Science Project Ideas
Return to www.101science.com home page.      

One of the hardest parts of starting a science project is deciding what the project will be.  We present to you below many ideas to
choose from.

Which characteristic is most influential in attracting bees to a flower: fragrance, color, or flavor?

Make a sundial.

The effects of gender identity on short term memory.  Do boys or girls have better short term memory?

Do all plants transpire at the same rate under different sources of light?  Use 2 liter plastic soda bottles with their bottom cut out placed over a plant to collect the moisture given off by the plant.  Carefully remove the bottle and scrape the water out into a measuring cup.   Try this with different plants over same time period under different lighting conditions.

Determine the effect of light on plant growth and development.

Can plant cloning be used effectively to produce growers?  (Produce: meaning fruits and vegetables.)

Determine the vitamin C content of fruit juices.

How effective is beta carotene in fighting cancer in plants?

Determine the effects of UV radiation on growth and development of plants or microorganisms.

Determine the effect of electromagnetic fields on eremosphaera algae cells.

Design a solar energy device.

Determine the factors affecting the amount of aluminum in foods.

What is the most effective substance to melt ice?  Try salt (sodium chloride), calcium chloride, cat litter, sand, rubbing alcohol, and rock salt.

What pH level is most conductive to corrosion in iron and copper?

How effective is lobster shell chitin in filtering wastewater metallic ions?

How does salt water mix in an estuary?

Prepare, analyze, and demonstrate the Meissner effect.

Can the life span of a soap bubble be extended in different temperatures and atmospheric conditions?

What colored dyes are found in powdered drink mix and colored markers?

Can ocean waves be used to generate electricity?

Which form of insulation is most effective?

Alcohol as a fuel: recycling wastes into energy

Can CMOS logic, rather than a potentiometer, regulate voltage?

Build a robotic assisted plotter

Determine the effects of industrial pollutants in the environment of the convict cichlid fish]

What is the effect o0f #6 heating oil on the elodea densa in a aquatic environment?

Can limestone be used to protect pine trees from acid rain?

What section of a town has the most pollution in the form of airborne particles?

Determine the environmental effects of the biodegradability of plastic bags, paper bags, and newspaper.

How does acid rain affect the cell structure of spirogyra?

Common cold remedies: are they helpful?

What substance is most effective in cleaning teeth?

Are there really any differences among commercial hand lotions?

Detecting starch levels in apples:

Starch content is best tested with Lugol's solution which is a solution of potassium iodide. But, where are you going to get it? Carolina Science has it www.carolina.com but you may not want to wait for it to arrive. An alternative is to use ordinary tincture of iodine available at any local drug store. Not as good as Lugol's solution but it should work OK for you. It is the iodine used for cuts. How you might proceed is to crush small (say a pencil eraser size) equal amounts of each of your test apple samples, one sample in separate test tubes. Fill the test tubes with an equal amount of water (I'd suggest about 3/4 full. Stir vigorously. Then add one drop of Lugol's solution or tincture iodine (but not both). Observe the color intensity on a scale of 1 to 10, i.e. no color to dark blue/black. You could even make a test strip of these colors on a piece of paper using water color or crayons. Number each shade from colorless to black ; 1 through 10. Then compare each test tube against the chart and that will give you a relative quantitative number for each sample that you can chart. That should do it. If you have trouble seeing any difference in the colors you may have to repeat the experiment and adjust the number of drops and/or the size of apple slices to get a better middle range color. If you want it even simpler method you could just try touching a drop of the iodine to each apple slice and recording the color intensity but that would be less effective and harder to judge than the test tube solutions. If you don't have a source of test tubes handy you could use very small water classes or better yet clear plastic drinking cups you can throw away.  Just remember iodine is a poison and a stain and to throw away all test items and wash up your area with lots of soap water - never eat the apple slices after being contaminated with test solutions. In a real lab a scientist would use a photospectrometer to read the solution density percentage. That instrument gives a meter reading number that is not subjective and is quantitative. They also would include a "control" - in your case that would be a FRESH piece of apple for comparison. They would repeat the same experiment more than once to make sure the results come out about the same each time. That is done to give some sense that the experiment really shows a repeatable result.  Use the "Scientific Method" procedure in writing up your experiment.
