The Scientific Method
What is a hypothesis?
An educated guess, a testable prediction
What is dependent variable?
What you are measuring at the end/the results
What is the basic unit of all life?
Cells
Give an example of growth and development
Answers vary (ex. caterpillar turning into a butterfly, a puppy growing into a dog, etc)
What is the SI unit for distance or length?
meters
Why is conducting research before experimenting important?
To learn more about the topic to create a more educated hypothesis
To check and make sure no one has done the research/answered the question before
What is an independent variable?
What you are testing/changing
What is reproduction?
When an organism creates additional organisms
Give an example of an organism responding to the environment
Answers vary (ex. exiting the building when the smoke alarm goes off, a dog coming to you when you call its name, a plant growing towards the sun, etc)
What is the SI unit for mass?
grams or kilograms
What should scientists always do after drawing their conclusions from the experiment?
Report their results
What is a controlled variable?
What is being kept the same across all groups and trials
What is the genetic material all life must have?
DNA
Give an example of homeostasis:
Answers vary (ex. shivering when cold, sweating when hot, insulin release with high blood sugar, constriction of veins and arteries with low blood pressure, etc)
What is the SI unit for volume?
Liters or milliliters
What is the first step of the scientific method?
Observe/ask questions
What is an experimental group?
The group that gets the independent variable/what is being tested
Maintaining set internal conditions in the body
What is metabolism?
The sum of all the chemical reactions in an organism
The ability to gain and use energy
If you have 47 mL, how many L do you have?
0.047 L
What are the six steps of the scientific method?
Observe/Question, Research, Hypothesize, Experiment, Analyze Results/Draw Conclusions, Report Results
What is the control group?
The group that does not get the independent variable/what is being tested
Just used as a comparison for the experimental group
Give an example of an autotroph and a heterotroph
Autotroph: plants, photosynthetic bacteria
Heterotroph: animals, fungi, bacteria, protists
What are the seven characteristics of life, not including evolution?
Made of cells
Growth and development
Reproduction
Metabolism
Homeostasis
Response to the environment
DNA
If you have 1.52 km, how many cm do you have?
152,000 cm
