STEAM CHALLENGE 

Welcome to the Standing Human Structure challenge! This amazing STEAM challenge invites you and your students to step into the shoes of a bio-mechanical engineer to explore the fascinating relationship between balance, center of gravity, and structural stability. It is ready to use, no prep, and best for engaging kids in a hands-on way to teach about physics, balance, and the law of math. Whether you are designing for robotics, prosthetics, or creative art, understanding how weight distribution allows a figure to stand independently is a fundamental skill in physics and design. By experimenting with these materials, your students will learn firsthand how to manipulate forces to create a human-like model that is as stable as it is creative.

Objective

Understand balance, gravity, and stability in simple structures, and how the size and weight of body parts help the body stand properly, and how forces affect standing objects in physics.

Real-World Problem

Many human-like structures—such as robots, mannequins, toys, and prosthetic models—will collapse if they are not balanced correctly. Engineers must carefully design these structures so they can stand independently and move dynamically without losing their center of gravity.

The Challenge

Your mission is to build a Standing Human Structure that meets the following criteria:

• Stands independently without any external support
• Maintains stability and does not fall for at least 10 minutes
• Features movable body parts (arms and legs)
• Reflects creativity and a polished, aesthetic design

Materials

• Straw pieces
• Pipe cleaners
• Scissors
• Stopwatch (optional)
• Pom poms optional
• Ruler

Project Requirements

To successfully complete this challenge, ensure your model follows these strict guidelines:

1. Self-Supporting: The structure must stand on its own without propping.

2. Human Representation: The design must clearly resemble a human form.

3. Dynamic Parts: Both arms and legs must be fully movable.

4. Quality Craftsmanship: The model should look neat, creative, and aesthetically pleasing.

5. Endurance: The structure must remain standing for at least 600 seconds.

 Instructions:

1. Gather at least 4 pipe cleaners (standard size).

2. Take 6 straws.

3. Cut all 6 straws into small pieces, approximately 1 inch (2.5 cm) long.

4. Your materials are now ready for the activity.

Steps:

Take one piece of straw and one pipe cleaner. Insert the pipe cleaner through the center of the straw piece. Adjust it so that the straw is exactly in the middle and both ends of the pipe cleaner are equal in length.

 

Next, take another pipe cleaner and insert it through the same straw piece. Again, make sure the straw stays in the center and that both ends of this pipe cleaner are equal in length.

Now, on the other half pipe cleaner, shape the body by inserting straws into the pipe cleaner, then twisting the pipe cleaner around the straws to secure everything in place.

Insert the straws into the pipe cleaner to create the legs. Bend and twist the bottom of each leg to form small feet. You can fold the ends into a triangle shape or simply bend them into two small feet to help the figure stand. It is all up to your creativity.

Continue twisting the pipe cleaner to form the neck and then create a head at the top.

Take another straw and thread a second pipe cleaner through it to make the arms. Attach the arms to the body by wrapping and twisting the pipe cleaner securely around the torso.

It is an open-ended activity. You can make what you want to create first.
