7. The Plant the Moon Challenge

A project challenge at the intersection of biology and space, where students try to grow plants in simulated lunar or space conditions and learn the real problems of growing food off Earth.

  • Eligibility: Middle and high school students interested in space and biology.
  • Award: Certificates for all participants, with standout projects earning recognition, prizes, and invitations to workshops and webinars.

8. BioGENEius Challenge

A biotechnology competition recognizing high school research in the life sciences, where students present their work to scientists and industry professionals. (Here’s our BioGENEius guide.)

  • Eligibility: High school students in the US and Canada, on topics like genetics, molecular biology, and bioinformatics.
  • Award: Cash prizes, scholarships, and internships at research institutions and biotech companies.

9. Genes in Space Challenge

Students design an experiment on how spaceflight affects genes and biology. The winning experiment actually gets run aboard the International Space Station, which is what makes this one stand out.

  • Eligibility: High school students (entered individually or in teams).
  • Award: Your experiment carried out on the ISS, plus mentorship and recognition.

10. Brain Awareness Video Contest

Run by the Society for Neuroscience, this contest has students make a short video explaining a neuroscience topic, judged on accuracy, creativity, and clarity.

  • Eligibility: High school students worldwide (roughly ages 13 to 18), as individuals or teams.
  • Award: $4,000 for first place (plus registration to the annual Neuroscience conference), $500 for second, $250 for third, and a $500 People’s Choice prize.
