Missed lesson

Missed lessons: it is your responsibility to catch up with the work before the next lesson. This is in the school rules. It is also really important if you want to have all the work for tests. You will not get any sympathy or test concessions if you do not catch up as the resources are here !

Grade 9 Short Physics Exoplanet Resources

This is a page of links to resources which might be helpful for the project, depending on how deep you want to go!

If anyone finds good resources or links, please let me know and they can be added here.

Wikipedia page Exoplanets   Good background on what they are, methods of detection from Earth, etc. As always, if you use info from wikipedia, check its credibility.

Nasa site: Exoplanets this is kept up to date and can be considered a credible source.

SETI institute: What is an Exoplanet?  SETI is the'search for extra terrestrial intelligence' so has a goal of finding aliens!   

The Wow Signal  5 minute video explanation of what it is

Video: The Most Terrifying Planets 22 minutes - this is our interpretation of what conditions might be like on some extreme exoplanets. This was the video you were set for homework earlier.

Netflix series: 'Alien Worlds'   Four episodes, each of 45 minutes. This is an exploration of what life might be like on other planets, presented as a nature documentary. It's not difficult, but it is lengthy.

Types of planets - NASA site  and BBC site which discuss the planets in our Solar System.

Remember there are rocky (aka terrestrial) planets. gas giants and dwarf planets

BBC Earth Weather on other planets

ESA - seasons on other planets   BBC - do other planets have seasons?   National Geographic - Uranus (which as weird rotation and seasons)

Video - Simulation of gravity on other planets (in our Solar System)  8 minutes

What if we grew up on other planets? V sauce video which was shown in grade 8 about 20 minutes

Planet maker simulator - this is very pretty but does not really tell you about the conditions on the planet you create.

Video: How to find a planet you cannot see.

Types of stars - includes the colours, temperatures and ages. You should be looking at MAIN SEQUENCE stars maybe G or K type. Others are possible (but NOT neutron stars or black holes)

Article on 20 years of Uranus observations

Uranus - Life with weird seasons    or  Bizarre characteristics videos

Orbital period calculator  

Habitable zone calculator: 

Planet temperature calculator: 

Exoplanet discovery calculator  - this sounds good but actually gives details about how existing exoplanets were discovered using things like redshifts (radial velocity), transit times (detecting brightness changes) and astrometry (how much the star's orbit 'wobbles' as seen from earth). This level of investigation is NOT needed for the project but because you might stumble across it, then I thought I'd give you some info.

Tidal locking: why do we only see one side of the Moon? Does the moon rotate on its axis - yes.  This video explains it simply and visually.   Another video which explains the origin of tidal locking (it's really common). What might life on a tidally locked planet look like?   And finally another video 'What if the Earth was tidally locked to the Sun?'
