Globe Model Number 1-10 in your Lab Section Skip Lines
1 Move the globe to the time right now (from underneath) and the correct date (tilt the earth). Explain why it is our winter, and it is summer in the Southern Hemisphere.
2 Do not move the globe. Why is the Southern Hemisphere going to have more daylight hours that the Northern Hemisphere?
3 Explain why it is nighttime in Russia.
4 Move the globe to the December 21 st. Identify Fairbanks, Alaska on the globe. Rotate the globe all-the-way around while watching Fairbanks. Explain why Fairbanks Alaska experience almost all darkness during winter months.
5 Identify Santa Cruz, Argentina on the globe. Rotate the globe all-the-way around. Why does Santa Cruz experience almost all daylight during this time.
6 Identify Macapa, Brazil on your globe. Rotate the globe all-the-way around. Then, change the date to June 21 st. Turn the globe all-the- way around again while monitoring Macapa, Brazil. Why does Macapa, Brazil receive about the same amount of sunlight (12 hours) per day whether it is summer or winter?
7 Why is June 21 st (Summer Solstice) the longest day of the year for the Northern Hemisphere?
8 Why is June 21 st (Winter Solstice) the longest day of the year for the Southern Hemisphere?
9 Change the date to March 21 st. Identify Dallas, Texas on the globe. Rotate the globe all-the-way around. March 21 st is our Spring Equinox. Why do we have exactly 12 hours of daylight and 12 hours of darkness during this time of the year?
10 If March 21 is Spring for us, then why is it Fall for the Southern Hemisphere?
