Content

Life Science:

Characteristics of Organisms

bulletIdentify distinguishing characteristics of animals.
bulletIdentify and classify animals based on shared characteristics.
bulletRecognize different sensory characteristics of animals.

Life Cycles and Heredity

bulletDescribe the basic life cycle of animals.
bulletIdentify the major stages in the life cycle(birth, growth, development, reproduction, and death).
bulletIdentify stages in the life cycle of the butterfly.
bulletExplain the metamorphosis of the butterfly
bulletCompare the life cycle of the butterfly to other animals.

Organisms and Their Environment.

bulletProvide examples of how inherited characteristics may change over time to enable the species to survive (e.g. shape of beak, shape of feet, placement of eyes).
bulletDescribe how plants use the sun’s energy to produce sugars by photosynthesis and these become part of the food chain.
bulletDescribe seashores/rainforests as habitats.
bulletDescribe the effects of human interaction on the rainforest and seashore.

Earth and Space Science:

Structure of the Earth System

bulletClassify types of rocks and minerals.
bulletIdentify minerals based on physical properties.
bulletDiscuss and demonstrate the tests to measure physical properties.
bulletExplain how soil is formed from the weathering of rocks and the decomposition of plant and animal remains.
bulletRelate precipitation, condensation, and evaporation to the water cycle.

Earth's History

bulletExplain the effects of severe weather on the surface of the earth (high winds, excessive amounts of rain/snow)

Earth in the Solar System

bulletDescribe the earth’s part in the solar system, which includes the sun, the planets, and their moons.
bulletIdentify the earth, sun, moon, and planets.
bulletDiscuss the earth’s revolution around the sun.
bulletRelate day/night to the earth's rotation.

Chemistry - Properties of Matter

bulletCollect data and compare (qualitatively and quantitatively) the size of objects (length and weight).
bulletDescribe how matter changes from one state to another.
bulletDiscuss and demonstrate the relationship of the phases of matter, using water as an example, and identify these phase changes (evaporation, condensation, etc.) by name.

Physics -- Energy

bulletIdentify various forms of heat/energy (include friction).
bulletExplain the effects of solar heat.
bulletDescribe the sources of energy/fuel.
bulletDemonstrate and describe the effect of magnetic poles.
bulletCompare the magnetic properties of objects and materials.
bulletIdentify characteristics of materials/objects that are attracted toward a magnet.

Technology and Engineering:

Materials and Tools

bulletIdentify materials needed to separate steel/ iron from other metals (magnets).
bulletDiscuss what is needed to construct a device to separate and lift paper clips from a mixture of paper clips and other non-magnetic materials.
bulletIdentify and discuss uses of simple machines such as incline planes, common levers, and common pulleys.
bulletExplain the difference between simple and complex machines.
bulletDiscuss how simple machines make work easier.

Science Applications

Identify a problem or design an opportunity.

Propose designs and choose between alternative solutions.

Implement a proposed solution.

Evaluate the solution and its proposed consequences.

Communicate the problem, process, and solution.

Science: Personal & Social Perspectives

Personal and community health.

Population growth.

Natural resources.

Environmental quality.

Natural- and Human-induced hazards.

History and Nature of Science

Science as Human Endeavor
Requiring reasoning, insight, energy, skill, and creativity, as well as habits of mind, i.e., intellectual honesty, tolerance of ambiguity, skepticism, and openness to new ideas.

Nature of Scientific Knowledge
Including evaluation of experiments, observations, theoretical models, proposed explanations, evidence, reasoning, and alternate conclusions.

Historical Perspectives
Including the study of famous scientists and discoveries.
