Frequently Asked Questions:

1. How do I sign up as a Citizen Scientist? Do I have to donate?

Everyone who donates $25 will get to be one of our Citizen Scientists. Donations of more than $25 will help pay for kids and schools to participate. If you want to be considered for a free kit, sign up to be added to our waiting list.

2. Why can't I just get my own corn to do the experiment?

There are good scientific reasons why we are providing the corn for this experiment. First, this GMO and non-GMO corn are from very similar varieties. That way, we know the main difference between them is the genetically engineered traits, not other traits like taste or color. Usually, scientists use nearly identical varieties called "isolines" to make sure no other genetic differences could explain the outcome of their experiment. Since the original reports of feeding preference involved commercial hybrids, we chose to use similar commercial hybrids to closely mimic the original experimental conditions. Second, these ears were grown in side-by-side plots, meaning that the growing environment was nearly identical. (The plots were separated to limit cross-pollination between the two different varieties.) Third, all of our Citizen Scientists are repeating the same experiment with the exact same varieties of corn, so we can combine the results together. If we find a difference between GMO and non-GMO corn, we can rule out other genetic or environmental factors as possible causes. Lastly, the corn was donated by Monsanto, at our request, so we could do the experiment with the latest varieties. We did all the legwork to get a signed “Material Transfer Agreement” that allows us to publish the results.





3. Is it safe for animals (and people) to do this experiment?

Yes! This corn we was grown for the purpose of being eaten, and the genetically engineered traits have been approved by the FDA, EPA, and USDA. There's nothing experimental about these varieties, which are grown by farmers every year. Feeding squirrels corn in your backyard is a common practice, and is even suggested by the Humane Society as a way to keep them away from your bird feeders! There will be no touching or handling of wild animals in this experiment, the corn is just being left out for them to nibble on and our volunteers will take pictures of the results.

4. How will I know which ears are GMO and non-GMO?

The ears in each experiment kit are labeled with a number, but the labels do not say which ears are GMO. Why? This is called "blinding" and is an important part of the experiment. This keeps Citizen Scientists from accidentally (or purposefully) altering the results. We will keep track of the labels and will tell you which ears were which once the experiment is complete. In addition, this information will be posted online in a password-protected file before the experiment, and we will publish the password when the experiment is done. That way everyone can verify that the results are true. Think of it like a surprise waiting for you after you finish your experiment!







5. I do not live in the United States - will I be able to participate?

Every country has different laws regarding the approval of genetically engineered crops, and the movement of seeds in and out of the country. A lot of this is for very good reasons such as preventing the movement of plant pests and diseases around the world. The corn we are using in this experiment was grown in the United States, and contains traits that are approved for the United States. Currently, we are only offering to ship the experiment kits to addresses in the United States, but we are currently working on making it possible to ship them to Canada as well. We will make an announcement when and if we are able to include our northerly neighbor in this important experiment!

6. Can my child do this for their science fair project?

Yes, we totally encourage your child doing a science fair project around this! We are asking our volunteers to agree not to share their results publicly until we have a chance to analyze all the data and prepare it for publication. In fact, for students who want to go the extra mile with their experiment, we will provide guidance on how to record extra data that will make it more useful for a science fair project. Then, once the big paper with everyone's name on it gets published, everyone can unleash their projects on the world in unison!
