Steps:

A. Electrical energy is stored in the phone.

B. The electric energy becomes elastic energy as a rubber band is used to catapult the phone forward.

C. Elastic energy becomes chemical energy as it hits the car containing a battery.

D. As the car starts to roll down the inclined plane the chemical energy from the battery powered car becomes mechanical energy

E. The car hits a book causing it to fall on a lever transforming the mechanical energy in to gravitational energy.

F. The gravitational energy transforms into mechanical energy as the lever causes the wheels & axles (penny board) to start rolling forward.

G. As the penny board meets a set of books the mechanical energy becomes gravitational energy causing the books to fall.

H. The books hit the plane causing the ball to roll away transforming the gravitational energy into mechanical energy.

I. Lastly the mechanic energy from the ball rolling away becomes gravitational energy as it causes the carton to fall pouring water into the cup.

 

Energy Transfers:

  1. Electrical EnergyA -> Elastic EnergyB
  2. Elastic EnergyB -> Chemical EnergyC
  3. Chemical EnergyC -> Mechanical EnergyD
  4. Mechanical EnergyD -> Gravitational EnergyE
  5. Gravitational EnergyE -> Mechanical EnergyF
  6. Mechanical EnergyF -> Gravitational EnergyG
  7. Gravitational EnergyG -> Mechanical EnergyH
  8. Mechanical EnergyH -> Gravitational EnergyI

(Superscripts signify which step from above is producing the form of energy)

Types of Energy:

  1. Electrical Energy
  2. Elastic Energy
  3. Chemical Energy
  4. Mechanical Energy
  5. Gravitational Energy

Simple Machines:

  1. Inclined plane
  2. Lever
  3. Wheel & Axle

Data Visualization Infographic

Data Visualization Infographic

Data chosen:

https://public.tableau.com/profile/tina.norris#!/vizhome/FIGURE9_1/Dashboard9_1

I chose to represent this specific data as it permitted me to reflect on multiple ways to visualize it. I had ultimately decided to use my favourite idea in order to visualize the data presented. In my infographic I used 1 full glass of wine to demonstrate every 5% value of the amount of people who have participated in 1 heavy drinking day in the passed year. The visualization of this data allows us to visually understand the increase and decreases of this data over the years in a more visually appealing and creative way as to solely looking at a monotone bar graph.

Scientific Method & Paper Airplanes

Scientific Method & Paper Airplanes

We tested if the weight of a paper airplane had an effect on the distance in which it would travel.

We believed that the more weight added would allow the plane to fly further as a result of the lift of the plan becoming equal to it’s weight. Therefore resulting in a further distance traveled.

Some variables would come to play during the experiment as well including:

  1. The Dependent Variable: Distance Traveled
  2. The Independent Variable: The number of paperclips added
  3. The Controlled Variables: Shape of the plane, Height at which it is thrown at and the force used to throw the plane.

To come to this conclusion we decided to test three different weights on our paper airplane

  1. World Record Paper Airplane – with NO paperclips
  2. World Record Paper Airplane – with 2 paperclips
  3. World Record Paper Airplane – with 4 paperclips

We threw each airplane 5 times to get the most accurate result and so we could track the average distance.

Here are the results:

The plane with 2 paperclips had the highest average of 7.04 meters

The plane with 4 paperclips only ended up flying an average distance of 5.69 meters.

And lastly the paper airplane with no paperclips flew the shortest distance with an average distance of only 4.28 meters.

Unlike we had predicted the plane with 2 paperclips ended up flying further than the plane with the most weight by a difference of 1.35 meters, therefore rejecting our hypothesis.

This investigation enlightened us to how the placement and amount of weight has an effect on the distance a paper airplane is able to travel. Providing us us with the knowledge as to which weight is most suitable in order to get the plane to fly the farthest.

To improve this investigation it would be best to use a measuring tape that could stretch out to the distance the plane had flew as opposed to using a meter stick to measure the distance.By using a meter stick it would allow you to get more accurate and more precise results.
