National Science Week is just five weeks away, so while you can still register an event, sign up to hold a SCINEMA screening or host Brain Break science morning tea, it's time to start looking for events to attend!

Thank you to the more than 1200 event holders who have registered their event on our website. National Science Week is a massively collaborative festival and it doesn't happen without your generous contributions of time, money and passion.

Thanks also to our volunteer committees in each state and territory, and to our our national partners and sponsors.

Host your own SCINEMA Community Screening during Science Week. Whether it’s at your school, library, in your local pub or even in your lounge room, you can host your own public or private event. All you need is a screen, computer, access to the internet and an audience (popcorn optional).

Be a part of National Science Week by hosting a Brain Break morning tea in your workplace or school. It's free to register and we'll send you quizzes and instructions for some sciencey activities to try together, as well as a poster and drink coasters. Don't forget to put your thinking cap on for some science-themed baking. Register now (closing 16 July).
