Mrs. McAfee's Digital Portfolio
7th Grade Math/Science
Week 1: Ring the Bell Challenge
Students were challenged to work as a team to design Rube Goldberg style machines with a series of interactions that would ring a bell. Each day the challenge was increased by added requirements, increasing the number of interactions in their design.
Students then discussed and developed norms for successful team work.
-
Step-up or step back
-
listen to group member's ideas and try them
-
Be kind and respectful to group members
-
Spend some time planning
Impractically Practical Perpetual Presentation Delivery Device Project
In this cross curricular project students will be looking at the essential question, “How have major discoveries and inventions in science and mathematics shaped our modern world?” Inspired by Rube Goldberg, we will be using modern technology, to design and fabricate a complex interconnected machine installation, which presents these major historical events in unique ways.
Week 2: Simple Machines
Students researched and reviewed the 6 simple machines:
-
lever
-
pulley
-
wheel and axle
-
inclined plane
-
screw
-
wedge
Students will be applying their understanding of how simple machines work to design their delivery devices.
Week 3: Mechanism Study
Studnets begin exploring the vast world of complex mechanisms, from the that produce unique types of motion:
-
linear
-
intermittent
-
oscillation
-
rotary
-
reciprocating
-
irregular
With a partner, students will research, design and make a specific type of mechanism and present their work to their group members and classmates.
