  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 organism’s 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. Exit slide • POST ASSESSMENT – What is the goal of Science, based upon what you learned today?
