Formulating a Viable Scientific Hypothesis

1. Formulating a Viable Scientific Hypothesis

Constructing a viable scientific hypothesis involves several different factors. In this lesson, you'll explore what separates a good hypothesis from a bad one and how to identify if your hypothesis has been formulated properly.

How Scientific Observations Lead to Scientific Questioning

2. How Scientific Observations Lead to Scientific Questioning

Scientific observations are a major component of the scientific process because they lead scientists to ask questions about the world around them. These questions may then be refined with continued observation, or they may be tested through experimentation.

The Iterative Nature of the Scientific Method

3. The Iterative Nature of the Scientific Method

The scientific method is a process of steps that scientists follow, but as you move through them you may want to repeat or revisit specific ones. In this way, we can see how both the scientific method and its components are iterative.

Identifying Potential Hypotheses from a Given Experiment

4. Identifying Potential Hypotheses from a Given Experiment

Experimental designs are dependent on good hypotheses. But we can also look at it the other way and identify a hypothesis from an experiment. In this lesson, we'll work through this process, showing you how to dissect an experiment to identify what is being tested.

Designing an Experiment to Test a Given Hypothesis

5. Designing an Experiment to Test a Given Hypothesis

A well-written hypothesis is the key to any well-designed experiment. In this lesson, we'll work through the process of designing an experiment based on the hypothesis it's meant to test and see how the two work to complement each other.

Understanding Whether Experimental Designs Match Hypotheses

6. Understanding Whether Experimental Designs Match Hypotheses

Hypotheses and experimental design are two peas in a pod. How you write your hypothesis will greatly influence how you design your experiment. In this lesson, learn about the types of experiments you may run and how you can match your hypothesis to the appropriate one.

What is Conduction in Science? - Definition & Examples

7. What is Conduction in Science? - Definition & Examples

How does water boil? Why do lights come on when we flip the switch? These normal occurrences are made possible by a process called conduction. In this lesson, we will talk about conduction and some examples.
