My hypothesis was that I think that lots of electric energy will flow through the conductive dough, because electric charges are supposed to flow easily in anything that's conductive. The purpose of this experiment was to see how conductivity affects circuits and see conductive things in action.
In the experiment the voltage of the dough connected to the wire changed because of shape, size, and amount. The battery alone was 1.7 V. All of the dough was 362.4 gr and had a voltage of 1.1V. We divided the dough into three pieces each about 121 grams. One was a small roll which was 10cm. long that had 0.9V. Another was a long snake 82cm long and had a voltage of 0.5 V. The conductive dough did conduct. When we put the conductive dough in a circuit with resistors none of the resistors worked. This shows that our dough was conductive, but not conductive enough to be able to work a resistor.
In this experiment I found out that conductive dough can easily carry voltage and create an electric current. I also found out that resistance factors like length, size, shape, and amount can affect voltage too. For example the long snake had less voltage than the big glob of dough because the path was longer. My hypothesis was correct, the conductive dough carried electric charges easily.
When we did the experiment we took out all of the sugar (1/2 a cup). The battery voltage was 1.5 V. The dough all together had a 0.001 volts. We tried a donut shape with a diamater of 7.1cm width of 2.5cm.and was 75gr., a flat pancake shape that was 227.4gr. and had a diameter of 10.5cm., a cube that was 3.5cm. by 3.5cm. by 2cm. and was 36.5 gr., and made a triangle that was 14.cm by 14.5.cm by 13cm by 1.5 that was 227.3 gr. too. All of these shapes had a voltage of 0.001 V. This tells us that sugar did not affect the conductivity of the dough and maybe other materials were more insulating than the sugar and could have made a larger impact on the conductivity of the dough. This also explains why the conductivity was not large enough to make the resistors work.
There are many errors that could have took place that may have affected the results of any of the experiments...

The main idea of these experiments was to prove the difference between conductors and insulators. Conductors can easily have electric charges flow through them unlike conductors were electric currents can't flow through them.
My hypothesis was that if we take out sugar from insulating dough, than the dough would be more conductive, because sugar with water does not create electric charges. The purpose of this experiment was to see if sugar affects conductivity because in research found, sugar in a insulator.
The testable question was ... Will sugar affect the conductivity of the insulating dough.
Analysis: I have learned that insulators, are insulators and that energy and electric currents do not travel through these insulators easily. In the science books and other websites everything says that insulators are the bad ones for traveling energy, the currents just don’t really flow. Our dough had a voltage of 0.1 volts. Although it barley has voltage travel it doesn't have enough to work a resistor like a light bulb, In the long tube it was 46.8, but in a big glob 8.5. This didn't affect the voltage. This made me realize how true everything was and that electric currents can not travel through insulators. In order to believe some sources or not, first take sources that were provided by the school because those are trusted, than use sites like .gov, .org, and .edu because those are educational websites. Also see what the majority of the websites say if 10 websites say the same thing and 1 says something different, go with the 10 websites info.
Conclusion: If a electric current can travel through the insulating dough, than the insulating dough isn’t really insulating, because electric currents are not supposed to flow through insulators. My hypothesis was correct because are insulating dough was an insulator, very little energy could flow through it.
Insulator- something that charges can not flow through easily, electric charges do not transfer well.
My hypothesis was that if electric charges can barely flow through the dough, than the dough is an insulator, because insulators have no or very little electric currents. The purpose of this experiment is to see how insulators work in electric circucts.
Resistance- the measure of how difficult it is for charges to flow through a material.
Analysis: In our experiment we took out the sugar from the insulating dough because sugar is an insulator. This will enable us to see if sugar affects the conductivity of the dough. In our experiment the voltage was n different and actually a little less than the original insulating dough. This tells us that sugar does not affect conductivity in the dough and probably other factors/ingredients were more insulating than the sugar that could have made a bigger difference. The dough had a 0.001V with a battery of 1.5V. This proves that my hypothesis/prediction thinking that sugar will affect the conductivity were wrong, and that sugar is not a large factor in making the insulating dough conductive.
Conclusion: If sugar will affects the conductivity of the insulating dough, than the insulating dough will be more conductive, because sugar is an insulating. Because of the inquiry developer experiment I have learned that my hypothesis was incorrect. Although sugar is an insulator and maybe affected the insulating dough in measurements I could not see I have learned that other materials in the insulating dough were more insulating than the sugar, and could have made a larger impact. Although is probably the main reason why sugar did not affect the conductivity of the dough, many errors could have taken place. For example we kneaded our dough with a lot of flour, so that could have changes the results. Also, we forgot to clean some of the counter we worked on. All of these factors conclude that in my experiment, sugar did not affect the conductivity of the dough.
Voltage- the difference in electrical potentail energy between two places in a circuit.
Volts(V)-measurement of voltage.
My group made the dough into various shapes and sizes the insulating doughs voltage always ended up being 0.1 Volts (V) even though that battery itself was 1.5 V. Our dough was 262.1 gr. This proves that insulators do insulate. Even when we tried using resistors (motors/light bulbs) in the circuit to see if the dough carried enough electric charges to enable them to work, it was not enough electric charge to be able to use the resistors. This proved that are dough was insulating and was an insulator.
Circuit- A route that starts and finishes in the same place.
Dough- A thick substance of flour and a liquid often used to make bread and pastries.
Conductor- materials that charge can flow easily.
Conductivity- amount of charge that flows through an objects.
Resistance- the measure of how difficult it is for charges to flow through a material.
Resistor- a material that creates resistance/ also could be something that works when in a circuit like a motor or light bulb.
Electric Charge- the protons and electrons that travel through things
Electric Circuit- a complete unbroken path that electric charges can flow
Electric Current- continuous flow of electric charges through a material
I have figured out that sugar does not have a large impact on the conductivity of an object and that other materials play a larger part in conductivity in the insulating dough. The insulating dough did not become more conductive. No electric current was creates. This shows that my hypothesis was wrong, sugar does not play a large roll in conductivity.
