How Antibiotic Resistant Bacteria Take Over

STEM Activity

7 reviews

Have you ever had to take antibiotics? Your doctor probably told you to finish taking all the pills even if you felt better after one or two days. But why is that? Why shouldn't you stop taking antibiotics as soon as you feel better? You might be surprised to hear that if you do, you might contribute to the creation of antibiotic resistant "superbugs!" Find out how these superbugs can develop in this activity by rolling dice to model how different bacteria respond to an antibiotic treatment. Read more

How Does a Chick Breathe Inside Its Shell?

STEM Activity

19 reviews

Have you ever wondered how an unborn chick breathes inside its shell? Every animal needs oxygen to live, so the chick must get air somehow! When an animal—including a human—inhales, oxygen enters its lungs and is then distributed to all the different parts of its body. The animal's metabolism converts the oxygen into energy. During this process, a waste gas called carbon dioxide is produced. To get rid of it, the carbon dioxide is carried back to the lungs, where it is collected… Read more

Make String from Algae

STEM Activity

225 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

Keep Your Candy Cool With the Power of Evaporation!

STEM Activity

12 reviews

Have you ever wondered how sweating helps keep you cool on a hot summer day? Sweat, which is mostly water, cools us down when it evaporates. When water evaporates, it changes from a liquid to a gas. The gas carries away heat with it, helping to remove heat from your skin. Not only can evaporation cool down your body, it can also cool down other things, such as chocolate. Heat on a hot summer day can turn your solid candy bar into a gooey, melted mess, but how well can evaporation keep your… Read more

Liver Stinks!

STEM Activity

7 reviews

Your liver is important for cleaning up any potentially dangerous substances you consume. But how does it do it?—With a little help from some complex chemistry. Within your liver, as within every tissue in the body, many chemical reactions occur. Often these reactions require "help" to happen at a faster speed, and this can be supplied by enzymes—tiny types of proteins. The liver uses specialized enzymes to help it break down toxic substances and make them safer for the… Read more
