Study Notes
Science Experiments
- Science experiments are structured processes used to test hypotheses and understand natural phenomena.
- Experiments are crucial for discoveries in various fields like medicine and technology.
- Scientists systematically manipulate variables to observe their effects.
The Scientific Method
- The scientific method is a series of steps used in all scientific experiments.
- The process involves observation, research, hypothesis formation, experimentation, data analysis, and conclusion.
- Following a sequence of steps helps to ensure accurate results.
Variables in Experiments
- Experiments involve variables, which are factors that change.
- Independent variables are factors manipulated by the scientist.
- Dependent variables are factors measured as outcomes.
- Controlled variables are factors held constant to isolate the effects of the independent variable.
- Maintaining consistent controlled variables is key to accuracy.
Control Groups in Experiments
- A control group is used as a baseline for comparison with the experimental group.
- Controls ensure any observed effects are due to the independent variable and not chance.
- In drug testing, a placebo (a sugar pill) would be a common control.
- Comparing experimental & control group results is vital when determining drug effectiveness.
