What is the first step in the scientific method?
Identify a problem.

True or False: Collecting data is the final step of the scientific method.
FALSE! After data is collected, the last step is to form a conclusion.
What is cellular organization?
Organisms have many different cells with specialized functions- muscle cells on one place, eye cells in one place, etc.
What is homeostasis?
To use this microscope you coat the specimen in a thin coating of metal then a narrow beam of electrons is passed over the surface of the specimen producing a 3D image.
Scanning Electron Microscope
What is the control group in an experiment?
This is the group that is not being tested and is used for comparison.
For example, if an experiment is testing the effect of using different liquids ( one plant is fed gatorade, another is given coffee, another is given soda, and te last one is given juice) to water plants, the control would be the plant that is given just regular water.
