Today we explored the Big Bang Theory - we took the following notes, talked about other theories that are out there, what the difference between a law, theory, and hypothesis is, and did some serious wondering together. Notes... -The universe began as a tiny/pin-sized point of all matter energy and space, then the point rapidly expanded and then cooled and became what the universe is today in about 13.7 billion years Three supporting pieces of evidence for the Big Bang Theory: 1. Cosmic Microwave Background Radiation (CMB) - left over heat extending in all directions from the Big Bang that came from a single point, can be explained through the Doppler Effect 2. Hubble Expansion - the further things are from one another the further they move apart, space itself is expanding and galaxies are moving away from each other 3. Elemental Composition of Our Universe (Nucleosynthesis) - hydrogen and helium can only form in a Big Bang process and it is from these elements that all the other larger elements were made Today we went over the Stellarium Lab as a class and I encouraged students to see if they can find the Moon, Mars, and Polaris tonight! After we completed the following word search.
Please complete the word search for homework if you did not get it done in class! The class started off with an attendance question and then we completed the following two labs!
The class started off talking about the long weekend and then moved onto a short review of constellations and the rotations of the moon + earth with the following videos. After, we learned about the Asteroid belt and Kuiper Belt with the following quick notes and video - then we did a review crossword. Notes... Asteroid Belt - this is the main asteroid belt that is closest to earth, found between Mars and Jupiter. Although there are millions of asteroids in it, the ice and rock that they are made of are all solids that are smaller than other planets in our solar system, the ice and rocks are also more spaced out than you would imagine Kuiper Belt - this belt is the farthest 'thing' from earth in our solar system. There are millions of asteroids in it made out of ice and rock and dwarf plants, such as Pluto, can be found here. The ice and rocks are also more spaced out than you would imagine Asteroid - body of rock (smaller then any planet) that is in our solar system that is also orbiting the sun Meteoroid - rock fragments in space Meteor - lit up rock fragment flying through the atmosphere Meteorite - rock fragment that is manages to hit/come towards earth, or another planet Comet - dust/ice that lights up colorfully and flies across the atmosphere Please bring your completed crossword to class on Thursday! The class did an attendance question and then took the following notes and watched the following videos. After break, we went on a walk to the river and answered the following questions... -What have you learned in the astronomy unit so far? -What are you still wondering about? -How would you like to show your summative knowledge of this unit and why? -What do you already know about the units coming up? (atmosphere, water cycle, plate tectonics, rock cycle and natural resources) Notes... -Universe drawing with 5 different types of galaxies = irregular, spiral (the milky way is an active spiral galaxy), barred spiral, elliptical, & peculiar -There are billion of galaxies with billions of stars in each and many/most have planets orbiting around them -Galaxy = a group of billions of stars that are bound together by gravity *so what makes our galaxy special? 8 planets, a sun and a moon around earth -Constellation = a group of a few points of light in the sky (stars) that appear to form a picture *to find the North Star (Polaris) find the cup of the Big Dipper and look straight up from it. This has been used in the past for navigation. Today the class did an attendance question, did the following demo with these notes, and finished the 'If We Had No Moon' documentary. Notes... -The earth revolves counterclockwise around the sun, ~365 days -The earth rotates on its axis, ~24 hours -The moon rotates counterclockwise around the earth, ~30 days Please hand in your completed documentary questions! The class watched the following video and we clarified the notes from last class. After, we continued watching the 'If We Had No Moon' documentary. The class learned about the phases of the moon and then watch the documentary 'If We Had No Moon' with guided questions.
The class started with an attendance question and then we did the following graph analysis together. After break we worked on the 'In the Stars' activity.
Please hand your graph worksheet, 'In the Stars' drawing, and the written part on Teams! The class took notes on all the planets, watched this annoying song, and then continued working not the solar system! My Very Educated Mother Just Served Us Noodles Mercury - no atmosphere, extreme temps, smallest planet, closes to the sun Venus - closest to earth, similar composition to earth, volcanoes and lava Earth - water found infall three states, O2 + temp makes it habitable, LIFE! Mars - iron rich = red, crazy winds, tall mountains, ice caps, thin CO2 atmosphere Jupiter - largest planet, shores day of any planet, has rain storms Saturn - noticeable ice rings, second biggest planet, hexagon poles Uranus - rings made of ice and dust, orbits on a tilted axis, blue from methane gas Neptune - outer most planet, dark blue colour because of methane, faint ring system (still learning) Today students completed their 'Space Inquiry' project, along with a self assessment, and then we created our own solar system! We also looked at the James Webber telescope photos and then the NASA Juno photos.
Please hand in your 'Space Inquiry Project'! Today we started class with an attendance question and then completed the following 'Planets' worksheet. After, we looked at photos of+from the James Webber telescope and then started the 'Space Inquiry' project on Teams after looking at an example project.
Please complete the following worksheet if you were not here today! |
