### Ali lab report

1. 1. Name: Ali Partners: Shi Hyun, Nathan and Song Lee Date of experiment: write the date here Running Effecting Heart Rateshouldn’t we be looking at Aim: The purpose of this experiment is to count how many times are heart beat in aother things that cause the heart minute.rate to change? increas ordecrease? Hypothesis: The heart will beat more after running because running requires lots ofit will beat more after runningthan? YOu need to be very oxygen and blood to carry the oxygen very fast. So heart will beat faster.speciﬁc. Variables:you HAVE to change Independent variable: In this experiment, we will not be changing anythingsomething for there to be an because we are not testing different material and ways ofexperiment. experimenting.you haven’t said what the Dependent variable: By putting two fingers in either your neck and wrist. Alsovariable is or the units that it will use stop watch to measure time.be measured in Control variables:speed of what? How will you Control variable 1: Speed -I will keep it the same by going the samemake sure that you go the same speed every time.speed? Control variable 2: Same person- I will keep it the same by making the same person go every time. Control variable 3: Distance - I will keep it the same by going one lap every time. Materials: • Stop watch • Two people (proper shoes and clothes) • A track
2. 2. Method: 1. Set up equipment. 2. Check normal rate of heartbeathow will you check this? Howmany times? Units? 3. Run one lap with enough speed that you will not exhaust or feel too slow 4. After finish running start the stop watch and count how many times you heart beat in a minute. 5. Record the data 6. Check heartbeat rate again 7. Wait until your heart rate recoverswhat do you mean, recovers?Be speciﬁc 8. Repeat step 3-5 three timesthen what? Results: Running Effecting heartbeat In A Minute Data TableUnits? Labels?

3. 3. Running Effecting Heartbeat In A Minute Graph Ali Shi Hyun 140.0 132.5Units, labels, title that says 125.0what is in the graph? 117.5 110.0 Trial 1 Trial 2 Trial 3 Conclusion: From this experiment, my hypothesis was correct which was “The heart will beat more after running because running requires lots of oxygen and blood to carry the oxygen very fast. So heart will beat faster”. The heart did beat more after running then before without having to run. The only only relationship would be that in the dependent variable, it was the right way to measure it with two fingers either in neck or wrist because it’s where we can feel the heart beat. I think our data is reliable because at first we didn’t get a reliable data but went to redo it to get to reliable enough. I think that it was hard to measure the heart beat because sometimes you will not be so sure about it. Evaluation: I think that the whole experiment work well in general because it was prepared and it wasn’t a difficult experiment to do except for the running part. One part in the method that went really well was going waiting for the heartbeat to recover because it only requires us to rest. I wouldn’t change anything in the method because I think that it was well done and it was a simple experiment so it wouldn’t have parts that were bad or need to be changed. I think that next time that there would be something that we were changing in the experiment because we had nothing to change.
