Science
Sub Categories or Standards:
-
Measure using appropriate tools (e.g., ruler, scale, balance) and units of measure (i.e.., metric, U.S. customary).
-
Analyze data obtained in a scientific investigation to identify trends and form conclusions.
-
Analyze whether the data is consistent with the proposed explanation that motivated the investigation.
-
Identify how diverse people and/or cultures, past and present, have made important contributions to scientific innovations (e.g., Percy Lavon Julian [scientist], supports Strand 4; Niels Bohr [scientist], supports Strand 5; Edwin Hubble [scientist], supports Strand 6).
-
Provide examples that support the premise that science is an ongoing process that changes in response to new information and discoveries (e.g., space exploration, medical advances).
-
Describe how scientific knowledge is subject to modification and /or change as new information/technology challenges prevailing theories.
-
Describe changes of matter.
-
Describe the following forces: gravity and friction.
-
Describe the various effects forces can have on an object (e.g., cause motion, halt motion, change direction of motion, cause deformation).
-
Examine forces and motion through investigations using simple machines (e.g., wedge, plane, wheel and axle, pulley, lever).
-
Demonstrate effects of variables on an object's motion (e.g., incline angle, friction, applied forces).
