Coding for a Cause: 4th Graders Program Natural Disaster Preparedness in Scratch

What happens when science, writing, and computer science collide? In fourth grade, it looks like powerful learning — and a lot of thoughtful coding.

Studentsin Ms. Henriksen's 4th grade began by exploring different types of natural disasters — what causes them, where they happen, and most importantly, how people can stay safe. From earthquakes and hurricanes to floods and blizzards, students researched the science behind these events and discussed the real-world impact they have on communities.

But they didn’t stop at research.

Turning Knowledge into Code

Using Scratch, students transformed their learning into interactive conversations between two Sprites. Their challenge:

Create a coded dialogue where one character teaches the other about:

What the natural disaster is, How it happens, Safety and preparedness strategies

This project blended multiple skills:

Science understanding of natural disasters

Informational writing through clear dialogue

Computer science concepts like sequencing, events, and message passing

Digital communication through audience-friendly explanations

Students carefully sequenced their scripts using broadcast messages, “say” blocks, timing, and sprite changes to make their conversations flow naturally. They quickly discovered that coding a conversation requires precise sequencing — if one block is out of order, the dialogue doesn’t make sense!

Projects like this show students that technology is more than entertainment. It’s a tool for communication, creativity, and problem-solving. Through Scratch, they weren’t just coding — they were building digital public service announcements designed to educate others.

Fourth graders proved they can:

Research responsibly

Write with purpose

Think computationally

Create with intention

From natural disasters to digital dialogue, our students coded with purpose and created projects that truly matter.

Massachusetts DLCS Standards Addressed (Grades 3–5 Band)Computing and Society (CS)
3-5.CS.1 – Identify and describe ways people use computing technologies to address real-world problems.(Students created projects that teach disaster preparedness — a real-world safety issue.)3-5.CS.3 – Explain how computing devices and applications can support communication and collaboration.(Students used Scratch to communicate important safety information.)
Digital Tools and Collaboration (DT)
3-5.DT.1 – Use digital tools to create and communicate content.(Students designed and coded interactive conversations.)3-5.DT.2 – Use appropriate digital tools to collect, organize, and present information.(Students researched disasters and presented their learning through dialogue.)
Computational Thinking (CT)
3-5.CT.1 – Decompose problems into smaller parts to facilitate the design of a program.(Students broke their project into research, script writing, coding dialogue, and debugging.)3-5.CT.2 – Create programs that use sequences, events, loops, and conditionals.(Students sequenced conversations using events, broadcast messages, timing blocks, and conditionals where appropriate.)3-5.CT.4 – Test and debug a program to ensure it runs as intended.(Students refined timing and message passing so conversations flowed correctly.)
Computing Systems (CD)
3-5.CD.9 – Use appropriate terminology to describe steps in algorithms and programs.(Students discussed blocks, sprites, scripts, broadcasts, and sequencing.)

Digital Citizenship

Digital Detectives on the Case:Investigating Our Digital Footprints

What do fairy tales and digital citizenship have in common? Quite a lot, according to our fourth and fifth graders!

Recently, students stepped into the role of Digital Detectives, taking part in a fun investigation to solve a mystery in Fairyland. Someone had stolen a valuable item, and the only clues were the digital footprints left behind. By examining messages, online posts, and shared information from different fairy-tale characters, students worked together to determine who the thief might be.

This engaging activity, created by Zak Kolar (see below), helped students see that our actions online leave tracks—just like footprints in the snow. Every post, comment, search, or shared photo can leave clues about who we are and what we do.

As detectives, students practiced looking closely at evidence, discussing possibilities, and explaining their reasoning. More importantly, they began to understand that their own digital choices matter. The conversation naturally led to ways students can make safe, responsible decisions and protect their digital reputations.

Activities like this help digital citizenship feel real and memorable. When students actively investigate and solve problems, the learning sticks—and they begin to think more carefully about the trails they leave behind online.

Essential Questions

What is a digital footprint, and how is it created?

What can someone learn about us from the information we share online?

How can we make responsible choices to create a positive digital footprint?

Massachusetts DLCS Standards Addressed (Grades 3–5)

This lesson supported elements of the Digital Citizenship and Safety strand, including students’ ability to:

Explain that information shared online contributes to a digital footprint that can be searched, copied, and shared.

Demonstrate responsible and respectful behavior when using digital tools and online spaces.

Identify strategies for protecting personal information and making safe choices online.

Digital Citizenship

Keeping Private Information Private:Learning Digital Safety in Grade 3

Recently, third-grade students learned about an important digital citizenship topic: staying safe online by keeping private information private. As students become more independent users of technology—both in and out of school—it’s essential that they understand how to protect themselves in digital spaces.
During this lesson, we focused on helping students recognize what private information is and why it should not be shared online. Through discussion, examples, and guided practice, students learned to think critically about the information they see and share when using digital tools.
We explored questions like:What kinds of information are safe to share?What information should always stay private?How can we make smart choices if someone asks us for personal information online?
Students practiced identifying private information such as full names, addresses, phone numbers, passwords, and school details. We talked about real-world scenarios they might encounter in games, apps, or websites and what to do if something feels confusing or unsafe—including the importance of asking a trusted adult for help.
To wrap up the lesson, students participated in a Privacy Bingo game. This fun, interactive activity gave them the chance to reinforce key ideas from the lesson while collaborating with classmates. As students listened for clues and matched them on their bingo cards, they confidently demonstrated their understanding of how to stay safe online. The energy in the room was high, and it was clear that learning “stuck” when it was paired with play.
Digital citizenship skills don’t develop overnight—they grow through ongoing conversations, practice, and reflection. Lessons like this help lay the foundation for responsible, thoughtful technology use as students continue to learn and explore in digital environments.
