TRANSCRIPT
A new medicine is out on the market that helps people retain information better (smart pill). In a recent study, one group was given the smart pill and the other group was given a placebo (sugar pill) both groups were graded on a math test.
Identify:Control Group:Experimental Group:Independent Variable:Dependent Variable:
Identify the 4 unifying themes of Biology.
Explain what characteristics an organism must have to be considered alive.

What characteristics does a living thing have?Let’s make a class list:
1.
Think – Pair – Share
1. All living things share common characteristics
2. All living things share common needs
3. Living Things meet their needs through interactions with the environment
4. The types and numbers of living things change over time
1) Organized
i. All parts work together to take in nutrients and remove waste
ii. Body plan allows it to survive in its environment
Living things are arranged in an orderly way.
Cell- Smallest unit of life Ex. Liver cell
Tissue- group of cells that have same structure and function (look alike)Ex. –Skin
Organ- different tissues that work together to perform a function
Ex-Kidney
System- Group of organs working together Ex. Nervous System
Organism- Organ systems working together (whole)Ex. Gorilla
Tissue Organ System
Kidney
Bark
Group of cells doing the same thing
Intestines, stomach, mouth working together
Outer surface of a leaf
Heart, veins, arteries,
Muscle
2) Made of 1 or more cells.
Unicellular• a) Small, hard to see• b) directly exchange nutrients and waste with environment
Multicellular• a) Work together• b) cells have specialized jobs and work together to keep organism alive
3) Growth and Development
*Cell division and cell specialization*
4) Reproduction
Asexual: Sexual:1 Parent, 2Parents
Same DNA Mix DNA
1) All Living Things Share Common Characteristics

5) Responds to stimuli
6) Limited Life Span
1. Reproduction
A. Bacteria are unicellular.
2. Responds B. A seed turns into an oak tree.
3. Grows and Develops
C. Dogs live for an average of 10 years.
4. Made of Cells
D. All humans have digestive and respiratory systems.
5. Organized E. When a bug crawls on the venus fly trap, it closes.
6. Limited Life Span
F. A cat gives birth to kittens.
Identify the 4 unifying themes of Biology.
Explain the characteristics an organism must have to be considered alive
1) We need energy!!Energy is the ability to do work.The sun is the ultimate source of energy!
Can come from food and is converted into usable form, think calories
Energy moves along food web, only 10% of energy transferred to each level
Autotroph (Producers)
Heterotroph (Consumers)• Herbivore• Carnivore• Omnivore• Scavenger
2) Materials
A.) Water-Cells contain mostly water- Reactions within the body that occur need water
B.) Oxygen - for cellular respiration in animal and plant
cells
C.) Carbon Dioxide
-for photosynthesis in plant cells
D.) Nitrogen- For Proteins
3) living space
Protection
Sources of nutrients
Area to grow and develop
1) Environment: everything that surrounds an organism.Living factors (biotic factors)Non-living factors (abiotic factors)
Ex: sunlight, temperature, climate, rocks, etc.
2) Interactions- 2 or more things affecting each other.
Name at least 5 DIFFERENT interactions occurring in the following picture.
Biodiversity- variety of living organismsa. there are about 1.4 million different species
b. Species- group of interbreeding organisms
c. Fossils- are evidence of species existence; they have lived, died, and evolved over time.
What is an adaptation? characteristic of an organisms that
allows it to better survive in its environment
*Organisms within a species must adapt to changing environments or they will become extinct!!*
Read the handout for instructionsAssignment will be due……You must make an ORIGINAL CREATURE!!
