EQ: What are the most effective ways to carry out a scientific inquiry?. Sometimes in science, events are so big (like the explosion of a volcano), or so small (like the movement of Euglena) or so distant (like the movement of a star) that it is impossible for our brains to understand them in their entirety..

Designing Investigations. 3 Kinds of Variables. Independent Variable – something that is changed by the scientist. What is tested. What is manipulated. 3 Kinds of Variables. Dependent Variable – something that might be affected by the change in the independent variable.

Variables start with lower case letter. Variables are descriptive of what they store . Variables are one word . Use camel case is two . myRate. ; . Data types - specifies the kind of data you are storing.
