Scientific Method
A tentative explanation for scientific phenomena that must be tested in experiments to prove that it is true
What is Hypothesis
The title of a graph comparing the growth of bacteria A and the growth of bacteria B
What is "Growth of Bacteria A vs B"
The metric unit of mass, which can be estimated to be about as much mass as a paperclip
What is Gram
A variable that is the cause in the relationship explored in the experiment. Usually plotted on the x-axis of a graph.
What is Independent Variable
The basic unit of living things
What is Cell
Anything detected with the senses, typically called the start of the scientific investigation, and may be used to form questions and hypotheses.
What is Observation
A scientist is recording the growth of populations in a particular ecosystem. They depict the recorded data on a line graph. What should the x-axis represent?
What is months or years
5.75 m = _________ cm
What is 575 cm
A variable whose value is the effect of the experiment. It is usually plotted on the y-axis.
What is Dependent Variable
The sum of all chemical reactions in a cell
what is Metabolism
A known explanation of scientific phenomena, which has been proven to be true through continuous experimentation
What is Theory
A visual aid, best for conveying data in the form of percentages
What is Pie Chart
The metric base unit of distance
What is Meters
The constant and unchanging standard of comparison in scientific experimentation
What is Control
An example of this characteristic is a caterpillar becoming a butterfly
What is Growth and Development
A known explanation of scientific phenomena that has a mathematical relationship associated with it
What is Law
During a biology experiment studying the effect of fertilizer on the growth of tomato plants, a student records a chart comparing the height of a plant with fertilizer and a plant without fertilizer every day for a week.
The height of the plant should be plotted on which axis of a graph?
What is Y-axis
The instrument that should be used if the lab directions ask you to measure to the nearest milliliter
A variable whose value cannot be updated or altered anywhere in your investigation
What is Constant Variable
A change in the genetic composition of a population over successive generations
What is Evolution
The final step in the scientific method
What is communicate results and repeat experiment
An experiment compares how a grape swells or shrinks when it is placed in different solutions. The starting mass of the grapes are recorded at the beginning of the experiment. One is placed in distilled water, and another is placed in salt water. At the end of the experiment, their masses are recorded again.
The best type of graph to display the recorded data in this experiment is
What is Bar Graph
The curved surface of liquid in a graduated cylinder, of which you must read the mark at the bottom of the curve as the volume of the liquid
What is Meniscus
The results of the experiment will either support or refute this
What is Hypothesis
The reason cold blooded animals sit in the sun
What is Maintain Homeostasis
