Use this Pine Cone Hygrometer Worksheet with the Pine Cone Hygrometer science activity. Do you think a pine cone can tell you the level of humidity in the air? Make your predictions, and see if you’re right! Use the worksheet to draw a picture of what your pine cone looks like before, during, and at the end of the hygrometer science project.

This experiment is best suited for students in Grades 5-9, but younger students will enjoy doing it with an adult’s help. Can you think of variations or improvements to the pine cone hygrometer? What about using cones from different varieties of evergreen trees? Keep track of your results for a weather prediction science fair project.

For more information about autumn, check out our Learn All About Autumn Science Lesson. You will discover why leaves change color, and why evergreen trees (like the one a pine cone comes from!) keep their leaves all year.
