The student knows and applies scientific concepts and principles to understand the properties, structures and changes in physical, earth/space, and living systems.

1.1.1 Understand simple properties of common natural and manufactured materials and objects.

§ Identify and describe a property of an object.
§ Sort common materials and objects using a simple property (e.g., texture, color, size, shape).
§ Sort common objects by multiple simple properties (e.g., texture and color; size and shape).

1.2.7 Understand that plants and animals have life cycles.
Observe and describe the life cycle of a plant or animal (e.g., describe the life cycle of a butterfly – egg, caterpillar or larva, cocoon, and butterfly or adult

EALR 2 – INQUIRY:
The student knows and applies the skills, and processes, and nature of scientific inquiry

2.1.1 Understand how to ask a question about objects, organisms and events in the environment.
Ask questions about objects, organisms and events based on observations of the natural world.

2.1.2 Understand how to plan and conduct simple investigations following all safety rules

§ Make observations about characteristics or properties.
§ Make predictions of the results of an investigation.
§ Plan and conduct an observational investigation that collects information about characteristics or properties.
§ Collect data using simple equipment and tools that extend the senses (e.g., magnifiers rulers, balances, scales, and thermometers).
§ Follow all safety rules during investigations.

2.1.3 Understand how to construct a reasonable explanation using evidence.

§ Categorize and order observational data from multiple trials.
§ Explain an event or phenomena using observations as evidence (e.g., shape, texture, size, weight, color, motion and/or other physical properties).

2.1.5 Understand how to record and report investigations, results, and explanations.

§ (K, 1, 2) Report observations of simple investigations using drawings and simple sentences.
§ (1, 2) Describe and or draw the materials used in the investigation (e.g., numbers, shapes, colors).
§ (K,1, 2) Report safety procedures used during the investigation.
§ (2) Report the process used and results of the investigation (e.g., verbal, visual, written, and/or mathematical formats).

2.2.1 Understand that all scientific observations are reported accurately even when the observations contradict expectations.

§ Record what is observed and explain how it was done accurately and honestly.
§ Keep records and explain that the records have not been changed even when they did not match initial expectations.

2.2.2 Understand that observations and measurement are used by scientists to describe the world.

§ Raise questions about the natural world and seek answers by making careful observations and trying things out.
§ Make observations and measurements about natural phenomena.

2.2.3 Understand that similar investigations may not produce similar results.
Observe the procedures of two similar investigations and explain that they produced different results.

2.2.5 Know that ideas in science change as new scientific evidence arises.
Know how scientific inquiry results in facts, unexpected findings, ideas, evidence, and explanations.
