MYP 8
Unit 1 - Diseases
Content
- What a disease is and the different types of disease (communicable vs. non-communicable diseases)
- The difference between a pathogen and a microorganism.
- The different types of microorganisms (that could be potential pathogens too): virus, bacteria, protozoa and fungi.
- Malaria - what it is, how it is transmitted, symptoms, how it can be prevented, treatment.
- How communicable diseases are spread (droplet, ingestion, air, contact, (STD's) vectors, etc.)
- Spreading of disease simulation - patient zero.
- What the Germ theory is, the scientists who developed it and how it changed today's world.
- Physical barriers - skin, mucus, ear wax, tears, etc.
- How effective the skin is at protecting the body.
- Immune system - passive and active immunity.
- History of vaccination - Edward Jenner
- How vaccines work.
- MMR vaccine case study.
- What antibiotics are, types of antibiotics, and how using antibiotics helps the immune system fight infections.
- The misuse of antibiotics in food, agriculture, etc.
- Diseases throughout history - Black Death, Spanish flu, Measles, etc.
Skills and understanding
- Research skills in the research task on Malaria.
- Develop thinking skills by simulating the spread of disease.
- Develop critical thinking skills by experimenting with apples to simulate the skin as a protective layer.
- Organise events in time (germ theory timeline).
- Develop critical thinking skills by discussing MMR vaccine data (two sides of an argument).
Unit 3 - Motion, gravity and our solar system
Content
- Force of gravity and its relation to the mass of big objects in the Solar System (Earth vs. Moon)
- Acceleration and Force: how motion of objects are affected by mass and amount of force.
- Mass and weight and concepts behind a gravitational field (force per unit mass, as in "g" of Earth = 10 Newtons/kilogram)
- Relationship of inertia and mass.
- Gravitational force between big objects, circular motion in the Solar System, orbits (elliptical, vs. circular), path
- Newton's law of universal gravitation , force is proportional to mass of objects and inversely proportional to distance squared.
- Space exploration impact on modern technology , benefits and costs.
Skills and understanding
- Relate time and distance, resulting in speed
- Apply the concept of 'gravity' as a force that changes the speed difference between mass and weight (apply F=mg), on different planets?
- Visualise objects in an orbit around the earth as continuously falling
- Understand the challenges of space exploration programs are related to lack of gravity and air.
- Use Newton's second law:- an unbalanced force will cause an object to speed up, slow down or change direction
- Use Newton's first law:- balanced forces (or no forces) will mean an object either stays at rest or continues at constant velocity.
