2.  Agenda :  HW Recap: Data Analysis  Discussions: What does it take to be considered “living”?  Application: Analyze samples and defend whether they are living or not.  Did you finish your Mythbusters anaylsis? --------------------------------------------------------------- -Warm up: 1. Discuss with your group and list 4 ways you are like this tree. ------------------ HW: Study for your Quiz tomorrow. Thursday August 1, 2013

3. Characterisitics of Life

4. Biology – What’s in a name?? What dies BIOLOGY mean? “Bio-” means “life” “-ology” means “the study of” All living things share characteristics but are also influenced by there surroundings. Factors that affect living things… BIOTIC factor– references aspects that affect life that are considered “living” includes something that is DEAD – because it was once living ABIOTIC factor– references aspects that are NON- living (but can be just as important) “A-” is a prefix for “opposite of” or “against”

5. Shoulder Partner… Talk it over and come up with any 3 biotic factors and 3 abiotic factors. 1 minute… GO! Quick share…  What are the biotic & abiotic factors in this scene?

6. What organisms are considered living? Animals FungiPlants ProtistsBacteria

7. What are the 7 basic characteristics of all living things?

8. What does it mean to be alive? Move? Reproduce? Breath? Eat? Heart Beat? Drink Water? Cells?

9. Cellular Organization All living things are made of one or more cell. Highly organized structure And there is a hierarchy of organization in living things. Organism Organ System Organ Tissue Cell Organelle Multicellular Organisms Single Cell Organisms

10. Metabolism / Use energy Obtain and use energy (Eating, Breathing, Drinking Water) What do all food chains start with? Plants transfer sunlight into chemical energy. Your cells need energy to grow, develop, repair damage, reproduce

11. Homeostasis Maintaining stable internal condition when the outside can change. What is a humans normal internal temperature? Stability is incredibly important to our chemistry!

12. Growth & Development All organisms grow and change There is a life cycle for every organism, some more dramatic than others.

13. Reproduction/ Heredity All organisms reproduce in order to continue the species’ existence. Genes (heredity) are passed on from parents to offspring. Therefore, offspring are a mosaic of traits from contributing parents.

14. Response! Respond and Adjust to Environment All organisms respond to changes in their environments. Example Light Gravity Heat Fight or flight Phototropism Auxin, a growth regulator in plants, controls directional cell elongation that takes place in phototropism

15. Evolution Populations of organisms change over time leading to the great diversity in life we see. 4 Tenets of Evolution 1.Variation 2.Traits are passed on 3.Overproduction 4.Many offspring don’t survive because of competition.

16. Double Check Let’s reconsider the question about the tree. Which characteristics did you include? Which characteristics do you need to change? Which characteristics do we need to remove? Honors

17. Practice Identifying the Characteristics in Samples… In your groups, analyze the picture and decide if it’s living or not. Give three reasons for each.

18. Continuing… Yesterday you refreshed with what the characteristics of life are. How did you do on the homework? 1. Polar Bear = Living 2. Rock = Not Living 3. Sunflower = Living 4. School of Fish = Living 5. Dirt = Not Living 6. Euglena = Living 7. Seeds = ? Turn these in for credit. BIO

19. Concept Check Is it Living?... Why?

20. Today… You will choose an organism. If you have been reading the warm-ups you should have brought in a picture from home. You will use this picture as the focus for examining the properties of life further.

21. Properties of Life Graphic Organizer

22. Is it living? “Living” is an important term that has very specific definitions. Unfortunately, it can sometimes be difficult identify all of them in living things. You know most of these properties already. Recall yesterday’s question about the tree. What were you ideas? How about the apple?

23. 1.Cellular Organization All living things are made of one or more cells. 2.Metabolism Living things break things down then build things back up. This is evident in obtaining energy to live (eating other organisms) 3.Homeostasis Maintaining stable internal conditions when things outside change. For example, we shiver when it’s cold and we sweat when it’s hot but our internal temperature stays pretty stable. 4.Growth & Development Living things grow in size or number in cells and have a life cycle, they live and then eventually die. 5.Reproduction/Heredity Living things make babies (officially called offspring). Those babies have traits given from their parents. Meaning they have genes (eye color for example) that were given to them by their parents. 6.Interaction/Responsiveness Living things respond to outside influences. Flowers open in sunlight and gazelle run when chased. 7.Evolution As generations increase, random mutation and genetic combinations contribute to variability. These 7 terms define what is living. All life is united by these 7 properties. 7 Properties of Life

24. Properties of Life Classwork Choose your organism, any organism. – This should be the organism you brought in. – You can draw one or make it up if you didn’t. Draw or paste a picture of this organism in the middle of the page. – See next slide. In bubbles around the outside, label, define, and describe the 7 properties of life and how this organism displays using them. Once graded, these could be put up on the side wall.

25. Due: Monday 8/5 Use color & Be neat & creative. Do this on a piece of copy/construction paper provided. Property of Life: Explanation Ex: Metabolism: the sum of chemical reactions in the body that help build up & break down the organism. The alien eats carbon asteroids that fall from its moon for energy. Property of Life: Explanation Property of Life: Explanation Property of Life: Explanation Property of Life: Explanation Property of Life: Explanation Scoring: 25pts Total 1pt. ea.: Each property is labeled. 1pt. ea.: Each property is defined properly. 1pt. ea.: Each property is related to your organism in a descriptive manner. 4pts total: Presentation is neat and colorful!
