Welcome to TVO’s mPower! In this video, we are highlighting one of our creative online Grade 3 STEM Design Challenges, Lazy River.


In this game, players design a lazy river ride and apply their knowledge of forces that cause movement to control the speed and direction of tube riders.


Players apply knowledge of transformational geometry to rotate a variety of river segments as they experiment with forces that cause movement to build their river circuit


Players use propulsion, wind and gravity to add speed boosts and control the speed and directions of riders. Caution! Fast moving tubes, especially around corners, may crash.


Using a variety of speed boosts and river pieces means happier riders and a higher score!


When their design is finished, players apply patterning skills to set the number of inner tubes they want to launch. In this example, the player must send a total of 30 riders down the lazy river. Each tube will hold six riders. Players use a strategy to figure out how many tubes to launch.


Players simply tap the arrow to test their designs at any time.


Once  the player designs a successful circuit, they are invited to give their lazy river a title and to reflect on what they learned, their challenges or what they would do differently next time. From My Gallery, players can then share their lazy river with their peers in the Class Gallery



From My Gallery, players can decide which designs they want to share in the Class Gallery.  Here, players can provide feedback to each other by selecting from a set of emoticons.


At the end of the game, players are presented with the STEM Maker Challenge, In Full Force! Here they are challenged to design and build a device that uses force to create controlled movement from one point or place to another. This offers an opportunity for players to apply problem solving, creativity, and innovation to a hands on challenge!  They then can share a picture of their engineering in the Community Gallery and receive  feedback from peers.


By the end of the game, students should be able to:

  • apply knowledge of transformational geometry, patterning and algebra when designing a river circuit; and
  • demonstrate an understanding of forces that cause movement.
