What is "All living cells come from other cells"
"I have two eyes"
What is an example of truth learned through direct observation?
A "educated guess" at an explanation for a specific natural phenomenon, which is based on your understanding of the available science, and which can be tested using an experiment
What is a hypothesis
Imprecise measurement instruments and confounding variables, and unexpected sources of error all make this step in the scientific method difficult.
Why is it difficult to analyze experiments? (or What is analysis?)

The tool that Van Leeuwenhoek built in order to observe very small organisms
Ripley Has a Tail
Therefore Ripley is a Tiger
What is an example of invalid logic?
A mental model that represents some part of the natural world, is supported by a great deal of evidence, and accounts for all related scientific facts
What is a scientific theory?
This group gives us something to compare our experimental results to, in order to determine if the results are significant
What is the control group?

What is an observation of how Living things are organized into cells?
The French chemist who performed and experiment showing that bacteria cells come from other bacteria cells

The Six Characteristics of Life
What are Living things are Organized into Cells, Gather Matter and Energy, Grow Develop and Reproduce, Use and Pass on Genetic Information, Respond to their environment, Adapt to their environment
The three key propositions of Cell Theory
What are:
All living things are made of cells
All cells come from other cells
The cell is the smallest unit of structure in all living organisms. Cells perform the functions of life.
The three ways in which we can know truth
What are:
Direct Observation
Divine Revelation
Valid Logic
What are Theory, Hypothesis, Experiment, Analysis?
1) Review our experimental methods for accuracy and precision of measurements
2) Review our hypothesis to ensure that it accurately reflects the consequences of our Theory
3) Review, modify, or replace our Theory
