Muskingum Valley ESC Standards-Based Science Course of Study GRADE 2 EARTH AND SPACE – SUN, MOON AND STARS Benchmarks ES.2.A Observe constant and changing patterns of objects in the day and night sky. Grade Level Indicators and Sub-Indicators a.2.1 Recognize that there are more stars in the sky than anyone can easily count. a.2.2 Observe and describe how the Sun, Moon and stars all appear to move slowly across the sky. Resources To access links, hold down control key (CTRL) and click on the picture. a.2.3 Observe and describe how the Moon appears a little different every day but looks nearly the same again about every four weeks. ---------------SI.2.A Ask a testable question. ------------------------------------e.2.1 Ask “how can I/we” questions. e.2.2 Ask “how do you know” questions (not “why” questions) in appropriate situations and attempt to give reasonable answers when others ask questions. e.2.3 Explore and pursue student-generated “how” questions. SI.2.C Gather and communicate information from careful observations and simple investigation through a variety of methods. e.2.6 Recognize that explanations are generated in response to observations, events and phenomena. Sub-Indicators: Create a model of the sun, moon and earth systems (e.g., using a globe/sphere and a light source, StarLab, etc.). Demonstrate how the earth revolves around the sun. Identify the sun as the brightest star and is located in the center of our solar system. Investigate and record the direction of a person’s shadow at different times during the day. Observe patterns that stars make in the night sky, i.e., constellations (e.g., using pictures, StarLab, etc.). Investigate what causes day and night and the changing seasons. a = Earth and Space; b = Life; c = Physical; d = Science and Technology; e = Scientific Inquiry; f = Scientific Ways of Knowing -----------------------To access links, hold down control key (CTRL) and click on the picture.
