In this free experiment activity, students will take a Potions Test to see if they are a wizard! The activity is an experiment to observe the chemical reaction created by combining vinegar and baking soda, although students are not told the common names of the ingredients until after the experiment is completed. To create a "wizardly" or "mad scientist" atmosphere, 4 pages of labels are included using the "scientific" names of common items ("Dihydrogen monoxide" = water, "Acetic acid" = vinegar, etc.) Also included are 2 pages of notes for the teacher and 2 printable student sheets, including activity instructions and an article on the science behind the experiment.
For another awesome freebie designed to be used in conjunction with this activity, visit The Rowdy Kids in 3's Tpt store to download her Wizards Magic Potion Test for Spooky Science
freebie. She has designed some great printable resources to be used with this file, including lab reports and slides to display during the experiment.
This is a fun, easy activity for Halloween or as an introduction or extension to a Harry Potter unit. It requires simple household ingredients (water, vinegar, baking soda, and food coloring) and can be completed in less than 30 minutes. by Rebecca Bettis
