Mei measured the shadow of a ball using light sources of different widths. What do her results suggest about the shadow of the Moon?
The Sun is a tiny source, so the Moon has no penumbra
The width of the Sun makes no difference to the shadow
A wider Sun would make the Moon's umbra much wider
The Sun is a very wide source, so the Moon's penumbra is large
17.
Which method in the table is NOT safe?
A – eclipse glasses let through too much light
B – a pinhole image is far too bright to look at safely
C – sunglasses let through enough light to harm eyes

The Moon's umbra falling on Earth
Earth's own shadow on the clouds
A storm caused by the eclipse
The Sun's shadow on the ocean
24.
Why can a total lunar eclipse last over an hour, while total solar eclipses last only minutes?
The Moon moves much faster during a lunar eclipse than a solar one
The Sun moves across the sky faster at night than in the day
Earth's shadow is wider than the Moon, but the Moon's umbra on Earth is tiny
The Moon is closer to Earth during a lunar eclipse than a solar one
25.
Which sequence describes what is seen during a total lunar eclipse?
Whole Moon red → slight dimming → dark bite grows → bite shrinks
Dark bite grows → Moon vanishes → Sun appears → Moon returns
Slight dimming → Moon turns black → corona seen → Moon returns
Slight dimming → dark bite grows → whole Moon red → bite shrinks
26.
Ahmed found the edges of the shadow hard to see, so his umbra widths varied between measurements. What is the best improvement?
Use a brighter room so the edges of the shadow blend in
Darken the room and repeat each reading three times, then find the mean
Record only the largest width he measured each time
Move the lamp to a different place for each reading
27.
Which model best shows why a lunar eclipse can be seen from the whole night side of Earth?
Cover the globe's night side with figures; check which can see the ball in the shadow
Put one figure on the sunny side of the globe and shine the lamp straight at it
Move the ball between the lamp and the globe, then mark on the globe where the ball's shadow falls
Remove the lamp so that the whole globe and ball are in darkness
28.
A class model uses a 30 cm globe for Earth and a table-tennis ball 20 cm away as the Moon. What is the main weakness of this model?
The globe should be smaller than the Moon ball
The table-tennis ball is opaque, unlike the real Moon in space
The Moon is far too close compared with real distances
The lamp is a light source, unlike the real Sun
29.
Astronomers long ago noticed that the edge of Earth's shadow on the Moon is always curved, at every lunar eclipse. What does this suggest?
The Moon is flat, so shadows on it always look curved
Earth is flat, because its shadow never changes shape
The Sun is curved, so it makes curved shadows of anything
Earth is round, since only a sphere always casts a round shadow
30.

39.
If the Moon followed path R in the diagram, it would look only slightly dimmer, with no dark "bite" taken out of it. True or false?
Dr Dabour Hub Academy - figure 8
False – the Moon would turn completely dark copper-red
True – the penumbra blocks only part of the light
False – the Moon would vanish completely
True, but only because path R is at new moon
40.
The lowest reading on the graph is about 2%, not 0%. This supports the idea that Earth's atmosphere bends some sunlight into the umbra. True or false?
Dr Dabour Hub Academy - figure 9
False – it shows the Moon makes its own light
False – the Moon never enters the umbra
True, but the light comes from other stars

If the Moon's orbit were not tilted, there would be a solar eclipse at every new moon and a lunar eclipse at every full moon. True or false?
False – eclipses would stop happening
False – the tilt has no effect on eclipses
True – the three would line up every month
True, but only lunar eclipses would occur
43.
During a solar eclipse, the Moon's penumbra covers a much larger area of Earth than its umbra, so far more people see a partial eclipse than a total one. True or false?
False – the umbra is the larger region
True – the umbra is only a narrow strip
False – both regions are exactly the same size
True, but partial eclipses happen at night
44.
Because the Moon is much smaller than Earth, its umbra can never cover the whole of Earth's day side. True or false?
False – the umbra covers all of the day side
False – the Moon is bigger than Earth
True, but it covers the whole night side at once instead
True – it covers only a small patch at a time
45.
A lunar eclipse can happen on a night when the Moon is a thin crescent. True or false?
False – it can only happen at full moon
True – any phase can be eclipsed at night
True, but only when the crescent is thin
False – it can only happen at new moon
46.
Earth's shadow has both an umbra and a penumbra because the Sun is a large light source, not a point. True or false?
False – Earth's shadow has an umbra only
False – the penumbra is caused by light reflected from the Moon
True – light from parts of the Sun reaches the edge
True, but only because Earth is transparent
47.
During a total solar eclipse the Moon appears as a black disc because the side facing Earth is not lit by the Sun. True or false?
False – the Moon switches off its own light
True – the lit side faces the Sun at new moon
False – the Moon is black because it is hot
True, but only when the Moon is a full moon

False – towns see solar eclipses more often
False – each town sees every eclipse
True – lunar ones are seen from half the Earth
True, but only because lunar ones last minutes
50.
If the Moon were larger but stayed the same distance from Earth, annular eclipses would happen more often. True or false?
