Rates of Reaction
This is how fast a reaction takes place
What is rate of reaction
This a movement that takes the Earth approximately 365.25 days to complete one of these around the Sun
What is a revolution (or orbit)
This is a square frame and is thrown randomly to sample areas and count plant populations in a habitat.
What is a quadrat?
This unit, named after a famous Italian physicist, is used to measure the electrical potential difference or voltage.
What is the Volt (V)?
This subatomic particle has a negative charge and whizzes around the outside of the atom's nucleus in shells.
What is an electron?
This is crushing a solid into a powder increases this property
What is surface area?
This event occurs when the Moon passes directly between the Sun and the Earth, temporarily blocking out the Sun's light.
What is a solar eclipse?
This is non-living factor, such as soil pH, temperature, and rainfall, heavily influence where organisms can live.
What is abiotic (or environmental) factors?
This does not allow electricity/heat to flow.
What is an insulator?
This number, found on the periodic table, tells you the exact number of protons inside the nucleus of an atom.
What is the atomic number?
This is the number of particles in certain volume
What is concentration?
These periodic rises and falls of large bodies of water are primarily caused by the gravitational pull of the Moon and the Sun.
What is tides?
This is simple diagram shows the direct transfer of energy as one organism eats another, always beginning with a producer.
What is a food chain?
This is a circuit arrangement, there is only one single path for the current to flow, meaning if one bulb blows, they all go out.
What is a series circuit?
This is the chemical formula for water, indicating the number and elements contains
What is H2O?
What is an enzyme?
This term describes the phase of the Moon when it is completely in the Earth's shadow, making it invisible in the night sky.
What is a New Moon?
This term describes a community of living organisms interacting with the non-living parts of their environment.
What is an ecosystem?
This scientific law states that voltage is equal to current multiplied by resistance (V = I x R).
What is Ohms law?
This term describes the combining power of an element, which tells us how many electrons an atom wants to gain, lose, or share to become stable.
What is valency?
This is a theory where particles must collide with each other with sufficient energy
What is collision theory
This is how the Earth experiences seasons because its axis is tilted at this specific angle relative to its orbital plane.
What is 23.5 degrees?
This is refers to green plants. This title in a food chain because they can make their own food using sunlight through photosynthesis.
What is a producer?
This describes when the line graph goes through the origin (0,0) and is a straight line.
What is directly proportional?
Using the "crossover method" with valencies, this is the correct chemical formula for magnesium chloride, made from Mg (valency 2) and Cl (valency 1)
What is MgCl2?
