Science Fair Project Ideas
Thick Liquids
Design an experiment to find out how the thickness (viscosity) of a liquid
affects how objects sink into it. You can drop fishing weights into equal
amounts of liquids. Use a stopwatch to measure the time for the fishing
weights to reach the bottom of each container.
Conducting Heat
Design an experiment to find out how long it takes heat to travel through a
solid. You can use a metal skewer and attach small blobs of wax to it. With
an adult’s help and using a pot holder, you can hold the tip end near a heat
source. Then, use a stopwatch to measure the time it takes for each piece of
wax to melt and fall off.
Megaphone Ears?“
After you have studied sound, measure how much further you are able to
hear when your “ears” are enlarged. Using paper cup ears, you can measure
the distance at which you can hear a ticking clock. Then design and test the
best “ear” to capture sound.
Plan and conduct an experiment to find out how well people can predict
colors. You can use food coloring to tint water in clear bottles or glasses.
Several objects can be selected, each a different color. Find out what color
the object appears when seen through the tinted water, when lighted with a
beam shone through the Water, and when seen in white light. Ask others to
look at the object through the tinted water and predict what color it will be
in white light.
Design an experiment to find the best treatment to reduce the cling caused
by static electricity. You can begin by rubbing air-filled balloons with wool
to generate static electricity. The amount of static electricity can be inferred
by observing how much confetti a balloon will pick up. Rub or coat the
balloon with various liquids to see how the liquids affect static cling.
Design an experiment to measure the speed of an animal such as an insect,
a bird, or a family pet. For example, you might measure the time it takes for
a beetle to crawl through a plastic tube. Be sure that you treat all animals
humanely.
Read a book such as How D0 You Lift a Lz'011?by Robert E. Wells. You can
design an experiment to find the most efficient Way to pull a heavy object,
such as a panda, on a pallet. A spring scale can be used to measure force.
Provide graphs that illustrate your findings. If you used a book, remember
to credit that book
