Lesson 12: Science Research & the STEM Pipeline
You've covered biology, chemistry, and physics. This final lesson ties it all together — how scientists actually do science, how STEM careers work in Oklahoma, and how to design your own research question.
Key Concepts
The Scientific Method (Advanced)
Hypothesis → Experimental Design → Data Collection → Statistical Analysis → Peer Review → Publication. Real science is iterative: negative results are valuable. Peer review catches errors before publication.
Controlled Experiments
A controlled experiment changes only one variable (independent variable), measures one outcome (dependent variable), and keeps everything else constant (controlled variables). A control group has no treatment for comparison.
Data & Statistics
Mean (average), median (middle), mode (most common), standard deviation (spread). Scientists use these to determine whether results are significant or could be due to random chance (p-value < 0.05).
STEM Careers in Oklahoma
Oklahoma's economy is built on energy (petroleum engineers, geologists), agriculture (soil scientists, biologists), aerospace (NASA at Johnson, Air Force bases), and a growing tech sector. The median STEM salary in OK is $65,000+.
Your Research Journey
Science fair → STEM summer programs → AP/Dual Enrollment courses → University research labs (OU, OSU, Oral Roberts, Langston) → Graduate school or industry. Every Nobel Prize winner started with curiosity.
🔬 Virtual Lab: Research Question Designer
Build a valid research question by selecting topic, independent variable, and dependent variable. The lab generates your hypothesis and experimental outline.
✅ Check Your Understanding
1. What is the variable you intentionally change in an experiment?
2. What does peer review accomplish in science?
3. A p-value less than 0.05 in a study means:
