B. 100
C. as many as you want/required

Answer 1

A. There are 3 (standard!!) of the same exact experimental setups in a fair test.

Question 2

D. basis for comparison
E. essential for observation/problem identification

Answer 2

D. basis for comparison

Question 3

Did the student use the scientific method properly? If not, correct what needs to be corrected.

Student: Rory Gilmore

• Observation/Problem: Will too much sunlight kill a tomato plant?
• Hypothesis: If tomato plants will be exposed to more sunlight, then the plant will significantly grow taller.
• Experimentation/Data Gathering:Dependent Variable ✔ (height of the plant)
  Independent Variable ✔ (exposure to water)
  Constant Variables ✔ (type of soil, amount of water received, type of seed, size of the pot, temporary on-exposure setting etc.)Setup Summary:

   A - Exposed only for two hours
   B - Exposed only for four hours
   C - Exposed only for six hours

  Data Summary (**estimated):

  D1
  
    A - 0 inches
    B - 0 inches
    C - 0 inches
     
  
  D7 
  
    A - 1 inch
    B - 1.9 inches
    C - 2.6 inches
    
     
  D14
  
    A - 2.3 inches
    B - 2.4 inches
    C - 3 inches 
  
  D21
  
    A - 2.7 inches 
    B - 2.9 inches
    C - 3.5 inches 

• Conclusion: The hypothesis is proven true.
• Knowledge Sharing ✔

Options

A. hypothesis format is wrong, too much constant variables, need another independent variable, no control setup

B. needs more dependent variables, wrong data recorded, wrong independent variable, wrong observation format (needs to be factual)

C. wrong independent variable, full understandable conclusion additionally needs a summary, no control setup

Answer 3

C. wrong independent variable, full understandable conclusion additionally needs a summary, no control setup

Question 7

What are the correct characteristics of a hypothesis stated below?

A. correct and dependable
B. heavily researched with enough information
C. specific and testable
D. always factual with additional prior knowledge

Answer 7

C. specific and testable

Question 8

What are the supposed variables present when stating your hypothesis?

“If________, then _______.”

A. Independent and controlled variable
B. Manipulated variable and observation
C. Responding/Dependent variable only
D. none of the above

Answer 8

D. none of the above
correct answer: IV and DV (independent/manipulated and dependent/responding)

“If (IV), then (DV).”

Question 9

What is the main purpose of the scientific method?

A. To get a good grade in my science test
B. Get reliable and fair results through objective and clearly presented experimentation and presentation
C. The steps ensure the proper order of performing an experiment, thus it acts as a guide special to professional scientists.
D. its fun

Answer 9

B. Get reliable and fair results through objective and clearly presented experimentation and presentation

Question 10

Steps of the scientific method (class based)

Answer 10

Observation/Identify Problem, Experimentation, Hypothesis, Conclusion, Knowledge Sharing

Question 11

True or False. There must only be one hypothesis in an experiment.

Answer 11

False (ex. Francesco Redi’s experiment that debunked the Spontaneous Generation Theory - he stated three hypothesis.)

Question 11

Inference or Observation. “The painting used a style of impressionism which emphasized the way light bathed the subjects.”

Answer 11

Observation

Question 12

One day, Toby the kitten wander into his owner’s laboratory. He saw multiple experimental setups of tomato plants across the long table alphabetically arranged from A-Z. Even though he is a cat, Toby enjoys investigating the control setups of each experiment his owner performs. What is the setup he would most likely approach first?

A. Setup T for Toby
B. Setup A
C. Setup Z
D. Setup D for don’t like dogs

Answer 12

Setup A (usually, the first setup is most likely the controlled)

Question 13

What is the variable that is being tested?

A. IV/Manipulated
B. Controlled Setup
C. DV/Responding
D. Experimental Setup

Answer 13

A. IV/Manipulated

Question 14

Identify the correct IV-DV variable relationship given the hypothesis.

A. 

Hypothesis: If the number of weeds increase, then amount of fruit produced will increase.

    IV - presence of weeds 
    DV - height growth 

B. 

Hypothesis: If the amount of water is increased, then the height of the plant will increase.

    IV - amount of water given 
    DV - type of fruit production

 C. 

Hypothesis: If the amount of study time increases for a year eight student, then they’re height will decrease.

    IV - amount of study time
    DV - grade
