MO Science Standards (Grade 2) | Free Standards Reference

📌 Defining and Delimiting Engineering Problems (ETS1.A) 1 standard

2.ETS1.A.1

Ask questions to define a problem to be solved

Ask questions, make observations, and gather information about a situation people want to change to define a simple problem that can be solved through the development of a new or improved object or tool.

📌 Developing Possible Solutions (ETS1.B) 1 standard

2.ETS1.B.1

Sketch or model a design solution

Develop a simple sketch, drawing, or physical model to illustrate how the shape of an object helps it function as needed to solve a given problem.

📌 Earth Materials and Systems (ESS2.A) 1 standard

2.ESS2.A.1

Compare solutions to slow land/water erosion

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

📌 Forces and Motion (PS2.A) 1 standard

2.PS2.A.1

Analyze how force or mass changes motion

Analyze data to determine how the motion of an object changed by an applied force or the mass of an object.

📌 Interdependent Relationships in Ecosystems (LS2.A) 2 standards

2.LS2.A.1

Investigate plant growth under altered conditions

Plan and conduct investigations on the growth of plants when growing conditions are altered (e.g., dark vs. light, water vs. no water).

2.LS2.A.2

Model how animals disperse seeds or pollinate

Develop a simple model that mimics the function of an animal in dispersing seeds or pollinating plants.

📌 Optimizing the Solution Process (ETS1.C) 1 standard

2.ETS1.C.1

Compare test data from two competing designs

Analyze data from tests of two objects designed to solve the same problem to compare the strengths and weaknesses of how each performs.

📌 Plate Tectonics and Large-Scale Systems (ESS2.B) 1 standard

2.ESS2.B.1

Model shapes of land and bodies of water

Develop a model to represent the shapes and kinds of land and bodies of water in an area.

📌 Structure and Properties of Matter (PS1.A) 2 standards

2.PS1.A.1

Classify materials by observable properties

Plan and conduct an investigation to describe and classify different kinds of materials by their observable properties. [Clarification Statement: Observations could include color, texture, hardness, and flexibility. Patterns could include the similar properties that different materials share.]

2.PS1.A.2

Analyze material properties suited to a purpose

Analyze data obtained from testing different materials to determine which materials have the properties that are best suited for an intended purpose. [Clarification Statement: Examples of properties could include, strength, flexibility, hardness, texture, and absorbency.]

📌 The History of Planet Earth (ESS1.C) 1 standard

2.ESS1.C.1

Show evidence Earth events occur quickly or slowly

Use information from several sources to provide evidence that Earth events can occur quickly or slowly. [Clarification Statement: Examples of events and timescales could include volcanic explosions and earthquakes, which happen quickly and erosion of rocks, which occurs slowly.]

📌 The Role of Water in Earth's Surface Processes (ESS2.C) 1 standard

2.ESS2.C.1

Identify where water is found on Earth

Obtain information to identify where water is found on Earth and that it can be solid or liquid.

📌 Wave Properties (PS4.A) 1 standard

2.PS4.A.1

Investigate how vibration changes create sound changes

Plan and conduct investigations to provide evidence that changes in vibration create change in sound.
