5. Module 1: How to Define Life (Day 1 out of 2)
The Nature of Biology
Module 1: How to Define Life
(Day 1 out of 2)

6. StudentsWillBeAbleTo
understand the steps of the scientific method
differentiate between an independent variable, dependent variable, and a control group

7. How do you design an experiment?
A. Problem/Purpose
1. The question the lab will answer
2. Identifies the independent and dependent variables
Independent variable – the factor the scientist changes from group to group (x-axis)
Dependent variable – the factor the scientist measures to see the effect of the independent variable (y-axis)
Scientific Method Song
Variables and Controls Videoclip

8. How do you design an experiment?
B. Research/Background Information
1. Lets the reader learn about the topic
2. Helps the scientist develop an educated hypothesis
C. Hypothesis
1. An educated prediction
2. Can be tested

9. How do you design an experiment?
D. Procedure/Experiment
1. Steps must be precise and detailed
2. Has one control group
Normal conditions or absence of independent variable
Used for comparison
3. Experimental group(s) have only one changing variable (which is the independent variable)
random fact: I moved to Charlotte last May

10. How do you design an experiment?
E. Observations/Data
1. Must be objective.
Good Example: The bacterial colony is yellow.
Bad Example: The bacterial colony is nasty.
2. Use measurements whenever possible.
Good Example: There are 50 bacterial colonies.
Bad Example: There are a whole bunch of colonies.

11. How do you design an experiment?
E. Observations/Data (continued)
3. Do not draw conclusions in the data section of the report.
Good Example: There are bacteria and fungal colonies in the shoe section.
Bad Example: The shoe was really dirty and so it was the most contaminated and grew a lot of stuff.
4. Should be organized.
May use a graph, table, or drawing(s).
Always include units of measurement and a title.

12. How do you design an experiment?
F. Analysis/Conclusions
1. Answers the purpose question.
2. Accepts or rejects the hypothesis.
3. Explains what can be inferred from the data.
G. REPEAT experiment!!!!
Design an Experiment - YouTube

13. How do we know it is “good science”?
Scientific knowledge is tentative.
1. Theories are the most logical explanation based on current evidence.
2. Laws are universal generalizations that are virtually unchanging.
***A hypothesis DOES NOT become a theory and then a law.

14. Key players Control group: provides the baseline for comparing data
Dependent variable: what we measure (placed on the y-axis)
Independent variable: what the scientist controls or changes (placed on the x-axis)
Experimental group: receives the variable being tested and is compared to the control group

15. Let’s Try this together!!!
Mr. Krabbs wants to make Bikini Bottoms a nicer place to live. He has created a new sauce that he thinks will reduce the production of body gas associated with eating crabby patties from the Krusty Krab. He recruits 100 customers with a history of gas problems. He has 50 of them (Group A) eat crabby patties with the new sauce. The other 50 (Group B) eat crabby patties with sauce that looks just like new sauce but is really just mixture of mayonnaise and food coloring. Both groups were told that they were getting the sauce that would reduce gas production. Two hours after eating the crabby patties, 30 customers in group A reported having fewer gas problems and 8 customers in group B reported having fewer gas problems.
What is the hypothesis?
What is the independent variable?
What is the dependent variable?
What is the control group?
What is the conclusion?

16. Group Activity (15 minutes)
You may choose one partner to work with
When you have your partner, pick up the pink sheet titled “Scientific Method - Constructing an Experiment”
Choose 3 experimental questions and follow the instructions on the paper.
Write your answers on a separate sheet of paper (check by Exit Ticket box).
Be prepared to share your favorite!!!

17. Independent Practice
Patrick believes that fish that eat food exposed to microwaves will become smarter and would be able to swim through a maze faster. He decides to perform an experiment by placing fish food in a microwave for 20 seconds. He has the fish swim through a maze and records the time it takes for each one to make it to the end. He feeds the special food to 10 fish and gives regular food
to 10 others. After 1 week, he has the fish swim
through the maze again and records the times for
each.
What was Patrick’s hypothesis?
Which fish are in the control group?
What is the independent variable?
What is the dependent variable?
What would be your conclusion?
How would you change this experiment?
*Show Ms. CL your answers

18. At the end of each module
Any resources (such as this PowerPoint) that could help you succeed at passing the Biology EOC with an 80% or higher will be uploaded on Ms.CL’s website:

random fact: I moved from the Tampa Bay area in Florida.

Day 2 of 2 for
Module 1

27. identify and define Characteristics of Life (STERNGRR)
SWBAT
identify and define Characteristics of Life (STERNGRR)
provide real-life examples of each STERNGRR term

28. How do you know something is alive?
Characteristics of Life - Alive! Videoclip
1. Organization (The level of complexity) a.
Organism
Organ System
Organs
Tissues
Cells
Molecules
Atoms / Elements
Meet the Elements - They Might Be Giants

29. Life Processes: STERNGRR
Synthesis – making materials
Transport – moving materials
Excretion – getting rid of wastes
Respiration – gas exchange AND production of energy (ATP)
Nutrition – gaining and using energy from food
Growth and Development – getting bigger and/or changing
Regulation – controlling internal processes
Reproduction – producing new cells or new organisms

30. How do you know something is alive?
SYNTHESIS
all living things build proteins
start at 1:08
random fact: I have 2 cats and a dog. My cats are named after musicians and my dog is named after a city in New Jersey.

31. How do you know something is alive?
Respiration
Organisms need energy constantly!!!!
They break down substances (such as breaking down food for Nutrition) and converting it into energy
Ex. Photosynthesis
first 2 minutes

32. How do you know something is alive?
Reproduction
Organisms must replace themselves so the entire species will survive.
May be asexual (only one individual contributes genetic material) or sexual (two individuals contribute genes).
Ex. plants reproductive organs are seeds (ovary) and pollen (sperm)

33. How do you know something is alive?
Growth and Development
Growth – to increase in size. Increases the number of cells of a multicellular organism.
Development – change that takes place in structure and function of an organism during its life cycle.
Example: Embryo becomes a fetus

34. How do you know something is alive?
Excretion
the process of eliminating or expelling waste matter
Ex: POOP!!!
also sweat and urine

35. How do you know something is alive?
Regulation
Homeostasis - the adjustment of an organism’s internal environment to maintain conditions suitable for life
*the brain is the major organ responsible for homeostasis
Ex: shivering in the cold, plants close their stomata

36. How do you know something is alive?
Transport
Organisms must transport nutrients to be used in cellular respiration to produce energy.
xylem and phloem
and the circulatory system are examples of transport
3 minutes

37. Group Activity (30 minutes)
Ms. CL will point out the posters around the room with our STERNGRR terms
Each poster will have 2-3 students
When I say GO each team will have 1 minute and 7 seconds to write down 2 examples of your term INCLUDE YOUR NAMES
When I say SWITCH you will move clockwise
At the new poster you will have 1 minute and 31 seconds to review the examples and then write 2 NEW examples
We will rotate a total of 7 times (8 terms)

38. Independent Practice (15 minutes)
Fold paper hotdog style
On the front, create 8 equal sections
Each section receives a STERNGRR term
Cut the sections
On the left inside flap, write the definition
On the right inside flap, write 3 biological examples of term
My oldest cat is Miles, my other cat is Otis, and my youngest pet (the dog) is named Parsippany, but we call her Parsnip for short.
