Here are some more ideas to get you started.
Engage the fives senses (whenever possible)
Make leaf prints ( paint the leaf and press the print into the journal)
Make leaf rubbings
Trace the items they are looking at
Add leaves into the journal using tape
Count the birds/squirrels/insects etc.
Measure as much of the phenomena as the students can using non standard and standard units of measurement.
Here is a downloadable lesson from John (Jack) Muir Laws and Emilie Lygren book: How to Teach Nature Journaling. All resources shared with permission. "I Notice..., I Wonder...?, It Reminds me of..."
GIVING FEEDBACK is a fantastic resource from Jack and Emilie
NOTE: You are encouraged to spend time in the outdoors Nature Journaling. However, you can also bring nature inside, look out your wonder window, have a refrigerator Safari or even observe a house plant or pet.
In separate columns list how we use these materials for everyday objects and/or structures
For example, stick(wood) is used to make furniture, houses and other items you can name
Do any of the materials need to be combined to create an item? For example, wood and minerals come together to make a pencil
NOTE: This can be used with the Nature Journaling activity at the top of the page.
