A Grade 3 class made these charming pressed flower/leaf collages. This project takes quite a while as you need to collect and dry the leaves. We went out one day during the summer and I gave each child a plastic container. They collected a variety of leaves and flowers. Back inside, I wrote their name on the cover an old magazine (one each) and then showed them how to separate the leaves/petals and lay them in-between paper towels.
Then I stacked them all and put some heavy books on them and left them to dry for about 2 weeks.
Then the kids simply made pictures with them- we used small paintbrushes and white glue to carefully apply them to cardstock. They could also add details with markers.
Then one of my high school girls saw these are was inspired to
create her own in her sketchbook:
