Which of the following is an example of REPETITION?


A. Ride your bike from a start line drawn in sidewalk chalk to the stop sign and back as fast as you can. Try this three times, and take your average time.

B. Grow two seeds in your classroom. One seed is grown with sunlight, and the other without. Then, have a friend try the same experiment.

C. Go to the Everglades on a trip to watch and record the movement of several alligators.

D. Create a family tree that includes all of your family up to your great-grandparents.

Pick and explain one of the scientific laws or theories that we discussed in class.

(OR: Pick and explain a scientific law or theory that we did not discuss in class.)
Answers may vary. Some examples are:

Laws: Newton's 3 Laws of Motion, Kepler's Law of Planetary Motion, Law of Thermodynamics, Law of Gravity.

Theories: The Big Bang Theory, Evolution, Natural Selection

Look at the following model:


For my science project, I made a model of a human lung.

I used a shoebox to represent the outside of the lung. I used a tube for the trachea and glued it to the outside of the box. I used straws to represent the bronchi. I used toothpicks to represent the bronchioles.


What is a BENEFIT of using this model?

What is a LIMITATION of using this model?
Benefits- shows something that you can not see, larger representation of the lung, straws accurately represent the tube-like bronchi...

Limitations- not an actual lung, can not function as a lung, shoebox is square but a lung is not square, can not include all of the parts of the lung including the alveoli...

Which of the following is SUBJECTVE?

A. My apartment is on the second floor.
B. Plants that are watered daily grow to be very tall.
C. My dog has white fur.
D. My cat weighs twice as much as my dog.
Answer:

B. Plants that are watered daily grow to be very tall.


How tall is "very tall"? Since that is not a definite amount, that would be SUBJECTIVE

A- Analyze your results
B- Test your hypothesis.
C- Hypothesize (make a hypothesis).
D- Share your results in a peer-reviewed scientific journal.
E- Develop a conclusion.
F- Ask a question. Make an observation. Make an inference.
F- Ask a question. Make an observation. Make an inference.

Name one way that scientific knowledge has changed any time in history.

(Note: You may NOT use the heliocentric/geocentric example.)
Answers may vary. Some examples are:

Before the explorations of Christopher Columbus, people thought that the Earth was flat. We now know that the earth is spherical, or round.

Until several years ago, Pluto was considered to be one of the main planets in our solar system. We have since changed our thinking of Pluto. Pluto is now considered to be a "dwarf planet." (Note: Nothing physically changed about Pluto. The only thing that changed was our THINKING of Pluto.)

What is the difference between a scientific law and a scientific theory?
A scientific law is a phenomenon of nature that is DEFINITELY proven to be TRUE under a certain circumstance.

A scientific theory is an explanation for a scientific observation. It is backed by scientific evidence, but it is not DEFINITELY proven to be true without doubt.
500
Name an example of a conceptual model.
A conceptual scientific model is a model that you think in your mind (think: concept = topic or idea).
500
Name an example of an observation. Then, give an example of an inference made from your observation.
Answers may vary.

Example:

Observation: Luis ate three slices of cake at the birthday party.

Inference: Luis ate three slices of cake at the birthday party. Therefore, Luis must like cake.

Name the dependent and independent variables in this experiment. Then, name the control group. What should the conclusion be?

Ms. DelGenio designs an experiment to see if candy has an effect on the test grades of students. Here is her experiment and results:

Class Period----1------3------4------5-------6------7--
Candy Given---0-------1------2------3------4-------5--
% A on Test--70%--65%--60%--58%--55%--54%--
dependent variable- test scores

independent variable- amount of candy

control group- 1st period: the class with no candy

conclusion- Candy negatively affects test scores. Ms. DelGenio should not give her students candy on test day.
