4th Grade Science Link

Life Science - Plants:

• Compare life cycles of different plants including germination, maturity, reproduction & death.
• Relate plant structures to their specific functions.
• Classify common plants according to their characteristics.
• Describe how organisms interact with one another in various ways.
• Observe & explore that fossils provide evidence about plants that lived long ago & the nature of the environment at that time.

Physical Science - Physical/Chemical Changes:

• Identify characteristics of a simple physical or chemical change.
• Describe objects by the properties of the materials from which they are made & that these properties can be used to separate or sort a group of objects.
• Explain that matter has different states & that each state has distinct physical properties.
• Compare ways the temperature of an object can be changed.

Earth Science - Weathering:

• Describe how wind, water & ice shape and reshape Earth's land surface by eroding rock and soil in some areas & depositing them in other areas producing characteristic landforms.
• Identify & describe how freezing, thawing & plant growth reshape the land surface by causing the weathering of rock.
• Describe evidence of changes on Earth's surface in terms of slow processes & rapid processes.

Earth Science - Weather:

• Explain that air surrounds us, takes up space, moves around us as wind, & may be measured using barometric pressure.
• Identify how water exists in the air in different forms.
• Investigate how water changes from one state to another.
• Describe weather by measureable quantities such as temperature, wind direction, wind speed, precipitation & barometric pressure.
• Record local weather information on a calendar or map & describe changes over a period of time.
• Trace how weather patterns generally move from west to east in the United States.
• Describe the weather which accompanies cumulus, cumulonimbus, cirrus & stratus clouds.
