does that raise the elevator?

If you had the popsicle sticks pre-drilled, how long do you think it would take you to build on with kids?

The idea is very good, is there another example for biology. (form Indonesia)

In reply to Lauren. You could maybe try metal brads or twisty ties perhaps?

Hi, Karyn,
I was wondering if the wire is necessary to connect the popsicle sticks or if it could be substituted? I’m a librarian and sometimes I’m limited in what I can order and use so I’m trying to brainstorm how I could possibly alter this to do with my program kids. Many thanks!
