Overview of Day. Orientation until 9:30 a.m. Judging: 10-1:30 p.m. Lunch: 11:00 –1:00 in this room Closing Ceremony: after completion of judging Post-Fair Awards ceremony. Philosophy of Fair. Community event Intended as fun day of science
K-2, 3-5, 6-8
What did YOU change
Meets Ex.= fertilizer
Better = fertilizer delivery system
fertilizer chemical composition
What did YOU measure = must be #s
Meets Ex. = growth
Better = height or # leaves or mass
- may have to develop a scale to compare to
I think IF………THEN…….because……….
Not deep research – what do you think
will happen when you change your IV??
Meets Ex. = I think if I use liquid fertilizer
then my grass will grow better because
it will spread out quicker to the seeds.
Better = I think if I use liquid fertilizer
then my grass will grow taller because
the liquid will diffuse throughout the soil
and be taken into the roots easier than
having to dissolve the solid fertilizers.
BE SPECIFIC – include amounts!!
There’s nothing worse than getting to the point of adding the chocolate
chips to your cookie dough and not having enough!!
Meets Ex. = 5 kinds of fertilizers
Better = EXACT types, sizes
exact differences – liquid/solid
nitrates vs phosphates etc
Control: what you compare your results to
how did you know what happened??
understanding of controls should improve w/ age
Meets Ex. = just water
Better = the height of seedlings that received
just water instead of added fertilizers
Constants: what you keep the SAME
what makes a fair trial
Meets Ex. = type of seeds, environment
Better = type and number of seeds in same
amount of soil – time of day delivery
of water + fertilizer – time span experiment
Procedure: what you did!!!
EXACTLY – should be able to be re-done
list in numbered form to make easy to follow
If testing change need to find the START
and then find the CHANGE
ex height before fertilizer or pulse before exercise
Must use METRIC units
Must have trials or repeats + finding averages
Data Table: ALL of your results
raw data – properly titled and UNITS labeled
The effect of different fertilizer delivery systems
of the height of grass grown in 2 weeks
The effect of different exercisers on the
change in pulse rate
Graph: show analysis of results
– properly titled and UNITS labeled
Usually X axis = IV Y axis = DV
Data Table and Graph need to have enough info to STAND ALONE and show/explain what your project did and found Must have both a table and graph labeled and with measurement units
So Conclusion = WHAT you found out and how that compares to hypothesis
Hypothesis can be wrong
– you don’t necessarily know WHY
– can suggest ideas for further study
