Assalamu alaikum.
Here are some ideas for the Science Fair!
Remember that Wednesday is the last day to choose your project idea!
Check out the web links at the bottom as well!
·
Try making colored
bubbles. Can you color them with food coloring? If so, what differences do you
notice between colored bubbles and regular bubbles?
·
Do you have birds in your
yard? People use scarecrows, plastic owls, and aluminum foil to try to scare
away birds. Do any of these actually work or are they a waste of money?
·
Figure out how much of
your family's trash you could recycle. Compare this against the total amount of
trash and draw conclusions about how much waste people throw away that could be
re-used.
·
Can you predict what things will glow under a black light?
·
Will chilling an onion before cutting it keep you from
crying?
·
What ratio of vinegar to baking soda
produces the best chemical volcano eruption?
·
What type of plastic wrap
best prevents evaporation?
·
What plastic wrap best
prevents oxidation?
·
Are night insects
attracted to lamps because of heat or light?
·
Can you make Jell-o using
fresh pineapples instead of canned pineapples?
·
Do white candles burn at
a different rate than colored candles?
·
Does the presence of
detergent in water affect plant growth?
·
Can a saturated solution
of sodium chloride still dissolve Epsom salts?
·
Does magnetism affect the
growth of plants?
·
Does the shape of an ice
cube affect how quickly it melts?
·
Do different brands of
popcorn leave different amounts of unpopped kernels?
·
How accurately do egg
producers measure eggs?
·
How do differences in
surfaces affect the adhesion of tape?
·
If you shake up different
kinds or brands of soft drinks (e.g., carbonated), will they all spew the same
amount?
·
Are all potato chips
equally greasy (you can crush them to get uniform samples and look at the
diameter of a grease spot on brown paper)? Is greasiness different if different
oils are used (e.g., peanut versus soybean)?
·
Do the same types of mold
grow on all types of bread?
·
Does light effect the
rate at which foods spoil?
·
Can you use a household
water filter to remove flavor or color from other liquids?
·
Does the power of a
microwave affect how well it makes popcorn?
·
Can you tell/taste the
difference between ground beef, chuck, and round after they have been cooked?
·
If you use invisible ink,
does a message appear equally well on all types of paper? Does it matter what
type of invisible ink you use?
·
Do different brands of
batteries (same size, new) last equally long? If a brand lasts longer than
others, does this change if you change the product (e.g., running a light as
opposed to running a digital camera)?
·
Do all brands of bubble
gum make the same size bubble?
·
Do all dishwashing
detergents produce the same amount of bubbles? Clean the same number of dishes?
·
Is the nutritional
content of different brands of a vegetable (e.g., canned peas) the same?
·
How permanent are
permanent markers? What solvents (e.g., water, alcohol, vinegar, detergent
solution) will remove the ink? Do different brands/types of markers produce the
same results?
·
Do consumers prefer bleached
paper products or natural-color paper products? Why?
·
Is laundry detergent as
effective if you use less than the recommended amount? More?
·
Do all hairsprays hold
equally well? Equally long? Does type of hair affect the results?
·
How do different factors
affect seed germination? Factors that you could test include the intensity,
duration, or type of light, the temperature, the amount of water, the
presence/absence of certain chemicals, or the presence/absence of soil. You can
look at the percentage of seeds that germinate or the rate at which seeds
germinate.
·
Is a seed affected by its
size? Do different size seeds have different germination rates or percentages?
Does seed size affect the growth rate or final size of a plant?
·
How does cold storage affect
the germination of seeds? Factors you can control include the type of seeds,
length of storage, temperature of storage, light and humidity.
·
How close does a plant
have to be to a pesticide for it to work? What factors influence the
effectiveness of a pesticide (rain? light? wind?)? How much can you dilute a
pesticide while retaining its effectiveness? How effective are natural pest
deterrents?
·
What is the effect of a
chemical on a plant? You can look at natural pollutants (e.g., motor oil,
runoff from a busy street) or unusual substances (e.g., orange juice, baking
soda). Factors that you can measure include rate of plant growth, leaf size,
life/death of the plant, color of plant, and ability to flower/bear fruit.
·
Do clear flavored drinks
and colored flavored drinks (same flavor) taste the same? Does it matter if you
can see the color?
·
What percent of an orange is water?
Get
an approximate mass percent by weighing an orange or other fruit, liquefying it
in a blender, and measuring the strained liquid. Note other liquids will also
be present, such as oils, though in small amounts. The mass of a ml of water is
1 g. Alternatively, you could bake the weighed orange until it is dried and
weigh it again.
·
Does the temperature of a soda affect how much it sprays?
You
can refrigerate a soda, warm one in a hot water bath, shake them up, measure
how much liquid is sprayed out. How do you explain the results?
·
Do all brands of soda spray the same amount when you shake them
up? Does it matter if it's diet or regular soda?
·
Do all brands of paper towels pick up the same amount of liquid?
Compare
single sheet of different brands. Soak a sheet until it is saturated, let the
excess liquid drip off, squeeze the liquid from the wet paper towel into a
measuring cup. Note you may need to use teaspoons to measure this liquid.
