Energy comes in many forms
Energy is the ability to do work, and this puzzle gathers its many types. You'll be finding the forms it takes — KINETIC energy of movement, POTENTIAL energy stored up, plus THERMAL, ELECTRIC and CHEMICAL energy — and the units we measure it in, the JOULE and the WATT.
Because every new puzzle reshuffles the grid, no two energy word searches are the same. One round a backwards GEOTHERMAL hides in a corner; the next a diagonal RENEWABLE appears across the middle.
Powering the planet
Where does our power come from? The sources are here. There's the RENEWABLE kind — SOLAR from SUNLIGHT on a PANEL, WIND spinning a TURBINE, HYDRO from water, GEOTHERMAL from the Earth, and BIOMASS from plants — and the FOSSIL FUEL and NUCLEAR sources too. It all adds up to the POWER and OUTPUT that runs our world, with HEAT and FUEL along the way.
It's a great fit for a science topic on energy and the environment. Tracking down G-E-O-T-H-E-R-M-A-L turns spelling practice into a power lesson.
How to play
Drag across a word, or click its first and last letter — both work. Each word you spot locks in with its own colour and ticks off the list, so you always know what's left to find.
