Welcome to Mrs.G's Web Site
Have fun learning science with a crazy teacher!
Reminder: other than the recommendation section,
STATEMENT OF THE PROBLEM
is a statement of what you hope to discover. What you have learned through
your research, and what problem you hope to solve.
is a statement of why you hope to discover the answer to your project's
question. Why is your discovery important?
A HYPOTHESIS is an EDUCATED GUESS about the outcome (results) of your
experiment. It is what you think might happen when you do your experiments...
what effects or results do YOU expect, based upon your BACKGROUND RESEARCH?
are the step by step recipe of how you will perform you experiment!
Be very complete. Could someone in another state perform you lab EXACTLY
as you did?
in outline form, not sentence form :
as specific as possible-- list everything you will change including
amounts, intervals, conditions,-- everything!)
In a numbered list, describe every item you will need to run this experiment. Include quantities, sizes, brands, colors, shapes, tools, volumes. Use metrics when possible. Use diagrams or sketches if needed.
KEEP A SCIENTIFIC LOG OF EVERYTHING THAT HAPPENS WITH YOUR EXPERIMENT!! This will be a composition book that will be placed in the back pocket of your science notebook.
log is like a diary- it is your day-to-day notes on how things are
going. It includes your observations, measurements, ideas learned
from books, how your procedures change, ideas you've learned from
talking to various people, tables and charts, sketches, and photographs.
DATE every entry in your log. EXAMPLE: 10/01: Received permission
from teacher to test all 8th grade students in her science classes...
she has 80 girls and 75 boys... how convenient! Also, I was able
to obtain the 150 50 mI beakers needed for the experiment..." This
will be placed in the appendix sections of your science fair notebook. Here's
Day 4, October 18, 2007
Plant Growth (cm)
Fifth, obtain permission
o This is VERY important
o If you are doing an expt. involving people (surveys)
o Create a permission slip form where you get their name, age, signature, and parent signatures to
participate in your survey/experiment
o Keep these - you will need them in your SF notebook appendix
o If you are doing an expt involving bacteria:
o Get a Hazardous Materials form and complete it as much as possible prior to work
Ok, are you finally ready?
o You have all of your materials
o You've received permission from all necessary participants/adults
o Your procedures have been approved
o You made data tables and put them in your notebook
o Sounds good to me! Begin the experiment!
Quantitative Data -record this in your previously-made data tables
o be exact!!!
o record to the nearest hundredth if possible (5.87 mL)
o use units
o always double-check your measurements, and what you've written down
Qualitative Data - record EVERYTHING! - taking pictures/videos makes this part extra good
o Also, make sure to record the conditions of your experiment and changes that you are making.
o Did you skip a step? Add a step?
o What is the weather like? Does this matter or could it affect your results?
o You need to record EVERYTHING! Be honest, you can explain mistakes or negative results later.
o Tip: It is always better to write as much as you possibly can, than to be short of info later.
o All of this info will end up in your final notebook under the observations and results sections make it neat and professional.
o In the results sections, you will include all of your observations, data, tables, charts, pictures, diagrams, sketches, statistical analysis, and general descriptions.
o This part will be at least 2 pages long, without even adding your pics and diagrams.
In this section of your Science Project Notebook, you will write out what happened during your experiment. Tables, graphs, charts, photographs, sketches, statistical analyses, and general descriptions of observations are included. This written description of the outcome to your experiments will require at least two pages. DO NOT MAKE CONCLUSIONS! Simply present the results that occured.
ALL MEASUREMENT DATA in
Never lose this information - it must be included in the final paper! Include EVERYTHING in your log -- all data, even if the experiment does not come out the way you expected! Be honest please -- even negative results are useful! Make accurate measurements! Take photos as you perform your experiment!
Results Overview -
In this section of your Science Project Notebook, you will show and write out what happened during your experiment. Tables, graphs, charts, photographs, sketches, statistical analyses, and general descriptions of observations are included. Do not include the actual math, that part comes in your log or rough draft work. This written description of the outcome to your experiments will require at least two pages.
Results - The Goal
o The goal of the results section is to show AND explain what happened during the experiment.
o Realize, as of now, you are the only one who knows what happened, what went right and what
o In this section - you explain EVERYTHING and SHOW it through graphs/tables/pictures as
o HOWEVER, do not make conclusions!!!
Results Part A: Data Table
o Record your information from your experiment onto a data table (s).
o Make it a final draft, typed on computer - I find making a Table on Word is pretty easy.
o Be sure to include all variables, trials and controls.
o Don't forget to include the units.
o Round every number to the same decimal spot, in other words - everything should be at the
hundredth or thousandths place. If you couldn't get that specific - round to the nearest
o Calculate and include averages.
o LABEL EVERYTHING!!! Titles, tables, columns, rows, everything!
Results Part B: Graphs
o Create graphs using results from the data table.
o Typically, you will be graphing measured variable vs. changed variable.
o With surveys, you might use bar graphs with percentages.
o Use Excel to produce your graphs - no hand drawn graph paper graphs will be accepted.
o Choose the right intervals for your graph. If you're measuring to the nearest hundredth,
don't make a graph with intervals of 50.
o LABEL EVERYTHING!!! Titles, tables, columns, rows, axis's, everything!
o Using the appropriate graph for your particular data is very important.
If the graph doesn't show you anything, change graph type.
Results Part C: Sketches, Photographs
o Include all photographs taken throughout experiment.
o Assign a number to each one - figure 1, figure 2
o Include a brief caption or title for each one
o Sketches may also be included - but must be professional looking.
Results Part D: Summarizing the Experiment
o After you have produced your data, tables and graphs, you type a 100-500 words,
analysis of the data.
o Your results section should describe WHAT happened when you tested each of your
o You need to write down all of your experimental observations in detail.
o Describe which variable did the "best" and which did the "worst".
o You should refer to your hypothesis and describe how your ending results differed from
your hypothesized predictions.
o Describe any problems or changes you made in your experimental procedures.
o Did everything work the way you thought it should?
o Did you have to start over or use different materials?
o Describe your various trials; how were they the same? How were they different?
o Did any unplanned variables affect your results?
this section, you will draw your conclusions based upon the experimental
collected data in your log and analyzes the results. In
this section, you will draw conclusions based upon the experimental
collected data in your log and after analyzing the results.
o Conclusions are usually at least two double-spaced pages in the Science Fair Notebook - its
basically an essay.
o Start with a powerful opener and continue it with topic sentences until the end.
o Use scientific writing and no Is and yous.
o First, discuss DATA!
o Be positive, look at any possible patterns, explanations of data (own theories as to why it
turned out the way it did).
o Restate the original hypothesis and continue with what conclusions were discovered through
o Here comes the science - what did you learn scientifically?
o How can you explain your results, using science?
o At the end of the conclusion, refer back to the purpose and statement of problem of your
o Did you answer the big question?
o End with the bigger picture, what use the experiment might be to humankind.
analyze strengths and weaknesses of the experimental design,
gives possible explanations as to why the results occurred, and suggests
future improvements on the experimental design. This section should
be 1/2 -1 page in writing.
o Look at what went wrong and explain why.
o Make suggestions or explanations for inaccurate or unexpected results.
o Suggest future improvement on the design of your experiment, what should you have done.
o How can you make this experiment better?
