Before
After
7L.1
State how long a day, a month and a year is
Describe the motion of the Sun across the sky
Describe how the Earth moves around the sun
Explain why we get day and night, and years and leap years
Make predictions about time of day
7L.2
Describe how the temperature changes with the season
Describe how the number of hours of daylight changes with the season
Describe how the Earth is tilted on its axis
Explain how the tilt of the Earth's axis causes the seasons
Describe the apparent motion of the Sun across the sky in different seasons
Explain why the days in the summer have more hours of daylight
Use the idea of concentration of the Sun's rays to explain the seasonal variation
7L.3
Describe the difference between a star and a planet
Describe how we see planets and classify objects as luminous or not
Explain why stars appear to move across the night sky
Explain why we see phases of the Moon
Use the phases of the Moon to explain how long it takes for the Moon to orbit the Earth
7L.4
Describe how the size of the Moon compares with the size of the Sun
Sequence pictures and descriptions of a solar eclipse
Explain how the position of the Moon causes eclipses
Explain why we don't see solar eclipses more frequently
Explain why the Moon is still visible during a total lunar eclipse
Use primary sources to describe how a total solar eclipse appears from Earth
7L.5
Compare the sizes of different objects in space
Name the planets in the Solar System
Determine whether an object is a star or a planet by its motion
Use data about the planets to describe patterns and to compare them with each other
7L.
