Rat Race Lab

Procedure:

Step 1: Gather all materials and set up experiment.

Materials:

• Robotic Bug
• Cardboard box
• Checkerboard grid paper
• Video recorder

Tape all checkerboard grids to the bottom of the cardboard box. Set the bug inside the box in any position and turn it on. Take a video of the bug moving

Step 2: Upload the video to Tracker and split it into enough frames for your data.

Step 3: Gather data from each frame. Find the horizontal and vertical position and record them.

Step 4: Find the distance and displacement of the horizontal and vertical positions.

Step 5: Record all data on spreadsheet and write lab report.

Conclusions:

What I Learned:

•  I learned about finding and using certain formulas for different movements of the bug throughout the lab.
• I learned how to use Tracker program and how it makes it easier to capture frames of ONE movement to find the data.
• I learned how to find the data for horizontal and vertical positions. (It's difficult!)
• I understand distance and displacement better.

Errors in Lab:

• The positions of bugs could have been a tad off.
• The formulas could have been off.
• On Spreadsheet, the formulas messed up for displacement.
