We will learn about our place in the system that affects life on earth through looking beyond into space and making models
Factual Question: How can we study ecosystems? What makes up an ecosystem? What makes an ecosystem healthy?
Conceptual Question: What can scientists and others do to understand ecosystems and what makes ecosystems healthy? How do scientific innovations and daily life decisions help to keep ecosystems healthy?
Debatable Question: To what extent will scientific innovations be able to keep ecosystems healthy? To what extent can we and should we rely on scientific advancements to 'fix' environmental damage that human activity has caused?

Reflective - we will reflect on the impact of science on our understanding of our place on earth and in the universe.
Objectives
Objectives
Find out how the earth's system work together to make it a place we can live, how those systems have changed, and how the earth came to be the way it is now.
Explore the ways in which scientists have researched and discovered the earth's system, and the role of space technology in helping us to understand more about the earth.
Take action to evaluate the costs and the benefits of space research, and form an opinion about its value.

In this unit, we have outlined and summarized our local neighborhood in space, the Solar System. We have described a theory for the formation of the Solar System and outlined the main Earth systems. We have evaluated evidence produced from space missions and from research on the Earth and explored how this evidence has been applied to build a scientific model of the way the Earth works and supports life. We have applied our understanding of these systems to see how they are inter-related
Reflection Factual Question:
What is in the Solar System? Where is the Earth? What is the structure of our planet?
Reflection Conceptual Question:
How do different systems of the Earth affect each other? How do models help us to understand Earth’s systems? How does knowledge from space exploration help us to understand the Earth?
Reflection Debatable Question:
To what extent does looking into space help us to improve our models of Earth’s systems?

The International Space Station (ISS) is a space station, or a habitable artificial satellite, in low Earth orbit. Its first component launched into orbit in 1998, the last pressurized module was fitted in 2011, and the station is expected to be used until 2028. The station is the result of collaboration by many countries.
Look at the picture above and watch the video
The first section of the International Space Station (ISS) was launched in 1998, and the station has been occupied by humans since 2000 the longest period of continuous human occupation beyond the Earth! The station is the result of collaboration between the United States, Russia, Japan and the European Union.

WHERE IS THE EARTH?
For millennia, looking up into the night sky has prompted humans to ponder where we are, and to think about our place in whatever universe they understood. On a dark night, a long way from a town or city and when there is no moon, the human eye can see around 4500 stars. This is, of course, the tiniest fraction of the total number of stars in our galaxy alone, which is estimated at between 100 and 400 billion. With powerful telescopes, it is possible to see beyond our own galaxy to millions more. Stars are not the only things we can see when we look up in the night sky. Figure 6.3 shows part of the night sky taken from the northern hemisphere over a few minutes.
You can see the stars in the image as clear, still points of light. But the white streak is caused by something much closer to home it is the light trail left by the International Space Station (lSS) as it moves in orbit over the Earth. Similarly, at different times of the year and from different parts of the Earth we can see our nearest neighbours, the planets, moving through the night as Earth turns on its axis.
The very first images of the Earth from space were taken using high altitude rockets as long ago as 1946. These images were black and white and showed only part of the Earth. When the United States began its Moon programme, humans were for the first time able to turn around and look back at our planet in its entirety, and the famous ’Blue Marble’ photograph (see Figure 6.6 on page 119) had a huge impact. We now take images of the Earth for granted, so it is hard to imagine what it was like to have seen our home in this way for the first time.
The system of objects that orbit the Sun is known as the Solar System. Some of these objects are, in turn, orbiting others for example moons, or human-made objects such as the ISS. These are termed satellites. The number of known artificial (human-made) satellite launches is around 4000, although only about 1000 of these are still operational. The Solar System is our neighbourhood in space, and we have been actively exploring the neighbourhood since the late twentieth century. The first exploratory space probes were sent out into the Solar System in the late 1950s.
