Sally： 1 The machine is powered by the sun’s energy. It can not only find litter but also put litter into different groups.

Allen： I developed an app to recommend （推荐） songs. It records someone’s heart rate （心率） while listening to music. The information is then used to recommend other music that can help the person relax.

Allen： When people are listening to my music， they all have different feelings. So that’s where I got the idea to start this project.

◆What was your favourite part of this project？

Allen： My favourite part was finding out proper music. 3

◆Any advice for science project beginners？
