As an introductory experiment to the topic of matter, WDE 5th grade students mixed a solid (baking powder) and a liquid (vinegar) to make a gas. Students enjoyed seeing the reaction of the combined products which made their ghostly hand raise on its own. Students decorated the gloves beforehand, and this gave each of the ghostly hands a unique personality. This experiment was the opening introduction to their study on properties and states of matter, physical and chemical changes, and mixtures and solutions. Submitted by Jessica Dawkins
