The Smithsonian Science Education Center offers a selection of educational games for elementary school students. Bumper Ducks is one of those games that I recently tested.
Bumper Ducks is an online game in which students have to help rubber ducks navigate bodies of water to collect duck treats. To navigate the bodies of water students have to determine how hard to make a duck swim or fly and account for angles to avoid obstacles in the water.
Applications for Education
Bumper Ducks is not the most challenging game that elementary school students will play, but it could be a nice little activity for introducing or reviewing some basic geometry concepts.
