In this phase, students use their new knowledge in a different situation such as
extending conceptual understanding, practicing desired skills, and reaching to meaningful understanding by using
following disciplines:
Mathematic Discipline: Study questions about pH calculations are given to students and all of them are asked to
draw graphics about pH levels of some acidic and basic matters.
Technology Discipline: Students are asked to create a slowmation and a computer-based simulation about acid
rain cycles using a guide prepared by the researchers.
Engineering Discipline: Students work in groups in the laboratory. They use their newly acquired knowledge
