Do Now 4/4 1.Copy down this week’s homework and leave out your planner to be stamped. 2.Grade SEM Complete your Moon Log for today. MondayTuesdayWednesdayThursdayFriday -No HW-SEM 4.3 #1-5-SEM 4.3 All-CFU for LT A tomorrow - Have a great break!

Minute to Win it! 1.As a table group use the iPad app “Planets” and click on “globe” to answer the following questions Where is one country that is experiencing night right now? What part of the Earth is experiencing sunrise right now?

SEM: Scientific Principles What causes the daily, monthly, and yearly patterns I see on Earth? SEM: Learning Targets SEM 2: The Earth is 4 times the diameter of the moon. The Sun is 109 times the diameter of the Earth. The Earth orbits the sun and the moon orbits the Earth. SEM 3: The Sun is higher in the sky in the summer and lower in the winter at solar noon. Shadows are long in the morning, shorter at solar noon, and long in the evening. SEM 4.1: The side of the Earth facing the sun is day and facing away is night. Seasons are caused by the tilt of the Earth relative to the Sun as it orbits the Sun. Equinox (fall and spring) is when the poles are equal distance from the sun and Solstice (winter and summer) is when one pole is pointed most towards the sun. SEM 4.2: The Earth rotates counter clockwise when viewed from the Northern Hemisphere. We know that the tilt of the Earth does not change through out the year because the North Pole always points towards Polaris.

Why do we have seasons? Possible ideas: A.The Earth is closer to the Sun in the Summer and further in the Winter. B.The tilt of the Earth changes through out the year. C.The side of the Earth facing the Sun will have the Sun lower in the sky. The side facing away from the Sun will have the sun higher in the sky. D.The Earth’s orbit around the Sun allows one pole to point more towards the sun and one pole more away from the sun at different points in the orbit.

RSQ #1 p101: On May 18, th Cairo, Egypt (30° N) has 14 Hours of day light. Google Earth, the classroom globe, or Map App, what city would have 10 hours of day light on May 18 th ? Explain. Cairo, Egypt 14 hrs daylight 10 hrs night30° N Unknown… 10 hrs daylight 14 hrs night30° S

Scientific Explanation Claim: A location at 30⁰ S would have 10 hours of day light on May 18 th. Evidence: If 30⁰ N has 14 hours of day light that means it has 10 hours of night. A place that has 10 hours of day light is the opposite so you are looking for a place on the opposite hempisphere. Reasoning: A location at 30⁰ S would have 10 hours of day light on may 18 th. This is because the Earth is tilted on its axis. On May 18 th the Northern Hemisphere is pointed more towards the Sun. This causes the Sun to be at a lower angle in the Southern Hemisphere causing shorter days and it is higher in the sky in the Northern Hemisphere causing longer days.

SEM 4.3 Graphing Your graph should show the apparent path of the sun across the sky for all four dates at your location. (Hint: How do the Spring and Fall Equinoxes compare?) Imagine that you are looking at your graph from this direction…Can you visualize how your data lines describe an arc across the sky?

EIS Describe the pattern of sunrise and sunset times for the equator? Why do you think this is so? The sunrise and sunset times do not change significantly through out the year. This is due to the fact that the Equator is always at the same angle to the Sun.

EIS How do sunrise and sunset times at the Antarctic compare to those in Alaska? They are almost opposite because they are far from the equator in opposite hemispheres. Alaska is not as extreme because it is closer to the equator than Antarctica is.

Summer on the North Pole

EIS How does the apparent path of the Sun across the sky during summer change as you move closer to the North Pole? The Sun is lower in the sky at solar noon as you move closer the North Pole in the summer.

Solar Noon - Equator

Solar Noon - Anchorage

Solar Noon - North Pole

EIS How might the apparent height of the Sun in the sky and the length of daylight affect the temperature for a particular latitude? The lower the Sun is in the sky the cooler the temperature. This is because the Sun’s rays have to travel through more atmosphere when it is lower in the sky thereby losing more energy. The shorter the length of daylight hours the cooler it is because the Sun has less time to warm up the surface of the Earth.

The tilt of the Earth causes the sunlight to come through the atmosphere at different angle

Picture from Earth in Space Textbook p55

Summer the sun is higher in the sky Winter the sun is lower in the sky

SEM: Scientific Principles What causes the daily, monthly, and yearly patterns I see on Earth? SEM: Learning Targets SEM 2: The Earth is 4 times the diameter of the moon. The Sun is 109 times the diameter of the Earth. The Earth orbits the sun and the moon orbits the Earth. SEM 3: The Sun is higher in the sky in the summer and lower in the winter at solar noon. Shadows are long in the morning, shorter at solar noon, and long in the evening. SEM 4.1: The side of the Earth facing the sun is day and facing away is night. Seasons are caused by the tilt of the Earth relative to the Sun as it orbits the Sun. Equinox (fall and spring) is when the poles are equal distance from the sun and Solstice (winter and summer) is when one pole is pointed most towards the sun. SEM 4.2: The Earth rotates counter clockwise when viewed from the Northern Hemisphere. We know that the tilt of the Earth does not change through out the year because the North Pole always points towards Polaris. SEM 4.3: The equator recieves 12 hours of day and 12 hours of night year round. As you move north in the summer the hours of day light get longer and the sun gets lower to the horizon causing less energy to reach the surface of the earth.

Why do we have seasons? Possible ideas: A.The Earth is closer to the Sun in the Summer and further in the Winter. B.The tilt of the Earth changes through out the year. C.The side of the Earth facing the Sun will have the Sun lower in the sky. The side facing away from the Sun will have the sun higher in the sky. D.The Earth’s orbit around the Sun allows one pole to point more towards the sun and one pole more away from the sun at different points in the orbit.

Why do we have seasons? Notes The Earth is tilted on its axis 23.5 degrees. As the Earth orbits the sun the Seasons change. When one pole is pointed most towards the sun it is summer (solstices). When the poles are equal distance from the sun it is fall and spring (equinox). During the summer the days are longer allowing the Earth to heat up more. During the summer the sun comes through the atmosphere at a more direct angle allowing more energy to reach the Earth.

Challenge Question Your friend is in Geneva Switzerland, 46 ○ N and 6 ○ E. What would the angle of separation be for your friend to see the North Star when they look into the night sky? The angle of separation = 46 ○

What’s up with the Moon? NewWaxing Crescent First Quarter Waxing Gibbous Full Waning Gibbous Third Quarter Waning Crescent New

So why do phases happen? 1.The Sun Angle Theory –As the Moon orbits, the angle the Sun hits it changes. This causes the Moon to light up more or less depending on the angle. 2.The Earth Shadow Theory –As the Moon orbits, the shadow of the Earth covers more or less of the Moon. 3.The Earth Perspective Theory –Where the Earth is relative to the Moon determines how much of the illuminated side you see.
