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.
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.
Some traits of living things have been inherited (e.g., color of flowers and number of limbs of animals).
Some characteristics result from an individual s interactions with the environment and cannot be inherited by the next generation (e.g., having scars; riding a bicycle).
Plants and animals closely resemble their parents and other individuals in their species.
Plants and animals can transfer specific traits to their offspring when they reproduce.
Plants and animals have life cycles. These may include beginning of a life, development into an adult, reproduction as an adult, and eventually death.
Each kind of plant goes through its own stages of growth and development that may include seed, young plant, and mature plant.
The length of time from beginning of development to death of the plant is called its life span.
Life cycles of some plants include changes from seed to mature plant.
Each generation of animals goes through changes in form from young to adult. This completed sequence of changes in form is called a life cycle. Some insects change from egg to larva to pupa to adult.
Each kind of animal goes through its own stages of growth and development during its life span.
The length of time from an animal s birth to its death is called its life span. Life spans of different animals vary.
Growth is the process by which plants and animals increase in size.
Food supplies the energy and materials necessary for growth and repair.
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.
Humans need a variety of healthy foods, exercise, and rest in order to grow and maintain good health.
Good health habits include hand washing and personal cleanliness; avoiding harmful substances (including alcohol, tobacco, illicit drugs) ; eating a balanced diet; engaging in regular exercise.
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.
