1.6 - Earth and Space Systems
The student will investigate and understand that there is a relationship between the sun and Earth. Key concepts include
a) the sun is the source of energy and light that warms the Earth's land, air, and water; and
- with guidance, conduct simple investigations to show how sunlight changes the temperature of land, air, and water. Bloom's Level: Apply
- design a structure to reduce the change in temperature that occurs in sunlight throughout the day. Bloom's Level: Apply
b) the sun’s relative position changes in the Earth's sky throughout the day.
- observe where the sun rises in the morning and sets in the evening. Describe the pattern. Bloom's Level: Analyze / Apply
- with guidance, conduct a simple investigation to show how the sunlight changes the temperature at different times during the day. Bloom's Level: Apply
- use observations of the sun to describe patterns that can be predicted. Bloom's Level: Understand/ Apply
The sun is a source of energy that provides light and warmth for Earth and can be seen in different locations of the sky throughout the day/
UNDERSTANDING THE STANDARD
- The sun is the primary source of energy for Earth.
- The sun provides Earth with light and heat energy.
- Energy from the sun warms the land, air, and water by transferring heat energy to the Earth.
- 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.
- Patterns of motion of the sun in the sky can be observed, described, and predicted.
- The sun's relative position in the morning is in the eastern sky and in the later afternoon is in the western sky.
· 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
- investigate the question, "How does sunlight change the temperature of land, air, and water?"
- observe where the sun rises in the morning and sets in the evening.
- describe the pattern sun rise and sun set.
- investigate the question, "How does sunlight change the temperature at different times during the day?"
- design a structure to reduce the change in temperature that occurs in sunlight throughout the day.
- use observations of the sun to describe patterns that can be predicted
