Help!?
I don't have a printed field guide or a magnifying glass—what can I use instead?
If you can't find a field guide or magnifying glass, use a plant ID app or online image search to match pictures for the 'plant name/page number' step and use your smartphone camera's zoom to examine and note leaf shape and flower color in your notebook.
What if my adult isn't sure the plant is safe or won't let us smell or take a sample?
If your adult won't agree to the safety, smell, or sample steps, take photos and only record the plant name/page number, traditional use, leaf shape, flower color, and growing location in your notebook and skip placing a leaf in the zip-top bag.
How can I change this activity for younger kids or older kids?
For ages 3–6, pick one plant and have an adult describe leaf shape and color while the child draws it in the notebook, and for ages 10+, have the child record GPS or map location, research chemical compounds behind the traditional use, and upload detailed notes to DIY.org.
How can we make this project more interesting or keep it long-term?
Extend the activity by gently pressing leaves from the zip-top bag into a homemade herbarium labeled with the field guide page number and traditional use, photographing each plant for your DIY.org post, and adding one short research note about the plant's traditional medicinal study to your notebook.
