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 Homer Scenario 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. Bellringers 1 Date Just like this!

Think about your answer and discuss with your shoulder partner. What is your definition of a living thing?

2.1 Section Objectives – page 35 Understand the five characteristics of life Today’s Objectives:

Section 1.1 Summary – pages 3-10 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 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

Section 1.1 Summary – pages 3-10 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

Section 1.1 Summary – pages 3-10 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 Structure This means that the organism has different parts that work together for a common function. (Like the organs in your body)

Section 1.1 Summary – pages 3-10 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?

Section 1.1 Summary – pages They can Grow and Develop Growth results in an increase in the amount of living material and the formation of new structures.

Section 1.1 Summary – pages 3-10 All of the changes that take place during the life of an organism are known as its development.

Section 1.1 Summary – pages 3-10 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

Section 1.1 Summary – pages 3-10 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.

Section 1.1 Summary – pages 3-10 When an organism automatically adjusts to maintain a balanced INTERNAL environment is called homeostasis.

Section 1.1 Summary – pages 3-10 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

Section 1.1 Summary – pages 3-10 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.

Section 2.1 Summary – pages 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

Section 2.1 Summary – pages Abiotic factors have obvious effects on living things and often determine which species survive in a particular environment. (How?)

Section 1 Check 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

Section 1 Check 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?

Section 1 Check 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?
