By the end of this lesson, the learner will be able to:
· Apply their understanding, knowledge and skills about acids and bases to new situations.
· Analyze the various properties of acids, bases, universal indicators, and the natural indicators to plan a new experimentation.
· Evaluate collaboratively the eco-friendly and sustainable options for chemical-based household items.
· Evaluate collaboratively about the importance of pH in daily life situations.
· Evaluate collaboratively to design an experiment.
Create their own experimental procedure to determine the most effective natural indicator in varying pH.
