Scientific Method
The scientific method always begins with what
A question
All organisms on earth require energy to live. Where does all energy on earth come from.
What is the Sun.
The factor that is measured or observed in an experiment
Dependent variable
All microscope have an ocular lens with a magnification of what??
10x
The Latin root for this word means knowledge what is this word.
Science
This is a logical explanation of an observation that is drawn from prior knowledge
Inference
A mama duck just hatched 6 new baby ducklings. Which characteristic of life does this represent?
What is reproduction?
The factor you want to test in an experiment (this effects other parts of the experiment)
Independent variable
What is the lowest objective on the microscope and what is its color
4x
Red Color
kilo means what when it come to measurements.
1000
A possible explanation about an observation that can be tested by scientific investigation is???
Hypothesis
When you look at a leaf and a sample of human skin, we see that they are both made of tiny "building blocks". What characteristic of life does this represent?
All living things must be organized. ("All living things are composed of cells?")
The factors in an experiment that remain unchanged and the same throughout the experiment.
Constant
This microscope uses light and a lens to enlarge an object what type of microscope is it.
Light Microscope
A truck is speeding down the road which characteristic of life would help you stay alive and get out of the way

Your mom has been recording your height and weight each year on your birthday. What characteristics of life does this show?
What is growth and development?
If carrots are eaten daily, then there will be an improvement in vision. Based on this hypothesis, What is the independent variable?
Carrots eaten
We use these types of microscope in class. They work by magnifying an object through an ocular lens and an objective lens.
Compound Microscope
A student studies three types of bread. He measures the time it takes to grow mold.
Tell me the independent and dependent viable
DV- mold growth
IV- type of bread
Explain the difference between a scientific theory and a scientific law
A scientific law is proven a theory explains a phenomena in life without solid proof(we believe a theory to be right on the other hand a law is always right.)
All things must maintain a stable environment. For humans, that means keeping our temperature at 98 degrees. What characteristic of life does this show.
What is homeostasis?
A student changes the number of hours he studies for a test to see how it affects his test score.
What is the dependent variable?
Test Score
Credit is given to him for making the first modern microscope
Anton Van Leeuwenhoek
A botanist wants to see how different colored light waves influence the growth of pea plants. She puts the same number of seeds into three identical pots with the same kind and amount of soil. She then gives them the same amount of water every three days for the length of the experiment. One pot is placed into a dark windowless closet. Another pot is left on the windowsill, and the third is placed under a lamp with a green bulb. She records the height of each plant every day for three months.
Name one constant from this experiment.
Seed type
Amount of water
# of days
