Iowa Core Statements
1. Understand and apply knowledge of the complementary nature of structure and function and the commonalities among
   organisms.

Living systems at all levels of organization demonstrate the complementary nature of structure and function. Important levels of    organization for
structure and function include cells, organs, tissues, organ systems, whole organisms, and ecosystems.

2. Understand and apply knowledge of interdependency of organisms, changes in environmental conditions, survival of
   individuals and species and the cycling of matter and energy in ecosystems.

All organisms must be able to obtain and use resources, grow, reproduce, and maintain stable internal conditions while living in a constantly
changing external environment.

Regulation of an organism’s internal environment involves sensing the internal environment and changing physiological activities to keep
conditions within the range required to survive.

Behavior is one kind of response an organism can make to an internal or environmental stimulus. A behavioral response requires coordination and
communication on many levels, including cells, organ systems, and whole organisms. Behavioral response is a set of actions determined in part by
heredity and in part from experience.

Species acquire many of their unique characteristics through biological adaptation which involves the selection of naturally occurring variations in
populations.

Biological adaptations include changes in structures, behaviors, or physiology that enhance survival and reproductive success in a particular
environment.

For ecosystems, the major source of energy is sunlight. Energy entering ecosystems as sunlight is transferred by producers into chemical energy
through photosynthesis. That energy then passes from organism to organism in food webs.

3. Understand and demonstrate knowledge of the social and personal implications of environmental issues.

Chapter 12 of the Iowa Administrative Code states that science instruction shall include conservation of natural resources; and environmental
awareness.

The number of organisms an ecosystem can support depends on the resources available and abiotic factors, such as quantity of light and water,
range of temperatures, and soil composition. Given adequate biotic and abiotic resources and no disease or predators, populations (including
humans) increase at rapid rates. Lack of resources and other factors, such as predation and climate, limit the growth of populations in specific
niches in the ecosystem.

4. Understand and apply knowledge of the structure and processes of the earth system and the processes that change the earth
   and its surface.

The solid earth consists of layers including a lithosphere; a hot, convecting mantle and a dense metallic core.

Tectonic plates constantly move at rates of centimeters per year in response to movements in the mantle. Major geological events, such as
earthquakes, volcanic eruptions, and mountain building, are results of these plate motions.

Land forms are the result of a combination of constructive and destructive forces. Constructive forces include crustal deformation, volcanic
eruption, and deposition of sediment, while destructive forces include weathering and erosion.

Some changes in the 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 re-crystallized into new rock. Eventually, those new rocks may be brought to the surface by the forces that drive
plate motions, and the rock cycle continues.

Soil consists of weathered rocks and decomposed organic matter from dead plants, animals, and bacteria. Soils are often found in layers, with each
having a different chemical composition and texture.

Living organisms have played many roles in the earth system, including affecting the composition of the atmosphere, producing some types of
rocks, and contributing to the weathering of rocks.

5. Understand and apply knowledge of the water cycle, including consideration of events that impact groundwater quality.

Water, which covers the majority of the earth’s surface, circulates through the crust, oceans, and atmosphere in what is known as the “water
cycle.” Water evaporates from the earth’s surface, rises and cools as it rises to higher elevations, condenses as rain or snow, and falls to the surface
where it collects in lakes, oceans, soil and in soil and rocks underground.

Water is a solvent. As it passes through the water cycle, especially as it moves on the earth’s surface and underground, it dissolves minerals and
gases and carries them to the oceans, rivers, and other surface water.

                                                                   DMPS 7th Grade Science Curriculum 2011
Natural and human forces can contribute to contamination of surface water and groundwater.

6. Understand and apply knowledge of earth history based on physical evidence.

The earth processes we see today including erosion, movement of tectonic plates, and changes in atmospheric composition are similar to those that
occurred in the past.

Earth history is also influenced by occasional catastrophes such as the impact of an asteroid or a comet.

Fossils provide important evidence of how life and environmental conditions have changed.

7. Understand and apply knowledge of elements, compounds, mixtures, and solutions based on the nature of their physical and
   chemical properties and physical and chemical changes and their relationship to the conservation of matter and energy.

A substance has characteristic properties, such as density, a boiling point, and solubility, all of which are independent of the amount of the sample.
A mixture of substances often can be separated into the original substances using one or more of the characteristic properties.

Substances react chemically in characteristic ways with other substances to form new substances (compounds) with different characteristic
properties. In chemical reactions, the total mass is conserved. Substances often are placed in categories or groups if they react in similar ways;
metals is an example of such a group.

Chemical elements do not break down during normal laboratory reactions involving such treatments as heating, exposure to electric current, or
reaction with acids. There are more than 100 known elements that combine in a multitude of ways to produce compounds, which account for the
living and nonliving substances that we encounter.


8. Understand and apply knowledge of forms of energy and energy transfer.

Energy is a property of many substances and is associated with heat, light, electricity, mechanical motion, sound, nuclei, and the nature of a
chemical. Energy is transferred in many ways.

Heat moves in predictable ways, flowing from warmer objects to cooler ones, until both reach the same temperature.

Light interacts with matter by transmission (including refraction), absorption, or scattering (including reflection). To see an object, light from that
object- emitted by or scattered from it- must enter the eye.

                                                                        DMPS 7th Grade Science Curriculum 2011
Electrical circuits provide a means of transferring electrical energy when heat, light, sound, and chemical changes are produced.

In most chemical and nuclear reactions, energy is transferred into or out of a system. Heat, light, mechanical motion, or electricity might all be
involved in such transfers.

The sun is a major source of energy for changes on the earth’s surface. The sun loses energy by emitting light. A tiny fraction of that light reaches
the earth, transferring energy form the sun to the earth. The sun’s energy arrives as light with a range of wavelengths, consisting of visible light,
infrared, and ultraviolet radiation.
