Bell Work Post-Its Write down four things that answers “What is Life” or “What does a living thing have that non-living things do not” Get with partner and stick matching Post-Its together If you have some that don’t match, explain to your partner what you meant Two-partner groups, get with another two-partner group and compare. Stick matching Post-Its together Explain the remaining unmatched sticky notes to others in order to convince them

Bell Work Focus Get book number from shelf that corresponds to your seat number From Pages 4 and 5, answer questions: Earth is home to an incredible diversity of life All living things and all the places they are found on Earth make up the _biosphere_. List at least five things that make up the biosphere Deserts, grasslands, forests, saltwater, freshwater, plants, animals, bacteria, fungi The variety of organisms in a given area is called biological diversity or _biodiversity_. _Biology is the study of all forms of life. Biology or life science is the study of _living things and their_interactions_with their environment. _Science_is the knowledge obtained by observing natural events and conditions in order to discover facts and formulate laws or principles that can be verified or tested.

Spiral Layout Day/Date: Enter Date Objective: Students will learn…
Greek/Latin Vocabulary: Term needed to help understand common terms or roots Vocabulary/Bell Work: Copy vocabulary terms and definitions and answer Bell Work questions in this section Assignment: Homework or things to prepare
5
Objective: Students will learn the characteristics of life
Day/Date: August 25, 2016 Objective: Students will learn the characteristics of life Greek Vocabulary: Bio- : Life -logy : Study of Vocabulary/Bell Work: Organism – any living thing Cell – Basic unit of life System – Organized group of related parts that intersect Assignment: Get with me if you haven’t taken the Lab Safety Quiz
6
The study of Life Biology seeks to understand the Living world
What is BIOLOGY ? The study of Life Biology seeks to understand the Living world
7
What Does It Mean to Be Alive?
Characteristics of Life REMEMBER: You need to fill in your notes with words that are in green.
8
All living organisms share some basic properties
Intro to Characteristics of Life
9
Made of Cells Smallest living thing Unicellular vs Multicellular
10
Organisms can be: Unicellular – one cell
Entire organism is made up of one single cell Bacteria and protists Multicellular- more than one cell The entire organism is made up of many cells Cells have specialized functions within the organism
11
Reproduction All living things Reproduce – produce offspring of their own kind Necessary for the survival of the species
12
Two types of reproduction
Asexual Reproduction A single parent organism reproducing by itself Sexual Reproduction Two different parent organisms (male and female) contribute DNA to produce a new organism. Bacterial Reproduction - E.coli
13
Based on a Universal Genetic Code
All organisms share the same basic genetic code, but every organism has a different arrangement of the genetic code Genes carry hereditary information Genes are composed of DNA DNA determines our inherited traits DNA is a BIOMOLECULE Nucleic Acid Nucleotides (Monomer) DNA (Polymer)
15
DNA code is passed from generation to generation.
The passing of inherited traits is the reason children look like their parents.
16
Grow and Develop All organisms Grow and Develop Growth
Physical change in size, over a period of time or an increase in the number of cells.
17
Development Change in the physical form or physiological make- up of an organism Physiology Study of functions in living systems. How your body works.
18
Need and Use Energy Living organisms need energy to grow, develop, repair damage, and reproduce
19
Metabolism The combination of all chemical reactions in an organism in which an organism build up or breaks down molecules Breaking down big molecules into smaller molecules + Building up big molecules = Metabolism
20
Respond to Their Environment
Organisms react to immediate changes or needs (stimulus) Stimulus: Something that causes a physiological response Response: Reaction to stimulus
21
Examples of Stimuli (plural for stimulus)
Light Temperature Sound Gravity Heat Water Pressure Plant response to light
22
Maintain a Stable Environment
Homeostasis (Internal Balance) External condition may change dramatically, but all organism must keep internal conditions relatively stable by the process of Internal feedback
23
Some examples of stable conditions in our body that are necessary for life
Body temperature Blood volume pH balance Water balance
24
Change Over Time Over multiple generations, organisms must change by adaptation to their environment and through the process of natural selection
25
Natural Selection Gradual process by which biological traits become more or less common in a population through reproduction and environmental influence.
26
Adaptation A process that enables organisms to become better suited to their environment
