1. BSCS 5E Teaching Model The Model is grounded in constructivism;
It consists of 5 phases: engagement, exploration, explanation, elaboration and evaluation;
The model is widely used in teacher training programme and it can facilitate inquiry-based learning with an emphasis on thoughtful inquiry and decision making;

2. BSCS 5E Teaching Model
This inquiry approach is also believed to be especially beneficial to gifted students who would prefer a more autonomous inquiry way of learning;
The model has been used in the design of BSCS (Biological Sciences Curriculum Study) curriculum materials since the late 1980s;and

3. BSCS 5E Teaching Model
there is research data supporting that BSCS 5E Model may help enhancing students’ inquiry and critical thinking skills as well as creativity.

12. Do you observe anything special about the bottle?
Engagement
If we put the beads into the bottle of water, it swells and we cannot distinguish them from the water since its refractive index is very near to that of water.
Do you observe anything special about the bottle?

13. 1.Engagement
Ask students to predict what would happen if they light 3 candles (tall, medium, short) at the same time and then put a gas jar over them.
2. Exploration – predicting, observing, communicating, inferring, constructing

14. 2. Exploration

15. 2. Exploration

16. 3. Explanation
Students are required to use mind maps to explain what they observed in the “candle” experiment

17. Explanation

24. 4. Elaboration
Elaboration-predicting, forming hypothesis, communicating
Student-applies concepts to a similar or new context
Teacher-provides similar or new context to apply ideas

25. 4. Elaboration Trying to find evidence to support the hypothesis
Carrying out further experiments

26. Students are required to design experiments to further explore the “candle” experiment. They may devise experiments to find evidence to support their hypotheses. Through such new experiences, they develop deeper and broader understanding, more information and skills in scientific investigations.

27. 5. Evaluation Any unclear areas or questions which may have developed?
Students are encouraged to assess their understanding and abilities.
Teachers can evaluate students’ progress.
