If you haven't completed the 30-day Quest with TedEd's Earth School, I would definitely recommend it for some stimulating discussions with your kids.

Quest 26 was all about the nature of citizen science. Wherever you are in the world you can join a citizen science project to get involved with studying nature - and reporting back to support an ongoing natural science project - projects in which volunteers and scientists work together to answer real-world questions and gather data. 

Here are some websites to help you choose which project to get involved with - and there are thousands out there!

UK-based Big Butterfly Count - taking place until 9th August

Zooniverse - over 50 active online citizen science projects

Citizen Science Projects - learn about how you can participate in citizen science projects from the National Geographic

NASA's Citizen Science Projects - work on some real NASA science
