Sci. Method 1
The first step of the scientific method.
What is determine the problem / ask a question?
A testable prediction.
What is a hypothesis?
These two atoms make up a molecule of water.
Hydrogen (2) and Oxygen
The specific temperature that freezes water.
32 degrees F or 0 degrees C
Information and observations collected during an experiment.
What is data?
Term for organisms that are active at night.
What is nocturnal?
Testing the hypothesis with a step-by-step procedure. (This is the fun part!)
What is an experiment?
The steps scientists follow during an experiment.
What is the procedure?
The term we use to describe water sticking to itself.
Cohesion
This atom on a water molecule is slightly positive.
Hydrogen
This variable is located on the Y-axis. (Hint: It is the variable you measure in an experiment.)
What is the DEPENDENT VARIABLE?
This mammal lays eggs.
What is a platypus or echidna?
The part or group in an experiment that is not tested or changed and is used for comparison.
What is the control (group)?
Looking at the world and using the five senses to make a prediction for an experiment.
What is an observation?
This atom on a water molecule has a dense electron presence and is slightly negative.
Oxygen
The term we use for water sticking to other molecules.
Adhesion
This type of graph is used to show relationships between two variables, typically showing how one variable changes in relation to another, often over time.
What is a LINE GRAPH?
The largest organ of the human body.
What is skin?
This type of variable is measured during an experiment.
What is the Dependent Variable (DV)?
Summarizes the experiment and states whether the hypothesis is accepted or rejected.
What is the conclusion?
The term we use to describe how water is good at DISSOLVING most substances (ex: salt, sugar, etc.)
Solvent or Universal Solvent
Water's cohesion is so strong that it creates THIS property of water that allows bugs to walk on water.
Surface Tension
This variable is located on the X axis. (Hint: it is the manipulated variable.)
What is the INDEPENDENT variable?
This part of a plant relies on sunlight to perform photosynthesis.
What are the leaves?
Parts of an experiment that are held the same between all variables/groups.
Constants
This type of variable is changed/manipulated during an experiment.
What is the Independent Variable (IV)?
212 degrees F or 100 degrees C
The term we use to describe the slight positive and negative charge of a water molecule.
Polar
The acronym that you learned in class to help you remember all the necessary parts of creating a graph.
TAILS (Title, Axis, Intervals, Labels, Scales)
or
DRY MIX
(Dependent,Responding,Y-axis)
(Manipulated,Independent,X-axis)
Term used for a group of alligators.
What is a congregation?
