Science Testing heart rate.

We have been doing a little bit of science this term once a week. We do a rotation so each week we change the experiment.

For the first experiment was building a bridge, out of popsicle sticks, tape and paper, we only had limited items. First we had to search up strong bridges and, then we had to chose one how we would make it. We found out that the strongest bridges in the world were triangles one.

 We  did one about matter with an ice cube. So we had an ice cube floating in the water then when the ice cube melted to see if the water had risen.

 The third thing I did was testing out heart rate. I always wanted to know how you test your heart rate. I always wondered how people could tell there heart rate and they would always do some thing with there wrist, but I learned a different way. Yes that right you don't have to waste you time fiddling around with your wrist, because all you do is take to fingers and press them against your neck just under your jaw bone, it is really cool to hear your heart beat, if you can't find it maybe try a little higher. Count your heart beats while you have a ten seconds timer going on at the same time. When the timer has reached ten stop counting, then time your beats by 6, example, 6 times 12 = 72  and there's your answer.
