Learning Programme 1 (LP1)
Subject: P7.1
Year group: 11
During this half term I will be learning …
LP2/1
Recall and explain the apparent motions of Sun and
Moon in terms of the rotation of the Earth and the orbits
of the
Earth and Moon
explain the phases of the Moon in terms of the relative
positions of the Sun, Moon, and Earth
explain why different stars are seen in the night sky at
different times of the year, in terms of the movement of
the
Earth round the Sun
H: explain why a sidereal day, a rotation of 360° of the
Earth, is different from a solar day due to the
orbital movement of the Earth and that a sidereal day is
4 minutes less than a solar day
LP2/2
explain that the positions of astronomical objects are
measured in terms of two angles as seen from Earth H:
explain how the angles relate to the celestial sphere
recall that the planets Mercury, Venus, Mars, Jupiter,
and Saturn can be seen with the naked eye
H: describe how the planets appear to move with the
stars but also to change their position relative to
the fixed stars
recall that, (H: and explain why), planets sometimes
appear to move with retrograde motion relative to the
‘fixed’ stars
LP2/3
• explain both solar and lunar eclipses in terms of the
positions of the Sun and Moon

Learning Programme 1 (LP1)
• H: explain the low frequency of eclipses in terms of
the relative tilt of the orbits of the Moon about the
Earth and the Earth about the Sun
• use the idea of angular size to measure how big an
object appears to an observer
• recall that stars and other astronomical objects emit
radiation across a wide range of wavelengths
• recall that some parts of the electromagnetic spectrum
are absorbed by the atmosphere much more than others
• recall that optical and infrared astronomical
observatories on Earth are mostly situated in Chile,
Hawaii, Australia,
and the Canary Islands
LP2.4
• recall that stars and other astronomical objects emit
radiation across a wide range of wavelengths
• recall that some parts of the electromagnetic spectrum
are absorbed by the atmosphere much more than others
• recall that optical and infrared astronomical
observatories on Earth are mostly situated in Chile,
Hawaii, Australia,
and the Canary Islands
• explain how an image can be formed on a screen using
a pinhole camera
• explain why the image formed with a converging lens is
brighter
LP2.5
• measure the focal length of a converging lens
• calculate the power of a lens from: power (D) = 1/focal
length (m)
• understand that a more powerful lens of the same
material has a more curved surface
• explain refraction in terms of the change in speed of a
wave
• explain how refraction leads to the formation of an
image by a converging lens
• draw and interpret ray diagrams for a converging lens
forming an image of a
distant object and for an extended distant object
LP2/6
• explain that astronomical objects are so distant that
light from them reaches the Earth as effectively parallel
sets of rays
• explain that a simple telescope has two converging
lenses of different powers, with the more powerful lens
as the eyepiece
• explain the function of the objective lens and the
eyepiece
• explain why most astronomical telescopes have
concave mirrors, not converging lenses, as their
objectives
• describe how concave mirrors bring a parallel beam of
Exam style questions

light to a focus
LP2/7
• explain how parallax makes closer stars seem to move
relative to more distant ones over the course of a year
so; a smaller parallax angle means that the star is
further away
• calculate distances in parsecs for simple parallax
angles expressed as fractions of a second of arc
• recall that a parsec is similar in magnitude to a
lightyear and is the unit used by astronomers to measure
distance and that typical interstellar distances are a few
parsecs
• recall that the luminosity of a star depends on its
temperature and its size
• explain why the observed intensity of light from a star
depends on both the star’s luminosity and its distance
from Earth.
