In this STEM Challenge, you will build an igloo out of marshmallows

Question

Using straight toothpicks, can you create a dome-shaped igloo?

Materials

  • marshmallows
  • toothpicks

 

What to Do

  1. Take time to brainstorm your design.  Write down some notes or draw a picture.
  2. Create your design using the materials. 
  3. Does your igloo stand on its own without support on the inside?  

 

What is Happening?

An igloo is built with packed snow blocks.  The blocks are placed in a circular pattern spiraling all the way to the top.  Did you create a pattern in the design of your igloo?   

 

Activity add-ons:

Are there other materials you can think of that would add to the success of your igloo? What are they?  How would you add them to your design? Would these additions help your igloo stand on its own without support on the inside?
