Grade 2: Save this Mountain!

Performance Expectations: Use information from several sources to provide evidence that Earth events can occur quickly or slowly.

Compare multiple solutions designed to slow or prevent wind or water from changing the shape of the land.




Science & Engineering Practices Disciplinary Core Ideas
Crosscutting Concepts
  • Developing and using models

  • Contructing explanations and designing solutions

  • Obtaining, evaluating and communicating information
  • The history of planet earth
    • Some events happen very quickly; others occur very slowly, over a time period much longer than one can observe.

  • Earth materials and systems
    • Wind and water can change the shape of the land

  • The role of water in Earth's surface processes
    • Water is found in the ocean, rivers, lakes, and ponds.

  • Optimizing the design solution
    • Because there is always more than one possible solution to a problem, it is useful to compare and test designs.
  • Patterns
    • Patterns in the natural and human designed world can be observed.

  • Systems and System Models
    • A system can be described in terms of its components and their interactions.

  • Cause and effect
    • Events have causes that generate observable patterns.

  • Stability and change
    • Things may change rapidly or slowly.
 




Grade 3: Engineering a Super Insect


Performance Expectations: Construct an argument that some animals form groups the help members survive.

Construct an argument with evidence that in a particular habitat some organizms can survive well, and some survive less well, and some cannot survive at all.



Science & Engineering Practices
Disciplinary Core Ideas
Crosscutting Concepts
  • Analyze and interpret data to make sense of phenomena using logical reasoning.

  • Construct an argument with evidence, data and/or a model.


  • Ecosystem Dynamics, Functioning, and Resilience

    • 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.

  • Social Interactions and Group Behavior

    • 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.

  • Adaptation

    • For any paricular environment, some kinds of organisms survive well, some survive less well, and some cannot survive at all.

  • Biodiversity and Humans

    • Populations live in a variety of habitats, and change in those habitats affects the organisms living there.

  • Cause and Effect
    • Cause and effect relationships are routinely identified, tested, and used to explain change.

  • Structure and Function
    • The shape and stability of structures of natural and designed objects are related to their function(s).

  • Scale, Proportion & Quantity
    • Natural objects and/or observable phenomena exist from the very small to the immensely large or from the very short to the very long time periods. 

  • Systems and System Models
    • A system can be described in terms of its components and their interactions.






Grade 4: Energizing Engineering!

Performance Expectations: Use evidence to construct an explanation relating the speed of an object to the energy of that object.

Apply scientific ideas to design, test, and refine a device that converts energy from one form to another.



Science & Engineering Practices
Disciplinary Core Ideas
Crosscutting Concepts
  • Asking questions and defining problems

  • Planning and carrying out investigations

  • Constructing explanations and designing solutions


  • Definitions of energy

    • The faster a given object is moving, the more energy it possesses.

  • Conservation of Energy and Energy Transfer

    • Energy is present whenever there are moving objects, sound, light or heat. When objects collide, energy can  be transferred from one object to another, thereby changing their motion. In such collisions, some energy is typically also transferred to the surrounding air, as a result , the air gets heated and sound is produced. 

  • Energy in Chemical Processes and Everyday Life

    • The expression "produce energy" typically refers to the conversion of stored energy into a desired form for practical use.

  • Defining Engineering Problems

    • Possible solutions to a problem are limited by available materials and resources (constraints). The success of a designed solution is determined by considering the desired features of a solution (criteria). Different proposals for solutions can be compared on the basis of how well each one meets the specified criteria for success of how well each takes the constraints into account.

  • Cause and Effect
    • Cause and effect relationships are routinely identified, tested, and used to explain change.

  • Energy and Matter
    • Objects may break into smaller pieces and be put together into larger pieces, or change shapes.

  • Systems and System Models
    • A system can be described in terms of its components and their interactions.
