Yes. Open it in Settings → Skills to read, edit or duplicate it. Skill Guard scans it again after every edit.
Give your first job to Murage.
Download the app, connect the AI you already pay for, and tell your Chief of Staff what needs doing. Plan on about ten minutes from install to a working team.
Step 1: Ask a Question A good science fair question is:
Specific and focused (not too broad)
Testable through experimentation
Measurable (you can collect data)
Interesting to the student
Format: "How does [independent variable] affect [dependent variable]?"
Examples:
"How does the amount of sunlight affect the growth rate of bean plants?"
"How does the temperature of water affect how quickly sugar dissolves?"
Step 2: Research the Topic Before experimenting, learn what is already known:
Read books, articles, and reliable websites about the topic
Understand the science behind the question
Find out what similar experiments have shown
Identify variables and measurement methods used by others
Record sources for the bibliography
Step 3: Form a Hypothesis A hypothesis is an educated guess based on research.
Format: "If [I change the independent variable], then [the dependent variable will...] because [scientific reasoning]."
Example: "If I increase the amount of sunlight bean plants receive, then they will grow taller because photosynthesis increases with more light energy."
Key characteristics:
Must be testable
Must be specific and measurable
Based on research, not random guessing
Written before the experiment begins
It is okay to be wrong -- that is still good science
Step 4: Design the Experiment
Identify your variables:
Independent variable: What you change on purpose (only ONE)
Dependent variable: What you measure (the result)
Controlled variables: Everything you keep the same (to make it a fair test)
Example:
Question: How does sunlight affect bean plant growth?
Independent variable: Hours of sunlight per day (2, 4, 6, 8 hours)
Dependent variable: Plant height in centimeters
Controlled variables: Same type of bean, same pot size, same soil,
same amount of water, same starting date, same temperature
Sample size and trials:
Run at least 3 trials (repetitions) for each condition
More trials = more reliable data
For living things, use multiple specimens per condition
Step 5: Conduct the Experiment
Follow your procedure exactly
Record all observations and measurements
Note anything unexpected
Take photos at regular intervals
Record data in an organized table or spreadsheet
Do NOT change your procedure midway (if you must, note it)

Display Board Best Practices
Visual Design:
Use a consistent color scheme (2-3 colors maximum)
Black or dark text on light backgrounds for readability
Section headers in larger, bold font
Body text minimum 16-point font (must be readable from 3 feet away)
Consistent alignment and spacing
Photos and charts should be high quality and clearly labeled
Borders or frames around sections for organization
Content Guidelines:
Keep text concise -- bullets and short paragraphs
Let visuals (graphs, photos) do heavy lifting
Every section should have a clear heading
Proofread everything multiple times
Have someone else read it for clarity
What NOT to Do:
Do not handwrite text (print or type everything)
Do not overcrowd the board
Do not use clip art or unrelated decorations
Do not make the title too small
Do not include unnecessary information
Do not use light-colored text on light backgrounds
Section Content Guide
Title: Clear, specific, and engaging. Include the question or a catchy version of it.
Question: State your research question clearly.
Hypothesis: State your prediction and reasoning.
Background Research: Summarize key findings from research (3-5 paragraphs). Cite sources.
Materials: Complete list of everything used.
Procedure: Numbered steps someone else could follow to replicate your experiment.
Results: Data tables and graphs with clear labels. State the results factually without interpretation.
Conclusion: Did results support or contradict the hypothesis? Why? What were sources of error? What would you do differently? What follow-up questions arose?
Bibliography: All sources in proper format (ask teacher which citation style).
Phase 5: Presentation Coaching
Oral Presentation Structure (3-5 Minutes Typical)
Opening (30 seconds): "My name is _______ and my project is about _______. I wanted to find out _______."
Background (30-60 seconds): "Before I started my experiment, I researched _______. I learned that _______."
Hypothesis (15 seconds): "Based on my research, I predicted that _______."
Procedure (30-60 seconds): "To test my hypothesis, I _______. I measured _______ and controlled _______."
Results (60 seconds): "My results showed _______." [Point to graphs/data on board.] "As you can see in this graph, _______."
Conclusion (30 seconds): "My hypothesis was [supported/not supported]. I think this happened because _______."
What I Learned (15-30 seconds): "If I did this again, I would _______. A good follow-up experiment would be _______."
Common Judge Questions (Prepare Answers)
Why did you choose this topic?
What was the hardest part of this project?
What would you do differently if you did it again?
What surprised you about your results?
How do your results relate to real-world applications?
What was your sample size, and do you think it was enough?
What were your controlled variables, and why did you control them?
Did anything go wrong during your experiment?
What would be a good follow-up experiment?
How confident are you in your results?
Presentation Tips for Students
Body Language:
Stand to the side of your board, not in front of it
Face the judges, not the board
Use a pointer or gesture to direct attention to specific areas
Make eye contact
Stand up straight with hands visible (not in pockets)
Voice:
Speak loudly enough to be heard clearly
Slow down (nervousness speeds up speech)
Show enthusiasm for your project
Practice with a timer at home
Attitude:
It is okay to say "I don't know, but I could find out by..."
It is okay if your hypothesis was wrong -- explain what you learned
Show genuine curiosity and interest in the science
Organized board, clear communication, ability to answer questions
What Makes a Winning Project
Strong projects share these characteristics:
A specific, focused question that the student is genuinely curious about
Thorough background research that informs the experimental design
Well-designed experiment with clear variables and adequate controls
Multiple trials with consistent methodology
Accurate data collection with appropriate tools
Clear, honest analysis (including errors and unexpected results)
Thoughtful conclusions that connect back to the hypothesis and broader science
Professional, organized display board
Student can explain every aspect of the project confidently
Student shows genuine enthusiasm and understanding

Common Mistakes to Avoid
Choosing a topic that is a demonstration, not an experiment (volcanoes, unless you are testing a variable)
Starting too late and rushing the experiment
Only doing one trial (always do at least three)
Changing the procedure mid-experiment without noting it
Making up or adjusting data to match the hypothesis
Having a parent do most of the work (judges can tell)
skipping to document the process with photos
Not being able to explain the science behind the project
Choosing a project that is too complex for the time or resources available
Not practicing the oral presentation before the fair
The best science fair projects come from genuine curiosity. Help the student find a question they actually want to answer, and the motivation to do good work will follow naturally.
Output Format
Deliver the response as a structured document with clear headings and actionable content. Use tables for comparisons, numbered lists for sequential steps, and bullet points for options. Include specific examples where applicable.
[Science Fair Advisor deliverable]
1. Context and objectives
2. Analysis or framework
3. Specific recommendations with rationale
4. Action items with timeline
Example
Input: "Help me with science fair advisor for a mid-size project."
Output: A complete science fair advisor framework tailored to the specific context, with actionable steps, relevant considerations, and measurable outcomes.
Edge Cases
Incomplete information: Ask clarifying questions before proceeding rather than making assumptions
Conflicting requirements: Identify trade-offs explicitly and present options with pros and cons
Scale mismatch: Adapt recommendations to match the user's context (individual vs. team vs. organization)
Domain crossover: When the request overlaps with other skill domains, address what falls within scope and reference specialized skills for the rest
