    So you want to be a citizen scientist? The National Science Foundation (NSF) has got you covered. NSF supports citizen science across all areas of science, whether your passion is to scan the night sky, or explore your own backyard.

Join a flock of birders

    eBird is an online platform that allows bird-watchers to go online and record their sightings to a database. With more than 100,000 active users, eBird's system is a treasure of information on bird population, distribution and habitat, which users can explore in real time.

Count every drop

    The Community Collaborative Rain, Hail and Snow Network (CoCoRaHS) is the largest provider of daily precipitation observations in the United States. Volunteers set up rain gauges and record data every time a rain, snow or hail storm passes over. Data is organized and shared on the CoCoRaHS website, and used by scientists, farmers and more.

Search for stars with your computer

    Einstein@Home uses your computer's idle time to search for space signals. The project has already had major successes: Volunteers discovered about 50 stars, using data from Puerto Rico's Arecibo Observatory and Australia's Parkes Observatory. Einstein@Home also searches for gravitational-wave signals using data from NSF's Laser Interferometer Gravitational Wave Observatory.

Be part of a supercomputer

    To link all those home computers, Einstien@Home uses software called the Berkeley Open Infrastructure for Network Computing, better known as BOINC. The software choreographs(安排，筹划) the technical aspect of volunteer computing and helps you use radio telescope signals to search for alien life.

Join the plankton party

    Without plankton, life in the ocean would not exist. These tiny organisms form the base of the food chain, and play an important role in the global carbon cycle. Plankton Portal enlists citizen scientists to identify images of plankton, snapped by the In Situ Icthyoplankton Imaging System (ISIIS), an underwater robot engineered at the University of Miami. ISIIS has taken millions of images in oceans around the world and upload them into a database; classifying the images helps researchers understand plankton diversity, habitat and behavior.

    Helen Thayer, one of the greatest explorers of the 20th century, loves challenges. She says, “I like to see what's on the other side of the hill.” She has gone almost everywhere to do that.

    In 1988, at the age of 50, she became the first woman to travel alone to the North Pole. She pulled her own sled (雪橇) piled with 160 pounds of supplies, and during her trip no one brought her fresh supplies. Accompanied (陪伴) only by her dog Charlie, she survived cold weather and meetings with polar bears. In fact, Charlie saved her life when one of them attacked her. Near the end of her trip, a forceful wind blew away the majority of her supplies. The last week of the trip, she survived on a handful of nuts and a little water each day.

    Helen goes to challenging places not only for adventure, but also for education. Before her Arctic journey, she started a website called Adventure Classroom. On the site, she shares her adventures in order to motivate (激发) students. She explains, “Although kids often see the world in a negative way, without hope for their future, we work to inspire them to set goals, plan for success and never give up…” Helen grew up in New Zealand. Her parents were athletes and mountain climbers. Following how parents' example, she climbed her first mountain at 9. Later, she climbed the highest mountains in North and South America, the former USSR and New Zealand.

    In 1996, she took on another challenge-the Sahara Desert. She and her husband, Bill, walked 2,400 miles across it! In 2001, she and Bill traveled on foot from west to east through the Gobi Desert in Mongolia. They hope to travel in mainland China into Sichuan and Tibet to study pandas this year.

    Helen plans to continue taking trips. She'll use her colorations, writing, photography and environmental work to create programs for her Adventure Classroom website. She wants to inspire her students never to stop facing challenges!

    If you see a group of people dancing and singing on the street or in the railway station, you don't need to feel surprised. They are a flash mob(快闪族), which is a group of people who come together suddenly in a public place, do something unusual for a brief period of time, and then quickly break up. They are usually organized with the help of the Internet or other digital communication network. At a predetermined(预先决定的) time, they gather and perform some distractions(消遣) such as waving their hands and exchanging books. Then, they quickly break up before the police can arrive. Using mobile phones, the flash mob can change its location if the first one has been replaced for any reason.

    Bill Lasik, senior editor of Harper's Magazine, organized the first flash mob in Manhattan in May 2003 and the first successful flash mob came together on June 3, 2003 —after the first attempt failed at Macy's department store. Lasik claimed that the activity was designed to make fun of hipsters(赶时髦的人), and call attention to the cultural atmosphere.

    Flash mob gatherings can sometimes shock people. Such an activity might seem amusing and untrue, but it also might frighten people who are not aware of what is taking place. Undoubtedly, flash mobs can serve as good political tools in any direction. They also have great economic potential, such as using flash mobs to advertise a product.

    The flash mob is now becoming more and more popular. People use it to do many things. For example, in 2009, Michael Jackson's fans took part in a flash mob to remember him. Hundreds of his fans gathered singing and dancing Michael's famous song “Beat It” together. Flash mobs give people from all walks of life an opportunity to come together to create a memory.

For eight-year-old Toby, who is deaf, watching films or TV can sometimes be a bit pointless, because so many of them don't have sign language versions. "We have subtitles but it goes too fast," his dad Jarod Mills said. But now, Toby has some help thanks to an app developed by a 17-year-old student, Mariella Satow, who created a signing app called SignUp.

She got the idea when she was teaching herself American Sign Language(ASL)—one of hundreds of sign languages used across the world. Manella wanted to watch TV shows to help her learn, and she was disappointed to discover how few had signed versions. It's taken a year for Mariella to develop the technology, with lots of help from ASL teachers and the deaf community.

The app is available in the US as a browser extension—with an interpreter appearing in a box once the film starts playing. It only works on Disney Plus films at the moment, because that's where Mariella thought she could help the most children. Jarod, who works at a school for deaf children, says it was "exciting" watching Toby use Mariella's invention. He says, "Kids are getting information like any hearing child does."

Deaf people in the UK face many of the same barriers when it comes to cinema and TV. "A hearing person can go to the cinema any time whereas deaf people have to make sure there's a suitable viewing a time we're free," says 27-year-old Stacey Worboys from Cardiff. She has learned British Sign Language(BSL), and is comfortable using subtitles when watching TV shows and films. But she feels having an interpreter would make things "more inclusive", especially for someone who might struggle with subtitles. Stacey and Toby aren't the only people to be welcoming Mariella's app. It's now got thousands of users.

Stacey says a UK version of an app like SignUp would make films and TV "more accessible" for the deaf community. Mariella is up for the challenge—and hopes to make a British Sign Language version of her app for other streaming platforms such as Netflix and Amazon Prime. "There are more than 300 sign languages used worldwide, so it'll take a long time to get all of those versions out," she says.
