Experiment Builder
Build Your Scientific Experiment
This tool will guide you through designing a complete scientific experiment. Use the question framework on the left to shape your research question, then explore what kinds of experiments are possible on the right.
How it works:
- Left panel: Frame your scientific question, and open the PDSA Investigation Assistant for guidance and feedback
- Right panel: Design your experiment step-by-step
- Connection: Your question and experiment design inform each other
Select Object & Property/Process
Choose an object, substance or material. Then, select the physical property or biological/chemical process you want to investigate.
Select Measuring Tools
Choose the tools you will use to measure the property or process selected in Step 1. You can select multiple tools if needed.

Number of Trials / Repeats
How many times will you repeat the measurement under the same conditions?
- Calculate a more reliable average
- Spot outliers or errors
- Assess how consistent your results are
- Increase confidence in your conclusions

Data Processing & Graphing Guide:
Working with Your Data:
Step 1: Calculate Averages
For repeated trials, calculate the average (mean) of your measurements. This gives you a more reliable result than any single trial.
Step 2: Choose the Right Graph Type:
- Column/Bar Charts: Use for comparing categories or subjective ratings (e.g., comparing juiciness of different oranges, rating scales 1-5)
- Pie Charts: Use for showing parts of a whole with categorical data (e.g., percentage of students who prefer each condition)
- Line Graphs: Use when showing how something changes over time or with continuous variables (e.g., temperature vs. dissolving rate)
- Scatter Plots: Use to show relationships between two numerical variables (e.g., heart rate vs. exercise duration)
Step 3: Graph Your Results
Plot your averages or percentages rather than raw individual measurements. Include error bars if you know how - they show the range of your data.
๐ก Tip: Your graph should clearly show whether your hypothesis was supported or not. A good graph tells the story of your results!
