A condenser is a laboratory device used to cool and condense vapors back into liquid form. It typically consists of a tube through which vapor passes, surrounded by a layer of cold water that cools the vapor as it moves through. The cooled vapor then turns back into liquid and can be collected in a separate container. Condensers are commonly used in distillation processes, where heat is applied to a liquid to separate its components, and in other experiments that involve heating and cooling substances. The cold water helps ensure the vapor does not escape.

A map is a flat representation of a geographic area, showing features like mountains, rivers, roads, cities, and bodies of water. It helps people understand the layout of a place and navigate from one location to another. Maps can vary in detail, with some focusing on large areas like countries or continents, while others show smaller regions, such as cities or neighborhoods. They often use symbols and colors to represent different types of land, infrastructure, or landmarks. Maps are useful tools for travel, planning, and learning about the world.

A thematic map is a type of map that focuses on a specific topic or feature of an area, rather than showing general geographical details. It highlights information such as population, climate, natural resources, or language distribution. Thematic maps use colors, symbols, or patterns to make the data easier to understand and interpret. These maps are often used to show trends, compare data, or analyze certain aspects of a region, making them useful in fields like geography, economics, and social studies.

A globe is a three-dimensional model of the Earth, showing its continents, countries, oceans, and other geographical features. It is typically spherical in shape and is often mounted on a stand, allowing it to rotate like the Earth does. Globes provide a more accurate representation of the Earth's surface than flat maps because they show the true proportions and distances between places. They are commonly used for educational purposes, helping people understand the Earth's geography and how different locations relate to each other.

A compass is a small device used to show direction. It consists of a magnetic needle that always points to the Earth's magnetic north. Compasses are commonly used for navigation, helping people find their way when traveling in unfamiliar areas. The device typically has a circular dial marked with the four main directions—north, south, east, and west—and sometimes additional markings for more precise directions. Compasses are used in activities like hiking, boating, and map reading to determine orientation and guide movement.

A telescope is an optical instrument used to observe distant objects, such as stars, planets, and galaxies. It uses lenses or mirrors to gather and focus light, allowing the viewer to see objects far away in greater detail. Telescopes are commonly used in astronomy to study celestial bodies and in science to explore the universe. There are different types of telescopes, such as refracting telescopes, which use lenses, and reflecting telescopes, which use mirrors. Telescopes can be found in observatories or used for personal stargazing.
