This is a book about the importance of the Sun's energy as it relates to its impact on the Earth’s environment. Learners will read or listen to a story about a young boy, Joshua, who finds out that the Sun provides the Earth with energy in the... (View More) form of light and heat, which is necessary for all forms of life, for maintaining Earth's environment, and for allowing humans to produce their own forms of energy. Additionally, an extension activity is included, Searching for the Sun, where learners can conduct a hands-on experiment observing how plants grow towards sunlight in order to make conclusions about why the Sun’s energy is a necessary component for life. Reading and vocabulary activities are also included. (View Less)

This is a book about seasons. Learners will read or listen to a story about two twins, Matt and Matilda, who are tasked with creating a model of the Earth-Sun system for a science fair project. Through some wild seasonal changes they experience... (View More) while creating the model, the two come to a better understanding of the causes of Earth's seasons. An extension activity is included (Reasons for the Seasons), as well as reading and vocabulary activities. (View Less)

This is an activity about how the Sun can affect the Earth's atmosphere, specifically the ionosphere. Learners will use real data from a Sudden Ionosphere Disturbance Monitor, or SID Monitor, to identify the signatures in the graphed data that can... (View More) be used to determine the times of sunrise and sunset. Although the SID monitors are designed to detect SIDs caused by solar flares, they also detect the normal influence of solar X-rays and UV light during the day as well as cosmic rays at nighttime. There is a distinct shape to a 24-hour SID data graph, with unique shapes, or signatures, of the graph appearing at sunrise and sunset.This activity is part of the Research with Space Weather Monitor Data educators guide. Use of and access to a Stanford Solar Center SID monitor and the internet is encouraged but not required. Locations without a SID monitor can use sample data provided in the educators guide.

This is an activity about the electromagnetic spectrum and how light is split into its component frequencies or colors. Using a diffraction grating, learners will observe four different light sources and sketch their spectra. This activity requires... (View More) access to a sodium vapor or mercury vapor light and two neon signs of differing color, as well as diffraction grating material. This is Astronomy Activity 2 in the Space Update collection of activities. (View Less)
