Agenda – 8/31/2015• Take out your notebook, name tent, and a pen or pencil!

Set up Bell-Ringer pages in Notebook

Living vs. Non-living review notes

Think-Pair-Share w/ shoulder partner

Homework:

Syllabus/Lab Safety Contract, signature form on Moodle due by Fri. 9/4/15

1. On pages 1-4, divide the page into five sections to put your bell-ringers in this week (like below).

2. In the first box, Put the date and answer the bell question inside that box…We will use these entries for the next five weeks.

Think about your answer and discuss with your shoulder partner.

What is your definition of a living thing?

• Understand the five characteristics of life

Today’s Objectives:

• All living things depend upon other living and nonliving things to aid their

survival.

What are some living things you depend on?

What are some non-living things you depend on?

Section 2.1 Summary – pages 35 - 45

• All the living organisms (or once living) are called biotic factors.

• All organisms depend on

others directly or indirectly for food, shelter,

reproduction or protection.

BIOTIC FACTORS

• Biologists have created a list of characteristics that something has to have in order to be

considered LIVING.

• Only when something has ALL FIVE characteristics can it then be an organism.

ORGANISM = A LIVING THING

Characteristics of Living Things

• Whether an organism is made up of one cell or billions of cells, all of its parts function together

in an orderly, living system.

1. Has an Orderly StructureThis means that the organism has different parts that

work together for a common function. (Like the organs in your body)

• A species has to be able to reproduce in order to continue to

exist.

2. Can Reproduce

If a female human is infertile (can’t have children)- does she cease to be a living

thing?

3. They can Grow and Develop

• Growth results in an increase in the amount

of living material and the formation of new

structures.

• All of the changes that take place during the life of an organism are known as its

development.

• There are a lot of factors of the environment that can affect a living thing-

water, temperature, weather, air, other organisms in the area.

4. They can adjust to changes in the environment

• Anything in an organism’s external or internal environment that causes the organism to react is a

stimulus.

• A reaction to a stimulus is a

response.

• When an organism automatically adjusts to maintain a balanced INTERNAL environment

is called homeostasis.

• Living things reproduce themselves, grow and develop, respond to external stimuli, and maintain homeostasis by using energy.

5. Can Metabolize food• Metabolism is the breaking down or building of

molecules in your body.

• Digestion is a type of metabolism

• Organisms get their energy from food.

1. Plants and some bacteria make their

own food

2. Animals, fungi, and other organisms have to EAT in order to get

energy.

• The nonliving (never alive) parts of an organism’s environment are the abiotic factors.

• Examples of abiotic factors include:

• AIR CURRENTS

• TEMPERATURE

• MOISTURE

• LIGHT

• SOIL

THE ABIOTIC

• Abiotic factors have obvious effects on living things and often determine which species survive in a particular environment. (How?)

Question 1

Which of the following is a biotic factor?

D. light

C. earthworm

B. soil

A. moisture

Quickly discuss with the person next to you about:

The difference between abiotic and biotic factors

Question 2

Look at the side board, pick something that isn’t a characteristic of life….explain why.

Quickly discuss with the person next to you about:

The five characteristics of life and what they mean

Question 3

What is the difference between growth and development?

Quickly discuss with the person next to you about:

Responding to stimuli

Question 5

Describe a situation in which an organism responds to an external stimuli?

An internal stimuli?
