The goals of science
1.Understand the natural world
2.Explain natural phenomena
3.Use explanations to make predictions
4.Apply scientific knowledge to solve problems
Levels of organization
1.Atom
2.Molecule
3.Organelle
4.Cell
5.Tissue
6.Organ
7.Organ system
8.Organism
Scientific method/protocol
1.Observation-noticing a phenomenon
2.Question-what are you curious about
3.Hypothesis-testable explanation
4.Prediction-what would happen if the hypothesis was correct
5.Experiment-controlled test
6.Data collection-gather results
7.Analysis-interpret data
8.Conclusion-support or reject hypothesis
9.Communication- share results
,Qualitative vs Quantitative data
-Descriptive, non numerical -Numerical, measurable
-Color, texture, behavior -Height, mass, temperature
Graphing & Variables
-Independent Variable (IV): what you change
➜ goes on the x-axis
-Dependent Variable (DV): what you measure
➜ goes on the y-axis
-Control Group: standard for comparison
-Data collection: careful, repeated measurements
-Interpretation: explain what the graph shows
Characteristics of Living Things
All living things:
1.Are made of cells
2.Have DNA
3.Use energy (metabolism)
4.Respond to stimuli
5.Maintain homeostasis
6.Grow and develop
7.Reproduce
8.Evolve over time
Scientific Thinking
, -Observation: using senses to gather information
-Inference: logical explanation based on observations
-Hypothesis: testable explanation
-Prediction: expected outcome
-Evidence: data supporting or refuting a claim
-Bias: personal belief influencing results
-Technology: application of scientific knowledge
-Biology: study of life
Experiments & Data
-Controlled Experiment: only one variable changed
-Independent Variable: manipulated factor
-Dependent Variable: measured result
-Control Group: no experimental change
-Quantitative Data: numerical
-Qualitative Data: descriptive
Scientific Knowledge
-Theory: well-tested explanation
-Law: describes a consistent natural pattern
Life Processes
-DNA: genetic material
-Metabolism: chemical reactions in cells
-Stimulus: environmental change
-Homeostasis: stable internal conditions
