The Nature of Science
Key Concept
Observable
Science studies the natural world using our senses and tools to collect data.
✓ Real-world events
Testable
Scientific ideas must be tested through controlled experiments and trials.
✓ Repeated trials
Changeable
Scientific knowledge grows and changes whenever new evidence is discovered.
✓ Updated with proof
Takeaway: Science is not a set of static facts; it is a way of knowing based on evidence.
Forming a Testable Hypothesis
Formula
The "If... Then... Because..." Structure
IF [Action]
What the scientist changes (Independent Variable)
THEN [Prediction]
What will happen & be measured (Dependent Variable)
BECAUSE [Reason]
The scientific principle explaining why
Example in Action
If a plant receives 8 hours of direct sunlight, then it will grow taller than a plant in shade, because sunlight provides energy for photosynthesis.
Remember: A hypothesis must always be clear, specific, and measurable! Step 1 in scientific design
The 3 Types of Variables
Investigation Core
INDEPENDENT VARIABLE (IV)
"I Change It"
The ONE factor intentionally modified by the experimenter.
Plant Example: Amount of fertilizer added (0g, 5g, 10g)
DEPENDENT VARIABLE (DV)
"Data Measured"
The outcome or response that is observed & measured .
Plant Example: Height of plant in centimeters (cm)
CONTROLLED CONSTANTS
"Keep Constant"
All other conditions kept identical across every test group.
Plant Example: Same soil type, same water, same pot size
Rule of Fair Testing: Change only ONE independent variable at a time so you know what caused the result!
CER Framework for Scientific Explanations
Writing Science
C
Claim
A direct statement that answers the original research question.
Sentence Starter: "The data shows that..."
E
Evidence
Specific scientific data, measurements, and recorded numbers that support the claim.
Sentence Starter: "Specifically, group A had..."
R
Reasoning
The scientific principle explaining why the evidence proves the claim.
Sentence Starter: "This occurs because..."
Claim + Evidence + Reasoning = Complete Scientific Argument

1 The Nature of Science
1. Scientific investigations must be , meaning they rely on information gathered through our five senses and measurement tools.
2. An explanation is only scientific if it is through repeated trials and controlled experiments.
3. Scientific knowledge changes when new is discovered and verified by other scientists.
2 Hypotheses and Experimental Variables
The "If... Then... Because..." Formula:
IF: The independent variable that I change.
THEN: The prediction / what is measured.
BECAUSE: The biological reason or fact.
Variable Type Definition & Memory Hook Plant Experiment Example (IV) The factor that "I" change deliberately. A fair test only tests IV at a time. Amount of liquid fertilizer added per day (mL). (DV) The factor that is measured as data to see the effect. Final plant height in centimeters (cm). (Controlled) Conditions kept across all groups so the test is fair. Same soil type, same sunlight, same pot size.
