This quiz will test your understanding of the topic in the lesson, and prior knowledge from earlier in this topic.

Choose the element from the list below that can be synthesised in a main sequence star.

"helium to make elements up to iron" - Match this fusion reaction to the stage of a massive star's life cycle,

"all nuclei to make elements bigger than iron" - Match this fusion reaction to the stage of a massive star's life cycle,

A nucleus of hydrogen-3 contains...

Which phase of a star's life consists of a city-sized body made exclusively of only one type of subatomic particle?

Select the bodies that match the description: makes element nuclei larger than helium via fusion (tick 2 boxes)

Select the bodies that match the description: is formed from a star much more massive than the Sun (tick 2 boxes)

Select the body that matches the description: distributes elements across space after exploding

Select the body that matches the description: makes only helium via fusion

Select the bodies that matches the description: is stable for millions of years (tick 3 boxes)

A source of waves shows a red-shift. This means that....

DIstant galaxies are redshifted. This means that...

The spectrum on the left shows the light emitted by a source on Earth. The spectrum on the right shows the same type of light emitted by a distant galaxy. From this evidence we can conclude... (choose 3)

Hubble discovered that...

Light from nearby galaxy was split into a visible spectrum, and the characteristic lines associated with sodium, normally in the yellow part of the spectrum, appeared in the orange part of the spectrum. From this, we can conclude...

Origins of the universe

Qualitatively explain the red-shift of light from galaxies that are receding

Explain that the change of each galaxy's speed with distance is evidence of an expanding universe

Explain how red-shift provides evidence for the Big Bang model

In this lesson we will explore the scientific evidence available for the origins of the Universe, with a particular focus on understanding the Doppler effect and its importance to our understanding of the formation of the Universe.
