Collect or document three unique/different plants growing in your local environment. It doesn’t matter if it’s from the forest, your yard, or the sidewalk. 

(If you do decide to build plant mounts be sure you are collecting from an authorized area:)

Materials

Scissors 
3 sheets of newspaper
2 – 4 pieces of cardboard
Glue/tape
White poster board for mounting dried samples on 

Plant Mounts

ind three different species of plants you would like to document (grasses and flowers/weeds are easiest to press)
Collect one stem from each plant and place in a newspaper fold. You want to try and get at least a portion of the stem with the leaves and flower/seed of each mount. If the plant is too large to fit in one piece you can cut the leaves and flower separately. 
Place each plant flat in separate newspaper folds and then in between two pieces of cardboard place a weight (big books work great:) of some variety on top of cardboard and let dry for 3 days.
Remove each plant from newspaper and attach to the poster board with either glue or tape.

Materials

Camera or camera phone 
White poster board for backdrop

Plant Photos

Find three different species of plants you would like to document, place the poster board close behind each so that it is only the plant and the white background in the picture. 
As with the plant mounts, try to include portions of the plant stem, leaves, and flower/seed for each photo.
