Entry Task Tuesday, May 26th Schedule: • Seasons Notes What do you know about Earth in space? Write down as Objective: I can understand many things about Earth in that Earth rotates on a tilted Space as you can think of. axis and orbits the sun and how that causes day and night, seasons Homework: • Read/RSG 20.1 • 20.1 Vocabulary • Earth turns on its axis of rotation as it orbits the Sun. The axis of rotation is an imaginary line running through the center of Earth. •Sunlight shines on half of Earth at any given time, producing daytime due to the Earth’s rotation. • A season is a pattern of temperature changes and other weather trends over the course of a year. • The tilt of the Earth’s axis causes the seasons due to changes in the amount of sunlight which results in changes in temperature. Click the Earth! • Equinox – sunlight shines equally on the northern and southern hemispheres. • Solstice – the area of sunlight is at a maximum in one hemisphere and a minimum in the other hemisphere. • Half of the sunlight is in each hemisphere. • The strongest sunlight is on the equator. • Marks the beginning of fall in the Northern Hemisphere and spring in the Southern Hemisphere. • Less than half of the Northern Hemisphere is in sunlight. • The strongest sunlight is south of the equator, so the Southern Hemisphere grows warmer. • Marks the beginning of winter in the Northern Hemisphere and summer in the Southern Hemisphere. • Half of the sunlight is in each hemisphere. • The strongest sunlight is on the equator. • Marks the beginning of spring in the Northern Hemisphere and fall in the Southern Hemisphere. • Less than half of the Southern Hemisphere is in sunlight. • The strongest sunlight is north of the equator, so the Northern Hemisphere grows warmer. • Marks the beginning of summer in the Northern Hemisphere and winter in the Southern Hemisphere. • The angle of sunlight affects temperature. • Winter : Sun appears low in the sky (long shadows). • Spring and Fall: Sun appears higher in the sky (medium shadows). • Summer: Sun appears high in the sky (short shadows). • Day length affects temperature. • The longer the days = higher the temperature. • The shorter the days = lower the temperature. Entry Task Wednesday, May 27th Answer the following questions using full sentences, IQIA. 1. How long does it take Earth to turn once on its axis? 2. What is this motion called? 3. How long does it take Earth to move once around the sun? 4. What is this motion called? Schedule: • Bill Nye- Seasons • 20.3 Read/RSG Objective: • I can understand that Earth rotates on a tilted axis and orbits the sun which creates the seasons Homework: • 20.3 Vocabulary Please have on desk: • 20.1 RSG • 20.1 Vocabulary Entry Task Thursday, May 28th Answer the following questions, IQIA. 1. During which phase does the moon seem to disappear? 2. What happens to the moon during the first 2 weeks? 3. What becomes dark during a lunar eclipse? 4. What casts a shadow on Earth during a solar eclipse? 5. Why do tides occur? Schedule: Phases of the Moon Moon Phase and Eclipse short read Objective: I can understand that positions of the Sun and Moon affect Earth Homework: Complete Moon FlipBook Please have on desk: • 20.3 Vocabulary • A lunar phase is the pattern of lit and unlit portions of the Moon that you see from Earth. • The Moon takes 27.3 days to go through all the lunar phases. 1. The cycle begins with a NEW MOON. 2. WAXING CRESCENTS occur during the first week as sunlight falls on the near side of the Moon. 3. As more and more of the Moon's near side becomes sunlit, the Moon appears to grow from WAXING CRESCENT to FIRST QUARTER to WAXING GIBBOUS. 4. Once a FULL MOON is reached, it begins to shrink from FULL to WANING GIBBOUS. 5. As less and less of the near side is in sunlight, the Moon appears to shrink from WANING GIBBOUS to THIRD QUARTER to WANING CRESCENT and back to NEW. Click the Moon • An eclipse happens when the moon blocks the Sun or the Earth's shadow falls on the moon. • Umbra: like an umbrella, makes a dark shadow; means shadow. • Penumbra: a partial or lighter shadow. penumbra umbra • Occurs when the Earth's shadow falls on the moon. • Lunar eclipses occur, on average, about every six months. • Occurs when the moon blocks our view of the sun. This happens when the Moon is exactly between the Sun and the Earth. Entry Task Friday, May 29th What do you know about our solar system? Write down as many things as possible. Schedule: • Mr. Big Head • Pluto Objective: I can understand that planets orbit the sun at different distances in our solar system. Homework: • Read/RSG 21.1 Please have on desk: Moon FlipBook
