Do Now

1
Do Now

• GOAL We will be able to explain the
  characteristics of living organisms.
• Reminders
• Turn in Lab Contract, if you havent already.
• Have Material (BINDER) out on desk
• Begin Do Now before the timer goes off!

2
Ants Count

• We will be watching a short experiment and
  recording the different steps of the scientific
  method.

Characteristics of Living Things
4
Think-Write-Pair-Share

• You are an investigator on Earth and you have
  been contacted by an alien investigator. They ask
  you to describe in detail the difference between
  living and non-living things.
• (HINT remember that your description must be
  appropriate to include ALL living things such as
  bacteria, fish, plants and animals).

What is Biology?

• Biology ? the study of living things
• Bio Life
• ology study of
• Living things are classified into 5 groups
• Animals
• Plants
• Fungi
• Protists
• Bacteria

In Biology, we call these the 5 kingdoms of
living things.

Living vs. Nonliving

• Living things
• Biotic
• Called organisms
• Made up of CELLS
• (unicellular and multicellular)
• Examples
• Plants
• Animals
• people

• Non-living things
• Abiotic
• A no not
• Examples
• Soil
• Rocks
• Water
• Air

Organization of Living Things
9
Synthesis

• How organisms build necessary molecules
• Synthesis MAKE
• Examples
• Protein Synthesis making proteins from DNA
• Photosynthesis plants make food using energy
  from sunlight

10
Transport

• How organisms get what they need to cells
• Examples
• Circulation and absorption
• Active transport diffusion osmosis facilitated
  diffusion
• This keeps your body balanced and hydrated!

11
Excretion

• How organisms get rid of their waste and balance
  their fluids
• Examples
• Removing fluids to balance water
• Removing unused molecules from food (solid
  waste)

12
Regulation

• How organisms control body processes
• Examples
• Important to HOMEOSTASIS - to maintain BALANCE
  within the body
• Short term change based on stimulus (stimulus and
  response)
• allows living things to adapt to changes

Sweating reduces body temperature
13
Nutrients

• How organisms break down and absorb food
  (nutrition)
• Examples
• Fungi decompose dead remains (decomposer)
• Plants make their own food (autotroph)
• Animals consume other organisms and absorb food
  (heterotroph)

14
Grow Develop

• How organisms make new cells and develop
  necessary body parts
• Examples
• Birds develop in an egg
• Mammals develop in a uterus
• Fungi develop from a spore
• Plants develop from a seed

Grow to get larger in size body size
Develop to change due to hormonal or mental cues
15

• Living things are complex and made up of many
  levels

• 5. Organism
• 4. Organ System
• 3. Organs
• 2. Tissues
• Cells basic unit of life
• Atoms, Molecules
• Elements

16
Muscle cell
Muscle tissue
Heart
Circulatory System/ Organsim
17
Reproduction

• How organisms make new individuals like
  themselves
• This is the only one that is NOT required for the
  organisms survival, but is for the species
  survival!
• Examples
• Prevents Extinction
• Sexual vs. Asexual
• Internal or external fertilization

18
Respiration

• How organisms get oxygen and release carbon
  dioxide to make usable energy
• A series of chemical reactions that result in the
  release of energy (ATP energy for cells)
• Examples
• Anaerobic respiration NO oxygen
• Aerobic respiration oxygen
• Plants exchange gasses

19
Posters

• Each group will be focus on ONE characteristic
• On your poster
• DEFINE their characteristic in your own words
• PROVIDE an example of this characteristic
• DRAW a depiction of the characteristic.

20
HW

• Finish the back of last nights HW

21
Exit Ticket

• Pick one of the 8 Characteristics of life and
  describe it in detail. Br sure to provide an
  example to support your answer.
