GRADE 10 & 12

L1

Fundamental Understanding

• What is Earth’s magnetic field?

• What causes the magnetic field?

• Simple explanation of magnetic pole shift.

• Activities:

• Label a diagram of Earth’s magnetic field.

Quiz on basic magnetic field facts.

L2

• Compare the magnetic field with a bar magnet.

• Use a simulation (like PhET) to see field changes.

  L3 – Advanced Application and Debate

• Projects:

  • Research and present on how pole shifts affect aviation, communication, and animal migration.

  • Prepare a mock news report from 50 years in the future after a pole reversal.

For Grade 8/9

Scientists have found away to break down lignin(wood waste) by using enzymes and using it into useful chemicals.

L1: Introduction of basic keyterms and the concept.

Enlist the need to find an alternative ecofriendly fuels.

Create simple illustrations

L2 Learners will understand the process and process of enzyme use in wood recycling

A group discussion can be initiated where the students will debate on the pros and cons of the enzymatic processes in industrial applications.

L3 Learners can either conduct an experiment of the breakdown of lignin. They can also create a model showing the enzymatic process using molecular kits to represent the chemical structures

L2

Grade 10

L1: Basic knowledge about magnets, their properties, earth's magnetic field and magnetic poles and shifts.

L2: Activities like mapping of earth's magnetic field and use of compass to understand how earth's magnetic field works.

L3: Interactive Simulations can be used from websites like 'PhET Interactive Simulations' which offer simulations on Earth's magnetic field and geodynamo. Also students can be encouraged to read scientific articles and present their findings via a research paper on geomagnetism and polar drift to deepen their understanding.

For grade 10,12 students-

L1- Define properties of magnets.

L2- Explain the functioning of Maglev trains. List the factors which are responsible for increased speed of Maglev trains

L3- How do hyperloop functions. Brainstorm on ideas that can make it more feasible economically.

Article- Shift in magnetic field

For grade 10, 12 students

L1- State the reason for earth's magnetic field.

L2- Suggest the consequences if earth stops rotating.

L3- Research about various planets in the solar system, which have magnetic field. Compare their magnetic field with the magnetic field of earth.
