Induction stove. In an induction
stove an ac current exists in a coil that is the “burner” (a
burner that never gets hot). Why will it heat a metal pan, usually iron, but
not a glass container?
Practice with Lenz’s law
In which direction is the current, induced in the
circular loop for each situation in Figure below?
The Teacher observes and assesses each student’s
answer and provides fair and helpful feedback.
(P) Pair work.
Set qualitative structured questions in which
learners calculate the emf, current and magnetic
flux linkage using Faraday’s Law of Induction, Ohm’s Law,
Pairs checks and assesses each other’s answer and
provides fair and helpful feedback by using an answer sheet.
At the end of
the lesson, learners reflect on their learning:
has been learned
is necessary to work on
the learners could evaluate their own work as well as the work of their
classmates using certain criteria.
– how do you plan to give more support? How do you plan to challenge the more
– how are you planning to check students’ learning?
and safety regulations
will watch the video
take information from the texts
by questioning and dividing in group
with varied difficulties
Assessment – how
are you planning to check students’ learning?
The output for
the worksheet will serve as assessment
the lesson will also serve as formative assessment.
Be careful when use the laser-coder
the lesson objectives/learning objectives realistic? Did all learners achieve
my planned differentiation work well?
I stick to timings?
changes did I make from my plan and why?

(consider both teaching and learning)?
What have I
learned from this lesson about the class or achievements/difficulties of
individuals that will inform my next lesson?
