Content Learning process

● Generation and transmission of Learning experiences and teaching strategies:
electricity Week 1:
● Magnetism, Electromagnetic forces and
induction ● Electricity is a versatile source of energy because it can be generated from various
● Alternating & Direct Current: sources, transmitted over long distances, and converted into different forms of energy,
foundational concepts and applications. making it essential for homes, industries, transportation, and modern technologies.
● Application of electromagnets - for ● The interdependence between electricity and magnetism: Electricity and magnetism are
example: Loud speaker (Sound waves closely linked phenomena, where a changing electric field generates a magnetic field and
connection) and transformers vice versa.
● Working of nuclear reactor, Nuclear
reactions - fission and fusion
● Advantages and disadvantages of Nuclear
energy (uses and dangers)
● After effects of nuclear accidents

8745934508
 ● Activity: Decoding the electricity bill of your house.
● The groups will be formed for research based presentation for formative assessment.
Week 2:
● Techniques and materials for creating electromagnets: Electromagnets are created by
wrapping a coil of wire around a ferromagnetic core and passing an electric current
through the wire, which generates a magnetic field.

● Practical skill - Measure the strength of a magnetic field

Week 3:
● Applications of electromagnetism in various fields: Electromagnetic forces are used in
various applications including electric motors, transformers, magnetic levitation, and
data storage devices.

8745934508
 ● Simulation of AC Generator will be used to further build on this concept.

https://phet.colorado.edu/sims/cheerpj/faraday/latest/faraday.html?simulation=generator.
● Practical skill - Investigate factors affecting the strength of electromagnets
● Formative Assessment
Week 4:
● Differences between alternating current (AC) and direct current (DC): AC voltage
alternates direction periodically, while DC voltage flows in one direction; AC is used
for power distribution, whereas DC is often used in battery-powered devices.

8745934508
 ● Transforming voltages using electromagnetism in devices: Electromagnetic transformers
are used to increase or decrease voltage levels in power transmission by using coils of
wire around a magnetic core.

● Transformer simulation: https://javalab.org/en/electric_transformer_en/.

Students will explore simulation using the above link to investigate impact of number of
turns on the output voltage. Students will be working on detailed written tasks on
criteria B and C. The guiding questions for the activity will be:
1. Create a valid hypothesis for the activity.
2. Identify the IV, DV and CV for the activity and mention the increments of the variables.
3. Write the detailed methodology for the activity related to the transformers.
4. Note down the readings from the activity in a data table.
5. Draw the graph between IV and DV.
6. Write a valid conclusion for the activity.
7. Mention the further improvements that you can suggest for the same activity.
Week 5:

8745934508
 ● The mechanism of sound propagation through different mediums: Sound travels as
mechanical waves through solids, liquids, and gases, with varying speeds depending on
the medium's density and elasticity.

● Practical skill- To determine the speed of sound

Week 6:
● The range and frequency of human-audible sounds: Humans can hear sounds within the
frequency range of approximately 20 Hz to 20,000 Hz, with sensitivity varying across
this range.
● Practical skill- Produce different sounds and observe if they fall within the human
hearing range.
Week 7:
● Working principles of loudspeakers and microphones: Loudspeakers convert electrical
signals into sound waves, while microphones convert sound waves into electrical
signals, both using diaphragms that move in response to sound pressure.
● Case Study- How Amar Bose Used Research To Build Better Speakers-

Week 9:

8745934508
 ● Causes and processes of nuclear decay: Nuclear decay occurs when an unstable nucleus
loses energy by emitting radiation in the form of alpha particles, beta particles, or
gamma rays.

● Effects of a nucleus being too large: If a nucleus is too large, it becomes unstable due to
the strong repulsive forces between protons, often resulting in alpha decay to achieve
stability.

Week 10:
● Factors contributing to nuclear instability: Nuclear instability can arise from an
imbalanced ratio of protons to neutrons, excess energy within the nucleus, or
structural deformation.

● Mechanisms of alpha, beta, and gamma ray emissions: Alpha decay releases helium
nuclei, beta decay involves the emission of electrons or positrons, and gamma decay
releases high-energy photons, all processes that stabilize the nucleus.

Week 11:
● Techniques for measuring and detecting nuclear decay: Nuclear decay can be measured
using Geiger counters, scintillation detectors, and other radiation detection instruments
that identify and quantify emitted particles.

8745934508
 ● Predicting when a nucleus will undergo decay: The timing of nuclear decay is
unpredictable for individual nuclei, but statistically described by a half-life, the time it
takes for half of a sample to decay.

Week 12:
● Natural and artificial sources of radioactive nuclei: Radioactive nuclei originate from
natural sources like cosmic rays and earth minerals, as well as artificial sources like
nuclear reactors and medical isotopes.
● Potential dangers and health risks of radioactivity: Exposure to high levels of
radioactivity can cause health risks including radiation sickness, cancer, and genetic
damage
● Guest lecture application on nuclear energy by Dr Ankur Kumar.
[ATL- ILS: Make connections between various sources of information]

Week 13:
● Beneficial uses of radioactive materials in various industries: Radioactive materials are
used in medical imaging and treatment, industrial radiography, food irradiation, and as
tracers in scientific research.
● Generating energy through the instability of nuclei: Unstable nuclei release energy
through nuclear fission or fusion, processes that are harnessed in nuclear reactors and
potentially in future fusion power plants.
● Case Study- Experimental challenges faced to develop atomic bomb-

of the unit.

8745934508
Summative Assessment
Students will appear for written assessment at the end of the unit based upon all the concepts
of the unit. All four criteria will be assessed during summative.

Differentiation
● CONTENT
As all concepts will be covered in class, students will be given adequate opportunities to
clear out their doubts and will also be tested at various occasions for their understanding
of the taught concept. Content is delivered through various mediums such as videos,
simulations, hands-on activities, etc. in order to provide various opportunities for
children to learn.
● PROCESS

For group or pair tasks mixed abilities groups will be made. Constant monitoring will be
done based upon the needs of the students. Extended and simple tasks will be assigned
according to the needs of the group. Tasks assigned are such that each student gets the
opportunity to showcase his or her learning.

● INSTRUCTIONS
Instructions will be simplified and broken down into smaller understandable steps for
students in need. Students will be provided with help to decode these.

8745934508
 After assessments, if the concepts seem to be unclear for a specific group of children
then they are given separate attention in the form of specially assigned classrooms for
revision and practice.

Reflection: Considering the planning, process and impact of the inquiry

Prior to teaching the unit During teaching After teaching the unit
Students have very basic knowledge about
magnets from day to day life. They have
learned about electric and magnetic fields in
MYP 4 as well. They have an understanding of
renewable and nonrenewable resources from
MYP 4 and from subject Individual &
Societies. They would be needed to perform
some basic calculations, which they have been
doing in previous years as well as in
Mathematics. Students have been working on
many activities which develop ATL skills
selected for this unit, not only in Physics but
in other subjects as well. Last year I
conducted this lesson in virtual setup, but
maybe I will have more challenges in terms of
delivering content if we switch to hybrid

8745934508
mode. Showing progression in ATL & LP is
another challenge I foresee.
