In my opinion, ferns are one of the coolest kinds of plants.
They are extremely versitile as they grow in a variety of habitats.
My favorite part is how the 'fronds' grow:

Leaf: The green, photosynthetic part of the plant. In ferns, it is often referred to as a frond, but this is because of the historical division between people who study ferns and people who study seed plants, rather than because of differences in structure. New leaves typically expand by the unrolling of a tight spiral called a crozier or fiddlehead. This uncurling of the leaf is termed circinate vernation. ~ thanks wikipedia

In that case, I have been watching the newest fiddlehead on my fern. This is something that I enjoy watching, I would usually check them out every time I water the little guy, but documenting it has been so rad! Being able to see the size change over time right in front of you all in a row is actually very powerful.

SO even though this is not the coolest task ever, it has made me consider some sweet curriculum for watching plant motions with my students someday!
In all the pictures I used a little 1 inchish plastic mermaid left over from my birthday last year (it was like an actual 'little green man' game on all our drinks :) ) These should help to show a constant in the view of how our little fiddlehead is grow to be big and strong, to one day maybe be the sporophyll frond that helps the little dude reproduce!
