What is the velocity of the passenger relative to Jack? (speed+direction) b. What is the velocity of the passenger relative to the bus? (speed+direction) 5 Frame of Reference & Elliptical Orbits /11 To a rough approximation, everything in the sky seems to move in circles around Earth — the Sun, the Moon, the planets, and even the stars. For thousands of years, astronomers tried to model the motion of the planets using circles or combinations of circles — partly because the circle was such a “perfect” shape. In 1543, Polish astronomer Nicholas Copernicus told us that Earth and the other planets actually orbit the Sun, and that the Moon orbits Earth. But he still described these orbits as circular. Then in 1609, German astronomer Johannes Kepler proved that the actual shape of Mars’ orbit is an ellipse. It followed that all of the planets follow elliptical orbits around the Sun, with the Sun at one focus point.

National Indigenous Peoples Day is on the summer solstice in June There are many stone circles, often called Medicine Wheels, in Alberta and Saskatchewan. Iniskim Umaapi is an archaeological site of the Blackfoot Nation located south of Bassano, Alberta. It has been dated to be over 5000 years old Pahpamiyhaw asiniy, the Manitou Stone, the Stone God. 320 pound meteorite currently at the Royal Alberta Museum. Turned to the correct angle, the stone reveals the profile of a man’s face, believed by some native groups to resemble that of the creator. No travelling tribes in the vicinity would pass the Manitou Stone without paying homage The Woman Who Went To The Moon - read here Makinak: The Turtle by Wilfred Buck Discuss: What are some constellations that you have heard of? What do you know about these constellations? Does anyone have any experiences, stories or memories involving the night sky? Wilfred Buck describes how The Turtle represented a “living calendar.” What did The Turtle tell Nehiyawak (Cree) communities about Earth's position in the solar system? Is there anything else that you found interesting or informative from Wilfred Buck’s Makinak Constellation Story? “‘All my Relations’ Our relations do not just refer to our family, communities and nations but to mother earth, sky father, grandmother moon, and our brothers and sisters in the plant and animal regions. ‘All my relations’ also encompasses the spirit people — those who came before us and those not yet born.” - Kukwtsétsemc and Nia:wen, Dr. Rod McCormick, Kanienkehaka Using the knowledges presented in the video, how does constellation storytelling support the idea of “All my Relations”? (Who are your relations? Who has passed this knowledge onto you? Who will you pass this knowledge onto? What will you use this knowledge for?) Reflecting on traditional stories While listening to the story list any references to the stars, space, seasons, and astronomy and what natural phenomenon they explain. Add a drawing.

Interferometry can be performed by a single telescope taking multiple images or by an array of telescopes all taking images of the same object. Radio Telescopes - A radio telescope uses an antenna and receiver to detect long, low-energy waves at the far end of the electromagnetic spectrum. Through the use of computers, radio waves can be used to form a picture of what is not otherwise visible to the human eye. Radio Waves - Radio waves are long, low-energy waves at the far end of the electromagnetic spectrum. Radio waves move at a frequency below what the human eye can detect. Telescope Array - A telescope array is multiple single telescopes arranged in a network so, together, they function like a very large single telescope. Science catch Up Day!

Locating Objects In Space To pinpoint a location (both in space and on Earth) you need 2 coordinates. Azimuth Altitude Measured CLOCKWISE from Measured VERTICALLY from hee NORTH HORIZON Uses a COMPASS Uses an ASTROLABE Maximum value is 3590 Maximum value is 90 Activity - Build an Astrolabe Build an astrolabe and use a compass to find the following objects in the classroom Azimuth Altitude Clock Wifi Router Top of Fume Hood Other:____________ Did everyone get the same coordinate values? Why or why not? PARALLAX 13 Sky Coordinate Practice Altitude - Altitude is the angle of elevation (up to 90°) above the horizon in a horizon coordinate system. Azimuth - Azimuth is the number of degrees clockwise from 0° north (the point along the horizon below an object in space) in a horizon coordinate system. Cardinal Directions - Cardinal directions are the four main points on a compass (north, south, east and west) that reflect the directions on a globe. Compass - A compass is a magnetic navigation device that shows cardinal directions. Horizon - The horizon is the line at which the Earth and sky appear to meet. Horizon Coordinate System - A horizon coordinate system is a method used to describe the position of objects in space based on the observer measuring azimuth and altitude from the horizon. Zenith - Zenith is the point in the sky directly above an observer (an altitude of 90°). Sky Coordinate Practice Locating Objects Quizziz Try it as many times as you like BEFORE the due date posted in Google Classroom. I will keep your highest score! P. 15-16 - Estimating Distance - Parallax & Triangulation You will need: Insert Lesson Introduction Video Here Remin d ers Estimating Distance - Parallax & Triangulation Parallax is the apparent shift in position of an object based on the position of the observer. Example - Thumbs up! Your thumb should have shifted more with one eye than the other - the eye that was closest to your thumb. With parallax, the closer the object is to the observer, the more it appears to shift. We can use parallax technique to estimate the distance of an object that is very far away. This is also called TRIANGULATION. 15 Parallax Technique / Triangulation 1. Create a Baseline - Must be a long, straight line that spans either side of the object 2. Measure the Angles - Stand at either end of the baseline and measure the angles from this line to the object. 3. Scale Drawing - Determine your scale (example: 1cm = 10 m) and draw the scenario you have set up as precisely as possible. 4. Calculate the estimated distance - Measure the distance from the drawn object to your drawn baseline and use your scale to convert this to the estimated distance. The longer the baseline the more accurate the estimation Triangulation of Stars When using triangulation, your estimation will be more accurate with a longer baseline To get more accurate estimations of the distances to stars, astronomers use two sightings of the same star taken 6 months apart. The baseline in this case will be the diameter of the orbit of Earth around the sun - much bigger!! (2AU) 15 Let’s Try it out! - Triangulation Units of Measurement Space is BIG - you can't use com, m, or even km to measure distances! Astronomical Unit (AU) 1AU = distance from the Earth to the Sun = 150 000 000 km Used to measure distances within our solar system. Light Year The distance light travels in one year. Used to measure distances beyond our solar system. 1 Light Year = 63 240AU Speed of light is 3x108 m/s Milky Way is 1000,000 LY across Closest star - Proxima (Alpha) Centauri - 4.2LY away 16 Astronomical Unit - An astronomical unit (AU) is the average distance between the Earth and Sun and is equivalent to approximately 150 000 000 kilometres. Doppler Effect - The Doppler effect is the apparent change in the frequency of waves depending upon whether an object is moving towards or away from the observer. Parallax - Parallax is the apparent change in position of an object in the distance when viewed from different angles.

