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

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
2. Energy Use / Metabolism
Synthesis
Transport
Nutrition
Respiration
Synthesis = to make
Transport = to move
Nutrition = food
Respiration = to make
energy
![Page 10: Warm-up Use the same sheet that you used yesterday to do warm-up Write today’s date (8/26) on your paper 1. If a chemical splashes in or eyes of on your](https://reader036.vdocument.in/reader036/viewer/2022062409/5697bfa71a28abf838c98e1f/html5/thumbnails/10.jpg)
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
![Page 11: Warm-up Use the same sheet that you used yesterday to do warm-up Write today’s date (8/26) on your paper 1. If a chemical splashes in or eyes of on your](https://reader036.vdocument.in/reader036/viewer/2022062409/5697bfa71a28abf838c98e1f/html5/thumbnails/11.jpg)
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
![Page 13: Warm-up Use the same sheet that you used yesterday to do warm-up Write today’s date (8/26) on your paper 1. If a chemical splashes in or eyes of on your](https://reader036.vdocument.in/reader036/viewer/2022062409/5697bfa71a28abf838c98e1f/html5/thumbnails/13.jpg)
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?
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?

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?

THE SCIENTIFIC METHOD
WHAT IS THE SCIENTIFIC METHOD?
An organized way to solve a problem through experimentation and observation
![Page 31: Warm-up Use the same sheet that you used yesterday to do warm-up Write today’s date (8/26) on your paper 1. If a chemical splashes in or eyes of on your](https://reader036.vdocument.in/reader036/viewer/2022062409/5697bfa71a28abf838c98e1f/html5/thumbnails/31.jpg)
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
![Page 32: Warm-up Use the same sheet that you used yesterday to do warm-up Write today’s date (8/26) on your paper 1. If a chemical splashes in or eyes of on your](https://reader036.vdocument.in/reader036/viewer/2022062409/5697bfa71a28abf838c98e1f/html5/thumbnails/32.jpg)
1. STATE THE PROBLEM
Form a question about a specific event.
Example: Mouthwash kills bacteria. Which brand works best?
THE SCIENTIFIC METHOD
![Page 33: Warm-up Use the same sheet that you used yesterday to do warm-up Write today’s date (8/26) on your paper 1. If a chemical splashes in or eyes of on your](https://reader036.vdocument.in/reader036/viewer/2022062409/5697bfa71a28abf838c98e1f/html5/thumbnails/33.jpg)
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
![Page 34: Warm-up Use the same sheet that you used yesterday to do warm-up Write today’s date (8/26) on your paper 1. If a chemical splashes in or eyes of on your](https://reader036.vdocument.in/reader036/viewer/2022062409/5697bfa71a28abf838c98e1f/html5/thumbnails/34.jpg)
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
![Page 36: Warm-up Use the same sheet that you used yesterday to do warm-up Write today’s date (8/26) on your paper 1. If a chemical splashes in or eyes of on your](https://reader036.vdocument.in/reader036/viewer/2022062409/5697bfa71a28abf838c98e1f/html5/thumbnails/36.jpg)
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
![Page 37: Warm-up Use the same sheet that you used yesterday to do warm-up Write today’s date (8/26) on your paper 1. If a chemical splashes in or eyes of on your](https://reader036.vdocument.in/reader036/viewer/2022062409/5697bfa71a28abf838c98e1f/html5/thumbnails/37.jpg)
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
![Page 38: Warm-up Use the same sheet that you used yesterday to do warm-up Write today’s date (8/26) on your paper 1. If a chemical splashes in or eyes of on your](https://reader036.vdocument.in/reader036/viewer/2022062409/5697bfa71a28abf838c98e1f/html5/thumbnails/38.jpg)
REMEMBER OUR HYPOTHESIS: IF Listerine has more antiseptic ingredients than Crest or the Wal-Mart brand, THEN it will kill more bacteria.

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!
