Charli's Dorsal Device

An Engineering Adventure

(Charli Explores STEM® #3)

 

What if one smart invention could help an animal return home?

 

Follow Charli as her curiosity leads her into the exciting world of engineering and innovation.

​

When Charli meets an engineer and learns how technology can help animals in need, she can’t stop wondering what it would be like to design something that truly makes a difference. Her imagination sparks when she learns about a rescued dolphin that needs help returning safely to the ocean. But the challenge is complex. The device must work underwater, stay secure, and protect the dolphin’s well-being.

​

As imagination turns into action, Charli steps into the role of an engineer—testing ideas, learning from mistakes, and improving her design through perseverance and teamwork. She soon discovers that engineering isn’t about getting everything right the first time, but about problem-solving, creativity, and determination.

 

With Charli’s help, readers explore:
• Engineering and STEM careers
• Design thinking and problem-solving
• How technology can help protect marine animals
• The importance of testing, failure, and redesign
• Confidence, resilience, and collaboration

 

Perfect for readers ages 6–9, this engaging chapter book encourages curiosity, critical thinking, and early interest in engineering and STEM careers. ​​​​​
