What is Science?
- Science is the study of phenomena and events in nature
- Science is based on evidence
- Scientific knowledge is subject to change
- Scientific knowledge has limitations
- Scientific discoveries have led to inventions that improve our quality of life
- Science can help us manage natural resources more effectively

Scientific Investigations
- Scientific Investigations usually follow these steps:
- Making observations
- Asking questions
- Proposing hypotheses
- Doing experiments
- Drawing conclusions
- A fair test has 3 kinds of variables:
- Independent variable is the variable that is changed
- Dependent variable is the variable that is measured
- Controlled variables are the variables that are kept the same
- There are many types of scientific investigations, including:
- Fair testing
- Pattern seeking
- Classifying
- A laboratory is an appropriate place for conducting scientific investigations
Safety Rules
- Follow your teacher’s instructions
- Do not enter the laboratory or perform experiments without your teacher’s permission
- Keep exits and passages clear
- Do not eat, drink, run, or play in the laboratory
- Keep the laboratory clean and tidy
