Slide 1: 

How can electric pulses affect your body?

Slide 2: 

The brain has billions of nerve cells, or neurons. Neurons combine to make the body’s Nervous System, thin cords that spread from head to toe. Neurons take in and send out electric signals, called impulses, that respond to everything your body does and feels. Then your brain turns this into your sense of touch, or feeling. I am testing to see what differences electricity can make in our nervous system. I am wondering if the electricity can disrupt the electric signals emitted from the neurons. The Nervous System

Slide 3: 

Electricity Electricity is the flow of electric power or charge. This can be created in many different ways, but right now we are just focusing on a turbine generator (like the one I have here). A turbine generator is a device that converts mechanical energy into electric energy. In turbine generators the electricity is made when an electromagnet (which is a magnet powered by electricity) is spun around a coil of wire. This movement electrifies the wire. Then the electricity is pushed away through special transmitters.

Slide 4: 

Tests... I am trying to see what differences will occur in my body due to electric pulses. I will test this by receiving electric currents from a hand-crank generator (somebody else will crank it). Then I will test these three things to identify the dissimilarities between my body regularly and with electric pulses. I will test my friend (Ben) too: We will be submitted to electric pulses for 30 seconds, then test our heart rate for a minute afterwards. We will see what changes occur. We will read for a minute regularly and read for a minute while being exposed to electric pulses, and compare the difference between the amount of words read. We will do the most-push ups we can regularly, then compare this number with the amount of push-ups that we are able to do while holding on to the working generator.

Slide 5: 

Hypothesis... I predict that Test 1 (heart rate) will come out positive. I think that our heart rate will increase by about 30 beats per minute (BPM) for each of us. I predict that Test 2 (reading) will not be affected. I do not think that the electric pulses will affect our concentration. I predict that test three (push-ups) will turn out to be negative. I highly doubt that our strength will be affected by electricity.

TEST Results

Slide 7: 

This test did come out positive. My heart rate increased by 20 BPM and B increased by 30 BPM.

Slide 8: 

I was surprised to find that this test too, came out positive as well. My words per minute increased by about 80, and B’s increased by about 60.

Slide 9: 

I do not think that this test came out positive. Unless you count the difference of 4 push ups in my tests, there isn’t much difference. Personally, I believe that there is not enough evidence to support that electricity affects your strength, but it’s in you’re point of view.
