Performance Expectations

The performance expectations in second grade help students formulate answers to questions such as:

• How does land change and what are some things that cause it to change?
• What are the different kinds of land and bodies of water?
• How are materials similar and different from one another, and how do the properties of the materials relate to their use?
• What do plants need to grow?
• How many types of living things live in a place?”

Students are expected to develop an understanding of what plants need to grow and how plants depend on animals for seed dispersal and pollination. Students are also expected to compare the diversity of life in different habitats. An understanding of observable properties of materials is developed by students at this level through analysis and classification of different materials. Students are able to apply their understanding of the idea that wind and water can change the shape of the land to compare design solutions to slow or prevent such change. Students are able to use information and models to identify and represent the shapes and kinds of land and bodies of water in an area and where water is found on Earth.

Calculation Method for DCI

Disciplinary Core Ideas are larger groups of related Performance Expectations. So the Disciplinary Core Idea Grade is a calculation of all the related Performance Expectations. So click on the Performance Expectation name below each Disciplinary Core Idea to access the learning targets and proficiency scales for each Disciplinary Core Idea's related Performance Expectations.

Clarification Statement: Examples of events and timescales could include volcanic explosions and earthquakes, which happen quickly and erosion of rocks, which occurs slowly.
Disciplinary Core Ideas
ESS1.C: The History of Planet Earth -Some events happen very quickly; others occur very slowly, over a time period much longer than one can observe.

Clarification Statement: Examples of solutions could include different designs of dikes and windbreaks to hold back wind and water, and different designs for using shrubs, grass, and trees to hold back the land.
Disciplinary Core Ideas
ESS2.A: Earth Materials and Systems -Wind and water can change the shape of the land.
ETS1.C: Optimizing the Design Solution -Because there is always more than one possible solution to a problem, it is useful to compare and test designs.

ESS2.B: Plate Tectonics and Large-Scale System Interactions -Maps show where things are located. One can map the shapes and kinds of land and water in any area.
