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
Candy Corn Geodesic Dome
Blog Post
A classic science (and geometry) project takes on Halloween tones with candy corn-colored candies, a few ordinary toothpicks, and a bunch of triangles. We are big fans in my house of the geodesic dome. We initially tried a bigger-than-expected version made from straws a few years ago. We had a great time putting it together—but it would not fit through the front door! Making a small-scale geodesic dome from gummy candies is a much easier and… Read more
Candy Experiments: Doing Fun Science at Home during School Closures (Activity #23)
Blog Post
Follow along with a Science Buddies parent who is using family STEM activities to keep her kids learning at home during the COVID-19 school shutdown. New posts every Monday, Wednesday, and Friday. Today's adventure... experimenting with how candy coatings dissolve and the colors mix. An Experiment Full of Candy Makes the Whining Go Down Have you experienced a day during this quarantine when the whole family just seems to hit a wall? Everyone is… Read more

Do you filter your tap water before drinking? Maybe at home you have a water filter on your faucet, in the fridge, or use special pitchers that have a filter unit in them. You have probably heard in commercials that these filters are supposed to make your water cleaner and safer to drink. But have you ever wondered what, exactly, these filters are doing and if the water is really cleaner in the end? Find out about the cleaning power of water filters in this activity; but for results you can… Read more
Carbon Filters and Adsorbing Science
Blog Post
Explore the science behind a carbon filter with a fun hands-on family STEM activity. Now you see the color... and now you don't! Water filters that use activated carbon can help "clean" water. You might be able to see the difference the filter makes, but not always. In this week's family science activity, families can explore the way these filters work with a colorful hands-on project that makes stripping the color from a sports drink or colored soda… Read more
Catalytic RNA and Structure
Science Fair Project Idea
Scientific Method
Some sequences of RNA can catalyze biochemical reactions, much like protein enzymes. These catalytic RNA sequences are called ribozymes. The function of a ribozyme depends upon the primary sequence of the RNA which folds into a 3-D structure. How do different ribozyme sequences fold? You can search for ribozyme sequences using Entrez BLAST (NCBI, 2006). Then you can use a program like MFOLD (http://bioweb.pasteur.fr/seqanal/interfaces/mfold-simple.html) to submit your sequence for an… Read more
Catch the Wave!
Science Fair Project Idea
Scientific Method
There is a lot of energy that can be harvested from moving water. Energy can be extracted from water rushing over a waterfall and from the regular patterns of the ocean's tides. The energy that propels waves forward in the oceans can also be extracted and used. But can wave energy power plants be built anywhere there is water? In this energy science fair project, you will use ocean buoy data and mathematics to determine which locations along the coasts of the United States can sustain a wave… Read more
CD Burning: Take it to the Edge
Science Fair Project Idea
Scientific Method
Did you know that you can tell how much information is on a CD-R without even using a computer? Find out how in this "reflective" experiment. Read more

Center of a Shape Science
Blog Post
In this family STEM activity, students experiment with a simple technique that can help them determine the center of a shape. Grab some paperclips and string to explore! In this week's family science activity, students learn how to find the "middle" or "center" of a two-dimensional shape. It can be easy to locate the center of a symmetrical shape like a circle or a square, but finding the middle of an irregular shape can seem tricky. With a bit of science, kids can pinpoint the center of any… Read more
