Product Details

Watch paper chameleons magically change color with the help of some basic—and acidic—chemistry. Students spot solutions of various household substances on specially treated blotting paper, then estimate the pH of each by the color produced. Creativity flows as students then combine their scientific and artistic skills to make unique, colorful “chem”-eleons. A great integrated learning activity! Includes one acid and one base solution, five red cabbage indicator color charts, complete instructions with reproducible student handouts, valuable Teacher Notes and enough materials to make 30 chameleons.

Complete for 30 students working individually. Common household acids and bases are suggested, but not included.

Performance Expectations

MS-PS2-5: Conduct an investigation and evaluate the experimental design to provide evidence that fields exist between objects exerting forces on each other even though the objects are not in contact
MS-PS3-2: Develop a model to describe that when the arrangement of objects interacting at a distance changes, different amounts of potential energy are stored in the system.
HS-PS3-5: Develop and use a model of two objects interacting through electric or magnetic fields to illustrate the forces between objects and the changes in energy of the objects due to the interaction.
