All of the above REMINDERS DON’T FORGET -Return signed syllabus, safety contract, and parent information sheet by Monday 8/31 -Quiz Friday 8/28: Rules and Procedures, lab safety, STERNGRR -Unit 1 Test Next Week Is it alive? Observe the specimen on each table Write the name of the specimen Do you think it is living or nonliving? By non-living we mean anything that was never alive. List one reason why you think the specimen was either living or non living Answer the questions that follow 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 Kingdom Example Archaebacteria Extremophile bacteria Eubacteria Typical bacteria Protista Seaweed, Amoeba, Slime Mold Fungi Yeast, Mushrooms Plantae Moss, Fern, Holly, Oak tree Animalia , Fish, Birds, Frogs, Humans LIVING OR NONLIVING? Biotic= living -Made up of cells Abiotic=Nonliving -“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 1. Organization (The level of complexity) Organism Organ System Organs Tissues Cells Molecules Atoms / Elements STERNGRR (life processes) starts here! 6 Characteristics of all Living Things 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 An organisms’ chemical reactions are called its metabolism 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. NUTRITION (food) is needed by living organisms so it can be broken down RESPIRATION is the process used by a living organism to break down food and produce energy 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? 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?

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? Greenhouse Biology Can You Spot the Scientific Method? 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? https://www.youtube.com/watch?v=pIet8eXDfBk 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 THE SCIENTIFIC METHOD 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 (germkilling) 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: MOUTHWASH EXPERIMENT REMEMBER OUR HYPOTHESIS: IF Listerine has more antiseptic ingredients than Crest or the Wal-Mart brand, THEN it will kill more bacteria. Petri dish Control Group- NO mouthwash Bacteria grown from swab Listerine Experimental Group Crest Brand Wal-Mart Brand THE SCIENTIFIC METHOD: MOUTHWASH EXPERIMENT INDEPENDENT VARIABLE: Type of Mouthwash DEPENDENT VARIABLE: Amount of bacteria killed THE SCIENTIFIC METHOD 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. SOLVING THE WORLD’S DROUGHT PROBLEM… PROBLEM; RESEARCH: HYPOTHESIS: EXPERIMENT: IV: DV: CONTROL GROUP: EXPERIMENTAL GROUP: DATA: CONCLUSIONS: CAN WE USE OCEAN WATER TO WATER CROPS INSTEAD OF FRESH WATER?? PARTS OF A PLANT HOMEWORK Conduct your own research on plants. Write down three key facts about plants and plant growth and be ready to share one of them with the class tomorrow. Consider questions such as: What is needed for a seed to grow? Why are plants important to our ecosystem? What processes do plants carry out? **These are questions to get you started, you should also come up with your own!
