The solar system is an orderly one, which reflects its formation, 4.5 billion years ago. The sun makes up 99.8% of the mass of the solar system. The planets orbit the sun in orderly fashion, and the moons orbit them. Asteroids and comets are small, and most move in orderly fashion, but are occasionally diverted into paths that cause them to collide with the earth or other planet – with disastrous results.
The sun’s mass makes up 99.8% of that of the solar system. The planets move around the sun in almost-circular orbits, all in the same direction, and almost in the same plane. They are kept in their orbits by the sun’s gravity. Moons orbit most of the planets, kept in orbit by the planets’ gravity. Asteroids orbit the sun, mostly between the orbits of Mars and Jupiter; trans-Neptunian objects (TNOs) orbit the sun, mostly beyond Neptune. But asteroids and TNOs can be deflected into more elongated orbits that may cause them to collide with the earth or other planets.
3.1 identify components of the solar system, including the sun, the earth, and other planets, natural satellites, comets, asteroids, and meteoroids, and describe their physical characteristics in qualitative terms (e.g., The earth’s surface is very young; much of it is covered with water. The moon is the earth’s only natural satellite. Comets are the largest objects in our solar system; their centres contain rock particles trapped in frozen liquid; their tails are made up of gas and dust.)3.2 identify the bodies in space that emit light (e.g., stars) and those that reflect light (e.g., moons and planets)
Lesson Goal(s) and/or Focus of Instruction
Description of Student task
Diagnostic or Formative Assessment
Assessment tool
How will you know when each child has reached the goals? Assessment Criteria/Look Fors:
1B Students complete diagnostic questionnaire to determine prior knowledge and misconceptions they bring into the key learning of the Solar System.
Read diagnostic questionnaires submitted by students. Record major misconceptions as well as areas of strength for both individuals as well as the group.

2B One of the two big ideas identified by the ministry for this unit is ‘Earth is a part of a large interrelated system’. To help us build on this fundamental concept of systems, we activate student’s prior knowledge of systems they are familiar with using an in depth focus on the human body as a system, which the students studied in grade 5. We use this example to consider what it means to be a system.Lesson Plan:  AV Astronomy part3  (see pages 119 to 127)

BLM:  AV Astronomy part3 (see pages 128 to 129)

3B Now that we have activated prior knowledge of systems, the next step is to activate the students’ prior knowledge of our solar System. In order to do this we will complete the “K” and “W” portions of a KWL chart.Download:  Sample Solar System KWL



Students will share their knowledge and understanding of the solar system to the class KWL chart. Be sure to include all students in sharing not just those that have lots to share to gain insight of areas of strength and need of the class.
4B Building on the ideas your students shared in the KWL, this lesson highlights the parts of our solar system. First students watch a video that explores key features of our Sun. Next students watch a video takes them on a journey through the rest of our solar system, highlighting the major components that comprise of our solar system. The final video of this lesson discusses why Pluto was demoted from its planet status to a dwarf planet and also gives mention to the Kuiper Belt and Oort Cloud objects that exist beyond Pluto.

Have students write two truths and a lie regarding the information presented in today’s videos. Students submit the three sentences. The teacher keeps them until the next lesson, and then reads them to the class, having the other students try to identify the lie from the other two true statements. By reading the statements the teacher can assess the learning from the previous day.

Below is a link to an overview of Two Truths and a Lie, as well as an example of statements that pertain to this lesson.

5B Using the Smart Notebook file provided teachers can create a model diagram of our solar system, which includes each of the major components, right in front of their students. Teachers could use this file in a computer lab in order to allow the students to also construct the model diagram along with the teacher.Download: Construct our Solar System

Download: Solar System Scale Activity

In lesson 12B students will construct their own model of the solar system using smart notebook software.
6B The activity link below connects to a web quest in which the students explore the main components of our solar system in further detail, learning what each of the main components in made of and other interesting facts. This activity requires each student to add important information to a pre-created PowerPoint. Once the task is completed, students could present to the class or simply save and print for their own notes.

