Title: 8/20 Due: Nothing (Thurs Signed form is due!)


1
8/20 Due Nothing (Thurs Signed form is due!)
  • No Brain Work Problem today
  • Make sure you have your composition notebook
    tomorrow!
  • Today Finish Rules/Procedures
  • Finish Get to Know You
  • Get to Know ME!
  • You are the Scientist
  • Scientific Summer

HOMEWORK Scientific Summer
2
YOU are a scientist in this classroom
  • Curiosity, honesty, open-mindedness, and
    skepticism are all necessary traits for becoming
    a scientist
  • Ask questions and look around for alternative
    explanations
  • Science is an ongoing process, not the discovery
    of unchanging, absolute truth

3
  • Jack and Judy were lying on the floor dead. There
    was a puddle of water and broken glass on the
    floor. How did they die?

4
  • Two men walk into a restaurant. The waiter brings
    them both beverages. The beverages are the same.
    One man drinks his glass down right away and
    nothing bad happens to him. The other man takes
    his time and drinks slowly. He dies. Why?

5
  • Mr.Smith lives on the 30th floor of his apartment
    building. Every day he takes the elevator from
    the lobby to the 15th floor and walks up the
    stairs the rest of the way. On rainy days he
    takes the elevator all the way from the lobby to
    the 30th floor. Why?

6
  • There is a room with a table, 53 bicycles, and
    four men. One of the four men is dead. How did he
    die?

7
  • A car stops in front of a hotel. A man turns to
    his wife and shouts Im ruined why?

8
  • There are 27 people in a cabin on a mountain. The
    windows and doors are locked, but everyone inside
    is dead. What happened?

9
  • An avid birdwatcher sees an unexpected bird. Soon
    hes dead. What happened?

10
Scientific Summer
  • When you are done, please sit quietly and wait
    for others to finish.
  • We will share with class!

8/21 Due Scientific Summer Get it out and put in
on your desk!
  • Brain Work Problem 1
  • Describe 3 observations you have made looking
    around the classroom.

13
I. Science--
  • A. Science is an organized way of using evidence
    to learn about the natural world
  • 1. Science is an ongoing process that involves
  • asking questions
  • observing
  • making inferences
  • testing hypotheses
  • B. Observations are made in science by using
    one or more of our senses.
  • Ex hearing, sight, smell, touch
  • 1. information by observations is called data
  • 2. Quantitative observations involve numbers.
  • Ex There are 134 oak trees

14
  • 3. Qualitative observations involve
    characteristics that cannot be measured like
    colors or texture
  • Ex The oak trees have orange and red leaves
  • C. Observations are usually followed by
    inferences.
  • 1. Inferences are what you can figure out
    based on what you already know (logical)
  • Ex If you take 5 samples from a pond and they
    are all clean enough to drink, you would infer
    that all the water in the pond is clean enough to
    drink

15
Observations Vs. Inferences Mystery
Footprints Fill in notes Observations
Inferences 1. 1.
2. 2. 3. 3.
16
  • D. A hypothesis is a possible answer to a
    scientific question or problem
  • 1. In science a hypothesis must be testable
  • Ex If the train is stuck, then I will be late to
    work.
  • Ex. If the coyote population decreases, then the
    number of deer will increase.
  • Use if, then statements
  • LETs Practice!

  • Qualitative Observation Quantitative
    Observation
  • Inference Hypothesis
  • 1. I just measured my room to be 15 X 15 feet in
    size.
  • 2. I noticed that all the peaches on that tree
    are rotten and have been for the past several
    months. The next peach I pick from that tree will
    probably be rotten as well.
  • 3. The dogs ears are brown and very fuzzy.
  • 4. The sky is clear today with no clouds it
    probably wont rain.
  • 5. The corn is dying because beetles keep eating
    little holes in the stalk. If we spray the corn
    with pesticides then it will survive better.
  • 6. That tree is at least 132 feet tall.
  • 7. There is no grass growing on that part of the
    lawn. If the dog stops peeing there, then the
    grass will grow back.
  • 8. That plant has purple buds in the spring and
    round red flowers during the summer.
  • THINK, PAIR, SHARE!

