STEM Tuesday– Tiny Worlds (Microscopic/Nanotech)- In the Classroom

This month’s STEM Tuesday theme revolves around the small, the tiny, and the microscopic—from nanotechnology to microorganisms. Microbes and fungus may be small, but their effects in the world are far from that. They are vital to Earth’s complex, constantly cycling systems, which range from microscopic to monumental. What could microbes do? Try this activity in the classroom to help students understand how microorganisms can have big effects.

 

Yeast + Sugar Balloon Experiment

Student Prep

Read through Tiny Creatures: The World of Microbes by Nicola Davies and It’s a Fungus Among Us: The Good, the Bad & the Downright Scary by Carla Billups and Dawn Cusick as a class. Then tell students that microbes are in everything from the soil to our bodies to even our food. Explain that they will be doing a microbial experiment using yeast (a microorganism that is a member of the fungi kingdom). Then distribute materials to groups of students.

Tiny Creatures: The World of Microbes by Nicola Davies

This book is perfect for the curious kid who wants to know how microbes work. All around the world—in the sea, in the soil, in the air, and in your body—there are living things so tiny that millions could fit on an ant’s antenna. They’re busy doing all sorts of things, from giving you a cold and making yogurt to eroding mountains and helping to make the air we breathe.

It’s a Fungus Among Us: The Good, the Bad & the Downright Scary by Carla Billups and Dawn Cusick

All about Fungus! Who wouldn’t want to read this book? In It’s a Fungus Among Us, you’ll meet the wild group of organisms that can turn ants into zombies and eat trillions of pounds of feces every day. They’re not all gross though, these are the same types of organisms that make cheese stretchy, add sour tastes to candy, and make bread rise!

 

Materials

  • empty clear water bottle
  • yeast packet
  • balloon (stretched out by inflating a few times)
  • warm water
  • 1 tsp. sugar

Steps

  1. Have students empty the yeast packet into the water bottle. Then tell them to pour some of the warm water inside. Students should move the bottle a bit to mix the yeast and water.
  2. Ask students to stretch the balloon over the water bottle opening and observe what happens in the next 5 minutes. They should record their observations.
  3. Next have students carefully remove the balloon. Tell them to add 1 tsp. sugar to the bottle and mix. Students can now put the balloon back over the bottle opening.
  4. Have students observe the mixture and the balloon over the next 20 minutes. They can record their observations ever 5 minutes.

Conclusion

As the yeast consumes the sugar in the warm water mixture, the microbes produce gas that inflates the balloon at the top of the bottle. Tell students that this process is called fermentation, which is a process used to make all kinds of foods that we eat. Bread becomes light and airy due to fermentation. Milk turns into yogurt or kefir because of fermentation. The fermentation process also helps humans and animals digest food. This is just one of the many examples of how microbes affect us on Earth.

 

Need more ideas for teaching middle-school students about microbes? Check out these resources:

  • BioEd Online, Science Teacher Resources from Baylor College of Medicine, Microbes
    This site has 12 lessons to help students investigate microbes related to health (bacteria, fungi, protists, and viruses). Students will learn that microbes have important roles in humans, and that some help while others cause diseases. http://www.bioedonline.org/lessons-and-more/lessons-by-topic/microorganisms/microbes/
  • Microbiology Society, Microbe Passports
    Students can check out a virtual microscope on this site to study different microbes—from Bifidobacterium (which lives in human intestines) to Geobacter metallireducens (a metal-eating microbe that lives in muddy riverbeds).

STEM Tuesday — Chemistry ROCKS! — Writing Tips & Resources

“CHEMISTRY! CHEMISTRY! CHEMISTRY!”

The crowd chants as the June sun sets on the western horizon. The emcee, DJ “Atom” Mick Orbitals, takes the stage to thunderous applause.

“Ladies and gentlemen…

ARE YOU READY TO ROCK?”

The crowd explodes with a roar like an alkali metal added to water. 

 

“Welcome to the Chemistry Rocks Summer World Tour 2019! Let’s rock!”

By https://pxhere.com/es/photo/41796 via Wikimedia Commons.

STEM Tuesday fans, sit back, relax with your favorite chemically enhanced or brewed beverage and enjoy the show.

Chemistry Rocks!

It really does. Qualitative, quantitative, organic, bio, physical, whatever or whichever, they all rock the scene. From the twitch of a muscle to the Fourth of July fireworks display to the explosion of the LH2 (liquid hydrogen) fuel that propels a rocket into space toward Mars, chemistry is there. Reaction after reaction after reaction occurring all around us every microsecond of every day. Sight, smell, taste, touch (If you think about it, we can also technically go with sound when we consider the neurochemistry involved in processing a sound wave) are all affected by chemistry.

