STEM Tuesday — Chemistry ROCKS! — Interview with Author Kathy Ceceri

Welcome to STEM Tuesday: Author Interview & Book Giveaway, a repeating feature for the fourth Tuesday of every month. Go Science-Tech-Engineering-Math!

Today we’re interviewing Kathy Ceceri about her chemistry-infused book, EDIBLE INVENTIONS: Cooking Hacks and Yummy Recipes You Can Build, Mix, Bake, and Grow. PickaGoodBook.com says,”this book is such a great source to explore and learn through science and more.”

Mary Kay Carson: How did Edible Inventions come to be?

Kathy Ceceri: I have to credit my friend Miguel Valenzuela, inventor of the PancakeBot, a kind of 3D printer for making cool designs with pancake batter. I had written two books for Maker Media — Making Simple Robots and Paper Inventions — and gotten good feedback from educators and families looking for low-tech projects to help kids learn about STEAM (Science, Technology, Engineering, Art, and Math) concepts. I ran into Miguel at World Maker Faire New York — one of the worldwide celebrations of creativity in tech produced by Maker Media — where I was a speaker, but also casting about for inspiration for my next title. Miguel suggested I focus on food projects, and I roped him into a creating one of them — a hand-powered Lego version of the PancakeBot that lets kids “draw” with icing on cookies. The other projects touch on a wide variety of science and technology, with a heavy emphasis on chemistry, of course!

MKC: What was it like developing all these projects?

Kathy: Like most science experimentation, this one involved a lot of mishap! I spent several days trying to build an edible Rube Goldberg machine that included cucumber slice “dominoes” and a marble run using celery stalks and cherry tomatoes, but in the end it proved too difficult to coordinate all the moving parts. (You can see a test run video here.) More successful was the cardboard box solar oven. After going through several iterations, I finally developed a design that got hot enough to bake a chocolate cake! One of the things I loved about this book (and all my books, really) was learning a bunch of new stuff. For instance, thanks to a tip from another friend, flour expert Amy Halloran, I discovered that housewives used to make their own baking powder from chemicals they got at the local pharmacy. But probably the best part of creating Edible Inventions was getting to eat the results!

MKC: Why do you choose to write STEM books?

Kathy: My background is as a journalist. Over the years, I’ve written for local newspapers, magazines such as Sesame Street Parent, and websites such as Wired.com (where I helped create the GeekMom blog) and About.com (now Thoughtco, where I was the Homeschooling Expert). I’ve covered education, child development, history, art, and science — but I’m not an expert in any of those areas. You could say my expertise is in digging up background information research, finding the right people to talk to, and asking the right questions. My real talent is knowing how to distill what I learn into a form that’s easy for anyone to understand.

Kathy Ceceri is the author of over a dozen books of nonfiction for middle grade readers that teach STEAM along with history, geography, literature, and culture. Her hands-on projects have been used in classrooms and enrichment programs across the country and around the globe. Visit Kathy at Crafts for Learning, and follow her on Twitter @kathyceceri for sneak peeks of works in progress and links to her free online tutorials (including how to make Juicy Edible Gel Dots from Edible Inventions)!

I began focusing on STEAM (the “Art” is an important aspect to me!) after educational publisher Nomad Press asked me to do a book on robotics. Because my then-teenage oldest son was exploring robotics at the time as part of his homeschooling studies, I had spent a couple of years jumping on any opportunity to interview robotics engineers and designers. So I already had a good grasp of the basics, and a contact list of experts who were kind enough to let me pick their brains for topics and project ideas. I discovered I really enjoyed the process and I’m good at it, so I’ve continued writing about STEAM topics even after my kids grew up and moved onto other interests!

Today I teach crafts-based electronics and enrichment programs for kids and teens, and present hands-on professional development workshops for teachers and librarians. I’ve also worked with the Girl Scouts of the USA on their recent line of Robotics badges and their first-ever Cyber Challenge, coming this fall. All of these experiences help me keep in touch with what students and educators want to know about STEAM topics and ensure my writing is fresh and relevant.

