Scientific Investigations 3-4
Mia Bogovic , St Ambrose Catholic Primary School , Mould Growth on Bread
Mia investigated the effectiveness of cleaning products on hands and hard surfaces by examining the level of mould growth on bread after it has been rubbed with dirty hands or bin lids . The results showed that cleaning products do give some form of protection on both hands and hard surfaces , with soap and water giving the longest protection .
Thaddeus Candra , Redeemer Baptist School , Caffeine , Caffeine , How Do You Affect My Sleep ?
Thaddeus investigated if drinking caffeine before sleeping affects the different stages of sleep . With small amounts of caffeine intake , he found it improved deep sleep but reduced light and REM sleep . Overall , Thaddeus ’ s results showed that the more caffeine you have prior to going to bed the less sleep you have .
Joseph Hodgson , Redeemer Baptist School , Pacing The Playlist
Joseph investigated if people walk to the beat of the music when listening to music and if playing a song with faster beats per minute would increase the walker ’ s speed . He was surprised to find that the genre of music had no effect on walking speed , but the results showed that when people listened to faster songs , they did increase their walking speed .
