2) Form of Hypothesis- a statement about what you think is the answer to your problem (in an if, then statement)
3) Design an experiment- gathering our materials, making a procedure, and testing our hypothesis
4) Record and analyze data- writing down all your measurements
5) Draw a conclusion- you compare your data with your hypothesis
6) Control- is what it is used to compare in the experiment
Animal Kingdom:
1) Extinction- Is when there isn't a kind of animal. There are no more of one species. The entire species is gone
2) Adaptation- a trait that increases the ability of an organisms to survive in its environment
