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 Abiotic=Nonliving
-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
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
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?
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.