Chemical Fun!

Don’t throw your shoe at me! I realize not everyone has had a positive experience with chemistry. I understand. I’ve been there. The struggle was real. I was only able to dig myself out of a “D” hole in high school chemistry because of the additions I was able to add to my science teacher’s herpetological and ichthyological collections for extra credit on the biology side of his classroom. I washed out of Chemistry 101 as an immature, baseball-playing freshman in college and it took three full semesters to dig out of that hole in my transcript.

Chemistry is hard. It’s one of those sciences that is like a completely foreign language. Like the Tower of Babel, one can be confused, frustrated, and want to throw a shoe at that one person who tries to tell you that chemistry is fun. As with language, once you learn the basics, begin to understand the meanings of the words, and learn to navigate those foreign roads, a whole new world opens up. With chemistry comes a new understanding of the world around us and how it operates. We are able to drive our existence toward a better life.

And where else can you perform experiments where colors change, states of matter are shifted, and there’s a potential for explosions?

Celebrate the Periodic Table! 

In 1869 Mendeleev proposed the first periodic table of elements. That makes the periodic table 150 years old! In my opinion, it looks just a fresh and vibrant at 150 as it did in it’s 20s. Maybe even better! I guess some things get better with age, right? I’ve always marveled at the beauty of the periodic table. Well, I marveled when I finally gave in, buckled down and learned the basics of the periodic table. The periodic table is a masterpiece. Just as The Beatles had Sgt. Pepper’s, DaVinci the Mona Lisa, Michaelangelo his sculpture of David, chemistry has the periodic table.

Happy Birthday, Periodic Table!

Better Life

Chemistry has made life better.

I’m sitting on my back patio as I write this section. It’s a beautiful early June Saturday morning. Chemistry surrounds me.

  • I see the cat eating his store-bought cat food, which has been optimized through a blend of macro and micronutrients. In other words, chemistry.
  • There’s the gardener table I built from my kids’ old wooden swingset that both got a recent coat of water sealant. Chemistry.
  • The house paint. Chemistry.
  • The cement of the patio. Chemistry.
  • The flowers and vegetables in pots and in the garden which were recently fertilized with BR-61. Chemistry.
  • I just ate a bowl of rice cereal made from a chemistry-based recipe. The peanut butter on my toast is loaded with chemistry. Heck, even the toasting of the bread by electrical heating elements in a closed chamber is chemistry.
  • I’m working at a steel patio table painted with a rust deterrent coating while typing on a laptop that relies on rare earth metals. Tell me that’s not some amazing chemistry!

I could go on and on but the point is this:

We are surrounded by chemical marvels every second of every day.

Chemistry makes our lives better.

Dark Side

There’s little argument as to the benefits chemistry brings to society. But to everything good, there’s always a dark side. The dark side of chemistry often is a result of our attempts to develop a fix to one particular problem without consideration of the entire ramification spectrum. Pesticides that are also potent carcinogens. Pharmaceutical chemicals with side effects that almost override the positive effects or cause addiction. Chemical weapons.

I could go on with examples of chemistry gone wrong but the point remains we need to be more vigilant with the power of chemistry. The current and future generations of chemists need to design chemical solutions with an eye to the long-term effects and cost-benefit of the solution. This particular solution may work to solve the issue BUT what else does it do?

Writing With Chemistry

I was going to title this section, Writing Chemically, but had second thoughts about the unintended connotations associated with that title. Most writers would classify chemistry as something on the opposite end of the creative spectrum than writing. I understand but hear me out before launching the other shoe at my head.

An ionic bond forms between two oppositely charged atoms when an atom with the weaker force donates an electron to the atom with a stronger force. Covalent bonds form between two atoms when they share electrons to fill their outer orbitals. Hydrogen bonds are weaker bonds that form when the partial positive charge of the hydrogen is attracted to a negatively charged atom. When thinking about the interactions between story elements or characters, chemistry provides three good ways to explore these interactions and reactions.

Or how about using the principals of exothermic (heat released) and endothermic (heat absorbed) reactions to move the plot forward in your story? You can also think about character development in the structural terms of chemistry, primary structure, secondary structure, tertiary structure, and quaternary structure. All four structures contain the same basic bits; it’s a matter of increasing the complexity of the model.  

See? The principles of chemistry can help out the writer as well as the chemist. Another win for science!

Explore Chemistry!

Bottom line: Give chemistry a chance because it really does rock.

The benefits far outweigh the detriments.

The rewards in understanding the fundamentals of chemistry are well worth the failures, false starts, and frustrations of the learning process.

We are all a whole lot better off with chemistry than without (and it doesn’t even matter if we don’t understand a lick of the science behind it).

Chemistry Rocks!

Now go enjoy the show.
