Examples
9
SEP-MOD-M4: Use and/or develop a model of simple systems with uncertain and less predictable factors.
10
DCI-PS3.C-E2: Energy can be moved from place to place by moving objects or through sound, light, or electric currents.
11
CCC-SPQ-H5: Patterns observable at one scale may not be observable or exist at other scales.
12
ENG-INTER-P1: Science and engineering involve the use of tools to observe and measure things.
13
NOS-WAK-E2: Science is a way of knowing that is used by many people.
