Microlearning Lesson Plan: Forces and Magnetism
*Category*: Science & Curiosity
Lesson 1: Introduction & Fundamentals
*Objective:* Understand the basic concepts of forces and magnetism.
1. *Definition*: Forces are any interactions that, when unopposed, change
the motion of an object. Magnetism is a force caused by magnets when they
attract or repel each other.
2. *Reading*: Start with the article “Introduction to forces – KS3 Physics
– BBC Bitesize” which covers the basics of forces and their effects. [Read
here](www.bbc.co.uk/bitesize/articles/zs3896f).
3. *Video*: Watch “Year Three Science – Forces and Magnets” to see
fundamental concepts in action. [Watch here](
https://www.youtube.com/watch?v=b_gOhGWOKVw).
*Key Takeaways*:
– Forces can cause objects to start moving, stop moving, or change
direction.
– Magnetism is a specific type of force that acts at a distance.
*Activity*: Reflect on common uses of forces in everyday situations and
write down two examples where you encountered forces today.
Lesson 2: Practical Application & Techniques
*Objective:* Explore real-world applications of magnetism and learn
practical techniques.
1. *Definition*: Focus on how magnetism is applied in technology and
engineering, such as in motors and data storage devices.
2. *Reading*: Consult “Magnets and magnetic materials – BBC Bitesize” for
insights on how magnets are used in various industries. [Read here](
www.bbc.co.uk/bitesize/articles/z8g996f).
3. *Video*: Learn techniques to identify magnetic materials by watching “Is
it magnetic or non-magnetic?”. [Watch here](
https://www.youtube.com/watch?v=yorUUI5oClE).
*Key Takeaways*:
– Understanding magnetism can help in designing and utilizing various
mechanical devices.
– Magnetic fields can be harnessed for energy storage and conversion.
*Activity*: Identify household items that rely on magnetic principles and
jot down how magnetism is used in each item.
Lesson 3: Advanced Insights & Mastery
*Objective:* Deepen knowledge of forces and magnetism with expert insights.
1. *Definition*: Delve into advanced theories of magnetism in physical
sciences, including altermagnetism and its emerging research.
2. *Reading*: “Emerging Research Landscape of Altermagnetism” focuses on
cutting-edge research and theories. [Read here](
link.aps.org/doi/10.1103/PhysRevX.12.040501).
3. *Video*: “Exploring the Exotic: Nuclear Physics feat. Justin Stevens”
provides a deep dive into theoretical physics regarding forces. [Watch
here](https://www.youtube.com/watch?v=VV6VE_ic3M4).
*Key Takeaways*:
– Advanced magnetic theories pave the way for innovative technologies.
– Understanding exotic forces can lead to breakthroughs in scientific
research.
*Activity*: Reflect on how advanced knowledge of forces and magnetism can
benefit future technological advancements. List two potential innovations.
