What Is Biology?

What is Biology? A.Biology= the study of life Bio= life + -ology= the study of B. Biologists organize living things into 6 groups called kingdoms. There are currently six kingdoms KingdomExample ArchaebacteriaExtremophile bacteria EubacteriaTypical bacteria ProtistaSeaweed, Amoeba, Slime Mold FungiYeast, Mushrooms PlantaeMoss, Fern, Holly, Oak tree Animalia, Fish, Birds, Frogs, Humans

LIVING OR NONLIVING? Biotic= living Abiotic=Nonliving -Made up of cells -“A”= without -Made up of cells -“A”= without unicellular & multicellular What are some examples of living and nonliving things?

How do you know something is alive? There are 6 Characteristics of all living things: Characteristics of Life Video Characteristics of Life Video Characteristics of Life Video 1. Organization (The level of complexity) Organism Organ System Organs Tissues Cells Molecules Atoms / Elements STERNGRR (life processes) starts here!

All living things are made of cells. i. One-celled organism – unicellular ii. Many-celled organism - multicellular 6 Characteristics of all Living Things

2. Energy Use / Metabolism  Synthesis  Transport  Nutrition  Respiration Synthesis = to make Transport = to move Nutrition = food Respiration = to make energy

Plants use light energy of the sun to SYNTHESIZE (make) food The blood is the body’s TRANSPORT system for moving oxygen, nutrients and wastes from one place to another. An organisms’ chemical reactions are called its metabolism

RESPIRATION is the process used by a living organism to break down food and produce energy NUTRITION (food) is needed by living organisms so it can be broken down

6 Characteristics of all Living Things 3. Reproduction 4. Growth and Development Reproduction = to make more individuals Growth (and Development) = to get bigger and change

REPRODUCTION occurs when more individuals are produced. Organisms reproduce so to replace themselves so the entire species will survive. GROWTH is getter larger and development is changing

6 Characteristics of all Living Things 5. Respond to stimuli  Regulation 6. Adjust to environment  Excretion Regulation = to adjust to changes Excretion = to get rid of

REGULATION includes responding to stimuli and making adjustments to help maintain homeostasis EXCRETION helps an organism to maintain homeostasis by getting rid of waste materials

Life Processes: STERNGRR  Synthesis – making materials  Transport – moving materials  Excretion – getting rid of wastes  Respiration – gas exchange AND production of energy (ATP)  Nutrition – gaining and using energy from food  Growth and Development – getting bigger and/or changing  Regulation – controlling internal processes  Reproduction – producing new cells or new organisms

Homeostasis  Organisms carry out the STERNGRR processes to maintain homeostasis  Homeostasis= to maintain a stable environment

Dead or Alive? Remember, Biotic= living Abiotic= nonliving Is Ebola a living thing? How Did Ebola Evolve to Affect Humans? How Did Ebola Evolve to Affect Humans?

Dead or Alive? Ebola is a deadly VIRUS that is affecting people in parts of Africa. Viruses : 1. Have DNA..... but no cellular structure 2. Can reproduce.....but only with a host 3. Use energy.... but this comes from the host cell’s machinery So....is the Ebola virus a living thing? What do you think?

EXIT TICKET Pick one of the 8 characteristics of life and describe it in detail. Be sure to provide an example to support your answer. Complete sentences only!!!

Warm-up: Check yourself 1. List the life processes: STERNGRR 2. What is the basic unit of life?

Can You Spot the Scientific Method? Greenhouse Biology

Don’t Forget…  Parent or guardian needs to review and sign the syllabus and policies and procedures and complete the information sheet (Due Monday 8/31 )  Materials needed by Monday  SIGNED DOCUMENTS ARE FOR A QUIZ GRADE!!!!  Sign up for Remind101 by Friday 8/28 for Extra Credit

Quick Write  Answer the following prompt in 4-5 complete sentences.  There are areas on the planet that experience seasons when water is overabundant, and times when there is not enough water. Drought is when there is too little surface or ground water. Drought can affect agriculture crops, and other plants as land dries up, keeping them from growing. Describe one way that you can save water that can be used when the planet is experiencing a drought. GUIDING QUESTIONS  What is the method? What are the details?  What materials are needed?  Consider how much this method of saving water will cost?  How easy or difficult it will be for people in less fortunate countries to implement?  

WHAT ARE ALL THE WAYS THAT WATER IS IMPORTANT TO US? HOW DO WE CURRENTLY TRY TO SAVE WATER?

OUR PLANET IS COVERED BY WATER!

Freshwater vs. Saltwater Remember, earth is covered with 71% water and the majority of that is saltwater.

THE SCIENTIFIC METHOD WHAT IS THE SCIENTIFIC METHOD?  An organized way to solve a problem through experimentation and observation

STEPS TO THE SCIENTIFIC METHOD 1. STATE THE PROBLEM 2. FORM A HYPOTHESIS (DO BACKGROUND RESEARCH first!) 3. CREATE AND CONDUCT AN EXPERIMENT 4. OBSERVE AND RECORD DATA 5. ANALYZE AND DRAW CONCLUSIONS 6. COMMUNICATE RESULTS THE SCIENTIFIC METHOD

1. STATE THE PROBLEM Form a question about a specific event. Example: Mouthwash kills bacteria. Which brand works best? THE SCIENTIFIC METHOD

 2. FORM A HYPOTHESIS  DO BACKGROUND RESEARCH FIRST!! Research the problem. Example: Read the labels of types of mouthwash. Which has the most antiseptic (germ- killing) ingredients? THE SCIENTIFIC METHOD

2. FORM A HYPOTHESIS  Make a testable educated prediction based on your Research.  A hypothesis can be recognized by an ?if, then ? Statement.  Example: IF Listerine has more antiseptic ingredients than Crest or the Wal-Mart brand, THEN it will kill more bacteria. THE SCIENTIFIC METHOD

3. CREATE AND CONDUCT AN EXPERIMENT  Create a way to test your hypothesis. -Create a CONTROLLED experiment. THE SCIENTIFIC METHOD

 A controlled experiment MUST have 2 groups. CONTROL GROUP : all conditions remain the SAME ! It is a group you do not do anything to. EXPERIMENTAL GROUP : a group or many groups who you test. The experiment is performed on this group. THE SCIENTIFIC METHOD

Establish the variables for your experiment. INDEPENDENT VARIABLE : the variable that you change or manipulate ( X axis for graphing) DEPENDENT VARIABLE : the change or result that happens when the independent variable is used ( Y axis for graphing) THE SCIENTIFIC METHOD

REMEMBER OUR HYPOTHESIS: IF Listerine has more antiseptic ingredients than Crest or the Wal-Mart brand, THEN it will kill more bacteria. THE SCIENTIFIC METHOD: MOUTHWASH EXPERIMENT Control Group- NO mouthwash Petri dish Bacteria grown from swab Listerine Crest Brand Wal-Mart Brand { Experimental Group

INDEPENDENT VARIABLE: Type of Mouthwash DEPENDENT VARIABLE: Amount of bacteria killed THE SCIENTIFIC METHOD: MOUTHWASH EXPERIMENT

4. OBSERVE AND RECORD DATA Run the experiment & document the data THE SCIENTIFIC METHOD

5. ANALYZE AND DRAW CONCLUSIONS Determine from the data collected if the hypothesis was correct or incorrect. EX: Listerine did kill more bacteria than the other brands because it had more antiseptic ingredients. THE SCIENTIFIC METHOD

6. COMMUNICATE RESULTS Share the results so the experiment can be repeated. THE SCIENTIFIC METHOD
