METEOROLOGY
Sky
Color- account for differences in color at different times
Wind
and Clouds- what are the common wind patterns in your area and
why? Is cloud formation related to height, weather systems and
temperature? Study and record how clouds relate to weather
patterns.
Wind-does
wind travel at same speeds and in same directions at different
heights?
Evaporation-
which effects the rate of evaporation most- temperature,
humidity, wind speed or other factors?
Heat
Retention- does fresh water hold heat longer than salt water?
How does water compare to land and what effect does this have on
the weather? What factors affect the cooling of land?
Sunlight-
how do different surfaces affect the amount of sunlight
reflected and absorbed? Design a method of measuring how much
sunshine is available each day.
Weather
records- Design and build an automatic recording weather device.
Test it over a period of time.
CHEMISTRY
Chemical
reactions that produce energy or that require energy
Testing
of consumer products- glues, stain removers, antiseptics,
mouthwash, detergents, paper towels
Compare
the PH levels in mouths of various animals and humans at
different times in the day
Compare
the surface tension of various liquids
Dealing
with chemical spills from industry
Effects
of salt and other contaminants on rate of rusting
Growing
crystals- factors that affect the rate and the size
Can
you obtain water from ink, vinegar, milk?
Analyze
soil samples for their components, ability to hold moisture,
fertility and PH
Does
the amount of particle pollution vary with distance from a road,
with location, with height. Determine types of particles found
in pollution fallout
How
do acids react with different metals under varying conditions
Identify
different metals by the color of flame when they burn
Can
you devise an experiment that will list metals in order of their
activity, from the most potassium to the least active ore gold
Electroplating-
the principles, how different metals can be used and the
practical applications
How
to make PH indicator using cabbage?
How
Yogurt is made? Is it a chemical or biochemical reaction?
Effects
of temperature on viscosity of oil
Making
salt water potable, removal of pollutants
BOTANY / BIOLOGY
Photosynthesis
- factors affecting the rate of photosynthesis (temperature,
light intensity, water, carbon dioxide)
- part of light spectrum used in photosynthesis
Family
studies on inheritance
Genetic
Studies - connections between hair and eye color
Determine
the effects of various nutrients on plant growth
How
does the amount of water affect plant growth?
How
does the hours of sunlight affect the plant growth?
How
does the strength of weed killer affect the plant growth?
How
does PH level affect the plant growth?
Can
plants live without Carbon Dioxide?
Roots
- how do different types of soils affect the ability of roots to
anchor plants?
What
conditions are favorable for: -fungus growth- E.G. yeast, mold,
mildew diseases ?
What
conditions are favorable for: bacteria growth or control?
