|
Steps
|
•defining a problem
•forming a hypothesis and making predictions •planning an investigation •identifying variables •collecting and organizing data •interpreting data and analyzing information •drawing and defending conclusions |
|
Description
|
•after making observations or reading
•forming an hypothesis, are making an educated guess •decide whether to be in field work or laboratory •identify other variable to be controlled •must be recorded and properly organized •analyze the information •investigate the hypothesis |
|
Atomic theory
|
The current theory shows atoms as having smaller parts when the old theory described atoms as tiny, marble like spheres which is incorrect