MKC: To whom did you imagine yourself writing to while drafting the book?

Kathy: All my books are written for readers with little to no knowledge about the topic. That’s where I am at the start, too. So I can recognize the places where beginners are going to need some hand-holding and encouragement. I always try to relate concepts and techniques to things the reader is already familiar with. With robots, I use familiar materials like cardboard and duct tape. With Edible Inventions, I included a chapter featuring recipes that used standard ingredients and techniques to create unexpected textures and flavors (sort of like Molecular Cuisine, but using things you could find in any supermarket or natural food store). What makes my book different from an ordinary cookbook is that I emphasize the science. How does whipping an egg white turn a gooey liquid into a stiff meringue? Why do juice-flavored gelatin dots change color when you plop them into lemon-lime soda? And what’s the chemical reaction that causes watermelon lemonade to foam up and bubble over when you add a touch of baking soda? Readers get to learn about chemistry while making tasty snacks — what could be better?

MKC: What’s your current project and how are you tackling it?

Kathy: My next book, Bots! from Nomad Press, is an update on my original 2012 book Robotics. It contains several new projects and topics, as well as old favorites. As with every book I write, I try to approach the topic from as many different angles as possible. I firmly believe that showing how science relates to other kinds of creative activities helps bring in people who might not otherwise give it a try. So along with engineering, electronics and programming, there’s a “kitchen chemistry” robotics project that shows you how to make edible, stretchable robot skin! And like most of my projects, it ties into actual research — in this case, researchers who are trying to make inflatable robots that can crawl or slither into hard-to-reach areas. They hope their edible robots could help rescue lost explorers trapped in a cave, for example, and provide nourishment after sending back data about their location. You can see video of my homemade edible inflatable robot here. Bots! comes out in October 2019.

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!”

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.

The O.O.L.F Files

The Out Of Left Field (O.O.L.F.) Files this month take a look at close look at chemistry from all angles, from industry to academics to studying for med school. Plus, what’s a look at how Chemistry ROCKS! without a look at the chemistry of rocks?

 


 

 

STEM Tuesday — Chemistry ROCKS! — In the Classroom

 

Having majored in chemistry in college and then going on to teach the course a couple of times, I know how difficult this topic can be for students to understand. But really, chemistry is just the science of what matter is made up of and how it interacts with other types of matter. See? Not so hard at all. 🙂  I get it. Some students need to have more to help them become more comfortable with chemistry.

Here’s a list of things you can try:

Hands on Interaction:  I like to tell my students that the best way to understand chemistry is to think of it like cooking. Say you’re going to make a batch of chocolate chip cookies. You need the ingredients: the flour, sugar, butter, eggs, vanilla, and chocolate chips. Those are all different parts of matter. Then you mix them together with a certain amount of force by stirring or using a hand mixer. That gives you the cookie batter– a different kind of matter, but the chemical change hasn’t happened yet. Finally, you put the pan of cookie batter into the oven and voila you have cookies. Can’t you just smell the warm chocolate fresh out of the oven and imagine the first bite of gooey chocolate-y goodness?

 

 

During the whole process you are mixing and combining different kind of matter, but it isn’t until you apply heat that the chemical change takes place and you have cookies. Yum! This is a great way to get your students comfortable with chemistry.

 

Unfortunately, it’s not  possible to make cookies with your students in the classroom. Is there a substitute? Yes! Use these books. While it won’t get  you a warm chocolate chip cookie to eat in the end, you can do some pretty cool experiments with food.

Edible Science by Jodi Wheeler-Toppen (NGKids, 2015) is chock full of awesome food experiments! Many of these can be done in the classroom. Try the “Inflatable Marshmallow” on page 42. Kids learn about air pressure by watching a marshmallow expand and contract.

