The first was sent to us by our lab manager. It's a video. The first part demonstrates how we do science in our lab. Not!
The second is called plantingscience.org, and it allows graduate students, post-doc, professor, and other plant scientists to help kids from Kindergarten to high school with science projects involving plants. If you are involved in plant science consider signing up as a mentor and/or joining the Master Plant Science Team. It is a great way to help kids get excited about science, and improve science education in general.
