Making a Sugar Thermometer

STEM Activity

1 review

Bakers (and those who help bakers!) know that at some point in every baking recipe, the instructions will tell you to preheat your oven to a certain temperature. But if you’ve ever tried to bake cookies and they come out flat, or take too long, it’s possible that your oven is to blame. You might set your oven to 350°F, but how do you know that the inside of your oven actually reaches that temperature? You could use a thermometer…. or you could use sugar! Because we know… Read more

Marble Race – In Liquid!

STEM Activity

11 reviews

Have you ever tried to squeeze honey or syrup out of a bottle at breakfast on a cold winter morning? Do you notice that it's harder to do that than on a hot summer day? As the liquid gets colder, its viscosity, or resistance to flow, increases. Viscosity is a properly of liquids that can be hugely important in wildly different applications – from how the syrup flows out of your bottle, to how blood flows through the human body, to how lava flows out of a volcano. In this project you will… Read more

Memory Surprises

STEM Activity

Have you ever wondered why some things are easy to recall, while others need hours of study? For example, you might be able to recollect what happened at your birthday party without any practice, but you need hours of study before you can recite a few lines for a theater play. Our mind stores and remembers information in fascinating ways. Remember to do this activity and you will be surprised at what your memory can do for you! Read more

Make String from Algae

STEM Activity

215 reviews

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

Pass the Cranberry….Volcano!

STEM Activity

4 reviews

While you might enjoy cranberry sauce, if you’ve ever tasted a real cranberry you were probably surprised by the taste – definitely not as sweet as the sauce! Cranberries and cranberry juice are very tart to eat, but they can be delicious when combined with other ingredients (such as orange zest and sugar, or cranberry muffins!). Cranberries add tartness to these foods because they are acidic, similar to lemons or limes. Foods that are acidic will usually taste sour or tart,… Read more

Password hacker

Play a Memory Game with Your Nose!

STEM Activity

5 reviews

Take a deep breath: freshly baked cookies, smoke from a wood fire, or a bouquet of roses—your nose is an amazing smell detector! Your sense of smell can not only identify a huge variety of odors, but it is also incredibly sensitive. Think about how easily you can detect if someone in your neighborhood has a barbecue just by smelling hints of smoke from a faraway grill. But how good is your nose when it comes to differentiating individual smells? Do this activity to find out! … Read more

Porosity and Particle Size

STEM Activity

Have you ever heard the expression, "solid as a rock"? As it turns out, rocks are not entirely solid. Rocks actually have tiny pockets of air inside them. This is obvious when you look at a piece of volcanic rock (often called basalt), which is full of visible holes. But dense rocks, such as granite, have tiny air pockets inside them, too. These pockets of air are just much smaller. If you picked up one volcanic rock as well as one granite rock of the same size, you would notice they don't… Read more

Program Drone Steering with an Arduino®

STEM Activity

14 reviews

How do quadcopters (drones with four propellers) steer? Find out in this fun project as you program an Arduino to steer a mini 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

Put Your Peripheral Vision to the Test

STEM Activity

4 reviews

Did you know we use our side vision for many daily activities, like riding a bike, reading or playing basketball? Few people realize they are even using it. Our survival once depended on the quick response of our peripheral vision. A detailed picture, created by our central vision, is only useful in situations where time allows us to focus on the details. But our side vision can help us avoid dangers quickly. In this activity, you will find out how specialized our peripheral, or side vision, is. Read more
