Title: The Riddle of the Russian Lights
In this Xpeditions student activity, students use maps to help an astronaut figure out why a string of lights zigzags across southern Russia. They examine maps depicting population density, average annual temperature, transportation density, and railroad networks to come up with the answer.
Standard(s): [S1] (6) 10: Describe components of the universe and their relationships to each other, including stars, planets and their moons, solar systems, and galaxies.
Title: Magnify It!
In this Science NetLinks lesson, students view objects of various sizes from several viewing distances to discover that their visual field is limited. Students record what they see and compare their observations with classmates in an open, nonjudgmental forum. They have the opportunity to speculate about and experiment freely with magnifying glasses and also conduct more structured experiments.
Standard(s): [S1] (5) 5: Contrast ways in which light rays are bent by concave and convex lenses.
Title: Modeling Shadows
In this Science NetLinks lesson, one of a four-part series on the sky, students construct models to demonstrate their understanding of shadows. The lesson uses the book Bear Shadow, by Frank Asch.
Standard(s): [S1] (2) 3: Recognize that light travels in a straight line until it strikes an object.
Title: The Warmth of the Sun
In this lesson from Science NetLinks, students take a closer look at the sun and begin to recognize its critical function in heating and warming the air, land, and water that sustain our lives. This involves drawing their attention to the basics of the heat around them and how the sun is the primary source of that warmth. They then perform a number of indoor and outdoor activities that help them begin to identify the sun as the natural, universal source of heat in the world.
Standard(s): [S1] (2) 11: Identify basic components of our solar system, including the sun, planets, and Earth's moon.
