Lesson 1
In "Where does space begin" what distance is identified as the edge of space?
20,000km
Why is Celestial observation hard in cities?
light pollution
Why is it important to know the difference between Mass and Weight?
when analysing scenarios involving forces and motion, understanding the difference between mass and weight helps in designing appropriate systems for launching, navigation, stabilisation, and life support.
How has space junk been 'removed' from Earths orbit?
Grappled and thrown out of earths gravity (or something similar)
Name the planets of our solar system
Venus, Mercury, Mars, Jupiter, Saturn, Uranus, Neptune, Earth, Pluto
What is the name of the edge of space?
The Karman Line
How do Telescopes help us identify planets?
A telescope can magnify distant objects and collect more light than our eyes, allowing us to see faint stars, details of planets, and deep-sky objects like galaxies that are otherwise invisible to us.
What is Newtons 1st, 2nd and 3rd Law2?
An object remains at rest, or in motion, at a constant speed in a straight line unless acted upon by a force.
The acceleration of an object depends on the net force acting on the object and the mass of the object.
For every action there is an equal and opposite reaction
Give an example of Natural and Man Made space debris
Naturally occurring debris including: comets, asteroids, meteoroids, interplanetary dust
Man-made or orbital debris including: expended rocket stages; old, non-operational satellites; components released during spacecraft separation; fragments generated from collisions or disintegration events; paint flakes or solidified liquids expelled from spacecrafts.
What happens when you drop a ball on Earth vs Jupiter? (If the atmosphere was the same)
Why is this the case?
The ball falls faster on Pluto.
Gravities affect on mass would cause the ball on Earth to drop slower than Pluto due to the increased gravity causing the balls mass to 'weigh more'
Name 4 things that would not exist if we did not have objects in space
GPS, Weather forecasting, telephone, internet, All other reasonable answers accepted
How have stories of the Stars been used to educate families and broader communities?
...(answer of another question)... people used constellations to inform their people about changes in the seasons and climate which helped them hunt for food.
What is Radiation?
How does it effect Space exploration /or/ how do we protect ourselves from radiation?
Radiation is energy that travels through space or matter in the form of waves or particles.
Any reasonable answer on How will be accepted
IE. Earth has a protective field against radiation, this needs to be put into space craft to protect Astronauts from increased solar radiation.
Lead shielding from radiation used in Xrays, Faraday cage to protect information and electronics in secure environments.
How do we detect, track and avoid space debris?
Detect & Track:
OPIR (Overhead persistent infrared) (track with satellites)
GBR (Ground Based radar tracking)
Avoid : move the object on collision or mitigate the risk of the debris disabling the object through system design and redundancies.
Who were the first people to study the stars?
Indigenous Australians who used the sun, moon and stars to predict changes in the season and weather, and in some cases as navigational tools.
What functions does the ADF use satellites for? (at least 3)
reconnaissance, intelligence, communication, (deterrence, defence, attack)
all reasonable answers correct.
Who is responsible for what? Copernicus, Kepler, Galileo, Newton
Proposed the laws of planetary motion
Placed the Sun as the centre of the solar system.
Laid the groundwork for modern astronomy.
Laws of motion and universal gravitation.
Kepler - Proposed the laws of planetary motion
Copernicus - Placed the Sun as the centre of the solar system.
Galileo - Laid the groundwork for modern astronomy.
Newton - Laws of motion and universal gravitation.
Microgravity.
List 4 places you could experience microgravity
Moon, Freefall, ISS, Mercury, Mars, Pluto
may be additional answers, you can check here if needed https://www.exploratorium.edu/explore/solar-system/weight
Why is a fleck of paint more dangerous in space than on Earth?
SPEED, no forces acting against the paint to slow it down basically makes it into a bullet.
(or any similar/reasonable response)
What was your guest speakers name, rank and role in the ADF
Not naming ADF members online because OPSEC,
SGT , ASOP
In a group:
What connections between life on earth and our understanding of the solar systems did you make in lesson 1?
How did building these connections shape your perspective of the space industry?
All teams who have an answer to both questions get a point
In a Group:
Considering the alignment of ancient structures to celestial bodies, how does this reflect a universal human desire to connect with the universe?
All answers correct, all teams get the points
In a Group:
How did learning and applying new knowledge during this experiential challenge your ability to remain focused on the task? (Key idea - Persistence)
What skills do you think you could improve based on your experience with this task? (Key idea - Self-awareness)
All valid answers accepted
In your groups:
In this lesson you started by presenting your understanding of space and satellites to the class.
What were the factors that allowed you to achieve success in this task as part of a team? How will you develop your skills to keep improving at this?
(written response in your book = answer, no need to share)
Everyone is correct
Asteroids and Comets.
In your group find the shape, size and composition of any known asteroid or comet.
first to buzz in with all 3 listed gets the points.
