How I Use It
In my school we have adopted NGSS and used this site's Bird Beak activity as an entry point to the grade 3 'Inheritance and Variation of Traits: Life Cycles and Traits' unit.
After a teacher driven intro, students broke out into groups and followed the steps for the activity from the website and recorded their data. This was great!
I wish that they had more units that lined up with NGSS. Until then, I don't think I can use it too much
