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.

Do you think we can blow up a balloon using only ingredients from the pantry? Using simple, safe, at-home materials, we will explore the concepts of pH and acid-base chemistry and have some fizzy fun! With their signature gas-producing fizz, the acid-base reactions in this episode are both fun and functional. Not only will the reaction blow up a balloon, it also makes your bath bomb fizz in the tub. Join Miss America 2020 to cook up some science in your kitchen, and learn more about the chemistry of fizzy fun! Developed for students in grades 6- 10.

NASA eClips Our World: Where Do We Find Extremophiles?Video Description: Where do we find extremophiles? We look for environments that push the limits for ordinary living organisms. NASA conducts analog testing in these extreme environments to better understand life on Earth and identify the potential for life in the universe. Video Length: 3:25. NASA eClipsTM is a suite of online student-centered, standards-based resources that support instruction by increasing STEM literacy in formal and nonformal settings. These free digital and downloadable resources inform and engage students through NASA-inspired, real-world connections.NASA eClips Our World videos (grades 3-5) help students understand the differences between science (the natural world) and engineering (the designed world). These video segments supplement elementary learning objectives not only in science, technology, engineering and mathematics, but also in reading, writing, visual and performing arts.
Test the pH of things like coffee, spit, and soap to determine …
Test the pH of things like coffee, spit, and soap to determine whether each is acidic, basic, or neutral. Visualize the relative number of hydroxide ions and hydronium ions in solution. Switch between logarithmic and linear scales. Investigate whether changing the volume or diluting with water affects the pH. Or you can design your own liquid!
