Our Project
For this project we took our knowledge from other activities and put them to the test to see if we were able to produce an energy source and circuit to power something. From our knowledge of circuits and energy transfers, we were able to do this. We began brainstorming ideas of what we should power and what we wanted to power it with. After much discussion we came to the conclusion that we should try and power a wind turbine ,or something small like that, using energy drinks.
After we decided to use energy drinks we started planning out how to use the electrolytes in energy drinks to power something even an LED. Using a similar method for a lemon battery we put strips of copper and zinc into the solutions to create a circuit. At first wer had only tried this with five beakers, only filled with monster. We soon realized we needed more power within the circuit, so we gathered other types of energy drinks, more beakers, and created a larger circuit. For this project we thought it would interesting to see what kind of energy is in energy drinks, rather than just energizing humans, what else can they power.
Continueing to add more and more beakers to the circuit we finally measured the voltage, 1.997 volts. From here we decided to think about what this amount of solution could power. Or if we could double, even triple, the amount of beakers and solutions. Creating a larger circuit and higher voltage. Theoretically, adding more and more beakers would give more and more electricity and the ability to power more and more things.

Background:
Background:
The background we did for this project and unit mainly constited of us understanding how energy transfers work and how circuits work. For this we had used the PHET simulation to show the different types of energy and how they move from one type to another. Using the lemon battery lab we were able to see how zinc, copper, and the citric acid in a lemon, could power an LED.

Content:
Sound Energy: Sound energy is the movement of energy through a substance – such as air or water – in the form of waves. It is produced when a force causes an object or substance to vibrate.
Elastic Energy: Elastic energy is stored in the bonds between the atoms in an object or substance. These bonds absorb energy as they are stressed, and release that energy as they relax.
In Elastic Energy: An inelastic collision is a collision in which there is a loss of kinetic energy.
Thermal Energy: Thermal energy refers to the energy contained within a system that is responsible for its temperature.
Chemical Energy: Chemical energy is the energy of chemical substances that is released when they undergo a chemical reaction and transform into other substances.
Mechanical Energy: The energy acquired by the objects upon which work is done is known as mechanical energy. Mechanical energy is the energy that is possessed by an object due to its motion or due to its position.
Nuclear Energy: nuclear energy, also called atomic energy, energy that is released in significant amounts in processes that affect atomic nuclei, the dense cores of atoms.
Gravitational Energy: Gravitational potential energy is the energy stored in an object as the result of its vertical position or height.
Electromagentic Energy: Electromagnetic radiation consists of two perpendicular waves, one electric and one magnetic, propagating at the speed of light.
Potential Energy: Potential energy in the realm of chemistry is in the form of chemical potential energy. This is energy stored in molecular bonds, which is the basis of chemistry and chemical reactions. Stored potential energy is released through these chemical reactions.
Kinetic Energy: Kinetic energy is a form of energy that an object or a particle has by reason of its motion.
Kinetic Molecular Theory: 1. molecules are always moving 2. volume is negligible 3. as well as the intermolecular forces 4. they undergo perfectly elastic collisions and 5. the average KE is proportional to the temperature.
ThermoChemistry: the study of energy transfer as heat that goes along with a chemical reaction and physical changes.
Calorimeter: a machine that measures the energy in a chemical or physical change.
Specific Heat: The heat energy needed to raise the temperature of 1 gram of a substance by 1 degree.
Enthalpy Reaction: quantity of energy transferred as heat.
Enthalpy Change: amount of energy absorbed by a system as heat during a process at constant pressure.
Endothermic Reaction: An endothermic process is any process with an increase in the enthalpy H of the system.
Exothermic Reaction: An exothermic reaction is a "reaction for which the overall standard enthalpy change ΔH⚬ is negative." Exothermic reactions usually release heat and entail the replacement of weak bonds with stronger ones.
Q = M C T: Q (heat energy in Joules) = M (mass in grams) x C (specific heat units) x T (change in temperature).
