Sadly, Dr. E’s WeDo Challenges and Dr. E’s MINDSTORMS Challenges will no longer be posting new challenges. However, both websites will remain up so that you can continue to access the previous challenges and all of the wonderful submissions. Thank you to LEGO Education and to the Center for Engineering Education and Outreach at Tufts University for their years of support (and thank you to LEGO for their amazing robotics platforms). During the six years of WeDo challlenges and five years of MINDSTORMS challenges, we received almost 1000 submissions from around the world. The two websites had a total of 1266 registered users from 57 different countries. We were truly a global community! We have always been inspired and energized by the creativity and innovation shown by the Dr. E's Challenges community; while new challenges won't be posted moving forward, we hope that you continue doing awesome stuff in your homes, clubs, and classrooms and that you continue to share your projects with the world! Collaborating with all of you has been a joy and an inspiration. Thank you, The folks at Dr. E’s

A Beautiful Thing


Our Proverb is:  A Beautiful Thing is Never Perfect. Our proverb means no matter how beautiful something may seem, it always has a flaw.  We showed that by representing a bee and a flower.  The flower and bee represent something that is very beautiful yet the bee stings and flowers often have thorns.  Our program turns the axel which causes the bee to fly over the flower. The flower contains a motion sensor and when the bee crosses the path of the motion sensor you hear a buzzing sound.

    Great project! We love how you used a motion sensor and the sound effects. Your written description was very well done and it really made us think. Your flower and bee were spot on and looked like a real masterpiece Great job! 🙂
