This lab experiment investigates the effect of listening to different types of music on one’s pulse. The experiment relates the circulatory system to the pulse as it measures how quickly the heart contracts and releases blood. Pulse is measured in beats per minute (bpm). One’s pulse is loudest near the heart‚ because there is more pressure closer to the heart. In contrast‚ one’s pulse is quieter the further away it is measured from the heart‚ because there is less pressure the further the distance

M1 – Differentiate between those questions that science is currently addressing‚ those that science cannot yet answer and those that science will never be able to answer. There’s many questions that scientist are currently addressing and many they will never be able to answer because of individual opinions and no evidence between any of the answers clearly because you can’t experiment any of it. For example in our modern day society there’s always debates on whether there’s a God or not? Around

ADI Lab Report Every living thing is made up of cells. All cells have some part in common. Some multicellular cells are highly specialized and carry out some very important functions. One of the special cells are red blood cells‚ their functions‚ transporting oxygen from the lungs to the cells in the body. Red blood cells look like little discs. Red blood cells can change their shape‚ this ability allowing them to squeeze through capillaries without breaking. Our task is to Design and carry out an

Introduction By examining blood smear by microscopy it can detect infections whether they are viral or bacterial. Blood smears are examined by looking at the white and red blood cells appearances. The aim of the experiment is to compare a normal blood smear and its pathological features to those with an infection or abnormality by the use of microscopy looking at the cells involved with blood. A normal blood smear would contain 3 to 4 white blood cells per field in microscopy. If there is an

The lesson is divided into 3 labs that can be completed in any order. After labs have been completed‚ facilitate a class discussion where students summarize and compare findings and relate how their findings support (or refute) Newton’s Laws of Motion LAB 1: How fast can it go? Put one car at the top of the ramp and let it roll down. Use a stopwatch to record the time the car rolled. Use this information to calculate the acceleration of the car.

Bio Lab Report Erica Patterson September 10‚2013 Intro to cellular and molecular Biology Lab Abstract: In the Biology Laboratory Manual by Darrell S. Vodopich and Randy Moore are results to a similar experiment. The studied the hypothesis of carbon dioxide production by yeast fed sugar is not significantly different than the carbon dioxide production by the yeast fed in protein. Their hypothesis is the one that has helped formulate ours. We also will be answering the same to questions “What
