Part B: Label the diagram by writing the correct scientist’s name in the word box.

#### Diagram Analysis:
The diagram shows images of eight scientists. Based on their appearance and historical context, we can match them with the names from the word bank. Here is the matching:

1. Top Left Image: This scientist has a beard and is wearing formal attire typical of the 17th century.
- Match: Isaac Newton

2. Top Middle Image: This scientist has a beard and is wearing a suit, indicative of the 19th century.
- Match: Alexander Graham Bell

3. Top Right Image: This scientist has short hair and is wearing modern clothing, suggesting a more recent figure.
- Match: Nikola Tesla

4. Middle Left Image: This scientist has a beard and is wearing formal attire, similar to the 19th century.
- Match: Charles Darwin

5. Middle Middle Image: This scientist has a beard and is wearing a suit, consistent with the 19th century.
- Match: Robert Boyle

6. Middle Right Image: This scientist has a beard and is wearing formal attire, indicative of the 17th century.
- Match: Galileo Galilei

7. Bottom Left Image: This scientist has a beard and is wearing formal attire, typical of the 19th century.
- Match: James Joule

8. Bottom Right Image: This scientist has a beard and is wearing formal attire, indicative of the late 19th or early 20th century.
