Developer: fishdog.net

This game-show-inspired Earth Day app is perfect for classrooms with a big screen, but also works for remote teaching or for individuals. In group games, players take turns matching vocabulary word tiles. A correct guess allows the same player to make another guess. Once the illustration is revealed, players take turns guessing letters to reveal the secret concept word or phrase. You can advance one by one through the 9 games, or tap a picker button to choose a particular puzzle. 

Topics in this app: pollution, biomes, energy, climate change, recycling.
