Ant science fair project (Natalie, Chicago, USA)


Hi!

I am Natalie, I'm in 8th grade in chicago and i Am doing science fair, I am putting ibuprofen in ants food and drink. My question is: Will trace amounts of ibuprofen affect the behavioral patterns of red harvester ants? I have both on my ant farms set up, and 15 ants in each, I just would like some help along the way so i can do a great science fair!

Thanks and hope to hear from you soon.

Dear Natalie,

We are glad to hear that you are participating in a science fair and that you are planning to include ants in your experiment. Regarding the experiment you are planning to conduct, here are a few things to consider:

- How will you measure the behavioral patterns of the ants to see if they are different? There are many ways to do this, but you will want to come up with some way to standardize your measurements. Will it be how much food they consume and how will you determine this? How often the ants are active versus not moving for specific periods of time that you are watching them? How often do the ants engage in different behaviors between the treatments (grooming themselves, grooming other ants, etc.)? There are lots of observations you could make, just be sure to decide ahead of time what you will do. One idea might be to just spend some time watching your ants before starting the experiments to get ideas.
- To insure that you are measuring the effect of the ibuprofen, you will need to have a "control", which in your case would be a group of ants that you are not feeding ibuprofen, but otherwise are treated and fed exactly the same. This will allow you to determine if the ibuprofen is what is causing the differences.
- You would ideally also like to have multiple pairs of ants that are and are not fed ibuprofen (but I realize this may not be possible for your project this year).

We hope this helps and have fun watching your harvester ants! Harvester ants from the genus Pogonomyrmex are beautiful animals (to see what they look like up close click here).

Enjoy,
