Montana Standards for Second Grade Science

MT.S1. Students, through the inquiry process, demonstrate the ability to design, conduct, evaluate, and communicate results and reasonable conclusions of scientific investigations.

S1.1. Develop the abilities necessary to safely conduct scientific inquiry, including (a step-by-step sequence is not implied): (a) asking questions about objects, events, and organisms in the environment, (b) planning and conducting simple investigations

S1.1.gr2.D. Follow appropriate safety rules
S1.1.gr2.E. Follow step-by-step directions to conduct a simple guided investigation using controls and variables

S1.2. Select and use appropriate tools including technology to make measurements (including metric units) and represent results of basic scientific investigations

S1.2.gr2.A. Use tools to measure time, mass, volume, length, and temperature
S1.2.gr2.B. Record measurements
S1.2.gr2.C. Display measurement using graphs

S1.3. Use data to describe and communicate the results of scientific investigations

S1.3.gr2.B. Present data graphically
S1.3.gr2.C. Explain how the data addresses the scientific investigation question

MT.S2. Students, through the inquiry process, demonstrate the knowledge of properties, forms, changes and interactions of physical and chemical systems.

S2.1. Create mixtures and separate them based on different physical properties (e.g., salt and sand, iron filings and soil, oil and water)

S2.1.gr2.A. Create a mixture

S2.2. Examine, measure, describe compare and classify objects in terms of common physical properties

S2.2.gr2.A. List physical properties of common objects.
S2.2.gr2.B. Measure linear size of common objects
S2.2.gr2.C. Compare objects based on their similarities and differences.

S2.6. Identify, build, and describe mechanical systems and the forces acting within those systems

S2.6.gr2.A. Identify simple tools
S2.6.gr2.B. Explain how simple tools make work easier.

MT.S3. Students, through the inquiry process, demonstrate knowledge of characteristics, structures and function of living things, the process and diversity of life, and how living organisms interact with each other and their environment.

S3.3. Describe and use models that trace the life cycles of different plants and animals and discuss how they are differ from species to species

S3.3.gr2.A. Describe a plant life cycle (seed to plant to flower)
S3.3.gr2.B. Describe an animal life cycle
S3.3.gr2.C. Identify the stages of the life cycle (birth, growth, reproduction, death)
S3.3.gr2.D. Compare and contrast plant and animal life cycles.

S3.5. Create and use a classification system to group a variety of plants and animals according to their similarities and differences

S3.5.gr2.A. Use a simple classification system for plants and animals

MT.S4. Students, through the inquiry process, demonstrate knowledge of the composition, structures, processes and interactions of Earth's systems and other objects in space.

S4.1. Describe and give examples of earth's changing features

S4.1.gr2.A. Compare and contrast the characteristics of earth's natural features
S4.1.gr2.B. Make a model of a variety of earth's features (land and water)

S4.2. Describe and measure the physical properties of earth's basic materials (including soil, rocks, water and gases) and the resources they provide

S4.2.gr2.A. Identify that soil is made from rocks
S4.2.gr2.B. Identify that different rocks exist (color, texture)
S4.2.gr2.C. Compare and classify rocks based on color and texture.

S4.3. Investigate fossils and make inferences about life, the plants, animals, and the environment at that time

S4.3.gr2.A. Recognize that there are a variety of fossil types
S4.3.gr2.C. Define a fossil as physical evidence of past life.

S4.4. Observe and describe the water cycle and the local weather and demonstrate how weather conditions are measured

S4.4.gr2.A. Recognize that all types of precipitation are different forms of water
S4.4.gr2.B. Identify characteristics of different types of weather conditions

S4.5. Identify seasons and explain the difference between weather and climate

S4.5.gr2.A. List the four seasons
S4.5.gr2.B. Identify characteristics of each season
S4.5.gr2.C. Compare/contrast the seasons

MT.S5. Students, through the inquiry process, understand how scientific knowledge and technological developments impact communities, cultures and societies.