20
  • II. Scientific Method
  • A. Steps to the scientific method
  • 1. Stating the problem
  • a. do research-get data
  • 2. Forming a hypothesis (testable explanation)
  • If I give the plant 1 cup of water everyday, then
    it will
  • grow taller
  • 3. Controlled experiment that tests the
    hypothesis
  • a. Controlled experiments only allow for one
  • variable to changed at a time
  • Ex amount of water you give a plant- one
    variable
  • we changed

21
Run an Experiment How good are you at giving
directions??
  • On a sheet of paper, write down the directions on
    how to make a peanut butter and jelly sandwich
    for a person who has never made one before.

22
  • 1.) Independent variable the variable that is
    deliberately changed (manipulated)
  • Ex amount of water we gave the plant
  • 2. ) Dependent variable- the variable which
    responds to the change-measured (responding)
  • Ex How much the plant grew

    done. What did you learn from it?

Homework Independent/Dependent Poster
25
  • The "if" part of your hypothesis is the
    independent variable
  • The "then" part is the dependent variable.

If I increase the amount of time the flowers get
light, then they will bloom in a shorter amount
of time.
Identify the Dependent and Independent Variables
for each hypothesis! T.P.S.

  • Smithers thinks that a special juice will
    increase the productivity of workers. He creates
    two groups of 50 workers each and assigns each
    group the same task (in this case, theyre
    supposed to staple a set of papers.) Group A is
    given the special juice to drink while they work.
    Group B is not given the special juice. After an
    hour, Smithers counts how many stacks of papers
    each group has made. Group A made 1,567 stacks,
    Group B made 2,113.
  • Write a hypothesis
  • What is the
  • Control group

  • Independent Variable
  • What should Smithers conclusion be?

35
  • Bart believes that mice exposed to microwaves
    will become extra strong. He decides to perform
    this experiment by placing 10 mice in a microwave
    for 10 seconds. He compared these 10 mice to
    another 10 mice that had not been exposed. His
    test consisted of a heavy block of wood that
    blocked the mouse food. He found that 9 out of 10
    of the microwaved mice were able to push the
    block away. 7 out of 10 of the non-microwaved
    mice were able to do the same.

    claims to cause 50 longer lasting itches.
    Interested in this product, he buys the itching
    powder and compares it to his usual product. One
    test subject (A) is sprinkled with the original
    itching powered, and another test subject (B) was
    sprinkled with the Experiment itching powder.
    Subject A reported having itches for 30 minutes.
    Subject B reported to have itches for 45 min.

    that coconut juice will get rid of the green
    slime. Homers decides to check this out by
    spraying half of the shower with coconut juice.
    He sprays the other half of the shower with
    water. After 3 days of treatment there is no
    change in the appearance of the green slime on
    either side of the shower.

  • III. Testing spontaneous generation
  • A. Spontaneous generation is the idea that life
    can arise from something non-living
  • 1. People believed that maggots spontaneously
    appeared on meat
  • B. In 1668, Francesco Redi conducted a control
    experiment which proved that flies were to blame
    instead

62
Figure 1-8 Redis Experiment on Spontaneous
Generation
Redis Meat Experiment Control group? Independent
variable? Dependant variable?
Section 1-2
OBSERVATIONS Flies land on meat that is left
uncovered. Later, maggots appear on the meat.
HYPOTHESIS Flies produce maggots.
PROCEDURE
Uncovered jars
Covered jars
Several days pass
Responding Variable whether maggots appear
Maggots appear
No maggots appear
CONCLUSION Maggots form only when flies come in
contact with meat. Spontaneous generation of
maggots did not occur.

