Warm-upUse the same sheet that you used yesterday to do warm-

upWrite today’s date (8/26) on your paper

A. 10 minutes B. 15 minutes C. 20 minutes

D. 25 minutes

2. When trying to cool hot glassware you should

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 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?

UNIT 1 VOCABULARY• Root • Stem• Leaf• Synthesis• Transport• Excretion• Respiration• Nutrition• Growth/development• Reproduction • Regulation• Homeostasis• Variable

• Independent/dependent

• Control• Experimental Group• Hypothesis• Data• Observation• Analysis• Biotic• Abiotic • Science• Biology

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.

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!
