disproved.
Compare and contrast between hypothesis and theory. -
Correct Answer ✅A hypothesis is a possible explanation for
a set of observations. A theory is a well tested explanation of

Write out examples of a theory. - Correct Answer ✅-
Evolution by natural selection
- Cell Theory
- Genetics and homeostasis
Compare and contrast Theory and Scientific Law. - Correct
Answer ✅A theory is a well tested explanation of a broad

Procedure - Step-by-Step, clear, specific and should be clearly
defined that a stranger could pick up your procedure and
replicate your experiment.
Collection of Data - Qualitative and Quantitative.
Analysis - Graphs, Charts, Diagrams, Descriptions or Pictures
(refer to graph checklist).
Conclusion - Summary of experiment, analysis of results,
hypothesis supported or rejected "explain" or "why" using
your data, error or problems that arise, and what are the next
steps moving forward (will you revise and start new?)
How can different bias arise in science and provide
examples? - Correct Answer ✅Scientists can take a

scientific data can be misinterpreted and misapplied by a
scientist who wants a certain outcome or "proof". ex: scientist

Answer ✅Independent Variable - the variable you are
changing. ex: amount of sunlight
Dependent Variable - responds to what you are changing. ex:
height of plants
