Description
- Overview:
- The students will analyze the pH of four citrus fruits: lime, lemon, orange, and a grapefruit, and then they will analyze the pH of four different types of stain removers:
Shout Advanced, Spray 'n Wash Max, Oxi Clean Laundry, and Clorox Oxi Magic. Using their learned information, they will predict and then analyze the pH of a final cleaning solution Bathroom Lime & Scale Remover, which is a Green product.
Students will use two methods of determining the pH for comparison. This will be done utilizing pH litmus paper and creating a cabbage indicator solution.
Students will also read labels, list the first few ingredients, and identify sales tactics used for their products such as eye-catching phrases. (Language Arts)
Finally, students will discuss and share their results as a class. Students need to answer what do citrus fruits have to do with cleaning? What product is most effective? Students need to support their answer with data from their experiment.
