Astronomers study celestial objects (stars, planets, moon, asteroids, comets, galaxies, etc) that exist outside our planet's atmosphere. Astronomy Unit Study + Printables Our first unit study is in celebration of World Space Week! Gaseous planets are giant balls of gas with no solid surface that are larger than terrestrial planets.In the asteroid belt located between Mars and Jupiter.Why do comets' tails always point away from the Sun?Solar winds break apart the comet as it moves towards the sun creating a tail of gas and dust behind it.What is the difference between meteoroids, meteors, and meteorites?a force that pulls (attracts) an object toward another objectthe path an object takes as it revolves around another objectthe rise and fall of Earth's oceans due to the gravitational pull of the Moon and SunWhat two factors affect the gravitational pull between two objects?The mass of the objects and the distance between themWhich celestial body has the greatest pull on the waters on Earth, causing the tides?4 divisions of the year when there are changes in temperature, amount of daylight, and angle of the sun's rays as the Earth changes position revolving around the sunWhat are the three ways that our seasons are different?What season are we experiencing when the Northern hemisphere is tilted towards the Sun?Which season has the longest amount of daylight hours?24 hours, one full rotation of the Earth around its axisWhen the Earth, Sun, and Moon are lined up so that the Moon is in between the Sun and Earth blocking the Sun. It is located in the Milky Way (spiral galaxy) and is in a spiral arm two-thirds of the way from the center of the galaxy.large formations in the universe made up of gas, dust, and billions of stars. 2 0 obj

These can only occur during a New Moon or a Full MoonWhen the Moon and Sun form a 90° angle with the Earth resulting in lower high tides and higher low tides.

This causes a dark shadow to move across part of the Earth.When the Earth, Sun, and Moon are lined up so that the Earth is in between the Sun and the Moon. It creates energy through the process of fusion. STUDY. A unit study works by capturing a child’s attention and helping them understand the pieces of the whole as they fit together. STUDY. 1 0 obj
It is made up of hydrogen and helium. These can only occur during the first quarter and the third quarter (last) moon phases.Because the moon rotates and revolves at the same rateDuring a new moon, where is the moon in relation to the Earth and Sun?It is located closest to the Sun, in between the Earth and the SunDuring a full moon, where is the moon in relation to the Earth and Sun?It is located on the opposite side of the Earth from the SunThe amount of light is increasing and is located on the right side of the moonThe amount of light is decreasing and located on the left side of the moonWhy do we not have eclipses during every New Moon and Full Moon?Due to the tilt of the Moon's orbit around the Earth. Astronomy Unit Information Milestones Domain/Weight: Astronomy 20% Purpose/Goal(s): Students are expected to have knowledge of the progression of scientific explanations (geocentric and heliocentric models) for the formation of the solar system. What is they key component found in stars? %PDF-1.5
It is equal to the distance light travels through space in one year.We use them because objects in the universe are so far apart that we needed a very large unit of measurement.the theory that the universe started from a single point and all matter and energy has expanded out from itgas and dust remnants from the beginning of the universeWhat evidence do scientist use to help estimate the age of the universe?They measure the rate of expansion of the universe and look at the oldest stars.The amount of hydrogen changes causing their color and brightness to change as well.How can astronomers tell that the galaxy is expanding?They look at the energy bands from objects in space and observe the red shift.As the universe expands and galaxies move apart their wavelength of light stretches and the energy shifts toward the red part of the spectrum.the movement of an object moving around (orbiting) another objectSolid rocky planets primarily composed of silicate rocks or metals.
