Welcome students and briefly review the key ideas about liquid Crystals from the previous lesson.
Collaboration – Students are divided into small breakout groups to brain storm a range of ideas with the potential for Nanotechnology applications. A link to Padlet may be created for groups of students to post their comments.
Discussion – These ideas are further developed by the groups and then shared with the teachers and the whole class.
Investigation – Teacher engages students in a discussion about energy to investigate their current understandings. Q – What are the units of energy? Q – How much energy does a typical household use in a day or week? Q – In what form is most of the energy we use? Q – How does Nano technology relate to energy technology?
Discussion – Teacher to share the YouTube clip on Solar cells which is the last half of the video (from 2:26mins). Resources
Reflection – Q - How do photo voltaic cells work? Q – What is the photoelectric effect?
