One of the buzzwords at FETC was STEM which stands for Science, Technology, Engineering and Math. These of course are the subjects kids need to learn if they want be employed in years to come. We've done a good job highlighting math apps and have had several recent reviews this month of new number cruncher apps but science and tech apps are harder to come by especially free ones. These are some of my favorites from past Good Free App of the Day posts and some I've come across through my travels in AppLand.
Biobots Under Sea Rescue helps children learn about some of our planet's most effective underwater animals, design a robot which mimics some of those animals' most successful features and guide that robot on a rescue mission.
Brought to the iPad by Iridescent, a non-profit that encourages scientific learning and Night & Day Studios, this app is a great one for older children to explore the different ways that animals have adapted for success.
