Lab Simulation of Light Patterns

Mr. Paoro guides students through a lab simulation to understand how sunlight intensity varies across the Earth. Using an LED module to represent sunlight, students simulate and observe how light is distributed at different latitudes. The lab focuses on recording observations and analyzing data to understand the effects of latitude on sunlight distribution, specifically on December 22nd, the winter solstice. Students target various cities, sketch light patterns, and analyze the results to draw conclusions about sunlight intensity and its impact on temperature.

What does the LED module represent in the lab simulation?

• A solar eclipse

• A shadow on Earth

• A beam of sunlight

• The entire sun

What is the primary factor being adjusted in the lab to study sunlight intensity?

• Longitude

• Latitude

• Altitude

• Time of day

Why was December 22nd chosen for the lab measurements?

• It is the equinox

• It is the winter solstice

• It is the longest day of the year

• It is the summer solstice

Which city was the first to be observed in the lab simulation?

• Singapore

• Bellum, Brazil

• Oslo

• Atlanta

What is the significance of the light pattern observed at Oslo?

• It represents the equator

• It shows the end of the shadow

• It is the brightest spot on Earth

• It indicates light beyond the Earth's edge

What is the main focus when sketching the light pattern at Usua?

• The defracted light

• The LED body

• The main beam of light

• The shadow

How many different patches were created in the lab?

• Five

• Four

• Six

• Seven

What does the analysis of the lab data primarily focus on?

• The color of the light

• The temperature of the LED

• The speed of light

• The spread of light across different areas

In which city is the light pattern the most concentrated?

• Atlanta

• Usua

• Oslo

• Bellum, Brazil

What should students keep in mind about the triangles in the sketches?

• They are only for decoration

• They represent different times of the year

• They are equal in area

• They are different in size
