We are dedicated to providing accurate and engaging content for teachers. Our lesson creation team consists of researchers, marketers, teachers, and healthcare professionals. Content is created and reviewed based on the credibility of the original sources and the objectivity of the findings, and is cross-referenced with the needs of the provincial curriculum. For detailed information on our lesson planning process, please read the “Who We Are” section.
All our lessons are available for free for use in your classroom. Our current list of lessons includes:
- What is the Immune System?
- The Innate Immune System
- The Adaptive Immune System
- How Vaccines Work
- Types of Vaccines
- HPV, Tdap, and Meningococcal Vaccines
- How Antibiotics Work
- Outbreaks, Pandemics, and Epidemics
- Inequalities in Childhood Immunization
- The Role of NGOs in Global Health
- Evaluating Information Sources
- ...and many more!
In addition, you can see sample lessons below:
The innate immune system is our body’s first line of defense against pathogens. It is a generalized, non-specific defense system (meaning that the defenses protect against all pathogens).
The innate immune system defenses consist of the protective mechanisms we are born with (innatemeans “inborn” or “natural”). These include physical barriers like our skin and mucous membranes, chemical barriers like saliva and stomach acid, immune system cells like macrophages that are constantly on the lookout for pathogens to destroy, proteins like cytokines (chemical messengers that immune cells use to communicate with one another), and the inflammatory response (inflammation). In most cases the innate immune defenses are enough to fight off pathogens before they can cause an infection but when they aren’t, the adaptive immune system is called into action (the adaptive immune system is covered in the next lesson).
