Objectives for Unit 1 – Introduction to Science & the Scientific Method
You will UNDERSTAND the following concepts…
- Science is important to advance our country in technology, medicine, and research. It is the study of learning about the world around us.
- The metric system is the measurement system we use in science, as well as most other countries around the world. It is based on 10’s.
- Tools allow us to accurately measure objects. Scientific tools include the triple beam balance, graduated cylinder, beaker, thermometer and many more.
- Graphing allows us to put information into an easier “picture” form.
- Practicing lab safety and understanding the rules of the laboratory are extremely important.
You will KNOW the following ideas and concepts…
- The scientific method is a set of steps that scientists generally follow when carrying out a controlled experiment.
- A hypothesis is an educated guess. It is a possible solution to the problem that a scientist tests out.
- A controlled experiment contains a minimum of two set-ups. In a controlled experiment, a scientist will keep all variables the same (controls/constants) except the one variable they are testing.
- A variable is a factor in an experiment (ex: amount of sunlight, temperature of room, etc..).
- The independent variable is the factor being manipulated or tested by the experimenter. In a good controlled experiment, only one variable is tested at a time.
- The dependent variable is the factor being measured or analyzed. It is also called the responding variable.
- In order for an experiment to be valid, it must be tested over and over again by many different scientists.
You will BE ABLE TO DO the following activities…
- Design a controlled experiment
- Compare and contrast results
- Use scientific tools of the classroom to measure different objects
- Practice lab safety at all times
