The task is to identify the names of the scientific tools shown in the images and explain how scientists use each tool. Below is the solution with explanations:

---

12. Laptop

- Name: Laptop
- Usage: Scientists use laptops for data analysis, research, communication, and documentation. They can run specialized software for analyzing experimental results, writing reports, and sharing findings with colleagues.

---

13. Safety Goggles

- Name: Safety Goggles
- Usage: Scientists wear safety goggles to protect their eyes from chemical splashes, dust, debris, or other hazards during experiments. This ensures their safety in laboratory settings.

---

14. Microscope

- Name: Microscope
- Usage: Scientists use microscopes to observe samples at a microscopic level. This tool helps them study cells, bacteria, and other tiny structures that are not visible to the naked eye.

---

15. Graduated Cylinder

- Name: Graduated Cylinder
- Usage: Scientists use graduated cylinders to measure the volume of liquids accurately. The markings on the cylinder allow for precise measurements, which are crucial in experiments involving solutions or reactions.

---

16. Beaker

- Name: Beaker
- Usage: Scientists use beakers to hold, mix, and heat liquids. They are commonly used in chemistry labs for conducting experiments, such as mixing chemicals or observing reactions.

---

17. Pipette

- Name: Pipette
- Usage: Scientists use pipettes to transfer small, precise volumes of liquid from one container to another. This is essential for experiments requiring accurate measurements, such as titrations or dilutions.

---

18. Balance Scale

- Name: Balance Scale (Triple Beam Balance)
- Usage: Scientists use balance scales to measure the mass of objects accurately. This is important for experiments where precise measurements of substances are required, such as in chemistry or physics.

---

19. Ruler

- Name: Ruler
- Usage: Scientists use rulers to measure lengths, distances, or dimensions of objects. This tool is essential for experiments involving geometry, mechanics, or any field requiring precise linear measurements.

---

20. Thermometer

- Name: Thermometer
- Usage: Scientists use thermometers to measure temperature. This is critical in experiments involving chemical reactions, physical changes, or environmental studies where temperature plays a key role.
