Science Fair Project On Heart Rate
A Racing Heart: A Science Fair Project that Discovers Who has the Fastest Heart Rate
This science fair project is great for middle school students between the grades of six and eight. Most middle school students at one time or another have to do a science fair project in their science class. This is an easy project to do, involving help from your classmates. You are going to answer the question of who has the faster resting heart rate – boys or girls.

You don't need any special equipment for this project except for a stopwatch, two chairs and a notebook to record all of your findings in. You are going to ask students in your class to allow you to take their resting heart rate. There are several ways to determine a resting heart rate: you can either take it in their wrist or in their neck. The most accurate place to count how many heartbeats per minute is in the neck.
Before you start the project, you are going to need two things: permission slips, and a hypothesis. The hypothesis is what you believe is going to happen, and what you think the results are going to be. So, do you think the girls’ resting heart rate is going to be faster, the boys’ resting heart rate is going to be faster, or do you think that there is going to be no difference? For projects including people, you are probably going to have to get them to sign a release. If you are not sure about this, ask your science teacher to help you. This release says that you are not going to harm them and that the science fair project is not going to have any lasting effect on them.

Because you want to measure the resting heart rate of students, you are going to want to make sure that you wait until a good time. Don't try to do this experiment after recess or after gym class, because you're going to find that the heart rates of the subjects are faster than normal. To perform the experiment, make each student sit down in the chair, and then count the number of beats for a whole minute. Record the results after each student.
The more students you have in your study, the better the results will be. You should probably try to get at least 25 girls and 25 boys to take part in the study, to get accurate results. When you're finished, make an average of the number of beats per minute with boys and girls and compare the two numbers. What did you find out? Was your hypothesis right? If you did the experiment correctly, you should find out that girls do have faster rates than boys. To show off your data, make a couple of graphs that can show your results easily to the science fair judges.
Science Fair Projects MADE EASY!
Does your child have to do a science fair project soon?
Would you like to give your child some guidance, to make it easier for your child?
You have probably spend quite a while surfing the net for ideas. In spite of the time you’ve spent, you might still be wondering if you have all the necessary information to really help your child.
Here's a checklist to help you find out what all the details are that are involved in a science project:
- Do you know how science fair judges grade projects? Do you know what they look out for?
- Do you know what the rulesare for displaying a project?
- Do you know if it necessary to perform an experiment? (Can you do a project without an experiment?)
- Do you know how many different types of science projects there are?
- Do you know about the many different possibilities. Do you know a systematic way to go about choosing a topic?
- Do you know the differance scientific "Theory" and a "Hypothesis"?
- Do you know what your child can do if an experiment goes wrong?
If you can confidently answer all the questions above, you know all you need to know to provide your child with sound guidance.
If you are unsure about some of the questions, I can offer you a e-book that provides clear and relevant guidelines.
