Question 10The best scientists once believed that the Earth was flat, now it is believed

that the Earth is round; this is an example of science being:

A) empirically based

B) subjective

C) tentative

D) socially and culturally embedded

Question 10The correct answer is ‘C’Tentative means that it is subject to change.

Question 11Which of the following are considered abiotic factors in the

environment?

A) water

B) temperature

C) sunlight

D) ladybug

Question 11The correct answer is A, B, CAbiotic factors are non-living.

Question 12Bacteria breaks down a dead lion, this make the bacteria

which of the following?

A) heterotroph

B) decomposer

C) autotroph

D) tertiary consumer

Question 12The correct answer is ‘B’.A decomposer breaks down dead material.

Question 13The fact that science REQUIRES observation and data

shows that science is…A. tentativeB. empirically basedC. laws and theoriesD. socially and culturally embedded

Question 13B. empirically based means that it is based upon data

from observations

Question 14Which of the following is an example of quantitative data?

A) the room has 16 desks

B) the room is warm

C) there are 29 students in the room

D) the students in the room are smart

Question 14The answer is ‘A’ and ‘C’.Qualitative data deals with measurements and

numbers.

Question 15Which part of an experiment is the part that you change or

manipulate?

A) dependant variable

B) control group

C) hypothesis

D) independent variable

Question 15The answer is ‘D’.

Question 16All of the squirrels living in Chicagoland is an example of…

A) a community

B) an ecosystem

C) an organism

D) a population

Question 16The answer is ‘D’.A population is all the members of one species living in a

given area.

Question 17Why is a pyramid a good representation of the energy

structure in an ecosystem?

Question 17There is more energy at the bottom (producers) than the top since only

10% of the energy get transferred from one level to the next.

Question 18 An experiment is set up to determine which color light makes an aquatic plant

undergo photosynthesis the fastest. 4 different plants are placed under white, red,

blue, and green light while a 5th is placed in the dark. All oxygen produced by the

plant is captured and measured.

A) What is the independent variable?

B) What is the dependant variable?

C) What is the control group?

Question 18A) The independent variable is the thing that you manipulate-

color of light.

B) the dependant variable is the thing that you measure-

amount of oxygen produced

C) The control group is the group that does not have the

variable- the plant in the dark.

Question 19What cycle is the picture depicting?

Question 19The answer is the water cycle.

level to the next?

Question 2210%

Question 23What is the difference between an autotroph and a

heterotroph?

Question 23An autrotroph makes its own energy from sunlightA heterotroph must eat another organism to get energy

Question 24What is a hypothesis?

Question 24A proposed explanation that answers a question

Question 25Ideally, how many variables should be in an experiment?

Question 251

Question 28The sun

Question 29What is the difference between a food chain and a food

web?

Question 29A food chain show the energy path to one apex

consumer.A food web shows all the possible food chains in a given

ecosystem.
