Our question is how do targeted auditory cues such as water, presented during deep sleep lead to stronger memory retention? We wanted to see if hearing sounds like water at night help our brains remember things better during the day.

For this project we have made a model that shows that we first make memories during the day and as we make memories we can hear the sounds of water around us. When we then go to sleep our brains replays the water sounds, they are calming so that they don't wake us up, and the memories that we made during the day are strengthened and switched from short term to long term memories.

We researched about how auditory cues such as water presented during deep sleep leads to stronger memory retention. We researched about illness/diseases that effect our memory retention (we talked about Alzheimer's and Vascular Dementia), and a few of the stages of sleep that are connected to this topic. We also researched about what these terms mean and about the forgetting curve effect. We also included the parts of the brain that are connected to this process.

The data we gathered from what we researched is that water sounds do help with memory retention. Water sounds played at any time during the day are often replayed during deep sleep, and the memories connected to the water sounds are stored for long term shortage. Because of this we can recall our memories or any information later on in our life or a few days later.

In this presentation, we have talked about how targeted auditory cues, such as the sound of water presented during deep sleep, can significantly enhance memory retention by reinforcing recently learned information. During deep sleep, the brain naturally strengthens memories, and these cues subtly guide this process without waking the sleeper. These sounds encourage the brain to review and stabilize new information, helping short-term memories become long-term ones and showing how strategically timed cues can improve learning and memory durability.

We would like to acknowledge each other for working well as a team and sharing the work equally throughout this project. By cooperating and helping one another, we were able to successfully complete our science fair project. We would also like to thank our science teacher, Ms. Malhi, for helping us choose our topic and for guiding us whenever we needed help and Mrs. Sharma. Finally, we would like to thank our parents for their support and encouragement throughout the project.