Another awesome one is watching how plants get water (page 9) by placing pieces of lettuce into bowls with different colored water (from food coloring). After a few hours students will see how the lettuce absorbed water through its leaves

My favorite one, though, is making slime (page 60). Your students will love it! This book is also great for homeschoolers since you can do a lot of the experiments in your very own kitchen. Happy experimenting!

 

Kathy Ceceri’s Edible Inventions: Cooking Hacks and Yummy Recipes You Can Build, Mix, and Grow (Maker Media, 2016)  also has some amazing experiments for kids to do with chemistry. She, however, goes a little more out-of-the box and discusses how kitchen gadgets can be used to make butter makers. She ventures into creating gelatin dots, and even agar noodles (don’t eat those!).

Finally, there is a whole discussion of 3D food printing and she gives you instructions on how to use your name-brand building blocks to make your own 3D food printer! Wow! This one is definitely for the more adventurous chemistry cook in your house. It will provide hours of fun.

After they perform each experiment have them analyze their outcome and discuss what happened. This is exactly what real scientists do. 

Questions could include:

  1. Did you get the outcome you wanted
  2. If not, why do you think this happened
  3. Could you repeat this experiment and get the same result? Why or why not?
  4. How is your result different from another team’s? Explain

By asking questions of your students you can help them to create a model to explain what happened. Perhaps they will end up changing the procedure or adding some requirements of their own, ie. use a hand mixer not a spoon to get a smoother consistency for the product.

 

 

2. Add some Fun Facts to your Experiments

Looking for a way to give your students a little more explanation of chemistry terms, and maybe a little history of the subject? Check out these titles, Explore Solids and Liquids! with 25 great experiments  by Kathleen M. Reilly (Nomad Press, 2014) and Explore Atoms and Molecules! with 25 great experiments by Janet Slingerland (Nomad Press, 2017)  have awesome experiments, but also contain explanations to describe the different parts of chemistry.

They have timelines the show the discovery of important scientific events, and also easy-to-understand definitions of words such as atom, molecule, solid, liquid, gas, states of matter, and mixtures and compounds.

These highly energetic texts and enthusiastic illustrations will grab your student’s attention and the experiments are all easy to do. Just follow the directions and you will have a great time in your classroom or homeschool environment.

After reading this book and doing some of the experiments, have students come up with their own examples of matter, molecules, and solids, liquids and gases. 

  1. Ask them to identify these different parts of matter in the things they see around the room or around their house
  2. Did they come up with something that can be both solid and liquid? How would they classify that?
  3. Discuss the types of conditions that might cause these substances to change from one to another.
  4. What types of evidence do they have to indicate the change

 

3.  Tie Chemistry to Literacy

If you have older students who are ready to learn more about chemistry, have them read The Disappearing Spoon by Sam Kean (Little, Brown BFYR, 2018).  This book gives a lively and interesting history of the scientists who discovered the different elements of the periodic table.

Discovering an element is not as easy or amazing as you might think. In fact, it can be downright dangerous to your health. Ask Marie Curie. Many of these stories are about scientists who defied all odds to come up with a new element or perhaps stumbles upon it accidentally. It is a compelling read for anyone who is interested in becoming a scientist as it gives a behind-the-scenes look at real-life challenges many of the scientists faced.

After reading this book, have your students break up into discussion groups.

  1. Each group can choose a scientist or element and come up with a way to present it to the rest of the class.
  2. Maybe they dress up as the scientist and have them talk about their challenges
  3. Infographics or posters can show their process
  4. Be sure to include the pros and cons of each element (some of them are quite dangerous to humans)
  5. Have them show the element as it is used today (hint: it’s not just a two-letter symbol on a chart)

This is a great way to promote discussion about the periodic table in a place other than the science classroom!

 

Whatever way you choose to introduce chemistry into your classroom or homeschool, remember one thing, HAVE FUN with IT! Students will get enthusiastic about a fun, interactive, presentation and who knows, you may just inspire a future generation of STEM/STEAM careers.
