Introduction
Ant Facts
Materials and Methods
Predictions
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:Bridge Type Dimensions Materials Angles
Horizontal 2cm Foam Core 0
Vertical 2cm Foam Core 90
Long 2cm Foam Core 45
Short 2cm Foam Core 45
Wide 4cm Foam Core 45
Narrow 1mm Wire 45
Rough 2cm Cardboard 45
Smooth/Slippery 2cm Foam Board/ Plastic 45
Other Materials Standards Other Specifications
Sobo/ Tacky Glue Width: 2cm * Smooth Transitions from Ground to Bridges
Jelly & Sugar Material: Foam Core * Careful Craft
Fish Tank Angles: 45 * Maintain Standards when Possible
Hot Glue Glue: Sobo/ Tacky
Plexy glass

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.
