2nd grade Science and Engineering: Making Mobiles!

In Making Mobiles we learned the following science standards:
  • Create and use representational models to demonstrate stable balanced systems.
  • Construct and evaluate toys that demonstrate spinning, and explain how they operate.
Equipment List:
Straws, rubber bands, many paper clips, and note paper.

WE ARE SCIENTISTS!


I connected all the parts of my mobile to create balance in a system.  


Did you know that a mobile is a hanging system of balanced objects?

A mobile is stable.

Did you know that the Space Station is a kind of spinning mobile in space?
