NGSS Standard for Kindergarten: Use observations to describe patterns of what plants and animals need to survive. Organization for Matter and Energy Flow. We are going to talk about how we need exercise to help keep us healthy. Next week we are going to talk about how we need healthy food to keep us healthy, and our teeth healthy.
Students will conduct an experiment to determine what is the best means of exercise to increase our heart rates.
Students will test out their heart rates with the following activities: dancing, running, jumping rope, and yoga.
Students will construct and create stethoscopes to use during their experiment.
Students will use real stethoscopes to listen to their heart beats during their experiment.
Engineering of Stethoscopes:
Students will create their own stethoscopes out of the following materials:
- Paper towel tube
- duct tape
- Plastic craft funnel I purchased these on Amazon.
|Draw 1 1/2 inch lines around the tube.|
|Cut the lines|
|Fan the tube over the tunnel. I cut off that little nubbin to help with taping|
|Start to wrap the tub with tape around the funnel.|
|What it should look like when it is finished.|
Now on to the experiment
I will be using my science lab report poster that I created. I have created these science posters that you can print off with a plotter.
Problem: We know that exercise is great for our heart, but which of the following exercise will increase our heart rates the most.
Hypothesis: The students will write down their hypothesis to answer what they think will increase their heart rates the most. The four exercises we will be testing are - jumping rope, yoga, dancing, and running. The students will record their hypothesis on these tickets. On the reverse is the conclusion that we will fill out later.
Procedure: We will spend 5 minutes on each exercise. After each exercise we will use our stethoscopes to listen to each others hearts. We will also use real stethoscopes to listen to each others hearts. The students will record their heart rates on the following recording sheet. The first step to to have the students lay down, or rest their heads on their desks for 5-10 minutes. Tell your students that this is your resting heart rate and this will be the lowest on our recording sheet. We will compare what we think the speed of our heart is to our resting heart rate.
Observations: We will record our observations during each activity.
Conclusion: We will take our hypothesis papers and on the back and fill out the conclusion. We will determine which activity got their heart rates up the fastest.
I will update this post after completion of the experiment!
