Scientific Method - systematic approach to problem solving in science.
The basic steps in the scientific method are:
- Stating the problem
- Gathering information on the problem
- Forming a hypothesis
- Performing experiments to test the hypothesis
- Recording and analyzing data
- Stating a conclusion
- Repeating the work
Hypothesis - a proposed solution to a scientific problem.
Variable - the one factor that is being tested in an experiment
Manipulated variable - the one factor that a scientist changes during an experiment.
Responding variable - the variable that is expected to change in response to the manipulated variable.
Control - experiment run without a variable in order to show that any data from the experimental setup were due to the variable being tested.
Data - recorded observations and measurements.
Lab Safety
The most important laboratory safety rule is to always follow your teacher's directions or the directions in your textbook exactly as stated.
