Move the red date indicator to about March 21 and move the observer standing on Earih. an observer's latitude of about $40^{?}\mathrm{N}$. Now record the Sun's Altitude on March 21 in Table , below. The red line at the observer's latitude can be used to estimate the Hours the Sun is $U_p$ by mating what percentage of the 24-hour day the observer will be in daylight and in darkness Earth rotates. Put another way, what fraction of the red line is in daylight and what fraction in darkness? Take the daylight fraction and multiply by 24 . This gives the estimated number hours of daylight for that date and latitude. Estimate the Hours the Sun is Up on March 21 fromer $40^{?}\mathrm{N}$ and record in Table 2.2 below. Use the red date indicator and move observer standing on Earth to repeat what you just did for all four latitudes and all four dates in Table 2.1 and Table 2.2 until all the entries in BOTH TABLES are filled out.
