Welcome to ** TAME Engineering Adventures!** Every month we strive to bring you two engineering activities (this month we will provide one warm-up activity and one practice competition activity) that will help you challenge your students with hands-on learning.

This October’s Engineering Adventure is to construct a crane! We provide a terrific video from Curiosity Machine, which stars a Latina engineer illustrating both a simple crane and a complex crane with pulleys and a crank. Next we share the 2012 State Competition Engineering Design Challenge! It’s perfect for a pre-Divisional warm-up.

It’s a great way to get your Club members to start thinking like engineers in preparation for our STEM Competitions.

Warm-up Adventure: Crane Challenge

Have your students watch this video from Curiosity Machine, which stars a Latina engineer illustrating both a simple crane and a complex crane with pulleys and a crank. Provide supplies like string, disposable cups, tape, and drinking straws, then challenge your students to decide how they would build a crane of their own.

Competition Adventure: Aggie Crane 2012 State Challenge

This adventure is taken straight from the TAME competition archives to help your students prepare for our Divisional STEM Competitions.

The objective is to design and build a crane to deliver marbles to the top of the very tall Aggie stadium, Kyle Field. The objective is for each team to design a versatile crane that scores the most points based on several criteria: the height that the crane can lift a load, the ability of the crane to pivot on the vertical axis, and the maximum load it can lift. The team with the highest total number of points wins. If this were a real Divisional or State STEM Competition, awards would be given to teams that design the most innovative working models.

Supplies needed:

3 small boxes | tape |

3 paper cups | 2 marbles |

4 large paper clips | 2 rubber bands |

4 toothpicks | 1 clothespin |

1 pair of scissors | 4 large hex nuts |

8 feet of string | 3 sharpened pencils |

1 gallon zip bag | 2 pipe cleaners |