Complete new assignment - Locating Objects In Space - FOR MARKS P. 17-18 - Composition of Stars - Spectroscopy You will need: Insert Lesson Introduction Video Here Remin d ers Composition of Stars - Spectroscopy 1. Background Isaac Newton passed a beam of light through a prism to produce a spectrum of colors. If you pass the light through a narrow slit before sending it through a prism (a spectroscope is a device that does this) the spectrum will be in more detail. Joseph von Fraunhofer used a spectroscope to observe the spectrum produced by the Sun. He noticed dark lines, called spectral lines, but didn’t know what they meant. 17 Composition of Stars - Spectroscopy 1. Background Spectroscopy: the study of how light interacts with matter Stars are made of matter with specific ELEMENTS that leave a fingerprint (spectral lines) telling us what they are made of when heated. Nuclear fusion of elements inside the star gives off energy (electromagnetic radiation) that we can use to identify what it is made of. 17 2. Spectroscopy Explained The spectra of the star are then compared to known spectra of elements to determine the star’s composition. This is called spectral analysis. A spectrometer is used to do this. 17 3. Spectral Analysis Mini- Lab (_____/12 = _____%) A. List the chemical elements in: (3) a. Mystery Star 1 ________________________________________________ b.

Canada’s Future in Space Propelling Canada Farther - to the ISS and beyond! Innovative Health Technologies Lunar Gateway ○ What is it? ○ What is Canada’s contribution? Describe it. ○ The Gateway will be: Unlike the ISS, the Gateway will not be crewed continuously, though it will be inhabited at least once a year. As an artificial intelligence-based robotic system, Canadarm3 will be able to tend to the Gateway when no humans are on board, including operating science experiments aboard the lunar outpost Like the ISS, the Gateway will be assembled in stages, using both NASA and commercial launch vehicles. The first two elements of the Gateway – the Power and Propulsion Element (PPE) and the Habitation and Logistics Outpost (HALO) – will launch together in 2025. Other modules will be added afterwards. The Gateway is expected to support science and technology demonstrations by 2026 4. The next generation of astronauts!

Space Is Trying To Kill You a. Microgravity - body does not have to work against Earth’s gravity b. Pressure - much lower in space (or Mars). Affects breathing and all cells. Space is a vacuum c. Oxygen - We need it to live. Also need to get rid of CO2 d. Temperature - wide ranges of temperatures depending on the sun (-150oC to 200oC) e. Radiation!!! - Gamma rays and other radiation (cancer, cataracts, etc?) 29 Life In Space 2. Life Support (we win!) The Environmental Control and Life Support System (ECLSS) is a system of regenerative life support hardware that provides clean air and water to the International Space Station (ISS) crew and laboratory animals through artificial means. The creation of the ECLSS allows for the accommodation of more crew on the Space Station, extends the time crew can stay in space, and significantly reduces the cost of operating the Space Station. The ECLSS consists of two key components, the Water Recovery System (WRS) and the Oxygen Generation System (OGS). 29 29 3. What Happens if Your Body is Exposed to the Vacuum of Space? 4.

Earth Hazard Space Impact on Humans Gravity pulls humans toward Earth’s surface giving them weight. Weightless in orbit Gases that make up Earth’s atmosphere distribute heat from the sun creating a balance in global temperatures. Temperature Atmospheric gases push on our bodies from all directions. Fluids inside our bodies push outwards creating a counter Air pressure balance. Space Junk 31 Distance From Earth We are able to move about and travel freely, interacting with friends and family. Isolation and Confinement Earth’s atmosphere and magnetic field prevent cosmic radiation from Radiation causing damage to life on Earth. High supply on Earth.

I worked well in groups when collaborating on labs and assignments. I do my fair share of the work and help create and evaluate ideas. When collaborating I am positive, focused on the task at hand, and respectful to my peers. I use appropriate language to communicate ideas, procedures and results I was safe in the science lab; on task, following safety guidelines and expectations. I show concern for safety in planning, carrying out and reviewing activities. I keep my work organized and in my binder and/or duotang in order. I don’t lose my work. I am well prepared for my tests and quizzes having made a complete review book and studied ahead of time. I ask questions about concepts covered, labs, homework, and other things that I am unsure or want to learn more about. I actively participate in class discussions, raising my hand to contribute. I take risks even if I could be wrong. I show an interest in science-related questions and issues, and think about my own interests and career possibilities in science. CURRICULUM CHECKLIST E P S L I I can describe the components of the universe and explain how understanding has changed over time I can describe different kinds of telescopes and explain how each helps shape our understanding of space. I can describe and measure location, distance, motion & composition of bodies in space. I can explain scientific principles involved when solving problems and developing technologies for space travel. I can analyze risks versus rewards when developing and applying space technologies.
