1.6 - Sun and Earth

The student will investigate and understand the basic relationships between the sun and Earth. Key concepts include

a)  the sun is the source of energy and light that warms the land, air, and water; and

  • infer that sunlight striking an object makes the object warmer. Bloom's Level:  Apply
  • conduct simple experiments to show how sunlight changes the temperature of land, air, and water.  Bloom's Level:  Apply

b)  the sun’s relative position in the morning is east and in the late afternoon is west.

  • interpret the relationship between the sun’s position in the sky and the general time of day. This includes the sun’s relative position in the morning (east), at noon, and in the late afternoon (west).   Bloom's Level:  Analyze / Apply

Adopted: 2010

BIG IDEAS

Conditions on Earth depend on the sun.


UNDERSTANDING THE STANDARD

  • The sun provides Earth with light (a form of radiant energy) and thermal energy.
  • By transferring thermal energy to Earth, Earth’s atmosphere and land are heated. Thermal energy may be transferred from one substance to another by three means: conduction, convection, and radiation.
  • The sun provides energy, which warms the land, air, and water on Earth.
  • The sun’s relative position in the morning is east and in the late afternoon is west.

ESSENTIALS

Essential Questions:

·  Why do we need the sun?

·  What happens when sunlight strikes an object?

·  How does the sun's position change during the day?


In order to meet this standard, it is expected that students will

  • infer that sunlight striking an object makes the object warmer.
  • conduct simple experiments to show how sunlight changes the temperature of land, air, and water.
  • interpret the relationship between the sun’s position in the sky and the general time of day. This includes the sun’s relative position in the morning (east), at noon, and in the late afternoon (west).
