The middle school years are
a great time to get excited about science. Now
you can start doing in-depth thinking on your own as you develop a science
project about a topic that interests you.
Science Fair Projects for Middle School
All projects should use experimentation to answer a testable
question. In other words, use the
But don't worry—it's not as hard as it sounds!

the germination of monocot
seeds and dicot
seeds. Experiment with
different factors, like sunlight, fertilizer or water, that affect germination (seed
with how the pH of
soil affects plant growth. (Use a
soil analyzer.) Develop an experiment that tests the importance of CO2
to plant health.
Do plants grow differently under different wavelengths of light (like
ultraviolet and fluorescent)?
Design an experiment to discover the effects of abnormal radiation on plant
growth, using irradiated
seeds that are treated at different radiation levels.
microscope to study protozoa. (Find them in a local pond, or
grow them yourself. To experiment with
specific species, purchase a
live culture.) How do heat, light, and water pH affect them? You
could also do a pond water study to determine the various effects of
pollutants on pond life.
with the use of antibiotics
and common household
cleaners to fight bacteria growth. (To grow your own bacteria samples, use
agar & petri dishes. For a
sample step-by-step procedure and more project ideas, check out our
bacteria science project
Do bees recognize patterns?
Can this help them find their food sources?
- How do ants lead each other to a
food source using scent (pheremones)? And what effect does temperature have on ant movement?
Experiment with Glo Germ gel to
develop methods to stop the spread of germs.

Experiment with the effects of erosion (by
wind, water, ice, or gravity) on different rock or soil types. Does
vegetation in the soil slow erosion? See our
rock experiments for more
test to discover if local minerals contain carbonate compounds, and
consider how this might relate to the surrounding plant and animal life.
out how temperature,
wind, or humidity affects the
rate of evaporation.
Does that have any impact on precipitation? (Compare hot and humid to hot and
windy or hot and cloudy environments.)
holes are formed when the rock below the soil is dissolved by ground
water. What kind of rock would
present the most risk of a sink hole? How might acid rain or chemical waste
Experiment with a black light to test for
fluorescent minerals. Do minerals fluoresce differently under longwave and
shortwave ultraviolet light?

earth science projects page.
to analyze the light spectra produced by burning different elements. Do you expect compounds that contain
some of the same elements to have similar spectra?
your own light
bulb, and then experiment with what materials make the longest-lasting
or brightest filament.
kind of substance (metal, ceramic) conducts heat the best? Do a thermal
conductivity study to discover which substance works best for a pot
handle and which works best for a teapot.
out how increased mass affects velocity and acceleration by doing a
project with dynamic
carts. You can also experiment
with the resulting velocities after a collision between a moving object
and unmoving one, or between two objects moving in opposite
Build a wind turbine and
experiment to find out how blade design, wind speed, and other factors
affect power production.
with the best way to build a solar
oven to cook your own food.
Build magnetic tracks to levitate different objects, using a a kit like
Magnetic Levitation. What effects do
more powerful magnets have? Test neodymium
and ceramic magnets.
Experiment with the best design and method of propulsion for a
rocket car, mouse trap car, and solar car.
Make your own electromagnets
and find out what kind of battery, solenoid, etc. can produce the strongest
Find more ideas on the
drinkable water from salt water using the sun. What materials can you use to speed up
the rate of evaporation?
your own ink
using different substances and compare how each withstands the effects of
heat, light, or moisture. For
example, does one type fade faster than another when they are heated or
when exposed to strong light? What chemical reactions might cause this?
pennies to copper-plate
an iron nail. See if pennies minted
before 1982 (when they were 95% copper) make a thicker coating than newer
pennies do (they only have 2.5% copper). How does the number of pennies you use
affect the time it takes to plate the nail?
membrane to experiment with osmosis. What kinds of substances pass through the membrane, and what
substances don't? What is a common
property that prevents substances from passing through the membrane?
retains heat longer, salt water or fresh water? Design an experiment to find out.
Experiment with the
chemistry of food, including testing for vitamin C, glucose, starch,
protein, and lipids (fats). Does cooking, canning or freezing change the
nutritional value of certain foods?
How do crystals
form? Does the rate at which they form affect their size and shape? Can you
make crystals with household chemicals?