Needham vs. Spallanzani
Section 1-2
Gravy is boiled.
Louis Pasteur wanted to settle the argument once
and for all by designing an experiment where air
was allowed to reach the flask but microorganisms
were not. How do you think he did it?
.
Go to Section
64
C. Louis Pasteur again disproved the idea of
spontaneous generation by allowing air to reach
the broth but not the microorganisms 1. Showed
that all living things come from other living
things
Broth is free of microorganisms for a year.
Curved neck is removed
Broth is boiled.
Broth is teeming with microorganisms.

  • Brain Work Problem 8
  • What is spontaneous generation?
  • Give one example of an experiment that disproves
    spontaneous generation.

66
Give one, Get one Think Pair Share!
  • 1.) On a ½ sheet of paper write the word ME on
    the front and YOU on the back.
  • 2.) Try to think of 3 characteristics you think
    all living things share. Write this on the ME
    side.
  • 3.) Go around the room and GIVE one of your
    characteristics and GET one of someone elses.
  • 4.) GET 4 new characteristics.
  • 5.) Find a partner. Together narrow down your
    lists until you only have 8 characteristics
    total.

67
Due today Nothing
  • Brain Work Problem 8
  • List as many characteristics of life as you can
    remember

68
  • IV. Characteristics of Life
  • How do you know if something is alive?
  • A. Biology- study of life
  • B. Living things share 8 characteristics

69
  • ALL LIVING THINGS MUST
  • Reproduce- sexual- 2 different parents
  • Offspring different from parents
    each other
  • asexual- one parent
  • offspring are a copy of parent (clone)

70
2. Cell- smallest living thing unicelluar
organism is made up a single cell
multicellular organisms are made up of many
cells organized
into tissue, organs systems
71
  • 3. DNA- parents pass DNA to offspring
  • 4. Growth and Development- all organisms grow at
    some point in life some do metamorphosis

72
  • 5. Response to environment- Organisms live in
    constantly changing environments and must respond
    to stay alive.
  • Examples
  • 1) Days become shorter and the
    temperature
  • gets colder - Snowshoe hare changes color
  • 2) Your body temperature goes up - you
    sweat
  • (Identify the Stimulus the Response in these
    examples)
  • 6. Evolve- as a species, living things evolve
    over time

73
  • 7. Homeostasis- keeping body normal (temp,
    pulse, pH, etc.) despite external changes
  • Homeo-same
  • stasis- state
  • 8. Needs for materials and energy-Organisms must
    gain energy either from the sun or other
    organisms to survive

74
  • Living things need energy to grow, develop,
    repair damage, get food, avoid danger, reproduce,
    etc.
  • Sun ultimate source of energy for most life on
    earth
  • Autotrophs (plants, algae, and many bacteria) use
    the suns energy to make food.
  • Heterotrophs (animals, fungi, and many bacteria)
    ingest other organisms for food energy.

75
So what are the 8 characteristics of all living
things??
  • Reproduce
  • Made of Cells
  • Have DNAgenetic material
  • Grow and Develop
  • Respond to their environment
  • Evolve
  • Maintain Homeostasis
  • Obtain and Use Energy

76
  • Think of an organism.
  • Relate the 8 characteristics of life to this
    organism by drawing a picture of the organism to
    show the characteristics of life.
  • Please label or make a key,
  • showing the 8 characteristics.
  • BE CREATIVE!

Levels of Organization
  • Biosphere all parts of earth including living
    and nonlivng, atmosphere etc.
  • Ecosystem- all living and nonliving things in one
    area
  • Community-all living organisms in one area
  • Population-all organisms of the same species in
    the same area
  • Organism- individual living thing
  • Group of cells -cells with similar functions
    combine to make tissues, organs, organ systems
  • Cell smallest living unit
  • Molecule- group of atoms, nonliving

79

82
habitat
  • An organisms specific environment with
    characteristic living and nonliving factors

83
Species and Population
Redwing Blackbirds male and female

    samples are used

90
  • 2. Light microscopes-
  • a. uses two lenses
  • b. light from the base shines up through the
    specimen
  • c. Ocular lens is 10x, objective lens is either
    10x, or 40x
  • Ex What is the magnification of an object which
    uses the 40x objective lens?
  • Ocular 10x Objective 40x 400x
