Nature of Science
Dr. Mudnas performing the same experiment on physical properties of matter that Dr. Lizard performed is an example of this.
What is replication?
The universe is composed of many billions of these, each composed of billions of stars and planets.
What are galaxies?
Intensive properties such as density, conductivity, and reactivity do not change based on this.
What is the amount of a substance?
This is a kind of symbiotic relationship where one species benefits at the cost of the other, as between mosquitoes and deer.
What is parasitism?
This is a mass of incandescent gas, a gigantic nuclear furnace where hydrogen is built into helium at a temperature of millions of degrees.
What is the sun or a star?
George conducts an experiment where he changes the amount of vinegar he uses to make a model volcano with baking soda. He measures how long it takes the volcano to react. The amount of vinegar he uses is this type of variable.
What is independent?
When an axis of the earth is tilted towards the sun, this season results for the hemisphere closest to the sun.
What is summer?
The chemical equation 4 Al + 3 O2 --> 2 Al2O3 demonstrates this law.
What is the law of conservation of mass?
This microbiotic specimen causes sickness and is too small to be considered living. It hijacks cells and forces them to make more copies of it.
What is a virus?
They are tiny and they're teeny, much smaller than a beany. They never can be seeny. They make up the air. They're everywhere.
What are atoms?
This kind of model relies on ideas and analogies to allow better understanding of science.
What is a conceptual model?
This process involves laying down bits of rock or sediment which have been broken down by natural processes.
What is deposition?
This law developed by Sir Isaac Newton can be demonstrated by a person continuing to move forward when a car stops until they hit the windshield.
What is the law of inertia (Newton's 1st law)?
What is "an object in motion stays in motion until acted on by an outside force"?
The human body relies on this system to absorb nutrients from the food we eat.
What is the digestive system?
This is a solid collection of minerals.
What is a rock?
After many years and hundreds of experiments, many scientists think that depression is caused by interactions between the nervous system and the other body system, an example of this kind of scientific idea.
What is a theory?
This plastic-like layer of the mantle undergoes convection due to differences in the density of the molten rock.
What is the asthenosphere?
A phone battery allowing a phone to play music is an example of this kind of energy transformation.
What is chemical potential energy being transformed to the kinetic energy of sound?
If a woman who is homozygous dominant for the trait of free earlobes (EE) marries a man who is homozygous recessive for the trait of attached earlobes (ee), this is the phenotype of their offspring.
What is free earlobes?
Plants create their own food from these three things they need to stay alive.
What are water, sunlight, and carbon dioxide?
Dr. Litif is studying anxiety in mice. He performs an experiment to see how long the mice spend by the edge of a platform. He uses this step in the scientific method when he predicts mice given a certain drug will spend more time on the platform.
What is a hypothesis?
This causes the surface currents in earth's oceans.
What is wind?
Atoms arranged in the same column in a periodic table share these qualities because they have the same number of valence electrons.
What is properties and reactivity?
Carbon is taken in from the atmosphere by photosynthesis and released to the atmosphere by this process, which involves this chemical equation.
What is cellular respiration? C6H12O6 + 6 O2 --> 6 CO2 + 6 H2O
OR
sugar and oxygen react to yield carbon dioxide and water
In this, noble gases are stable, while halogens and alkali metals react aggressively.
What is the periodic table?
