Forms and a Dichotomous Key
A great way to use technology
The two system mouse, right. Di is two. and a mouse at the end. Makes sense to me.
You can use Google Forms to create sections. In using multiple choice questions direct students to a new section based upon an answer. Reminds me of those choose your own adventure stories once again but with science.
There is a great web entry on the process along with a YouTube video at http://www.techycoach.com/2016/04/get-classified-create-dichotomous-key.html
Thanks and don't forget to be awesome,
