Grade 2 Science Alabama Standards

Plan and carry out investigations to compare, contrast, and classify various solid and liquid materials according to physical properties, including color and texture.

Use a variety of sources to provide evidence that Earth’s events can occur slowly or rapidly. Examples: erosion, melting of glaciers; earthquakes, volcanic eruptions

Evaluate multiple solutions designed to slow or prevent wind or water from changing the shape of Earth’s surface.

Conduct investigations to determine suitable uses of natural and manufactured materials based on their observable properties, including strength, flexibility, hardness, absorbency, and texture.

Demonstrate and explain how structures made from a small set of pieces can be disassembled and then reassembled as new and different structures.

Provide evidence that some changes in matter caused by heating or cooling can be reversed and some changes are irreversible.

Plan and carry out an investigation, using one variable at a time, to determine how each variable affects plant growth.

Design and construct models to simulate how animals disperse seeds or pollinate plants.

Obtain information to explain that there are many different kinds of living things that exist in habitats on land and in water.

Use models to distinguish between the shapes and kinds of land and water on Earth.

Obtain information to identify where water is found on Earth and determine whether it is a solid or a liquid.

Participate in investigations to describe and sort solid and liquid materials according to physical properties.

Participate in multimedia activities (i.e., reading and video) that show Earth events happening over the short term or long term (e.g., volcano, earthquake, erosion, glacier).

Participate in activities that model changes caused by Earth’s events (e.g., creating water barriers out of sticks, pebbles, etc., and/or using a fan to simulate wind/tornado).

Identify suitable uses of natural and manufactured materials based on their observable properties.

Participate in building and then disassembling structures to make new structures.

Predict changes to matter, reversible and irreversible, that may occur when matter is heated or cooled (e.g., heating or freezing water, boiling an egg, baking a cake).

Participate in investigations of the growth needs of plants (e.g., water, light, soil, air) over a period of time.

Recognize that most plants produce seeds, which can be transferred by animals to cause new plants to be planted in other areas.

Identify that there are many different kinds of living things that exist in habitats on land and in water.

Identify the physical features of Earth (e.g., mountains, valleys, rivers, lakes).

Identify places where water is found on Earth as a liquid (e.g., rivers, lakes, oceans) and as a solid (ice/glaciers).

Patterns: Patterns in the natural and human-designed world can be observed, used to describe phenomena, and used as evidence.

Cause and Effect: Mechanism and Prediction: Events have causes that generate observable patterns. Simple tests can be designed to gather evidence to support or refute students’ ideas about causes.

Scale, Proportion, and Quantity: Relative scales allow objects and events to be compared and described (e.g., bigger and smaller; hotter and colder; faster and slower). Standard units are used to measure length.

Systems and System Models: Objects and organisms can be described in terms of their parts. Systems in the natural and designed world have parts that work together.

Energy and Matter: Flows, Cycles, and Conservation: Objects may break into smaller pieces, be put together into larger pieces, or change shapes.

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

Stability and Change: Some things stay the same while other things change. Things may change slowly or rapidly.

Asking Questions and Defining Problems: s Formulating simple descriptive questions that can be tested.

Developing and Using Models: Using and developing models that represent concrete events or design solutions, including diagrams, drawings, physical replicas, dioramas, dramatizations, or storyboards.

Planning and Carrying Out Investigations: Designing and conducting simple investigations, based on fair tests, which provide data to support explanations or design solutions.

Analyzing and Interpreting Data: Collecting, recording, and sharing observations.

Using Mathematics and Computational Thinking: Recognizing ways that mathematics can be used to describe the natural and designed world(s).

Constructing Explanations and Designing Solutions: Using evidence and ideas in constructing evidence-based accounts of natural phenomena and designing solutions.

Engaging in Argument from Evidence: Comparing ideas and representations about the natural and designed world(s).

Obtaining, Evaluating, and Communicating Information: Using observations and texts to gather and communicate new information
