Fire is a by-product of a rapid combustion reaction. Qualitative Observation - Using words to describe something that you are seeing in your experiment.
A liquid forms a pool, flows or runs but it can't be stretched or squeezed.
Children learn about them as part of their study of teeth and how to take care of them. Subscribe to America's largest dictionary and get thousands more definitions and advanced search—ad free! It is often referred to as the 'brain' of a cell because it contains the genetic instructions.

Consumers are also called predators of the animals they eat; animals eaten by other animals are prey. Once there is sufficient oxygen and fuel for the fire to grow and spread, the fire has reached the Steady-State Burning Phase.
Objects made of metal are good conductors.
Depending on its temperature, matter can change state; heating, cooling, evaporating and condensation are ways in which a material changes state. Depending on how fast or slowly something vibrates a sound's pitch with be high or low. Photosynthesis - This is the process plants use to convert sugar and carbon dioxide into energy. Young, G. I. M. (1970). Having a control allows you to measure your results so that you know how much a variable has changed in an experiment. The four seasons (autumn, winter, spring, summer) we experience on our planet are caused by the Earth's tilt as it rotates around the Sun. One byproduct of photosynthesis is oxygen.
Evolution - The process by which species change to adapt to their environment. These terms are basic to any experiment you design.
Incipient Phase: Also scientific computing and scientific computation (SC). Magnetic force is an invisible force created by electrons.
Flammable or Explosive Limits In primary school children learn about simple series circuits in which a single wire runs from a battery to a bulb and back again.
A food chain is a diagram that shows us how animals are linked by what they eat. Condensation is to turn from a gas into a liquid. "C++ FAQ: "What's this "serialization" thing all about? For every action, there is an equal and opposite reaction. Atomic number - This is the number of protons in an atom. For example, a water molecule is made up of two hydrogen atoms and one oxygen atom. Incisors are teeth used for biting and cutting food. Within a food chain, a producer (usually a green plant) passes energy on to a consumer (an animal who eats the plant) through carbohydrates and proteins.
Momentum - The product of mass times velocity. Base - A base is higher than 7 on the pHscale and turns red litmus paper blue. Friction - How surfaces interact with one another or the measure of resistance felt when one surface slides against another. Recessive Trait - When two alleles of the same gene expression are present. This glossary of computer science is a list of definitions of terms and concepts used in computer science, its sub-disciplines, and related fields, including terms relevant to software, data science, and computer programming Welcome to the Online Science Dictionary. Examples of bases include things like lye (for soap making), Tums or milk of magnesia. Matter makes up our planet and the whole universe. Fusion - The joining together of two atomic nuclei. Nucleus - That part of an atom containing the protons and neutrons.
The method by which heat is transferred via direct contact or a conduit.
These are the literal building blocks for most of your scientific inquiries. Inertia is the tendency for a body to stay at rest when it is at rest, or to keep moving if it is moving, unless an outside force acts upon said body. Examples of simple machines are levers, gears, pulleys, wheels and screws. Genotype - The genetic makeup of an individual. Brush up on your own science knowledge, clear up homework confusion and understand exactly what your child is learning at school by reading our basic definitions (with links to more detailed explanations, teachers' tips and examples). B) Class B fires involve flammable and combustible liquids, and/or gases such as gasoline, paint, alcohol and related substances. 5.

A magnet's north pole is the end of the magnet attracted to the Earth's North magnetic pole; a magnet's south pole is the end of the magnet attracted to the Earth's South magnetic pole. A proposal for a formal definition of the design concept.
