Experimental Setup
In an experiment, this is the 'manipulated variable' - the variable that the scientist can change
What is the independent variable?
The basic unit of all living things (can be made of one of these or more than one)
What is a cell?
The most basic unit of matter
What is an atom?
This part of a microscope is where you place a slide to observe it (see microscope at front of room)
What is the stage?
The ability of an organism to maintain a relatively constant internal environment despite changes in the outside
What is homeostasis?
In an experiment, this is the 'responding variable' - the variable that scientist measures in an experiment
What is the dependent variable?
The branch of science that studies life
What is biology?
The negative part of an atom
What is an electron?
This term means 'made of one cell'
What is unicellular?
This part of the cell controls what enters and leaves a cell
What is the cell membrane?
What is observation?
A characteristic of life that means to 'get bigger' or to 'change over time'
What is growth and development?
This carbon compound is used for short term energy
What is a carbohydrate?
This part of a microscope contains tubes that magnify a specimen by 4x, 10x, and 100x (see microscope up front)
What is the objective lenses?
This level of organization comes after 'tissues' in multicellular organism
What is an organ?
In the scientific process, this is a scientific explanation for a set of observations that can be tested in ways that support or reject it
What is a hypothesis?
The process of maintaining a stable, internal environment
What is homeostasis?
This is the monomer of a protein
What is an amino acid?
This part of a cell that directs a cells activities and contains DNA
What is the nucleus?
This is the process in which materials move from high concentration to low concentration, directly across a semipermeable membrane
A scientist expects that, if you place crystals of copper sulfate into hot water, then the crystals will dissolved faster than in cold water. This would be the independent variable for this research project.
What is the temperature of the water?
What is metabolism?
This reagent is what we used to test for multiple sugars
What is Benedict's reagent?
The part of a cell that creates proteins
What is the ribosome?
This is what occurs when to a 'cell' placed in corn syrup and why it happens
What is shrink because water molecules move out by the process of diffusion?
