Have you ever thought about the sheer number of words that exist in the English language to describe sounds? A noise can be a thud, a clang, a bang, a pop, a crash, a splash, a clatter, a buzz, a tinkle, and many more! You can probably think of an example for each of these—but if you heard the sound, could you say what produced it? Read more
Create a Marshmallow Map of Your Microwave Oven!
STEM Activity
Have you ever bitten into a microwave burrito, and the first bite is scalding hot, whereas the second bite is still frozen? If you’ve experienced this, then you know that microwaves have hot and cold spots, which is why they usually have a rotating tray to ensure that your food is evening cooked. In this activity, you’ll use marshmallows to map out where the hot and cold spots are in your microwave. Get ready to heat things up! Read more

Do you like gift wrapping? If you do, you have probably curled a ribbon with scissors before. Have you ever wondered why the ribbon curls when you run a scissor blade down one side of it? The answer is that when you apply pressure on the ribbon with the blade, the outer layer of the ribbon stretches and expands. This makes the outside layer of the ribbon longer than the inside layer that is pressed against the blade. As a result, the ribbon starts to curl to make up for the different lengths of… Read more

Did you know that the seaweed you've seen in the ocean or even eaten as a snack is inspiring innovators to imagine new materials? Large brown algae, like kelp, contains polymers—long chains of molecules—that are more environmentally friendly than the ones in most plastics. These natural polymers (alginates) could eventually be used to create sustainable everyday objects. Try your hand at using a bit of chemistry to turn biodegradable polymers from algae into your own custom… Read more

When we think about diapers we usually think about babies, because most of us wore them when we were babies and now maybe our siblings or friend’s siblings wear them. But did you know that astronauts also have to wear diapers sometimes? Astronaut diapers are called Maximum Absorbency Garments (MAGs), and astronauts wear them when they have to stay in their suits for long periods of time, such as during spacewalks, or as their ships are re-entering the atmosphere.  For babies and for… Read more

To slow the spread of COVID-19, the CDC recommends wearing a mask or cloth face covering—particularly in places where it is impossible to maintain social distancing (staying at least 6 feet away from others). This recommendation is for everyone age two or older (children under the age of two should not wear masks). Many instructions to make your own mask are available online. This activity will help you think through the process of designing and making a mask as an engineering problem.… Read more

Most modern smartphones and video game controllers have a built-in accelerometer used for motion control. In this project you will program an Arduino® to use an accelerometer to control the steering of a miniature popsicle stick drone. See this page for a complete list of our mini drone projects. You may wish to do the projects in order. Read more

Have you ever wondered if your preferences bias the choices you make? You make choices all the time, whether you are aware of them or not. Many different factors probably work together to affect the option you end up choosing. Which do you think are the most important? Everyone has personal preferences, and these may affect the choices we make. What about your favorite color? You may prefer one color over another for no good reason, other than the fact that you like it—or you may have… Read more

Have you ever wondered if people of all ages love sour foods, or if age correlates with this preference? There are a lot of different kinds of sour candies and drinks you may have seen advertised before, some having only a mild sour flavor and others that are truly mouth-puckering! In this activity you will investigate if there is a difference between the sour preferences of kids and adults. If you developed a super-sour food, to whom would you try to sell it? Read more

Have you ever noticed that some people are a lot pickier about the food they eat than other people are? They might be more selective because they are supertasters! To supertasters, the flavors of foods are much stronger than to average tasters. Whether or not someone is a supertaster comes down to the taste buds on his or her tongue, and you can actually investigate a person's supertaster status by looking at this. Are you a supertaster? Find out with this tongue-based activity!    Read more
Does Wet Hair Float or Cling?
STEM Activity
Have you ever noticed how hair moves freely when it is under the water, but clings together as soon as it emerges out of the water? Not only human hair does this; when wet dogs shake themselves after a swim, their hair clings together in strands. Try this activity to see why wet hair is far less fluffy than dry hair! Read more
