About this app

Energy Efficiency is an interactive science learning app for exploring how input energy is divided into useful output and wasted heat. Tap examples such as incandescent bulbs, LEDs, kettles, fans, cars, solar cells, and running to compare approximate efficiency values. A bulb-switching calculator and quiz help learners connect efficiency with energy-saving choices and purpose.

Use cases

  • Elementary students learning about energy transformations
  • Teachers introducing energy efficiency in science class
  • Learners comparing incandescent, fluorescent, and LED bulbs
  • Families exploring how lighting choices affect monthly electricity use

Features

  • Interactive energy-flow comparisons for nine devices and activities
  • Approximate efficiency percentages with useful and wasted energy forms
  • Monthly bulb electricity calculator with adjustable bulb count and daily hours
  • Same-brightness comparison between incandescent, fluorescent, and LED bulbs
  • Quiz on efficiency calculations, comparisons, energy waste, and purpose
  • Guided challenges for completing activities and tracking correct answers
