Title: Big Ideas in Biology


1
Big Ideas in Biology
  • Unit 1

2
What are the Big Ideas?
  • They are unifying concepts found in all science
    biology, chemistry, earth science, physics
  • These ideas link the sciences together
  • This year we will study the following

3
Science as a way of knowing
  • Use observations, questions, and experiments to
    explain the world around us
  • Scientists looks for patterns
  • Scientists make predictions
  • Think about global warming

4
Interdependence in Nature
  • All forms of life are connected in our living
    planet
  • Organisms and their environment depend upon two
    processes the flow of energy and the cycling of
    matter
  • Think about a food web

5
Matter and Energy
  • Matter includes the nutrients that the body needs
    for survival
  • Energy is the fuel to run life processes
  • Think about the food pyramid in relation to
    healthy exercise

6
Cellular basis of life
  • All living things are composed of cells
  • Cells are complex and highly organized
  • Living things can be unicellular or multicellular
  • Think about the different types of cells found in
    your body and the different jobs they do

7
Information and Heredity
  • The genetic code determines all information of
    life
  • DNA carries the information from parent to
    offspring
  • Name at least 5 things that you inherited from
    your parents

8
Unity and Diversity
  • All living things are mostly alike at the
    molecular level but can take on a variety of
    forms
  • All organisms are made of carbon-based compounds
  • All organisms use protein for building
  • All organisms store info in genes
  • If we are so similar, how can we be so different?

9
Evolution
  • Evolution means a change over a period of time
  • Evolution has allowed us to adapt and to change
    in order for our species to survive
  • Think about species that have evolved in order to
    be alive today global warming is forcing some
    small species to evolve for survival squirrels,
    some birds, few insects

10
Structure and Function
  • Each living creature has structures that help it
    to survive
  • Each structure has a necessary function
  • List at least 5 common structures of humans and
    their functions

11
Homeostasis
  • This is an organisms ability to survive in a
    changing environment
  • All body systems are working successfully
  • Name 4 body systems and describe how they
    successfully keep you in homeostasis

12
Science, Technology, and Society
  • These three areas overlap
  • A critical balance between them is key to our
    survival
  • Should we used genetic engineering?
  • Should we stop global warming?
  • What is the best way to protect our water supply?

13

  • POST ASSESSMENT
  • What is the goal of Science, based upon what you
    learned today?
