How Can We Predict When The Sky Will Be Dark?
How Can We Predict When The Sky Will Be Dark?
How Can We Predict When the Sky Will Be Dark? is part of Smithsonian Science for the Classroom, a curriculum series by the Smithsonian Science Education Center. It is designed to address a bundle of grade 1 earth and space science and physical science standards. In this module, students:
- Use observations of real and photographed objects as evidence to explain that a girl can see objects outside because light from the Sun is shining on them.
- Use sunrise and sunset data as well as data from text to identify times of the year when the sky will be dark.
- Explain observed phenomena of the Sun and the Moon using observations of the Sun and Moon’s position in the sky.
- Use a model Moon to explain that the Moon appears to change shape because we see different amounts of the part with light shining on it.
- Use observations to describe the effect of a light source on the visibility of objects to solve the problem of kids having to walk to school in the dark.
Below are digital resources that support teaching of this module.
