STEM Tuesday– Coding– In the Classroom

Although I studied Electrical Engineering in college, I ended up spending most of my time as an engineer working with code. I love coding, and I’m happy to see so many great books about coding for young readers. Here are the books I read.

Coding Games in Scratch: A Step-by-Step Visual Guide to Building Your Own Computer Games
by Jon Woodcock

I love Scratch. It’s a block code, meaning you put the commands together rather like Legos. The code blocks are designed to help keep you from putting the code pieces together wrong. This book does a great job of walking you through the building of computer games in Scratch. If you want to learn basic coding concepts while making fun games, check out this book.

This book is packed with information and activities for learning about coding and the web. It even has a related web site – – to help you through the missions.


Bonus Book: Hunting the Cyber Trail: Be a Computer Forensic Scientist
by Alix Wood

Follow a fictional computer forensic scientist as he searches computers for clues to the whereabouts of two missing kids. I love that this book gets into how information is formatted within computers, something I dealt with a lot when I was programming. This book also has lots of activities that are computer-related, but don’t require a computer to complete.

Now for some other activities you can try to get you into a programming frame of mind.


A computer program is basically a how-to for a computer. Programmers put together instructions that tell computers what they need to do.

A great activity as you start programming is to write a how-to. This could be a recipe, instructions for completing a craft, or instructions for something you do every day, like washing your hands. Once you’ve created your how-to, have someone try to follow your instructions. That’s when you find out if you forgot any instructions or if anything was unclear.


Flow-charts are really useful tools for programmers. They’re a graphical representation of a process or algorithm. Learn about flow-chart symbols and create a flow-chart for a process or algorithm. Here are some resources to help:

Explore ASCII

Remember me mentioning the formatting of information in computers? Well, one of those things is called ASCII – American Standard Code for Information Interexchange. It is a way to represent text characters using numbers. This is generally written in hexadecimal (base 16) numbers.

To learn about hexadecimal, read the beginning of this article: or this: You don’t have to get too deep into hexadecimal to work with ASCII.

Use an ASCII table (either from p. 24 of “Hunting the Cyber Trail” or here: (There are lots more versions out there if you want to find something different.)

Get the hang of ASCII by converting your name into hexadecimal ASCII code. Then, write a full message and give it to a friend. See if they can decode your message.

There are lots of great resources out there that support programming. One of the biggest is They have fabulous activities there, including a bunch that don’t require a computer:

STEM Tuesday– Material Science– Interview with Author Jennifer Swanson

Super Gear Book


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

Today, I’m delighted to interview the founder of STEM Tuesday, Jennifer Swanson!

Jennifer is a huge fan of STEM and loves to write about technical topics. She did just that in her SUPER GEAR: Nanotechnology and Sports Team Up! book with Charlesbridge Publishing.

Super Gear Book



A book about nanotechnology and sports… how did you put those two topics together? 

  Well I’ve always loved technonogy and I love sports, too. In fact, I’ve played tons of sports my whole life. Those I haven’t played, I’ve watched. I’m a huge fan of the Olympics, too. We used to watch it as a family. Do you remember when Michael Phelps wore that full-body swimsuit in the 2008 Beijing Olympics? I do! It was fabulous and he won tons of medals with it. So did his teammates. Sooo many records were broken that year. I was definitely intrigued. What was that amazing swimsuit made of? Turns out, it was developed with nanotechnology. 

Did you know anything about nanotechnology at the time? 

Not much. But as I said, I was very intrigued by the suit, so I set about learning more. That’s how I am with pretty much all of the topics I write. I read about something cool in the news and I just have to learn more about it. You know, understand how it works and also WHY it works. Usually as I learn more, I get really excited about the technology and all of the applications it has and then, well, I have to write about it. That’s what happened with this book!

Nanotechnology is a pretty technical topic. Was it difficult to sell this idea?

Sort of. I mean, when you have a fairly technical topic, you really have to come up with a great hook. One that will cause even people who aren’t interested in STEM to be intrigued by your topic. The best way I’ve found to get editors and agents interested in technical topics is to put the hook in the title. A great title grabs their attention fast! And that gets them to read the rest of your proposal. So, that’s a good first step. (Of course, the writing is everything, so the rest of your proposal has to be written well, too). 

What are some cool things you learned about sports and the nanomaterials that are used in them?

First of all, this book came out a few years back, so the applications for nanomaterials have actually expanded significantly since then. Nanotechnology is used to create almost all of the materials in many different sports. It allows for stronger, more durable, and yet flexible materials, which then support athletes in their performance. 

For example, golf is one sport that uses a lot of nanotechnology in its materials. Everything from the dimples on the ball, to the core inside the golf ball, to the head and shaft of the golf club is specially designed with nanomaterials, like carbon fibers. This allows players to hit the ball farther, higher, and with much more accuracy than ever before. Just do an internet search of golf balls and nanotechnology and see how many different balls use the words nanotech or carbon fibers, or graphene. It’s pretty incredible. 

Nanotechnology is in so many other objects, too. How did you decide on sports as your focus? 

Well, aside from loving sports, I figured that was my biggest hook. Yes, nanomaterials are used in many objects in medicine, recycling, and even in energy. But the one topic I thought might most resonate with kids was sports. 

And then I played up that connection in my proposal. I did a search for sports words and phrases like Team Up! and Play Ball and Tee it Up, etc. I find that makes people smile when they read and also shows that I did my research on the topic. 


What would you like readers to take away from your book? 

I hope they find nanotechnology as exciting as I do. That they learn about these cool materials and also that they think about the engineering that made them every time they pick up a bat, golf club, tennis racket or put on a swimsuit.
