The sun!
All life on earth is made possible by the sun!🌞 Without the sun there would be no heat or light and life on earth would cease to exist. The sun influences our planet in many ways: It drives the weather & the seasons, ocean currents & the climate.
🌎 Earth goes around the sun.
Even though it seems like the sun moves and the Earth is still, the earth is actually travelling around the sun as it spins on its axis.
Check out the mystery science lesson about this: https://mysteryscience.com/astronomy/mystery-1/day-night-earth-s-rotation/378
It takes the earth a year to travel around the sun. Actually ≈ 365.24 days.
The ☀️ Sun and ⭐️ stars appear to travel across the sky from east to west because of the rotation of Earth.
{ shadows }
The sun makes shadows and they change throughout the day. You can tell the time by the suns position and the direction of the shadows.
Sundials- use the suns position to aid in telling time. 🕚

The Planets 🪐
There are 8 planets in our solar system. Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune.
Pluto is considered a dwarf planet along with Eris, Ceres, Makemake and Haumea.

The Dwarf planets are smaller than earth's moon
"We are the planets" this is a fun StoryBots song about the planets.
One of our students made this model to demonstrate the different amounts of time it takes for each of the planets to rotate around the Sun.
Thanks Lucas.
🔆 Don't stare at the sun!
The Sun should never be viewed directly or using simple telescopes or filters. 😵
🌌 Constellations -
The recognizable patterns of stars are called constellations. https://mrgrantclass.weebly.com/sky-science.html
There are 88 constellations recognized by the IAU . •Constellation names and meanings.
☆The North Star- 🌟Polaris, shows the approximate direction of the North Pole. The Orion constellation can be used to find the South Pole. educational-resources/hands-on-activities/how-can-i-tell-which-way-north-night
Historically, people noticed groups of stars and created patterns out of them for purposes like navigation and tracking the passage of time.
Star Clock- Try this Activity -create a clock you can use to tell the time using the big dippers location.
The location of the Big dipper through the seasons. (In the evening.)
Space is 3-D •. Even though stars in a constellation appear to be on the same plane their distances vary greatly. Stars also differ a lot in size & brightness.
If you'd like to know how astronomers measure how far stars are away click here. https://www.windows2universe.org/kids_space/star_dist.html
Astronomical measurements- Astronomers use parallax to measure distances to nearby stars. Parallax is the apparent displacement of an object against the background.
Constellations have names from a variety of sources. The names of ancient constellations mostly come from Greek and Roman mythology, while recent constellations are named after scientific instruments and animals.

☔️ Seasons of the year- The tilt of Earth causes the seasons. When the North Pole tilts toward the Sun it is summer and when it tilts away from the Sun it's winter.
🌔 The Moon's Phases.
Have you ever noticed that the Moon appears to change shape each night. The different shapes are called the Moon’s phases. These are the 8 moon phases.
🌑 New
🌒 Waxing Crescent
🌓 First Quarter
🌔 Waxing Gibbous
🌕 Full
🌖 Waning Gibbous
🌗 Third Quarter
🌘 Waning Crescent
The Moon takes about 29.5 days to complete one cycle
the Dark-side of the moon- We only ever see one side of the moon because it is tidally locked with the earth. This means that the moon has the same rotational period as its orbital period around the earth.
<- watch video.
🗓Calendars- The Moon has been used to measure time throughout history. The international standard (Gregorian calendar) is based on the amount of time it takes Earth to revolve around the Sun.
Lunar calendars follow patterns of the Moon for timekeeping.
Many cultures have unique observations of astronomical phenomena that are connected to time, place, and daily life.
◉ Eclipses
lunar eclipse - A lunar eclipse occurs when the Moon moves into the Earth's shadow. Which happens only when the Sun, Earth, and Moon are exactly or very closely aligned.
solar eclipse - A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby obscuring Earth's view of the Sun, totally or partially.

Grade 8 topic-
Unit C: Light and Optical Systems (Nature of Science Emphasis) Overview: Our understanding of the world is based largely on what we see—both directly, and aided by optical devices that improve and extend our vision. Such tools as the microscope and telescope have helped extend knowledge in a variety of science fields, from the study of cells and stars to studies of the nature of light itself. In learning about light, students investigate its interactions with different materials and interpret its behaviour using a geometric ray model. Students then use their understanding of light to interpret a variety of light-based technologies and envisage new technologies we may use in the future.
