1.1 What are the characteristics of living things?

WEB ACTIVITY: What is Life?
​Look at the gallery of pictures below and respond in your journal.
  • Which of these pictures is living and which is non-living?
  • How did you decide which was living and which was non-living?
  • Compile a list of characteristics that you think define something as living or non-living.

1.2 Where do living things come from?

Cell Theory

Modern Cell Theory states:
  1. the cell is a basic unit of life
  2. living things are made of one or more cells
  3. all cells come from pre-existing cells

The Cell Theory Rap

​Are viruses alive?

​ADVANCED: What is life?

​​This YouTuber, Jesse Agar, poses that viruses are not alive, rather they are perhaps just an object that isn’t alive any more than any other part of a cell is alive.  However, Jesse says that perhaps a virus that is inside a cell, is alive just like any other component of the cell.  To this definition Jesse Agar then poses the question: "Is the 'code' the individual, such that any set of DNA traveling and reproducing together is one organism or is the 'code' with the cell the individual since the cell is the smallest unit that performs life?"

1.3 How are cells different from one another?

Photosynthesis

Online Activity: Photosynthesis

  • ​Play the 'Photosynthesis Interactive' game to learn all about photosynthesis and where it occurs.  Once you click 'Start a New Game' you will see the 'Main Menu'; be sure to complete the 'Leaf Anatomy' and 'Light Dependent Reactions'.  Once you have played both games select the last option 'Score Sheet', print off this score sheet and submit it to your teacher.

EXTRA: Photosynthesis & Respiration

This is a good summary video which reviews both photosynthesis & respiration.

1.4 What interactions occur between humans and micro-organisms?

What are micro-organisms?

Bacteria vs Viruses

Flu Attack!

Symbiosis

  1. Mutualism: both species benefit
  2. Commensalism: one species benefits while the other is neither helped nor harmed
  3. Parasitism: one species benefits while the other is harmed

Are all viruses bad?

25 Bacteria facts that might make you feel dirty

Microbes use in Industry

  • viruses and bacteria can cause disease and can also be used in industry (ex. production of cheese and salami) and agriculture (ex. production of striped tulips)

1.5 How does the body protect us from pathogens?

The Immune System

  • the immune system provides a barrier to infections and a number of non-specific and specific responses to fight infection (ex. fever, antibodies, phagocytes, inflammation)

Epidemics & Pandemics

  • epidemics: regional outbreaks (ex. smallpox, measles)
  • pandemics: global outbreaks (ex. Spanish flu, SARS)

How Pandemics Spread 

Ebola Virus

Measles Virus

Smallpox

How a virus changes the world

  • different populations have greater immunity to certain infections than other populations (ex. impact of smallpox epidemic on First Peoples)

1.6 What medicines help protect us from microbes that make us sick?

Vaccines

  • vaccination can prevent the spread of infectious disease

Antibiotics

  • antibiotics are effective only against living organisms, such as bacteria, and not against viruses; overuse of antibiotics can lead to the development of antibiotic-resistant strains of bacteria ("superbugs")
