In this project, students will assemble a small motor and solar cell with reused materials to create a wobble bot.
This is a hands-on project that will help students problem-solve and innovate.
The materials required for this project should be available without purchasing new items. However, you may need to ask students if their parents or guardians have any of the materials available to borrow.
Maker spaces may also have some materials to borrow and thrift stores or ReStores may have items as well.
Students could experiment with other materials and light sources or different colored lights to see if it changes the activity of the bot.
Solar rechargeable batteries (powered by the sun) could also be used to demonstrate the ability to store solar energy when the sun isn't shining.
This resource provides instructions for the construction of a fun and simple "Wobble Bot" which uses solar energy (harnessed through a recycled solar light) and reused materials. While this activity requires the use of hot glue and wires, it is well-described and provides some troubleshooting tips. This resource is recommended for teaching.
