STEM challenge: build a flashlight. Students will love engineering their own flashlight out of a craft stick! Students will use their knowledge of circuit electricity, insulative and conductive materials to engineer a small flashlight. Students will identify the criteria and constraints and use design-thinking to build a flashlight.
This STEM Activity includes:
- Step by Step Directions with photos
- Reading passage on circuit electricity
- Follow-up pages
- CER Form
Students will use their knowledge of circuit electricity, insulative and conductive materials to build a small flashlight.
You will need simple materials:
- Craft sticks
- Copper tape or foil
- LED lights
- Coin batteries
- Metal binder clips
This resource meets the following standards:
NGSS MS-ETS1-1 Define the criteria and constraints of a design problem with sufficient precision to ensure a successful solution, taking into account relevant scientific principles and potential impacts on people and the natural environment that may limit possible solutions
NGSS MS-ETS1-2.Evaluate competing design solutions using a systematic process to determine how well they meet the criteria and constraints of the problem.
Analyze data from tests to determine similarities and differences among several design solutions to identify the best characteristics of each that can be combined into a new solution to better meet the criteria for success.
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.
