This is an activity I do with my students EVERY year. It is a poem (I did not write the poem, if anyone knows who did, I would love to give him/her credit. I found it on teachers.net years ago) that a witch (you) reads to your students in your best cackling voice. As you read, you add "ingredients" to your brew that represent the items in the poem. This demonstration is best done on an old-fashioned overhead projector in a clear dish so that the audience can see what happens to the brew as you add ingredients. The end appears magical for the children and provides them with a halloween school memory that will be hard to forget! Grab it here FREE!
