01 // Question
What are you trying to figure out?
Begin with an observation or phenomenon. Then turn it into a focused question that can be investigated with evidence.
Question + Method
Describe the phenomenon before trying to explain it.
Strong questions connect something you can change or compare to something you can measure.
Think testable. Could you collect measurable evidence that would help answer this question?
02 // Hypothesis
Make a testable prediction.
Identify what you will change, what you will measure, and why you expect the relationship.
Variables + Prediction
What will you deliberately change or compare?
What outcome will you measure?
Use scientific knowledge or a scientific mechanism. Avoid simply restating the prediction.
Hypothesis scaffold
If the independent variable changes, then the dependent variable will change as predicted, because scientific reasoning.

03 // Design
Design a fair test.
Plan how you will collect evidence that isolates the relationship you are testing.
Experimental Design
Fair-test check
Use these as thinking prompts. They are not automatic proof that the design is valid.
04 // Data
Record what happened.
Enter evidence before deciding what it means. Describe patterns using actual measurements.
Data + Representation
Prototype data table. This version provides a flexible four-condition table. A later teacher builder could generate tables automatically from the experiment design.

Trial 2
Trial 3
Mean / summary
Use numbers, measurements, or direct observations. Add up to four pieces to your evidence tray.
05 // Explain
What does the evidence mean?
Construct a claim, support it with selected evidence, and connect the evidence to scientific reasoning.
Scientific Argumentation
Answer the investigation question based on the evidence you collected.
Your evidence appears here so you can decide what actually supports your claim.
Explain why the evidence supports your claim using scientific ideas, models, or mechanisms.
06 // Revise
How has your thinking changed?
Science advances by revising explanations in response to evidence. Compare your original prediction with what you now understand.
Revision + Reflection
Original hypothesis
Your original hypothesis will appear here.

Dr. Teach Tech Teacher GuideScience Investigation Builder
For classroom implementation
Use the tool to structure thinking, not replace it.
The Science Investigation Builder is designed to sit beside a lab, field investigation, demonstration, or student-designed inquiry. Students move through Question → Hypothesis → Design → Data → Explain → Revise while the teacher decides how much of the investigation is already provided.
Quick start for teachers
1. Decide what students own
Choose whether you will provide the phenomenon, research question, variables, procedure, or data. The tool works best when students are responsible for at least one meaningful scientific decision.
2. Stop at natural checkpoints
Question/Hypothesis works well before the lab. Design can be reviewed before materials are distributed. Data/Explain/Revise can happen after evidence is collected.
3. Export into the lab
At the end, students download their summary and add it to a lab report, science notebook, LMS submission, or portfolio. The app is a reasoning workspace rather than the final lab itself.
Recommended teacher move: Project the app once and model a deliberately weak hypothesis or procedure. Ask students what needs revision before showing how the tool prompts them to improve it.
Early in a course or when the lab technique itself is new.
Semi-Guided Inquiry
Phenomenon, material limits, safety constraints
Question, variables, design decisions, analysis
Most college-prep labs and AP skill practice.
Open Inquiry
Broad phenomenon or problem
Question through revision
Culminating investigations, science fair preparation, AP inquiry, or capstones.
Using it across high school science
Each sample below preloads a complete investigation so teachers can preview the workflow. The same course can use many different investigations. Samples are demonstrations, not prescribed labs.
BIOLOGY
Biology
Emphasize: controls, biological variation, sample size, mechanism, and evidence-based explanations.
Emphasize: field sampling, natural variability, correlation versus causation, human impacts, and evidence-supported solutions.
Water quality and nutrient levels
Soil, runoff, or biodiversity
Microclimate and land cover
EARTH & SPACE
Earth & Space Science
Emphasize: models, systems, rates of change, indirect evidence, and interpreting patterns across time or space.
Erosion and slope
Albedo and surface heating
Soil permeability
PHYSICAL SCIENCE
Physical Science
Emphasize: clear IV/DV relationships, measurement units, fair tests, simple graphs, and connecting observations to models.
Mass and motion
Heat transfer
Dissolving or density
ANATOMY
Anatomy & Physiology
Emphasize: operational definitions, biological variation, ethical data collection, baseline comparisons, and homeostasis.
Exercise and recovery rate
Reaction time investigations
Respiration rate before and after activity
AP science implementation
For AP courses, use the same workflow but reduce sentence scaffolds over time. Ask students to justify methodological choices, quantify evidence, create or interpret representations, and explain limitations instead of merely naming them.
AP BIOLOGY
AP Biology
Strong fit for experimental questions, controls, data representation, statistical reasoning, and argumentation. Require students to connect evidence to biological processes.
AP CHEMISTRY
AP Chemistry
Use for question/method decisions, quantitative data, particle-level explanations, sources of experimental error, and method improvements.
AP PHYSICS
AP Physics 1 / 2 / C
Require prediction sketches, quantitative graphs, units, slopes or model relationships, repeated measurements, and explicit uncertainty reasoning.
AP ENVIRONMENTAL
AP Environmental Science
Use with lab and field work to practice data interpretation, environmental relationships, sampling limits, and evidence-based solutions.
AP progression suggestion: Early year, leave the prompts visible. Midyear, require more independent language and stronger quantitative evidence. Before the exam, use the tool as a planning frame, then have students answer comparable prompts without the scaffold.
Multi-day investigations
Day 1: Before the lab
Students sign in, select their course, complete Question and Hypothesis, then begin Design. Teacher conferences can happen before students touch materials.
Day 2: Collect evidence
Students reopen work using the same email on the same browser, or load their backup. They complete or revise Design and enter data.
Day 3+: Explain and revise
Students select strongest evidence, construct a claim and reasoning, identify limitations, revise their hypothesis, then download the summary for the lab report.
Shared-device recommendation: Have students use Save & exit when finished. Browser storage is convenient, but a connected or downloaded backup is the safer choice for investigations lasting several days or moving between devices.
