Hovering Hovercrafts

Hovering Hovercrafts Project Based Learning in Out-­‐of-­‐School Time Hovering Hovercrafts, Batman! Are they really doing this In Afterschool? Project Overview !   Teams of students will build a large circular Hovercraft powered by a leaf blower that they can ride. !   They will create a new way to travel…the future of transportation! Reflect Think about one of your most significant, most memorable learning experiences in your life.... What made it so? What made it powerful? What did you do? .

 S-­‐ cience  T-­‐echnology  E-­‐ngineering  A-­‐rt !  M-­‐athematics DO NOT TEACH DIRECTLY! The following information is intended for teacher content education purposes only, in order to help students see the science behind their explorations, designs, and thinking! Direct Teaching will surely cause students to tune out immediately and is against the out of school culture. Discovery Task #1: Mini-­‐Hovercraft Materials: Steps: •  1 CD 1. 
•  1 Pop Top 2.  Close Pop Top •  1 Balloon 3.  Blow up Balloon •  Hot Glue Gun (go to station) 4.  Quickly attach Balloon to pop top Hot Glue Pop Top to center opening of CD 5.  Release valve and Voila-­‐-­‐-­‐ Discovery Task #1: Mini-­‐
Hovercrafts Why does it Work? Pressed Gas = Pressure Discovery Task #2: Paper Tunnel Materials: Steps: •  2 books 1.  Place books side by side 3 inches apart •  1 piece of paper •  1 straw 2.  Place paper on top 3.  Point straw into Paper Tunnel and Blow 4.  What happens? Discovery Task # 2: Paper Tunnel Why does it Work? Fast Gas = Low Pressure Discovery Task # 3: Coke Can Pressure Materials: Steps: •  2 Coke Cans 1.  Place all straws together side by side •  10 straws 2.  Place each can on top of straws at each end 3.  Blow between cans 4.  What Happens? Discovery Task # 3: Coke Can Pressure Why does it Work? A Daring Example of Air Pressure…. Why does it Work? Quick Question: A set of points, in a plane, that are equidistant from a given point. What am I? .
