Space Explorers: A 4-Week Journey Through Our Solar System

Target Audience: 7-Year-Olds (Grade 1 Level) | Context: Homeschool/Classroom | Integrated Subjects: Science, Art, HASS (Humanities and Social Sciences)

Lesson 1: The Sun – Our Super Star

Learning Objectives: Students will identify the Sun as the center of our solar system and understand that eight planets travel around it.

Materials: A large yellow ball or balloon, 8 different sized fruits or balls (to represent planets), yellow paint, bubble wrap, paper, a timer.

1. Introduction (The Hook)

Talking Point: "Imagine a giant ball of fire so big that a million Earths could fit inside it! That’s our Sun. It’s like the captain of a giant space team, and everyone else follows its lead. Today, we’re joining the team!"

2. Body (I Do, We Do, You Do)

• I Do (Modeling): Place the "Sun" in the middle of the room. Explain that the Sun stays still while everything else moves in a circle called an orbit.
• We Do (Interactive): The "Human Solar System." Have the twins hold "planet" objects. Walk in circles around the Sun. Practice walking at different speeds (inner planets move fast, outer planets move slow).
  ASD Support: Use floor tape to mark the circles (orbits) so the path is clear and predictable.
• You Do (Creative): "Sun Texture Art." Paint a large circle yellow. Press bubble wrap into orange paint and stamp it onto the yellow circle to create the "boiling" look of the Sun’s surface.

3. Conclusion & Assessment

Recap: Ask, "Is the Sun a planet or a star?" (A star). "Does the Sun move around the Earth, or does Earth move around the Sun?"

Success Criteria: The student can point to the center of a model and name it "The Sun."

Lesson 2: The Inner Planets – The Rock Stars

Learning Objectives: Students will name the four rocky planets (Mercury, Venus, Earth, Mars) and identify Earth as our home (HASS connection).

Materials: Gray, orange, blue, and red playdough or clay; small rocks; a map or globe.

1. Introduction (The Hook)

Talking Point: "If you stepped on these four planets, you’d feel solid ground under your boots! They are the 'Rock Stars' of space. One of them is very special because it’s the only one with chocolate, puppies, and YOU!"

2. Body (I Do, We Do, You Do)

• I Do (Instruction): Show pictures of Mercury (small/gray), Venus (hot/yellow), Earth (blue/green), and Mars (red/dusty). Explain that these are the closest neighbors to the Sun.
• We Do (HASS Connection): Look at a globe. Discuss "Location." Earth is our "Home Address" in the universe. Talk about what makes Earth different from the other rocks (Water, Air, Life).
• You Do (Hands-on): "Clay Planet Building." Roll four balls of clay.
  • Mercury: Tiny and gray.
  • Venus: Bright orange.
  • Earth: Blue with green spots.
  • Mars: Red with small pebbles pressed in for "craters."

3. Conclusion & Assessment

Recap: "Which planet is the Red Planet?" "Which planet is our home?"

Success Criteria: Student can sort the four planets by color and identify Earth as the third planet from the Sun.

Lesson 3: The Gas Giants – The Big Balloon Planets

Learning Objectives: Students will describe the outer planets as large, made of gas, and often having rings.

Materials: Shaving cream, food coloring, a tray, circular paper cut-outs, cardboard for "rings."

1. Introduction (The Hook)

Talking Point: "What if you tried to land a spaceship but there was no ground? You’d just fall through clouds for miles! These four planets are giant balls of gas and ice. They are the 'Big Brothers' of the solar system."

2. Body (I Do, We Do, You Do)

• I Do (Modeling): Introduce Jupiter (the biggest), Saturn (the one with the famous rings), Uranus, and Neptune (the cold, blue ones). Explain that 'Gas' means they are like clouds you can't stand on.
• We Do (Sensory Exploration): Fill a tray with shaving cream. Drop in swirls of blue and red food coloring. Let the students use their fingers to swirl the colors, representing the giant storms on Jupiter.
• You Do (Art): "Marbled Planets." Press paper circles into the shaving cream swirls. Lift them up to reveal beautiful, gassy patterns. For Saturn, glue a cardboard ring around the circle.

3. Conclusion & Assessment

Recap: "Can we walk on Jupiter?" (No). "Which planet has the brightest rings?" (Saturn).

Success Criteria: Student identifies that the outer planets are much larger than the inner rocky planets.

Lesson 4: Astronauts and Our Moon

Learning Objectives: Students will understand the Moon's relationship to Earth and imagine the role of an astronaut (HASS/Science).

Materials: Flour or sand in a tray, marbles or rocks, black paper, white chalk, silver foil.

1. Introduction (The Hook)

Talking Point: "Look up at the night sky. Who is Earth’s best friend that follows us everywhere? The Moon! People have actually walked there. Do you think you have what it takes to be an astronaut?"

2. Body (I Do, We Do, You Do)

• I Do (Instruction): Explain that the Moon reflects the Sun's light. It has "craters" (holes) because space rocks hit it. Show a picture of an astronaut's footprint on the Moon.
• We Do (Science Experiment): "Moon Crater Lab." Smooth out flour in a tray. Drop marbles (space rocks) into the flour from different heights. Observe the "craters" they leave behind.
• You Do (Creative Roleplay): "My Space Passport." Fold a piece of paper. On the front, the student draws themselves in a space suit (using silver foil for the helmet). Inside, they "choose" which planet they would visit first and what they would pack.

3. Conclusion & Assessment

Recap: Lay out all the art from the 4 weeks (The Sun, Rocky Planets, Gas Giants, and Moon). Ask the students to put them in the correct order from the Sun.

Success Criteria: Student completes their "Space Passport" and can name at least one thing an astronaut needs to survive in space.

Adaptations for Diverse Learners

• For the ASD Student: Use a "First/Then" board (e.g., "First: Shaving Cream Art, Then: Snack"). If the texture of shaving cream or clay is overstimulating, provide gloves or use a paintbrush instead of fingers.
• For the Neurotypical Twin: Encourage "Extension" tasks, such as labeling the planets with their names or researching one "fun fact" (e.g., "Jupiter has a Great Red Spot") to share with the family.
• Universal Design: All lessons move from high-energy (Human Solar System) to calm/focused (Art/Passport), helping with self-regulation.
