The Power of Produce: Powering Up with Fruits and Veggies!
An example of a completed solar cell.Copyright Ruben Ramirez
Students create solar cells using dyes extracted from fruits and vegetables to test how color affects the conversion of solar energy to electrical energy. They apply the engineering design process by asking questions and hypothesizing which fruit or vegetable will produce the most energy. After assembling their solar cells, students test the output using a multimeter to measure voltage. They then analyze their results and have the opportunity to redesign, rebuild, and retest their solar cells for improved performance.
A chemical engineer applies principles of chemistry, physics, biology, and mathematics to solve problems related to the production and use of chemicals and materials. They conduct research and development to create new materials and processes, as well as improve existing ones. Chemical engineers design manufacturing processes for large-scale production of items such as plastics, pharmaceuticals, and fuels, ensuring that these processes are safe and meet environmental regulations. Chemical engineers play a vital role in creating products that enhance our everyday lives while prioritizing safety and environmental sustainability.
After this activity, students should be able to:
- Describe how energy is converted and transferred.
- Apply scientific ideas and the engineering design process to design, test, and refine a solar cell.
- Understand that the earth’s renewable resources can be used in different ways.
