- Use information from several sources to provide evidence that Earth events can occur quickly or slowly.
- Examples of events and timescales could include volcanic explosions and earthquakes, which happen quickly, and erosion of rocks, which occurs slowly.
Disciplinary Core Ideas:
- The History of Planet Earth: Some events happen very quickly; others occur very slowly, over a time period much longer than one can observe. (LE.ESS1C.a)
- Defining and Delimiting Engineering Problems:Asking questions, making observations, and gathering information are helpful in thinking about problems. (ETS.LE.1A.b)
Science and Engineering Practices:
- Obtaining, evaluating, and communicating information: Obtaining, evaluating, and communicating information in K–2 builds on prior experiences and uses observations and texts to communicate new information.
• 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 and/or supporting a scientific claim.
- Stability and Change: Things may change slowly or rapidly.
