Science - 2nd Grade
Printable Version (pdf)
Course Introduction
Introduction
Science is a way of knowing, a process for gaining knowledge and understanding of the natural world. The Science Core Curriculum places emphasis on understanding and using skills. Students should be active learners. It is not enough for students to read about science; they must do science. They should observe, inquire, question, formulate and test hypotheses, analyze data, report, and evaluate findings. The students, as scientists, should have hands–on, active experiences throughout the instruction of the science
curriculum.
The K‐2 Science Core describes what students should know and be able to do at the end of each of the K‐2 grade levels. It was developed, critiqued, piloted, and revised by a community of Utah science teachers, university science educators, and State Office of Education specialists. Core Standards are supported by material research on science literacy and essential learning standards. The core concepts included in the Standards are those that are central to a discipline of science (i.e. Earth and Space Science, Physical
Science, and Life Science), that are accessible to students starting in kindergarten, and have potential for sustained exploration
across grades K‐2 and beyond.
Literacy and Numeracy Connections
The K‐2 Science Core supports literacy and numeracy learning for all students. The Guidance section contains suggested strategies
that are connected to language arts and mathematical topics. These connections assist teachers with activities of reading, writing,
speaking, presenting, calculating, graphing, and measuring in their science teaching. Teachers may integrate these activities into
literacy or mathematics instructional blocks, facilitating not only the teaching of science in a full instructional schedule, but also
increasing the literacy learning of many students by including non‐fiction reading and writing in the literacy block. Science concepts
can be taught in tandem with literacy skills through reading, speaking, and writing while students are involved in the scientific
process. Mathematical understanding can also be enhanced by highlighting the application of mathematical concepts in scientific
settings, such as using measurement concepts to weigh rocks or measure plants to investigate change over time.
Organization
The K‐2 Core is arranged to help teachers organize and deliver instruction as follows:
Instructional Framework:
Describes how the core is organized to assist teachers in understanding and teaching scientific concepts through
process skills, utilizing big ideas, and making application to technology and society.
Standards:
Standard 1: Is the intended learning outcomes standard. It contains three objectives: Processes of Science,
Communication of Science, and the Nature of Science. Standard 1 is not a stand‐alone piece of learning, but is
designed to be integrated into the three content standards.
Standards 2, 3, and 4: Reflects the disciplines of science. These standards are consistent across all three grades.
Each standard is further explicated by objectives and indicators.
Standard 2 is Earth and Space Science
Standard 3 is Physical Science
Standard 4 is Life Science
Science Content by Standard: Shows the learning progressions inherent in the core. The charts are organized
by standard, each containing the objectives and indicators for each grade side by side.
Supplemental Materials: Includes a chart of supplemental materials for each objective within the core. The
supplemental materials are color coded by standard: Earth and Space Science is green, Physical Science is blue,
and Life Science is red. A guide for reading and using the materials with an explanation of each section of the
sheet appears in Appendix B.
Appendices:
Appendix A: The Big Ideas for each standard organized by grade level.
Appendix B: What Students Should Understand, Do, and Know
Appendix C: How to read the supplemental materials charts.
Appendix D: Note, explanations, and research base.
Appendix E: References used in the development of the core.
Core Standards of the Course
Standard 1
The Processes of Science, Communication of Science, and the Nature of Science. Students will be able to apply scientific processes, communicate scientific ideas effectively, and understand the nature of science.
Objective 1
Generating Evidence: Using the processes of scientific investigation (i.e. framing questions, designing investigations, conducting investigations, collecting data, drawing conclusions)
-
Framing questions: Observe using senses, create a hypothesis, and focus a question that can lead to an investigation.
-
Designing investigations: Consider reasons that support ideas, identify ways to gather information that could test ideas, design fair tests, share designs with peers for input and refinement.
-
Conducting investigations: Observe, manipulate, measure, describe.
-
Collecting data: Deciding what data to collect and how to organize, record, and manipulate the data.
-
Drawing conclusions: Analyzing data, making conclusions connected to the data or the evidence gathered, identifying limitations or conclusions, identifying future questions to investigate.
Objective 2
Communicating Science: Communicating effectively using science language and reasoning
-
Developing social interaction skills with peers.
-
Sharing ideas with peers.
-
Connecting ideas with reasons (evidence).
-
Using multiple methods of communicating reasons/evidence (verbal, charts, graphs).
Objective 3
Knowing in Science: Understanding the nature of science
-
Ideas are supported by reasons.
-
There are limits to ideas in science (i.e. what can be observed, measured, and verified).
-
Differences in conclusions are best settled through additional observations and investigations.
-
Communication of ideas in science is important for helping to check the reasons for ideas.
Standard 2
Earth and Space Science. Students will gain an understanding of Earth and Space Science through the study of earth materials, celestial movement, and weather.
Objective 1
Describe the characteristics of different rocks.
Supplemental Materials (pdf)
-
Explain how smaller rocks come from the breakage and weathering of larger rocks.
-
Describe rocks in terms of their parts (e.g. crystals, grains, cement).
-
Sort rocks based upon color, hardness, texture, layering, particle size and type (i.e. igneous, metamorphic, sedimentary).
Objective 2
Observe and record recognizable objects and patterns in the night sky.
Supplemental Materials (pdf)
-
Observe, describe, and record patterns in the appearance and apparent motion of the moon in the night sky.
-
Observe and describe the number, arrangement and color/brightness of stars in the night sky.
Objective 3
Observe, describe, and measure seasonal weather patterns and local variations.
Supplemental Materials (pdf)
-
Compare and contrast the seasonal weather patterns during the school year.
-
Analyze and interpret data such as temperatures in different locations and different times.
Standard 3
Physical Science. Students will gain an understanding of Physical Science through the study of the forces of motion and the properties of materials.
Objective 1
Communicate observations about falling objects.
Supplemental Materials (pdf)
-
Observe falling objects and identify things that prevent them from reaching the ground.
-
Communicate observations that similar objects of varying masses fall at the same rate.
Objective 2
Compare and contrast the differences in how different materials respond to change.
Supplemental Materials (pdf)
-
Model physical changes of various materials.
-
Investigate and provide evidence that matter is not destroyed or created through changes.
Standard 4
Life Science. Students will gain an understanding of Life Science through the study of changes in organisms over time and the nature of living things.
Objective 1
Tell how external features affect an animals’ ability to survive in its environment.
Supplemental Materials (pdf)
-
Compare and contrast the characteristics of living things in different habitats.
-
Develop, communicate, and justify an explanation as to why a habitat is or is not suitable for a specific organism.
-
Create possible explanations as to why some organisms no longer exist, but similar organisms are still alive today.
Objective 2
Identify basic needs of living things (plants and animals) and their abilities to meet their needs.
Supplemental Materials (pdf)
-
Communicate and justify how the physical characteristics of living things help them meet their basic needs.
-
