NLSC. Chemistry-Engaging Quizzes for the New Lower Secondary Curriculum

1. Quiz 1: Acids and Bases Scenario: You are a chemist working in a water treatment plant. One day, you notice that the pH of the water supply has dropped significantly. Design an experiment to determine the cause of the decrease in pH and suggest a solution to neutralize the water.
2. Quiz 2: Chemical Reactions Scenario: You are a forensic scientist investigating a crime scene. A suspicious substance was found at the scene, and you need to identify whether it is an acid or a base. Design a simple experiment using household items to determine the nature of the substance.

Quiz 3: Stoichiometry Scenario: You are a pharmacist working in a hospital. A patient requires a specific dosage of a medication, but the available tablets have a different concentration. Calculate the number of tablets needed to achieve the desired dosage, taking into account the stoichiometry of the reaction.

Quiz 4: Organic Chemistry Scenario: You are a farmer trying to improve crop yield. You have heard about the benefits of organic fertilizers but are unsure about their composition. Research and explain the chemical components of organic fertilizers and their impact on plant growth.

Quiz 5: Environmental Chemistry Scenario: You are an environmental activist concerned about air pollution in your city. Design an experiment to measure the levels of air pollutants, such as carbon monoxide and sulfur dioxide, in different areas of the city. Discuss the potential sources of these pollutants and their effects on human health.
