The teacher in me loves the science related badges. As we homeschool, I find that our curriculum often overlaps with badge work. This experiment is a classic example of one that we performed in “school”.
In early elementary school we studied the capillary action in plants. We watched as food coloring traveled up the stalk of celery. Gardening and Plant Science requirement #4 is the exact same experiment.
Here is a printable worksheet for you to use to help you track the food coloring as it travels. If you would like to use this pdf file, click on the image below to download.
NOTE: The requirements have been greatly simplified here. Please be sure to read the full text in the Girl Handbook to make sure you fully understand the requirements.
