Enter the 2013 Google Science Fair

Google has opened its online international Science Fair for kids between the ages of 13 and 18. Students can work alone or in teams.

Find your passion, learn a little science and maybe win a prize.

To enter, you only need a little inspiration, an idea and a Google account. Sign up at GoogleScienceFair.com. After signing up, run your test or experiment and enter all information on the project site. Submissions are due by April 30, 2013.

After the first round of judging, we’ll announce 90 regional finalists, whose work will then be reviewed even more closely by a panel of judges. The top 15 students will be invited to our finalist event at Google headquarters in Mountain View, CA, where they’ll present their work to a panel of scientists, tech innovators and Nobel Laureates. In the end, we’ll be honoring three winners, including a Grand Prize winner.

What is the grand prize, you ask? Just a 10-day trip to the Galapagos Islands with National Geographic Expeditions and $50,000 in scholarship funding. There are also lots of other prizes for finalists and in age categories.

Meet Brittany, 17, the grand prize winner in 2012. Her winning project was an app to test for breast cancer.
