Six Types of MC Science Questions Gary Carlin, CFN 603 917 -714 -7448 gcarlin@schools. nyc. gov

Analyzing the Test Questions • Six Types of Questions • Difficulty Level • Bloom’s Taxonomy (M/C): – A. Knowledge – B. Comprehension – C. Application

Six Types of Questions • 1. (Concept/Process) Def/Ex • 2. Sequence/Equation • 3. Explanation • 4. Result • 5. Pairing • 6. Proof/Just (Calc/Read/Infer)

Definition/Example 1 The transfer of genes from parents to their offspring is known as (1) differentiation (3) immunity (2) heredity (4) evolution 23 One biotic factor that affects consumers in an ocean ecosystem is • (1) number of autotrophs • (2) temperature variation • (3) salt content • (4) p. H of water

Definition/Example • 2 Which object forms by the contraction of a large sphere of gases causing the nuclear fusion of lighter elements into heavier elements? • (1) comet (3) star • (2) planet (4) moon • 21 Which process requires water to gain heat energy from the environment? • (1) evaporation (3) infiltration • (2) condensation (4) precipitation

Sequence 14 Which sequence represents the correct order of processes that result in the formation and development of an embryo? (1) meiosis → fertilization → mitosis (2) mitosis → fertilization → meiosis (3) fertilization → meiosis → mitosis (4) fertilization → mitosis → meiosis

Sequence • 30 According to the fossil record, which sequence correctly represents the evolution of life on Earth? • (1) fish → amphibians → mammals → soft-bodied organisms • (2) fish → soft-bodied organisms → mammals → amphibians • (3) soft-bodied organisms → amphibians → fish → mammals • (4) soft-bodied organisms → fish → amphibians → mammals

Explanation 21 All life depends on the availability of usable energy. This energy is released when • (1) organisms convert solar energy into the chemical energy found in food molecules • (2) respiration occurs in the cells of producers and high-energy molecules enter the atmosphere • (3) cells carry out the process of respiration • (4) animal cells synthesize starch and carbon dioxide

Explanation • 43 Which statement best explains why location A has a cooler climate than location B? • • (1) Location A has a longer duration of insolation each day. (2) Location A is influenced by a cold ocean current. (3) Location B is farther from the equator. (4) Location B has less intense insolation each day.

Result 27 Increased industrialization will most likely • (1) decrease available habitats • (2) increase environmental carrying capacity for native species • (3) increase the stability of ecosystems • (4) decrease global warming

Result • 42 Which event is caused by Earth’s revolution? • (1) the apparent shift in the path of a Foucault pendulum • (2) deflection of planetary winds to the right in the Northern Hemisphere • (3) the apparent rising and setting of the Sun • (4) different constellations observed in the night sky throughout the year

Pairing • 2 Damage to which structure will most directly disrupt water balance within a single-celled organism? • (1) ribosome (3) nucleus • (2) cell membrane (4) chloroplast • 19 Which hormones most directly influence the uterus during pregnancy? • (1) testosterone and insulin • (2) progesterone and testosterone • (3) estrogen and insulin • (4) progesterone and estrogen

Pairing • 11 When two tectonic plates collide, oceanic crust usually subducts beneath continental crust because oceanic crust is primarily composed of igneous rock that has • (1) low density and is mafic • (2) low density and is felsic • (3) high density and is mafic • (4) high density and is felsic

Proof - Justification 5 Which procedure would most likely provide valid results in a test to determine if drug A would be effective in treating cancer in white mice? • (1) injecting 1 m. L of drug A into 100 white mice with cancer • (2) injecting 1 m. L of drug A into 100 white mice with cancer and 0. 5 m. L of drug X into 100 white mice without cancer • (3) injecting 1 m. L of drug A into 100 white mice with cancer and 0. 5 m. L of drug X into another group of 100 white mice with cancer • (4) injecting 1 m. L of drug A into 100 white mice with cancer and 1 m. L of distilled water into another group of 100 white mice with cancer

Proof-Justification • 1 Evidence that the universe is expanding is best provided by the • (1) red shift in the light from distant galaxies • (2) change in the swing direction of a Foucault pendulum on Earth • (3) parallelism of Earth’s axis in orbit • (4) spiral shape of the Milky Way Galaxy
