1 Where on Earth are the daily solar altitudes higher and lower than Endicott?

2 In your notebooks, write RELATIONSHIPS between variables we tested CAUSE FIRST EFFECT SECOND EVIDENCE As you increase the time the INCREASE light is TIME on, As you decrease the angle DECREASE from 90 ANGLE o to 30 o As you increase the angle INCREASE from 30 o ANGLE to 90 o As you move from the poles DECREASE to the equator LATITUDEat a lower latitude, As you move from the equator INCREASE to the LATITUDE poles at a higher latitude, You the temp. of TEMP the air.

3 WHICH RELATIONS ARE DIRECT? Which are INVERSE? CAUSE FIRST EFFECT SECOND EVIDENCE As you increase the time the light is on, As you decrease the angle from 90 o to 30 o As you increase the angle from 30 o to 90 o As you move from the poles to the equator at a lower latitude (decrease latitude), As you move from the equator to the poles at a higher latitude (increase latitude), You increase the temp. of the air. You decrease the maximum temp. of the air. You increase the rate of temp change. You increase the angle of insolation You decrease the maximum temp. of the air. Time 0 is lowest value Temp at T-0 = T-16 = 90 o angle max temp = 30 o angle max temp = 90 o angle rate = 30 o angle rate = COLDER at Poles (indirect) Warmer at Equator (direct) (inferred from temp and angle data) COLDER at Poles (indirect) Warmer at Equator (direct) (inferred from temp and angle data)

4 Before we get started, let s draw a picture in our notebooks to show us what the dome model used in the SUN s PATH LAB is trying to show us.

5 What does solar altitude and intensity look like in Endicott in 3-D and how does it compare to other places around the world?

6 Sun s Path Lab on the diagram you should be able to In the title, add ENDICOTT at LATITUDE 42 o N so you remember this is very specific data. Eventually we will branch out to other places on Earth! Label the celestial meridian and the zenith for the observer Label each path of the sun with the season name, range of starting dates, and whether it is a solstice or equinox. Label each solar noon with its maximum solar altitude angle. For each path, label sunrise, sunset, and solar noon and include an arrow for the direction it travels on that path. Then label the compass direction (azimuth and cardinal) for each if you are the observer in Endicott. For each path, list the day/night length. For each path label the locations of minimum (twice) and maximum solar intensity (once) during the day. Label the path with the maximum solar intensity and minimum solar intensity. For each season, draw in the observer s relative shadow length at solar noon in the correct direction

7 his model should make more sense now! APPARENT PATH OF SUN IN THE SKY IN THE NORTHERN HEMISPHERE OBSERVER

8

9 What did the lab graph show us about SOLAR ALTITUDE, DIAMETER, & DAY LENGTH relate to each other? YOUR GRAPHS are PROBABLY the easiest way to SEE the RELATIONSHIPS.

10 Let s create a tilted Earth Model Draw in and label equator, N. Pole, and S. Pole Draw in Tropic of Cancer (23.5 o N latitude) Draw in Tropic of Capricorn (23.5 o S latitude) Draw in Arctic Circle (66 o N latitude) Draw in Antarctic Circle (66 o S latitude)

11 How are SEASONS related to the angle of insolation?

12 Seasons affect temperatures on Earth because of the angle of insolation

13 During different seasons, locations on Earth receive sunlight at different angles

14

15 Where & when does sun reach zenith (90 o )? June solstice at Tropic of Cancer (23.5 o N). That s North Hemi summer Sept equinox at equator (0 o ). That s North Hemi fall Dec solstice at Tropic of Capricorn (23.5 o S). That s South Hemi summer. Mar equinox at equator (0 o ). That s North Hemi spring
