🔍 Key Elements in the Image

#### 1. Key Question (Main Focus):
> *"What characteristics do all living things share?"*

This is the central question for the lesson. The answer is provided in the Lesson Summary section.

✔ Answer to the Key Question:

All living things share the following characteristics:

| Characteristic | Explanation |
|----------------|-------------|
| Made up of cells | Cells are the smallest units of living things. All organisms are composed of one or more cells. |
| Reproduction | Living things produce new organisms through sexual or asexual reproduction. |
| Based on a universal genetic code | DNA carries genetic information, and the genetic code is nearly identical across all life forms. |
| Growth and development | Living things grow and develop; multicellular organisms go through differentiation. |
| Need for materials and energy | Organisms require nutrients and energy to survive (e.g., food, sunlight). |
| Response to the environment | Organisms react to internal and external stimuli (e.g., light, temperature). |
| Maintaining internal balance (Homeostasis) | Living things regulate their internal conditions (e.g., body temperature, pH). |
| Evolution | Over time, populations change and adapt to their environments through natural selection. |

🧠 Reading Tool: Main Idea and Details Chart

This chart helps students organize information by identifying the main idea (characteristic) and details (supporting facts).

Example:
- Main Idea: Made up of cells
Detail: Cells are the smallest units of living things.

You’re asked to complete this chart — but it's already filled out in the image. So, if your task was to fill it in, you’ve got the correct answers.

📚 Vocabulary Section: "BUILD Vocabulary"

- Bias: A personal preference or point of view that may affect objectivity.
- Word Origins: "Bias" comes from the French word *biais*, meaning “slant” or “slope.”
- Sample Answer: A scientist working for a company might favor data supporting their company’s products (e.g., ethanol over solar power), which shows bias.

👉 This section teaches students to recognize and avoid bias in science.

🔬 Science and Engineering Practices

These are core skills used in both science and engineering:

1. Developing and Using Models
→ Scientists use diagrams, 3D models, and math models to represent systems.

2. Using Mathematics and Computational Thinking
→ Ratios, percentages, and unit conversions help analyze data.

3. Constructing Explanations and Designing Solutions
→ Scientists form evidence-based explanations; engineers design solutions.

4. Engaging in Argument From Evidence
→ Scientists and engineers defend ideas with logical arguments supported by data.

✔ Lesson Summary

Reiterates the key idea:
> *"Living things are made up of basic units called cells, reproduce, are based on a universal genetic code, grow and develop, obtain and use materials and energy, respond to their environment, maintain a stable internal environment, and change over time."*

This is a concise list of the eight characteristics of life.

✔ Task Completion & Final Answer

If your task was to answer the Key Question: "What characteristics do all living things share?", here is the final answer:

> All living things share these characteristics:
> 1. They are made up of cells.
> 2. They reproduce.
> 3. They are based on a universal genetic code (DNA).
> 4. They grow and develop.
> 5. They need materials and energy.
> 6. They respond to the environment.
> 7. They maintain internal balance (homeostasis).
> 8. They evolve over time.

These eight traits define life and are consistent across all organisms—from bacteria to humans.

💡 Additional Notes

- The book emphasizes scientific integrity (avoiding bias).
- It connects science to real-world applications (e.g., ethics in science, energy choices).
- Students are encouraged to circle answers to key questions and underline unfamiliar words.
