Next Generation Science Standards for Third Grade Science

NGSS.3-ESS. EARTH AND SPACE SCIENCE

3-ESS2. Earth’s Systems - Students who demonstrate understanding can:

3-ESS2-1. Represent data in tables and graphical displays to describe typical weather conditions expected during a particular season.
3-ESS2-2. Obtain and combine information to describe climates in different regions of the world.
3-ESS2.DCI. Disciplinary Core Ideas
ESS2.D: Weather and Climate
ESS2.D:1. Scientists record patterns of the weather across different times and areas so that they can make predictions about what kind of weather might happen next. (3-ESS2-1)ESS2.D:2. Climate describes a range of an area's typical weather conditions and the extent to which those conditions vary over years. (3-ESS2-2)

3-ESS3. Earth and Human Activity - Students who demonstrate understanding can:

3-ESS3.DCI. Disciplinary Core Ideas
ESS3.B: Natural Hazards
ESS3.B:1. A variety of natural hazards result from natural processes. Humans cannot eliminate natural hazards but can take steps to reduce their impacts. (3-ESS3-1) (Note: This Disciplinary Core Idea is also addressed by 4-ESS3-2.)

NGSS.3-LS. LIFE SCIENCE

3-LS1. From Molecules to Organisms: Structures and Processes - Students who demonstrate understanding can:

3-LS1-1. Develop models to describe that organisms have unique and diverse life cycles but all have in common birth, growth, reproduction, and death.
3-LS1.DCI. Disciplinary Core Ideas
LS1.B: Growth and Development of Organisms
LS1.B:1. Reproduction is essential to the continued existence of every kind of organism. Plants and animals have unique and diverse life cycles. (3-LS1-1)

3-LS2. Ecosystems: Interactions, Energy, and Dynamics - Students who demonstrate understanding can:

3-LS2-1. Construct an argument that some animals form groups that help members survive.
3-LS2.DCI. Disciplinary Core Ideas
LS2.D: Social Interactions and Group Behavior
LS2.D:1. Being part of a group helps animals obtain food, defend themselves, and cope with changes. Groups may serve different functions and vary dramatically in size (Note:

3-LS4. Biological Evolution: Unity and Diversity - Students who demonstrate understanding can:

3-LS4-1. Analyze and interpret data from fossils to provide evidence of the organisms and the environments in which they lived long ago.
3-LS4.DCI. Disciplinary Core Ideas
LS2.C: Ecosystem Dynamics, Functioning, and Resilience
LS2.C:1. When the environment changes in ways that affect a place’s physical characteristics, temperature, or availability of resources, some organisms survive and reproduce, others move to new locations, yet others move into the transformed environment, and some die. (secondary to 3-LS4-4)
LS4.A: Evidence of Common Ancestry and Diversity
LS4.A:2. Fossils provide evidence about the types of organisms that lived long ago and also about the nature of their environments. (3-LS4-1)
LS4.C: Adaptation
LS4.C:1. For any particular environment, some kinds of organisms survive well, some survive less well, and some cannot survive at all. (3-LS4-3)
LS4.D: Biodiversity and Humans
LS4.D:1. Populations live in a variety of habitats, and change in those habitats affects the organisms living there. (3-LS4-4)

NGSS.3-PS. PHYSICAL SCIENCE

3-PS2. Motion and Stability: Forces and Interactions - Students who demonstrate understanding can:

3-PS2-2. Make observations and/or measurements of an object’s motion to provide evidence that a pattern can be used to predict future motion.
3-PS2-4. Define a simple design problem that can be solved by applying scientific ideas about magnets.
3-PS2.DCI. Disciplinary Core Ideas
PS2.A: Forces and Motion
PS2.A:1. Each force acts on one particular object and has both strength and a direction. An object at rest typically has multiple forces acting on it, but they add to give zero net force on the object. Forces that do not sum to zero can cause changes in the object’s speed or direction of motion. (Boundary: Qualitative and conceptual, but not quantitative addition of forces are used at this level.) (3-PS2-1)PS2.A:2. The patterns of an object’s motion in various situations can be observed and measured; when that past motion exhibits a regular pattern, future motion can be predicted from it. (Boundary: Technical terms, such as magnitude, velocity, momentum, and vector quantity, are not introduced at this level, but the concept that some quantities need both size and direction to be described is developed.) (3-PS2-2)
PS2.B: Types of Interactions
PS2.B:1. Objects in contact exert forces on each other. (3-PS2-1)
