(1) Scientific processes. The student conducts classroom and field investigations following home and school safety procedures.

The student is expected to:

(A) demonstrate safe practices during classroom and field investigations

(B) learn how to use and conserve resources and dispose of materials.

(2) Scientific processes. The student develops abilities necessary to do scientific inquiry in the field and the classroom.

The student is expected to:

EOW-82. Science Fair Panic, part 1 - scientific method, science fair projects
EOW-82. Science Fair Panic, part 2 - scientific method, science fair projects
EOW-82. Science Fair Panic, part 3 - scientific method, science fair projects
EOW-82. Science Fair Panic, part 4 - scientific method, science fair projects
EOW-86. The Hottest Part of a Flame - scientific observation, combustion, energy

(A) ask questions about organisms, objects, and events

(B) plan and conduct simple descriptive investigations
EOW-43. Candles in a Jar and 44. Candles in a Jar, Part 2 - combustion, density, scientific thought
EOW-47. Bottle Tones and 48. Bottle Tones, Part 2 - pitch, vibration, scientific thought

(C) compare results of investigations with what students and scientists know about the world

(D) gather information using simple equipment and tools to extend the senses

(E) construct reasonable explanations and draw conclusions using information and prior knowledge

(F) communicate explanations about investigations.

(3) Scientific processes. The student knows that information and critical thinking are used in making decisions.

The student is expected to:

(A) make decisions using information

(B) discuss and justify the merits of decisions

(C) explain a problem in his/her own words and identify a task and solution related to the problem.

(4) Scientific processes. The student uses age-appropriate tools and models to verify that organisms and objects and parts of organisms and objects can be observed, described, and measured.

The student is expected to:

(A) collect information using tools including rulers, meter sticks, measuring cups, clocks, hand lenses, computers, thermometers, and balances
EOW-55. Light as Air - gases, density, math, volume
EOW-40. Reaction Time - nervous system, science fair projects

(B) measure and compare organisms and objects and parts of organisms and objects, using standard and non-standard units.
EOW-49. Measuring in Feet - human body proportions, crime science

(5) Science concepts. The student knows that organisms, objects, and events have properties and patterns.

The student is expected to:

(A) classify and sequence organisms, objects, and events based on properties and patterns

(B) identify, predict, replicate, and create patterns including those seen in charts, graphs, and numbers.

(6) Science concepts. The student knows that systems have parts and are composed of organisms and objects.

The student is expected to:

(A) manipulate, predict, and identify parts that, when separated from the whole, may result in the part or the whole not working, such as flashlights without batteries and plants without leaves

(B) manipulate, predict, and identify parts that, when put together, can do things they cannot do by themselves, such as a guitar and guitar strings

(C) observe and record the functions of plant parts
EOW-12. Seed Search - seed dispersal
EOW-64. Heartless Plants - plant anatomy

(D) observe and record the functions of animal parts.

(7) Science concepts. The student knows that many types of change occur.

The student is expected to:

(A) observe, measure, record, analyze, predict, and illustrate changes in size, mass, temperature, color, position, quantity, sound, and movement

(B) identify, predict, and test uses of heat to cause change such as melting and evaporation
EOW-5. Crushed Can - Atmospheric pressure, states of matter
EOW-29. Why We Sweat - energy, states of matter, evaporation

(C) demonstrate a change in the motion of an object by giving the object a push or a pull

(D) observe, measure, and record changes in weather, the night sky, and seasons.

(8) Science concepts. The student distinguishes between living organisms and nonliving objects.

The student is expected to:

(A) identify characteristics of living organisms

(B) identify characteristics of nonliving objects.

(9) Science concepts. The student knows that living organisms have basic needs.

The student is expected to:

(A) identify the external characteristics of different kinds of plants and animals that allow their needs to be met

(B) compare and give examples of the ways living organisms depend on each other and on their environments.
EOW-59. Nature Watching - animal behavior, processes of science

(10) Science concepts. The student knows that the natural world includes rocks, soil, water, and gases of the atmosphere.

The student is expected to:

(A) describe and illustrate the water cycle
BCIS-Water Cycle - states of matter, evaporation, condensation, weather

(B) identify uses of natural resources
