Structure of the Grade 7 Science ISAT

ISAT Science testing in spring 2008 will consist of 80 items: 30 norm-referenced, as well as 50 criterion-referenced items. Th e 30 norm-referenced items are an abbreviated form of the Stanford 10 Science assessment, developed by Harcourt Assessment, Inc. Th e 50 criterion-referenced items were written by Illinois educators and pilot tested with Illinois students.

Item FormatAll 80 items will be in multiple-choice format. All items are aligned to the Illinois Science Assessment Framework, which defi nes the elements of the Illinois Learning Standards that are suitable for state testing.

Science SessionsAll standard time administration test sessions are a minimum of 45 minutes in length. Any student who is still actively engaged in testing when the 45 minutes have elapsed will be allowed up to an additional 10 minutes to complete that test session. More details about how to administer this extra time will appear in the ISAT Test Administration Manual. Th is policy does not aff ect students who already receive extended time as determined by their IEP.

Session 145 minutes

40 multiple-choice items(30 of these are an abbreviated form of the Stanford 10.)

Session 245 minutes

40 multiple-choice items(Some items will be pilot items.)

Cumulative KnowledgeISAT tests students on the knowledge and skills that they should have acquired by grade 4 and grade 7. Proper curriculum alignment can establish which assessment objectives are covered at each grade level so that by the spring of any given year, all objectives have been presented. It is not the sole responsibility of a 4th grade teacher or a 7th grade teacher to teach all of the assessment objectives contained within the framework.

Th e grade 4 ISAT will assess the grade 4 assessment objectives. Th e grade 7 ISAT will assess the grade 7 assessment objectives but may also include the assessment objectives from grade 4. Th e sample items within this booklet provide the reader with an opportunity to see the ISAT format and how the items align to the assessment framework.

Assessment Objective

10 C12.7.06 Understand that cells divide to increase their numbers, and the process of cell division called mitosis results in two daughter cells each with identical sets of chromosomes.

11 C

12.7.12 Understand that heredity is based on the probability of inheriting a given trait for which one or both of the parents carries a gene, and that this probability can be calculated given the genetic make-up of the parents with regard to that kind of trait (e.g., blue eyes) using a Punnett Square.

12 A12.4.07 Understand the concept of food chains and food webs and the related classifications of plants or animals (e.g., producers, decomposers, consumers, herbivores, carnivores).

13 B

12.4.47 Identify the order of planets from the sun, and know that the further planets take longer to go around the sun. Understand that all planets in our solar system revolve around the sun. Because Earth revolves around the sun, objects (e.g., stars, planets, constellations) in the sky appear to change position throughout the year. Know that it takes Earth 365 4

1 days to revolve around the sun.

14 A

12.4.10 Identify the basic classifications of animals based on how they interact with their environment [e.g., (a) Some animals are active in the daytime (diurnal), others in the night time (nocturnal). (b) Some animals have a body temperature that stays the same regardless of significant temperature changes in their immediate environment (warm blooded), others have a body temperature that rises and falls with the temperature changes of their environment (cold blooded). (c) Some animals are herbivores, others are carnivores].

15 C12.7.25 Understand that three important cycles for the survival of living things in Earth’s ecosystems are the carbon dioxide-oxygen cycle, the water cycle, and the nitrogen cycle.

16 B

12.7.26 Understand that the number of organisms an ecosystem can support depends on the resources available and abiotic factors (e.g., the quantity of light and water, the range of temperatures, soil composition). Know that given adequate biotic and abiotic resources and no disease or predators, populations can increase at rapid rates. Understand that lack of resources and other factors (e.g., predation, climate) limit the growth of populations in specific niches in the ecosystem.

17 B 12.7.28 Distinguish the various members of a food web and identify the order of dependence among these members.

18 D

12.4.15 Understand that an increase in temperature generally causes things to expand, and that a decrease in temperature generally causes things to contract. Understand that particles move more slowly in a solid than they do in a liquid or a gas.

19 A12.7.47 Identify the basic properties of acids and bases. Know the relationship between acids, bases, and indicators (e.g., blue litmus paper changes to red when placed in an acid).

20 B

12.7.49 Understand that energy appears in many forms, such as heat, light, sound, chemical, mechanical, solar, nuclear, and electromagnetic energy. Understand the basic characteristics of each of these kinds of energy. Understand the nature of kinetic and potential energy.

21 B

12.7.57 Understand that light travels at different speeds in different materials. Understand that this is why light refracts—or changes direction—namely because it goes from one material in which it moves at one speed into another material through which it moves at a different speed.

22 A 12.4.26 Identify the basic forces, such as friction, magnetism, and gravity. Identify which force is operative in a simple scenario.

23 D 12.4.26 Identify the basic forces, such as friction, magnetism, and gravity. Identify which force is operative in a simple scenario.

24 C12.7.67 Understand that the gravitational force between two bodies decreases as the bodies get farther apart from each other. Know that the gravitational force between two bodies decreases as their masses decrease.

25 C12.7.69 Distinguish between mass and weight. Know that the mass of a body remains the same regardless of where it is but that the weight of it depends on how strong the force of gravity is in its current location.

26 D 12.4.33 Understand that some rocks contain plant and animal fossils. Know how they were formed.

27 B

12.7.75 Understand that that there are strata (layers) in many places in the crust of the earth. Understand that the crust of the earth is mostly igneous/metamorphic, with a relatively thin veneer of sedimentary rock layers in many, but not all places. Understand the principle of superposition: in a layered sedimentary sequence, the oldest rocks are usually at the bottom.

Understand the principle of superposition: in a layered sedimentary sequence, the oldest rocks are usually at the bottom.

29 D

12.7.78 Understand that some changes in the solid earth can be described as the rock cycle: rocks at the earth’s surface weather, forming sediments that are buried, then compacted, heated, and often recrystalized into new rock. Eventually, those new rocks may be brought to the surface by the forces that drive plate motions, and thus the rock cycle continues. Identify the three basic kinds of rock. Igneous rock is the result of cooled magma; granite, pumice, and scoria are examples. Sedimentary rock is the result of fine particles from eroded rocks being re-deposited by water or wind; sandstone and limestone are examples. Metamorphic rock is the result of rocks being changed by high temperatures and/or pressures; marble is an example.
