This interactive activity from PBS Zoom takes kids through a virtual kitchen, testing various solutions to determine if they're acidic or basic. The solutions include mouthwash, vinegar, peppermint extract, bottled water, orange juice, and more. Students can visualize the change in pH as each substance is added to cabbage juice in an animated mixing process. In one animation, students test the acidity of each substance by trying to launch a virtual cork rocket.

6-8: 4D/M4. The temperature and acidity of a solution influence reaction rates. Many substances dissolve in water, which may greatly facilitate reactions between them.
6-8: 4D/M10. A substance has characteristic properties such as density, a boiling point, and solubility, all of which are independent of the amount of the substance and can be used to identify it.
6-8: 4D/M11. Substances react chemically in characteristic ways with other substances to form new substances with different characteristic properties.
8. The Designed World
8B. Materials and Manufacturing
6-8: 8B/M1. The choice of materials for a job depends on their properties.
6-8: 8B/M2. Manufacturing usually involves a series of steps, such as designing a product, obtaining and preparing raw materials, processing the materials mechanically or chemically, and assembling the product. All steps may occur at a single location or may occur at different locations.
