Step One: Do Ants Like Jelly?

Yes They Do!

Initial Designing Process We began with sketching different Bridge Designs…

First Bridge Model After It was destroyed by the weather.

Second Bridge Design This is the one we choose to go with because it worked the best.

Bridge Specifications:

Time Line (Revised)

Data Collection Sheet:

Continuous Student Observations:

Class Involvement Each student must check the ants (both indoor and outdoor) and fill out the student data sheet. Between now and Thursday morning have at least one observation from both indoor and outdoor. Be prepared to discuss your observations, compile class results, and analyze them.

Information and Steps for Student Observations Indoor ants are located in the lab with Thelma. Outdoor ants are located behind McKee. The data sheets are located with the bridges. When observing the ants take notice of how the ants are interacting with the bridges and the amount of food left (suggestion: take notes). PLEASE COVER THE BRIDGES WHEN FINISHED!!!!! If any questions arise please come and get us.
