Question

step 3 – vocabulary (read and do): read each description. then:

1. circle the most important word in the passage.
2. write a short definition in your own words.

nuclear fusion- inside the sun, hydrogen atoms crash together and fuse into helium. this process creates a huge amount of energy that powers the sun. write about what is being created.

solar radiation- the sun’s energy doesn’t stay inside—it moves out through space as light and heat. this radiation reaches earth and other planets. write what two forms this energy takes.

orbiting planets- earth and other planets move in paths around the sun because of gravity. the amount of energy each planet gets depends on its distance from the sun. write what force keeps planets in place.

influence- the sun’s energy affects temperatures, weather, and life on earth. without solar energy, earth could not support living things. write a way the sun’s energy affects earth.

step 4 – evidence model: draw a simple diagram off to the side, label 1, 2 and 3.

1. sun’s core → nuclear fusion makes energy
2. energy travels outward → sunlight reaches earth
3. effects on earth: warmth, plants, weather

Explanation:

To solve this, we'll address each part of Step 3 and Step 4 as per the instructions:

Step 3 - Vocabulary (Read and Do)

1. Circle the most important word in each passage:

• Nuclear Fusion: The most important word is "Nuclear Fusion" (or "fusion" as the core process).
• Solar Radiation: The most important word is "Solar Radiation" (or "radiation" as the energy transfer process).
• Orbiting Planets: The most important word is "Orbiting Planets" (or "gravity" as the force keeping them in place).
• Influence: The most important word is "Influence" (or "energy" as the Sun’s energy is the key factor).

2. Write short definitions/responses:

• Nuclear Fusion:

Definition: Inside the Sun, hydrogen atoms collide and combine (fuse) into helium, producing a large amount of energy that powers the Sun.
What is being created? Energy (from the fusion of hydrogen into helium).

• Solar Radiation:

What two forms? The Sun’s energy moves through space as light and heat.

• Orbiting Planets:

What force keeps planets in place? Gravity (pulls planets into paths around the Sun).

• Influence:

A way the Sun’s energy affects Earth: The Sun’s energy provides warmth, which allows plants to grow (or regulates weather, supports life, etc.).

Step 4 - Evidence Model (Diagram Explanation)

The diagram outlines the Sun’s energy flow:

1. Sun’s core → nuclear fusion makes energy: In the Sun’s core, nuclear fusion (hydrogen → helium) generates energy.
2. Energy travels outward → sunlight reaches Earth: The energy from fusion moves outward from the Sun and reaches Earth as sunlight (solar radiation).
3. Effects on Earth: warmth, plants, weather: The solar energy warms Earth, supports plant growth, and drives weather patterns.

If you need to complete the "blank" part (not fully visible), use the diagram to write a sentence. For example: "The Sun’s energy, created by nuclear fusion in its core, travels outward as sunlight to Earth, where it provides warmth, supports plant life, and influences weather."
