In this experiment, learners test multiple food items to see if they are an acid or base using an indicator solution created with red cabbage. Learners experiment with candy, fruit juice, milk, and any other edible items around your house they are curious about. Test items are separately added to a clear container with water before using an indicator to discover its pH level (pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base). Activity includes step-by-step instructions with photos, an activity video explaining the experiment process in detail, background info, suggested questions for caregivers to ask learners, suggested extensions. Adult supervision required when using stovetop or kettle.