Have students print and submit the final product of their slides to ensure that they have been complete in full and with satisfactory accuracy.
7B Next, students are provided a planetary fact sheet. Students use Venn diagrams to help them compare and contrast the planets.Download: Planetary Facts Venn Diagram Activity
Have students submit their final Venn diagram within their student handout which compares planets that have a longer orbital period than Earth, more moons than Earth, and no magnetic field. Teachers can do a quick skim of the submitted papers to identify those who get it and those who may need extra practice.
8B Using the Venn Diagrams in lesson 7B will help the students to analyze the data in the table allowing them to recognize similarities and differences. In this lesson, students are explicitly taught how to make an effective comparison information paragraph. The Answer Sandwich model is used as a framework, and model responses and a graphic organizer are provide as tools to help the students construct their paragraphs.Download: Planetary Comparison info paragraph

Download: Answer sandwich comparison

checklist and/or rubric
Use criteria on checklist (gist statement, supporting evidence, transition words, and concluding statement) to assess the student’s knowledge and understanding and ability to write an effective comparison information response. Provide the students written feedback to improve their response.

Download: Information paragraph Checklist

8.5 B Through this activity, students will become more familar with both the unique characteristics and the similarities of comets, meteors and asteroids. Students will also learn how to group and sort information with the use of Venn diagrams.

Lesson: The difference between comets, meteors and asteroids

9B Students use the checklists and descriptive feedback to improve their responses, and then they resubmit for conferencing.
Teacher gives further oral feedback in preparation for future comparison writing and the upcoming summative evaluation.
10B After the students have knowledge of the components In our solar system, it is important to understand the relative size of these objects in relation to each other. A PowerPoint file is provided to use as a lesson starter or hook. A question is posed to the students asking if it is possible for a moon to be larger than a planet. It follows with a graphic showing two moons that are larger than Mercury.Activity: Solar system relative size of planets

Video: Our Solar System: Size of Planets and Stars to Scale
Students complete exit cards to reflect on their experiences with these activities.

11B In order to help students appreciate the vast distances between planets try the following activity. Activity: Distance Between Objects in our Solar System.

Activity: Distance Between Objects in our Solar System (Beads).

Activity: Solar System Model by walking it out

Students complete exit cards to reflect on their experiences with these activities.Download: Exit Card Vast Distances Between Planets
12B Students revisit a similar Smart Notebook file to the one in which they constructed a model of the solar system. Students are able to use their notes and their knowledge from the past few lessons to construct a model of the solar system on their own.
checklist/ rubric
Students may either save their files for the teacher to view or the teacher may prefer to have the students print the page in which they created their model solar system. Students are assessed for the Knowledge and Understanding the solar system.Download: Checklist Rubric Solar System diagram

14B Complete “L” portion of KWL chart
Download: Sample Solar System KWL
asteroid A small (up to 1000 km), rocky object that orbits the sun, mostly between Mars and Jupiter — the “asteroid belt”.
comet A small (typically 1-100 km), icy object that orbits the sun, mostly beyond the orbit of Neptune. It is made up of a nucleus (solid, frozen ice, and dust), a gaseous coma (water vapor, CO2, and other gases) and a tail (dust and ionized gases). Its long tail of gas and dust always points away from the sun, because of the force of the solar wind. The tail can be up to 250 million km long, and is most of what we see.
crater A large, usually circular hole made when an asteroid or comet collides with a planet or moon
gravity Gravity is a physical force that pulls objects together. Every bit of mass produces a gravitational force; this force attracts all other masses. The more massive an object, the stronger the gravitational force. Newton formulated the law of gravity.
orbit An orbit is a elliptical (closed) path that an object takes as it revolves around another body.

planet A planet is a large celestial body that orbits a star and does not shine on its own. [There are eight planets orbiting the sun in our solar system.]

trans-Neptunian object Trans Neptunian Objects (TNO’s) are small (typically 1-1000 km), icy objects that orbit the sun, mostly beyond the orbit of Neptune. They are comet nuclei! Yes, Pluto is a large TNO, but not the largest..
meteor The streak of light that a meteoroid makes if it falls through the earth’s atmosphere
meteoroids Small, rocky objects that travel through space
meteorite A meteoroid that survives its trip through the earth’s atmosphere and lands on the ground.
zodiac The zodiac is a band of 12 constellations along the ecliptic. The constellations in the zodiac include: Capricorn (the goat), Aquarius (the water bearer), Pisces (the fish), Aries (the ram), Taurus (the bull), Gemini (the twins), Cancer (the crab), Leo (the lion), Virgo (the virgin), Libra (the balance), Scorpio (the scorpion), and Sagittarius (the archer).
  • The stars are part of the solar system.
  • The positions of the sun, moon, and planets in the sky at your birth affect your future life (astrology).
  • Astronomers have discovered over 300 planets around stars other than the sun, mostly using a technique developed by Canadian astronomers.
  • Canadian astronomers have been part of the teams that have obtained the first images of planets, and planetary systems around other stars.
