discover that a model of something is different from the real thing but can be used to study the real thing
use different types of models, such as graphs, sketches, diagrams, and maps, to represent various aspects of the real world
Earth spinning around once every 24 hours (rotation), resulting in day and night
Earth moving in a path around the Sun (revolution), resulting in one Earth year
the length of daylight and darkness varying with the seasons
weather changing from day to day and through the seasons
the appearance of the Moon changing as it moves in a path around Earth to complete a single cycle
second, minute, hour
The Sun and other stars appear to move in a recognizable pattern both daily and seasonally.
Weather is the condition of the outside air at a particular moment.
wind speed and direction
form and amount of precipitation
general sky conditions (cloudy, sunny, partly cloudy)
evaporation: changing of water (liquid) into water vapor (gas)
condensation: changing of water vapor (gas) into water (liquid)
precipitation: rain, sleet, snow, hail
runoff: water flowing on Earth s surface
groundwater: water that moves downward into the ground
interaction between air and water breaks down earth materials
pieces of earth material may be moved by air, water, wind, and gravity
pieces of earth material will settle or deposit on land or in the water in different places
soil is composed of broken-down pieces of living and nonliving earth material
Extreme natural events (floods, fires, earthquakes, volcanic eruptions, hurricanes, tornadoes, and other severe storms) may have positive or negative impacts on living things.
Matter takes up space and has mass. Two objects cannot occupy the same place at the same time.
Matter has properties (color, hardness, odor, sound, taste, etc.) that can be observed through the senses.
Objects have properties that can be observed, described, and/ or measured: length, width, volume, size, shape, mass or weight, temperature, texture, flexibility, reflective- ness of light.
Measurements can be made with standard metric units and nonstandard units. (Note: Exceptions to the metric system usage are found in meteorology.)
The material(s) an object is made up of determine some specific properties of the object (sink/ float, conductivity, magnetism). Properties can be observed or measured with tools such as hand lenses, metric rulers, thermometers, balances, magnets, circuit testers, and graduated cylinders.
Objects and/ or materials can be sorted or classified according to their properties.
temperature -hot or cold
lighting -shadows, color
moisture -wet or dry
solids have a definite shape and volume
liquids do not have a definite shape but have a definite volume
gases do not hold their shape or volume
Temperature can affect the state of matter of a substance.
Changes in the properties or materials of objects can be observed and described.
Animals need air, water, and food in order to live and thrive.
Plants require air, water, nutrients, and light in order to live and thrive.
Nonliving things do not live and thrive.
Nonliving things can be human-created or naturally occurring.
Living things grow, take in nutrients, breathe, reproduce, eliminate waste, and die.
All living things grow, take in nutrients, breathe, reproduce, and eliminate waste.
An organism s external physical features can enable it to carry out life functions in its particular environment.
Plants respond to changes in their environment. For example, the leaves of some green plants change position as the direction of light changes; the parts of some plants undergo seasonal changes that enable the plant to grow; seeds germinate, and leaves form and grow.
Animals respond to change in their environment, (e.g. , perspiration, heart rate, breathing rate, eye blinking, shivering, and salivating).
Senses can provide essential information (regarding danger, food, mates, etc.) to animals about their environment.
Some animals, including humans, move from place to place to meet their needs.
Particular animal characteristics are influenced by changing environmental conditions including: fat storage in winter, coat thickness in winter, camouflage, shedding of fur.
Some animal behaviors are influenced by environmental conditions. These behaviors may include: nest building, hibernating, hunting, migrating, and communicating.
The health, growth, and development of organisms are affected by environmental conditions such as the availability of food, air, water, space, shelter, heat, and sunlight.
Green plants are producers because they provide the basic food supply for them- selves and animals.
All animals depend on plants. Some animals (predators) eat other animals (prey).
Animals that eat plants for food may in turn become food for other animals. This sequence is called a food chain.
Decomposers are living things that play a vital role in recycling nutrients.
An organism s pattern of behavior is related to the nature of that organism s environment, including the kinds and numbers of other organisms present, the availability of food and other resources, and the physical characteristics of the environment.
When the environment changes, some plants and animals survive and reproduce, and others die or move to new locations.
Plants manufacture food by utilizing air, water, and energy from the Sun.
The Sun s energy is transferred on Earth from plants to animals through the food chain.
Heat energy from the Sun powers the water cycle (see Physical Science Key Idea 2).
Humans depend on their natural and constructed environments.
Over time humans have changed their environment by cultivating crops and raising animals, creating shelter, using energy, manufacturing goods, developing means of transportation, changing populations, and carrying out other activities.
Humans, as individuals or communities, change environments in ways that can be either helpful or harmful for themselves and other organisms.
