My Home, the most sustainable lab

Science
STE(A)M
Students will explore through Inquiry by designing their own experimentation, the most effective natural indicators in varying pH using various household substances.

Concepts at a Glance

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.
