Junkbots are easy-to-build robots that you can make using a simple circuit and some recyclable materials. In this lesson, your students will learn about engineering design as they compete to build the fastest robot. No previous robotics experience is required!
MS-ETS1-4. Develop a model to generate data for iterative testing and modification of a proposed object, tool, or process such that an optimal design can be achieved.
This lesson focuses on these aspects of NGSS Three Dimensional Learning:
Science & Engineering Practices
Disciplinary Core Ideas
Crosscutting Concepts
Engaging in Argument from Evidence. Evaluate competing design solutions based on jointly developed and agreed-upon design criteria.
ETS1.B: Developing Possible Solutions. A solution needs to be tested, and then modified on the basis of the test results, in order to improve it.
Cause and Effect. Cause and effect relationships may be used to predict phenomena in natural or designed systems.
Structure and Function. Structures can be designed to serve particular functions by taking into account properties of different materials, and how materials can be shaped and used.
For each student or small group of students building a robot, you will need these items from the
Bristlebot Kit
(also available as a
Classroom Kit
specially priced for teachers):
Motor (1)
AA batteries (2)
Battery pack (1)
Note: Kits are sold through our partner Jameco Electronics. Each kit contains
enough parts for two Junkbots, as well as parts for two
Vibrobots.
