Are Childproof Containers Really Childproof?

Science Fair Project Idea

Scientific Method

Have you ever woken up in the middle of the night just not feeling well? Maybe your mom or dad gave you some medicine and you felt better after taking it. Medicine is a great tool in the fight against an illness, but medicine can be a poison if too much is taken. Similarly, household products can clean your home and make it smell great, but if eaten, can be poisonous. That is why most medicines and household products are stored in childproof containers. But are childproof containers really… Read more

Bacterial Resistant Materials and the Best Disinfectant

Science Fair Project Idea

Scientific Method

If you'd rate yourself high on the bacteriophobia scale, just keep on scrolling down to the next project. Bacteria are all around us, and normally our body's defenses keep us blissfully unaware of them. If you don't mind finding out where they're lurking in your house, then you might find this project interesting. Read more

Sound Localization

Science Fair Project Idea

Scientific Method

How accurately can people identify the location of a sound source when blindfolded? Imagine the hemisphere of space that extends above your shoulders at arm's length. Divide that hemisphere up into regular sectors and test the ability of blindfolded test subjects to point to a remembered sound source. For example, you could use the beep from a timer held at each test location, and then have the test subject point to where they think the timer was located. Record the magnitude and direction of… Read more

Candy Confusion: Can Small Children Mistake Medicine for Candy?

Science Fair Project Idea

Scientific Method

Many medicines come in bottles with special child-proof caps so that small children can't accidentally open the bottle and eat the pills. To a small child who can't read the label, the pills might look just like candy. What cues do we use to tell the difference between medicine and candy? At what age can we tell them apart? This project can show you how to find out. Read more

Growth and Age

Science Fair Project Idea

Scientific Method

One thing that all living things have in common is that they grow through cell division. How is this growth regulated? Sometimes growth occurs when it is not supposed to, leading to cancer. Scientists are trying to discover how growth is regulated, hoping to find potential cures for cancer. One idea is that cells keep track of growth using special regions of the chromosome called "telomeres" that count how many divisions a cell has made. If this is true, then growth, cell division and age are… Read more

What Bone Do Children Break Most Often, and What Is the Main Cause?

Science Fair Project Idea

Scientific Method

Here's a project that will give you insight into accidents, and maybe help you prevent them. The original project used a survey method to gather data, which you could also do. Another approach for data collection that you might try would be to use published articles from the pediatric medical literature. Finding a pediatrician or pediatric orthopedist who is willing to be your mentor for this project would be helpful. (Idea from Caito, 2003) Read more
