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 here is a fantastic resource from Jack and Emilie
NOTE: You are encourage 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.
Take picture (*please be mindful of private property) or draw the details of each fence you discover
List the possible reasons for the fence - include human use, animal needs, environmental purposes
Brainstorm possible pros and cons for using the fence. Consider the impacts to the environment, how does weather (frozen/wet ground, strong winds, sunlight, rain, changing temperatures, and humidity) effect the structure/material, long/short term placement, materials used, the effects of forces from nature vs human, effects from internal forces acting on the fence and any other factors you feel are valuable.
If it is safe to do so touch and explore those fences to feel their rigidity, flexibility and sturdiness. Determine the good and bad qualities of these fences when you think of the factors you listed from your brainstorm
NOTE: This can be used with the Nature Journaling activity at the top of the page.
