• Students will define system as parts working together, often systems as parts within systems. • Students will experience the solar system to scale by touching objects and walking distances • Students will make observations of biosphere and hydrosphere (life and water) on earth at Blaine Wetland Sanctuary using their senses and tools • Students will compare and contrast evidence of life on earth with evidence (or lack) of life on other planets and their moons

Mercury's thin atmosphere, or Biosphere exosphere, is composed mostly of oxygen (O2), sodium (Na), hydrogen No life found…yet. (H2), helium (He), and potassium (K). Temperatures can reach Source: Nasa.gov April 2019 800° F in the daytime and drop to ‐290° F at night.

Earth is the only planet we know fo to have liquid water at it’s surface. Hydrosphere Geosphere On the surface, earth’s land to water ration is 29% land to 71% water. Earth is the biggest of the four planets closest to the Sun, all of which are made of rock and metal.

MARS Image Source: https://solarsystem.nasa.gov/planets/mars/overview/ What we know about the ASTEROID BELT Atmosphere Hydrosphere Geosphere Biosphere Source: Nasa.gov March 22, 2019 Asteroids are small, rocky objects that orbit the Sun. They are much smaller than planets. They have no air, no living things, and no water that we have found yet at least! Comets orbit the Sun, like asteroids, but have crazy orbits and comets are made of ice and dust—not rock.
Scientists can learn about asteroids by studying meteorites: tiny bits of asteroids that have flown through our atmosphere and landed on Earth’s surface.
