  1. Week 6 A Day

  2. If gravity is eliminated, what would happen to our solar system? Microgravity Can you float in Earth’s atmosphere? What is weightlessnes? I can identify and describe examples of microgravity. STEM VALUE: Design & Systems thinking

  3. Vocabulary: • Microgravity

  4. Warm-up As we watch, answer in the chat: How does gravity impact our day to day life?

  5. What is Microgravity? Microgravity or "weightlessness", is the feeling of almost no gravity. “Micro-” = "very small" microgravity refers to the condition where gravity seems to be very small. https://youtu.be/GSLwvtF4Zo0

  6. Why do Science in Space?! The pull of gravity governs our lives. Our bodies are uniquely tuned to Earth’s gravity, which affects our entire body, from how hard our heart pumps, to the density of our bones. The force of gravity also affects our science. All experiments performed on Earth are subject to gravity, but take gravity away and many things change, opening up opportunities to view systems in a whole new way not possible on Earth. The International Space Station orbits more than 250 miles above the surface of our planet, creating a microgravity environment for research that allows scientists to uncover these changes.

  8. How do astronauts prepare for a life in microgravity? In order to prepare for space flight, scientists have discovered a few ways to create longer periods of weightlessness.

  9. Training for Mars: ZERO-G Flight Longer periods of microgravity (weightlessness) are possible in specialized planes that fly a parabola.

  10. Training for Mars: NEEMO NEEMO - the NASA Extreme Environment Mission Operations project - is a NASA mission that sends groups of astronauts, engineers and scientists to live in Aquarius, the world's only undersea research station, for up to three weeks at a time. Much like space, the undersea world is a hostile, alien place for humans to live. NEEMO crew members, known as aquanauts, experience some of the same challenges there that they would on a distant asteroid, planet or moon. During NEEMO missions, the aquanauts are able to simulate living on a spacecraft and test spacewalk techniques for future space missions. NEEMO

  11. Discussion Questions • Why do they float on the ISS? • Can microgravity be found on Earth? • Why Does NASA Study microgravity?

  12. Virtual Tour: NASA Zero Gravity Facility You have 5 minutes to explore independently! https://www.nasa.gov/specials/zero-g/

  23. Formation of the Solar System: Our solar system formed about 4.5 billion years agofrom a dense cloud of gas and dust. The cloud collapsed, possibly due to the shockwave of a nearby exploding star, called a supernova. When this dust cloud collapsed, it formed a solar nebula—a spinning, swirling disk of material. At the center, gravity pulled more and more material in. Eventually the pressure in the core was so great that hydrogen atoms began to combine and form helium, releasing a tremendous amount of energy. With that, our Sun was born, and it eventually accumulated (gathered together) more than 99 percent of the available matter. Matter farther out in the disk was also clumping together. These clumps smashed into one another, forming larger and larger objects. Some of them grew big enough for their gravity to shape them into spheres, becoming planets, dwarf planets and large moons. In other cases, planets did not form: the asteroid belt is made of bits and pieces of the early solar system that could never quite come together into a planet. Other smaller leftover pieces became asteroids, comets, meteoroids, and small, irregular moons. https://solarsystem.nasa.gov/solar-system/our-solar-system/in-depth/

  24. How Big? Arrange the images in order according to SIZE from smallest to largest.

  25. How Far? Arrange the images in order according to DISTANCE nearest to Earth to farthest.

  26. How Old?? Arrange the images in order according to AGE from youngest to oldest.

  27.
