What happens if you push or pull an object harder?
- Pushes and pulls have different strengths and directions
- Pushes and pulls start, stop, change speed or direction of an object*
How do equal and unequal forces on an object affect the object?
How can magnets be used?
- Objects have multiple forces acting on them (including gravity)
- Objects in contact exert forces on each other
- Balanced (no change) and unbalanced (change)
- Forces have strength and direction
- Patterns of objects in motion can be observed, measured and if regular used to predict
- Electric and magnetic forces between a pair of objects that do not touch*
Where do animals live and why do they live there?
- Animals need food, plants need water and light to live and grow
- Living things need water, air, and resources from their environment
- Plants and animals can change their environment
What do plants need to grow?
How many types of living things live in a place?
- Plants need water and light to grow and animals to pollinate or move their seeds*
- Match animals and plants to particular habitats
How are plants, animals, and environments of the past similar or different from current plants, animals, and environments?
What happens to organisms when their environment changes?
- Habitat changes: effects on plants and animals including none, adaptations, migration and death*
- Animal societies: sizes and benefits
- Fossils: timeline of plants, animals and habitats
Where does the energy in food come from and what is it used for?
How does matter cycle through ecosystems?
- Photosynthesis: the energy in food started as energy from the sun
- Food provides material for growth & repair and energy for motion and to maintain warmth in animals
- Food web in balanced and unbalanced ecosystems
- Cycle of matter in ecosystems
How does land change and what are some things that cause it to change?
What are the different kinds of land and bodies of water?
- Wind and water can change the shape of the land*
- Changes can be quick or take so long they cannot be observed
- Maps can show water and land formations
- Water is found in different bodies of water and in different states
How can water, ice, wind and vegetation change the land?
What patterns of Earth's features can be determined with the use of maps?
- Natural hazards: patterns, locations and effects and how people deal with them (earth quakes, volcanoes, tsunamis, etc.)*
- Rock formations/layers show history of earth's forces; fossils date the timeline
- Effects of water, wind, ice, living organisms and gravity on the Earth
How much and what kind of water can be found in different places on Earth?
- Earth's systems: define all, explore interactions between sets of two systems at a time (geosphere, hydrosphere, atmosphere and biosphere)
- Location, amount, type and form of all Earth's water
- How people protect Earth's resources and environments
What objects are in the sky and how do they seem to move?
- Patterns of the sun, moon and stars movement in the sky can be observed, described and predicted
- Seasonal patterns of sunrise and sunset can be observed, described and predicted (i.e. amount of daylight)
How do lengths and directions of shadows or relative lengths of day and night change from day to day?
How does the appearance of some stars change in different seasons?
- Evidence that gravity pulls objects down (toward the center of the Earth)
- Stars vary in distance from the earth and the intensity of their light is a function solely of that distance (at this grade level)
- Earth, moon and sun's role in the patterns and causes of day, night and length and direction of shadows
- Patterns of changing positions of sun, moon and stars in the sky over different time spans (within a day, month and year)
How are materials similar and different from one another, and how do the properties of the materials relate to their use?
- Matter has different properties and states (dependent on temperature)
- Different properties of matter are suited to different purposes*
- Matter can be rearranged
- Changes made to matter by heating or cooling cannot always be reversed
Can new substances be created by combining other substances?
When matter changes, does its weight change?
- Matter can exist in particles too small to see and moves freely in space
- Chemical changes/reactions
- Conservation of mass/weight with chemical, state, etc. changes
What happens when materials vibrate?
What happens when there is no light?
- Matter must vibrate to make sound
- Light is needed to see
- Light can pass some materials, be blocked by others or redirected by mirrors
- Light and sound can be used for communication*
What are waves and what are some things they can do?
- Waves in water – their patterns including amplitude and wavelength and effects on motion of objects
- Waves (can be digitalized, etc.) sent over distances (can then be converted) for use (information and entertainment)*
What is energy and how is it related to motion?
How is energy transferred?
How can energy be used to solve a problem?
- Define energy including stored energy
- Energy transfer and its products
- Connect energy and forces
- Electrical currents how they are produced and used*
- Energy's tie to renewable and nonrenewable sources including environmental impact
What is the weather like today and how is it different from yesterday?
- Weather is a combination of sunlight, precipitation and temperature at a particular time and place
- Sunlight warms the Earth's surface and everything on it*
- Types of severe weather are regional specific
What is typical weather in different parts of the world and during different times of the year?
How can the impact of weather-related hazards be reduced?
- Weather patterns across time and regions (patterns of change can be used to make predictions)
- Climate defined
- Severe weather and how humans can prepare for it*
What are some ways plants and animals meet their needs so that they can survive and grow?
How are parents and their children similar and different?
- Plants and animals have parts that help them to survive and grow*
- Some animals' parents take care of them
- Animals and plants are very similar but not exactly the same as their parents
How do internal and external structures support the survival, growth, behavior, and reproduction of plants and animals?
- Vision and reflected light from objects
- Visible (macroscopic) external and internal structures and their functions in plants and animals as they relate to growth, survival, behavior and reproduction
- Receiving, processing and responding the sensory information
How do organisms vary in their traits?
- Life cycles: plant and animal including reproduction
- Inheritance and environment impacts: cause the characteristics/traits and functions of each new generation including natural selection in species
