I. Title – The Effect of Volume on Heart Rate II. Problem/Research question – Your heart rate can be affected and changed using a variety of things. One thing that can cause your heart rate to change is the volume of audio. How does the volume of an audio track affect your heart rate? If the volume of an audio track is increased‚ the number of hearts beats per minute will increase as well. III. Variables – ❖ Independent Variable ➢ The volume of the audio track ❖ Dependent

exercise on heart rate/ breathing rate? Justification Pulse is an ongoing wave of pressure in the arteries‚ caused by pumping of heart. Pulse can be measured on the wrist‚ neck‚ back of the knee or any other pulse point where arteries run close to the surface of the skin and compress on the bone. Pulse rates vary from person to person. Your pulse is lower when you rest and increases when you exercise. More oxygen rich blood is needed by the body when exercising so knowing how to take your pulse

differently‚ specifically a person’s heart rate and blood pressure. After exercising your heart rate should increase and your blood pressure should decrease (Blood Pressure Association‚ 2008). The purpose of this lab was to determine which level of exercise would have the greatest impact on affected pulse and blood pressure. In this lab we tested how exercise affected heart rate by testing a random group of people with different body types and exercise levels to see how different types of exercise would affect

The purpose of the experiment conducted was to observe if a higher concentration or lower concentration gradient would affect the diffusion rate of the iodine moving through the starch concentration. This was shown to be an accurate experiment as with a higher concentration gradient the diffusion that did occur happened a lot faster and diffused more efficiently compared to no iodine solution and just water. This is due to the molecular collisions speeding up the experiment in the time period given

Biology Investigation Problem: How does light affect the rate of Photosynthesis? The Plan In my experiment I am going to see how light affects the rate of photosynthesis. To do this experiment I am going to set up the apparatus as shown in figure 1. The apparatus I am going to use are the following: - 1 Tripod 1 300ml Beaker 1 Boiling Tube 1 Clamp Stand 1Clamp 1 Boss 1 Ring Binder 1 Lamp 1 1 Metre Ruler 1 Thermometer 1 Stop Clock To do the experiment I will set up the apparatus first.

results a final conclusion can be drawn. The hypothesis was supported by graph 3 and 6 which both showed that an increase in concentration of the reacting species resulted in an increase in reaction rate. Both graphs have a positive gradient which clearly indicates that concentration increases the reaction rate. The hypothesis also proposed that as temperature increases the speed of the reaction would decrease‚ this is evidenced in graph 7 which shows a negative decrease in time as the temperature of the

solutes (iodine + H2O) than did the starch solution. So iodine move into the cell and react with starch molecules to formed starchiodine‚ the blue compound‚ with a specific rate. The test show that mean rates of diffusion are significantly different acording to the concentration. So the concentration have an impact on the rate of diffusion. Also‚ the difference between the concentration in each compartment‚ concentration gradient. We see in the Fick law that if you modulate C1-C2 you will have

A reaction is a chemical process in which substances decomposes‚ or combines with other substances. In this case it is synthesis chemical process which creates new products. However‚ the rate of a reaction can be altered either faster or slower depending on certain variables. These variables are concentration‚ temperature‚ surface area‚ and catalysts. A reaction can be made faster or slower with a variation in the concentration of reactants; a reaction goes faster when there is an increase in concentration

Heart rate is an extremely important part of many people’s lives. It affects our personal health and how our body works. When the body exercises‚ the heart rate goes up and when the body is inactive or not being active the heart rate goes down. When the pulse is pumping fast‚ then that means work is being done. Having a high heart rate is good for the heart and the body. Obese people can use heart rate and exercise to change their life. Due to the amount of people that are obese‚ a good amount of
