Can you design something for someone else?


What does it take to design something for another person?

If you could replace someone's hand with something else, what would it be? What would it do?

Get creative, brainstorm, put your ideas down on paper! 


Find at least 2 creative ideas for replacing someone's hand with something else.

One idea could be an automatic door opener.

Write down all of your ideas in your Inventor Notebook.

Build Your Prototype


Build 2 ’hands’ and an arm that does whatever you’d like.

Visit the building instructions page for inspiration.


Program & Test Your Models


Create a different program for each prototype.

Use a fair testing method to compare the prototypes.

Which prototype is the best?


Describe what your best prototype is good at (or not so good at) and whether it does what you’d imagined. 

Think about how you did.


What did you do well? Is there something that you could’ve done better?
