An inquiry-based approach to understanding acidity and alkalinity. Measure the pH values of various common solutions and create a broad spectrum of colours. Discover the range of indicators required to determine acidity and alkalinity. Also discover the range of acidity and alkalinity of various foods and the effect of acids on the function of our digestive enzymes. As a result, students will understand the difficulties the body faces in maintaining fluids at a constant pH and learn the importance pH plays in the chemical reactions necessary for biological activities, including growth and development, tissue repair and cell activity.
