Looking for science words that start with B? You’ve come to the right place.

From Biosphere to Black hole, the subject I loved most at school – there are some awesome science-related words beginning with the letter B.

Here is a list with some words beginning with B that are commonly used in science:

Biology – the scientific study of living organisms, including their structure, function, growth, evolution, and interaction with each other and their environment.

Biotechnology – the application of technology to living organisms, especially in the fields of medicine, agriculture, and industry, to produce useful products or solve problems.

Biosphere – the part of the Earth’s surface and atmosphere where living organisms exist, including all plants, animals, and microorganisms, and their interactions with each other and with their physical environment.

Bacterium -a single-celled microorganism that belongs to the domain Bacteria, which can exist as either independent organisms or as parasites, and can have positive, negative, or neutral effects on their host organisms.

Binary – a numbering system that uses only two digits, typically 0 and 1, to represent numbers and perform operations in digital computing.

Black hole – a region of spacetime where gravity is so strong that nothing, including light, can escape its pull, and where the laws of physics as we know them may break down.

Big bang – the cosmological model that describes the early development of the universe, starting from a single point of infinite density and temperature, and expanding rapidly in a process of inflation that continues to this day.

Bond – a chemical connection between two or more atoms that forms as a result of the sharing or transfer of electrons, and that determines the properties and behavior of molecules and compounds.

Blastula – a hollow ball of cells that forms during the early development of many animal embryos, and that eventually gives rise to more specialized cells and tissues.

Butterfly effect – the idea that small changes in initial conditions can lead to large and unpredictable outcomes in complex systems, such as weather patterns or financial markets.

Bernoulli’s principle – the physical law that describes the relationship between fluid velocity and pressure, stating that as the velocity of a fluid increases, its pressure decreases, and vice versa.

Biogenesis – the principle that living organisms arise only from other living organisms, rather than from non-living matter.

Blue shift – the phenomenon in which light from a source appears to shift towards the blue end of the spectrum, indicating that the source is moving towards the observer.

Broad-spectrum – this describes a substance or treatment that is effective against a wide range of pathogens or conditions, rather than targeting a specific type or strain.

Bronchus – one of the two main branches of the trachea that lead to the lungs, and that are responsible for the passage of air in and out of the respiratory system.

Brachiation – the method of movement used by some primates, such as gibbons, in which the animal swings from branch to branch using only its arms.

Bremsstrahlung – a type of radiation that is produced when a charged particle, such as an electron, is decelerated by the electric field of an atomic nucleus. Bremsstrahlung radiation is a form of electromagnetic radiation that can range from radio waves to gamma rays. It is commonly used in medical imaging and radiation therapy.

Buffer – a solution or substance that can maintain a stable pH level when added to an acidic or basic solution. Buffers are important in many biological processes, as they help to regulate the pH of the body’s fluids and prevent fluctuations that can disrupt normal cellular function.

Buoyancy – the upward force exerted by a fluid, such as water or air, on an object immersed in it. Buoyancy is dependent on the density of the fluid and the volume of the object, and is responsible for the ability of some objects to float in water or air.

Byte – a unit of digital information that typically consists of eight bits. Bytes are commonly used to measure the size of computer files and the amount of data transmitted over networks.

Base – a substance that can accept hydrogen ions (protons) in a chemical reaction, and is therefore considered to have a pH greater than 7. Bases are important in many chemical and biological processes, and are commonly used in medicine and agriculture.

Bathymetry – the measurement and mapping of the ocean floor and other underwater terrain. Bathymetry is important in oceanography, marine geology, and other fields that study the ocean and its inhabitants.

Biosynthesis – the process by which living organisms produce complex organic compounds from simpler molecules. Biosynthesis is an important part of many biological processes, such as metabolism and protein synthesis.

Bit – the basic unit of digital information, representing a single binary digit of either 0 or 1. Bits are used to store and transmit information in computers and other digital devices.

Bremsstrahlung radiation – a type of electromagnetic radiation that is produced when a charged particle, such as an electron, is decelerated by the electric field of an atomic nucleus. Bremsstrahlung radiation is commonly used in medical imaging and radiation therapy.

Brainwave – the electrical activity that is generated by the brain and can be measured using electroencephalography (EEG). Brainwaves are important in neuroscience and are used to study brain function and activity.

Biodegradable – capable of being decomposed by living organisms, such as bacteria or fungi. Biodegradable materials are often used in products that have a reduced environmental impact, such as biodegradable plastics.

Blastocyst – a hollow ball of cells formed early in the development of mammals, consisting of an outer layer of cells and an inner cell mass.

Beta particle – a high-energy electron or positron emitted by certain types of radioactive decay.

Brackish – this water that is slightly salty, usually a mixture of seawater and freshwater.

Bragg’s law – a principle in X-ray crystallography that relates the spacing of atoms in a crystal lattice to the angles at which X-rays are diffracted.

Binary fission – a type of cell division in which a single cell divides into two identical daughter cells.

Biochemistry – the study of chemical processes and substances in living organisms.

Bioluminescence – the production of light by living organisms, often as a result of chemical reactions within the organism.

Botany – the scientific study of plants, including their physiology, structure, and classification.

Benthic – this is referring to the bottom of a body of water, including the organisms and ecosystems that live there.

Bioinformatics – the application of computer science and statistics to the analysis of biological data, such as DNA sequences.

Basalt – a type of volcanic rock that is dark in color and has a fine-grained texture.

Bacteria – a type of single-celled microorganism that is found in a wide range of environments and can be both harmful and beneficial to humans.

Biome – a large community of plants and animals that occupies a distinct geographic region.

Biodiversity – the variety of life in a particular ecosystem or on Earth as a whole.

Barometer – an instrument used to measure atmospheric pressure.

Beta decay – a type of radioactive decay in which a nucleus emits a beta particle.

Bromine – a chemical element that is a dark red liquid at room temperature and is used in a variety of applications, including flame retardants and water purification.

Birefringence – the property of some materials to split a beam of light into two separate beams with different polarizations.

Boltzmann constant – a fundamental constant of nature that relates the energy of a system to its temperature.

Brønsted-Lowry acid-base theory – a theory of acid-base reactions that defines an acid as a proton donor and a base as a proton acceptor.

Buoyancy – the upward force exerted by a fluid on an object immersed in it.

Baryon – a type of subatomic particle that is made up of three quarks.

Bayesian inference – a statistical method for updating probabilities based on new information.

Basal metabolic rate – the rate at which an organism uses energy while at rest.

Biodistribution – the process by which a drug or other substance is distributed throughout the body.

Biomineralization – the process by which living organisms produce minerals, such as the shells of mollusks or the bones of vertebrates.

Biotic potential – the theoretical maximum rate at which a population of organisms can increase in size under ideal conditions, given unlimited resources and freedom from predation and disease.

Bioreactor – Bioreactors provide a controlled environment for cell growth, allowing researchers to optimize conditions such as temperature, pH, and nutrient availability.

Bryophyte – a group of non-vascular plants that includes mosses, liverworts, and hornworts.

Brownian motion – the random movement of small particles suspended in a fluid, caused by collisions with molecules in the fluid.

Botulinum toxin – a neurotoxin produced by the bacterium Clostridium botulinum, which can cause a severe and potentially fatal form of food poisoning known as botulism.
