Current selections are shown below (maximum of five)
clear Content Area: Science // Grade Level: Second Grade // Standard Category: 3. Earth and Space Science
Second Grade, Standard 3. Earth and Space Science
- 9. Students can use the full range of science and engineering practices to make sense of natural phenomena and solve problems that require understanding the universe and Earth's place in it.
1. Some events on Earth occur quickly; others can occur very slowly.
- Use information from several sources to provide evidence that Earth events can occur quickly or slowly. (2-ESS1-1) (Clarification Statement: Examples of events and timescales could include volcanic explosions and earthquakes, which happen quickly, and erosion of rocks, which occurs slowly.)
- Make observations from several sources to construct an evidence-based account for natural phenomena. (Constructing Explanations and Designing Solutions) (Entrepreneurial: Critical thinking/Problem solving)
- Students can answer the question: How do people reconstruct and date events in the Earth's planetary history?
- ESS1:C The History of Planet Earth: Some events on Earth occur in cycles, like day and night, and others have a beginning and an end, like a volcanic eruption. Some events, like an earthquake, happen very quickly; others, such as the formation of the Grand Canyon, occur very slowly over a time period much longer than one can observe.
- 10. Students can use the full range of science and engineering practices to make sense of natural phenomena and solve problems that require understanding how and why Earth is constantly changing.
2. Wind and water can change the shape of the land; models can show the shape and these changes to the land.
- Compare multiple solutions designed to slow or prevent wind or water from changing the shape of the land. (2-ESS2-1) (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.)
- Develop a model to represent the shapes and kinds of land and bodies of water in an area. (2-ESS2-2) (Boundary Statement: Does not include quantitative scaling in models.)
- Obtain information to identify where water is found on Earth and that it can be solid or liquid. (ESS2-3)
- Compare multiple solutions to a problem. (Constructing Explanations and Designing Solutions) (Entrepreneurial: Inquiry/Analysis)
- Develop a model to represent patterns in the natural world. (Developing and Using Models) (Personal: Initiative/Self-direction)
- Obtain information using various texts, text features (e.g., headings, tables of contents, glossaries, electronic menus, icons), and other media that will be useful in answering a scientific question. (Obtaining, Evaluating, and Communicating Information) (Civic/Interpersonal: Communication)
- Students can answer the question: How and why is Earth constantly changing?
- ESS2:A Earth Materials and Systems: Wind and water can change the shape of the land. The resulting landforms, together with the materials on the land, provide homes for living things.
- ESS2:B Plate Tectonics and Large-Scale System Interactions: Rocks, soils, and sand are present in most areas where plants and animals live. There may also be rivers, streams, lakes and ponds. Maps show where things are located. One can map the shapes and kinds of land and water in any area.
- ESS2:C The Roles of Water in Earth's Surface Processes: Water is found in the ocean, rivers, lakes and ponds. Water exists as solid ice and in liquid form. It carries soil and rocks from one place to another and determines the variety of life forms that can live in a particular location.
- Patterns: Patterns in the natural world can be observed.
- Stability and Change: Things may change slowly or rapidly.
- Influence of Science, Engineering and Technology on Society and the Natural World: Developing and using technology has impacts on the natural world.
- Connections to Nature of Science: Science Addresses Questions About the Natural and Material World. Scientists study the natural and material world.
