Today we did a design challenge that would allow us to use our knowledge of force.  The challenge was called Air Lift.  The groups were given 2 books, 4 baggies, and 4 straws.  They were given the challenge of lifting the books off the desk without touching them.  Congratulations to Ellorie, Elijah, and Bailee.  Here are some of their winning observations.
"We used the straw to blow air into the bags so the force of the air lifted the books." Ellorie
"We had to make sure the bags were half way under the books."Elijah
"We had to make sure the straw was under the books and the bag was sealed tightly."Bailee
