About This Lesson
Bring history to life through biology and chemistry as you make iron oak gall ink like Leonardo da Vinci did.
------
Have you ever walked in the shade of a mighty oak tree? In late summer or fall, you may find an odd little brown woody ball attached to a fallen twig. Look up into the tree, and you may see more attached to the twigs or leaves above you. Looking closely at these little wonders, you will probably find tiny holes all over them. What do you think these balls are? How do you think they are formed? You may be surprised by the answer!
