Calculating the Circumference of the Earth

Science Fair Project Idea

Scientific Method

How big a ruler would you need to measure the circumference of the Earth? Did you know that you can do it with a yardstick? (And you won't have to travel all the way around the world!) Read more

Can Copper Foil Snails?

Science Fair Project Idea

Scientific Method

If you have a garden, you probably know about snails (or their shell-less relatives, slugs). You may even be looking for a good way to keep them from getting into your garden and eating up the results of all your hard work. In this science project, you will take a scientific look at one method of discouraging this garden pest. Read more

Can You Crowdsource a Better School Environment?

Science Fair Project Idea

Scientific Method

How can you motivate students and teachers to make positive changes in their school? Why not try using what is in everyone's pocket—a smartphone! With this project you'll try your hand at harnessing the power of crowdsourcing and mobile technology by creating an app that motivates users to change their school for the better. Do not worry about the app creation, the MIT App Inventor tool makes that part easy; the instructions provided here will lead you through it step-by-step. Will your… Read more

Did you know that instances of miniature lightning can occur in your mouth when you bite on a hard candy? Would it not be fascinating if you could observe these light flashes? Life Savers® Wint O Green® mints might just be the tool we need to observe this science! Crush them, observe, and detect what makes the flashes visible. How many sparks can you see? Read more

Have you ever poured sand out of a bucket, or poured cereal out of a box, and noticed it is a lot like pouring water? It is because sand and cereal are granular materials. This means they are made up of solid particles, but they can actually flow like liquids! Candies, like Skittles®, M&M's®, Nerds® candies and many others, are also granular materials. In this science activity, you will investigate how the size and shape of granular materials affect how they flow. And what… 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

Carnival Game Science: Weekly Science Project Idea and Home Science Activity Spotlight

Blog Post

In this week's spotlight: a mechanical engineering experiment and family science activity that takes a scientific look at why a popular carnival game may look easy to win but may, in fact, be really difficult. How does the distribution of mass in the way milk bottles (or plastic bottles of colored water!) are stacked affect how hard or easy it is to knock the bottles over? Put the question to the test with your own home version of a classic carnival game! Knock Your Blocks Off: The… 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
