The "sol"ution
100
This is an organized way using evidence to learn about only the natural world. This proposes explanations that can be tested with evidence. This is the body of knowledge that scientists have built up after years. This includes all living things composed of matter. Matter is made of molecules. Molecules are made of atoms (choices: Science, Observation, Data, Inference, Hypothesis)
What is science
100
This is the now disproven theory that life could arise from nonliving matter
What is spontaneous generation
100
This microscope allows light to pass through a specimen and uses two lenses to form an image. Its limit is 0.2 micrometers
What is a compound light microscope
100
These two elements, in this ratio, make up water
What is 2 hydrogens to every 1 oxygen
100
This is a substance that is dissolved in a solvent to make a solution
What is a solute
200
This is the use of the senses to gather information (choices: Science, Observation, Data, Inference, Hypothesis)
What is observation
200
This is the factor in an experiment that the scientist changes and is also known as the manipulated variable
What is the independent variable
200
This microscope forms an image by shining beams of light THROUGH a thin specimen. It must be in a vacuum.
What is a transmission electron microscope
200
Attraction between molecules of the same substance, as in the attraction that holds water molecules to water molecules is called
What is cohesion
200
This is a substance in which a solute is dissolved to form a solution
What is solvent
300
This is evidence or information gathered from observations of 2 Kinds quaNTitative or quaLitative. (choices: Science, observation, data, inference, hypothesis)
What is data
300
This is the factor in an experiment that a scientist wants to observe. This may change in response to the manipulated variable. This is also known as a responding variable
What is the dependent variable
300
This microscope scans a narrow beam of electrons back and forth across the surface of a specimen. It produces realistic, and often dramatic, three-dimensional images of the surfaces of objects.
What is a scanning electron microscope
300
This type of bond is responsible for allowing water to be VERY cohesive or VERY capable of one water molecule being attracted to another water molecule
What is cohesion
300
The Latin name of the main-sequence star
What is sol
400
This is a logical interpretation based on prior knowledge and experience (Choices: Science, Observation, Data, Inference, Hypothesis)
What is inference
400
This is the ideal number of variables which should be changed at one time in a controlled experiment
What is one
400
This light microscope uses a computer to recreate an image of the specimen seen by light and often tagged with fluorescence. The image is generated with the use of light.
What is confocal light microscope
400
This is a type of attraction between molecules of different substances and is responsible for capillary action (how water travels up a plant)
What is adhesion
400
This is one of the four fundamental states of matter (the others being liquid, gas, and plasma). It is characterized by structural rigidity and resistance to changes.
What is a solid
500
This is a possible explanation for a set of observations. This is a possible answer to a scientific question. This is tested by controlled experiments or gathering data. Some are ruled out. Some are supported and confirmed (Choices: Science, Observation, Data, Hypothesis, Inference)
What is hypothesis
500
This is an act performed by the hydra where a single parent reproduces by itself
What is asexual reproduction
500
This microscope is used to see a single atom
What is a scanning probe microscope
500
This is the complete answer for the type of bond found inside a single water molecule. It represents the sharing of electrons, and they are shared in an uneven fashion.
What is polar, covalent
500
This is the process of placing a solid substance into a solvent to make a solution
What is dissolve
