使用BBC micro：bit 在BLOODHOUND火箭車比賽中
一架車能走多快？ 你家人的汽車速度大概不會超過 70 英里（110 公里）每小時，但這裡有一群工程師，目標是創造出能時速達 1000 英里 （1600 公里）！
「尋血獵犬計劃」的一群工程師希望達成這個目標，並且幫助全英國的學童也親身體驗這種超級速度，就是用 你的 BBC micro:bit。
與微軟教育和英國陸軍密切合作，線上火箭車比賽將推廣到全英國 4000 所學校，參與學生達 112,000 人。
The “Race for the Line” BBC micro:bit Model Rocket Car Competition will encourage pupils aged 11 to 16 to work together to make a foam rocket car powered by a small solid fuel rocket motor, and pit it against rival teams.
Teams compete at open race days at one of 120 regional Race HUBs. The top two primary and secondary school teams from each hub will qualify for the regional finals in March 2017. The winning primary and secondary school teams at each of the 15 regional finals are invited to the national finals held in June at the Santa Pod Raceway, Northamptonshire.
To prove just how fast your car is travelling, the BBC micro:bit can be used to capture data on your car's speed, then upload it to a computer.
Use that data to tweak and experiment with your car design and you may have a champion machine in the making!
Participating teams will learn about Newton’s 3rd law of motion, physics, engineering, chassis design, how rockets work, teamwork, time keeping and most crucially, mathematics to calculate the speed attained.
Schools and youth groups can visit BLOODHOUND’s social learning site to find out how to enter by visiting www.racefortheline.com and must register by 31st October to receive their free rocket car kits.You can also view and download the BLOODHOUND contest flyer .pdf here.
