What comes from trees is a fun activity I use each year to go along with the Foss Science curriculum Paper and Wood. The essential question is what comes from trees? I start by showing the page and asking the students item by item if they think it comes from trees. I allow time for discussion and thinking. Then I give the paper to each student to do individually with a pencil. Then when we go back through it I only allow them to use a green crayon to circle the ones they didn't circle or cross out the ones they got wrong.
