POE - Lesson 1.3 Videos

1.3.1 Hydrogen Fuel Cells
This is a longer video, so plan to take notes on these ideas: How is energy produced from hydrogen? Specifically, how do membranes in fuel cells help generate electric current? Where do we get Hydrogen from? Is Hydrogen energy safe? What are the challenges hydrogen car technology has to face? How does solar energy relate to hydrogen energy? |
|
1.3.1 Hydrogen Fuel Cells
An overview of how hydrogen fuel cells work, and some of the reasons why we use fuel cell systems. 1. How efficient can fuel cells be compared to traditional power sources? 2. What are some of the applications for hydrogen fuel cells? |
|
1.3.1 (Day 2) High Speed Hydrogen Cars
The hydrogen VEX cars might not be that fast, but take a look at car companies are able to do with Hydrogen. - Was this built to break records or demonstrate what could be brought to market? - What speed record did the Hydrogen 999 set? |
|
2.1.0 Career Field Descriptions
As part of the year long research project, the second step is to look at different employers, and while you probably have a few companies in your mind, this is a quick overview of engineering companies that were featured on the Forbe's 2013 List of Dream Employers for Engineering Students. |

Lesson 1.3.3 - Misconceptions about Tempreture
What is hotter? Metal or Paper? Which is cooler? As you are watching this video make some notes about how temperature and materials relate. |
|
Lesson 1.3.3 - The Zeroth Law of Thermodynamics
More than just reviewing the Zeroth Law of Thermodynamics, this video explores a few other ideas.In your notebooks, write down What does the zeroth law allow us to do scientifically? What tools allow us to observe temperature in the environment? What is thermal shock? How do digital thermometers measure temperature? |
|
Lesson 1.3.4 Recycled Insulation
Our on-going project this week is about Renewable Insulation. Watch this video on how they use recycled soda bottles to insulate their home. What makes a material a good insulator? What other materials do you think they could use? |
|
1.3.3 Heat radiation and Stefan's Law
More of a visual idea than calculations, pay attention to how much time it takes to heat the metal rod and it gains visible color and light compared to how quickly it looses the heats appearance in the visual spectrum disappears |
|
Lesson 1.3.3 1st Law of Thermodynamics
In this video a student demonstrates the 1st law of thermodynamics. Watch the video closely and describe what you think is happening. What would you have done differently? |
|
Lesson 1.3.3 - Transfer of Thermal Energy
Take a few minutes to review different types of thermal energy transfer. Take notes on each of the three types of transfer discussed in the video |
|
Lesson 1.3.3 - Heat transfer from metal to water
This problem is similar to our metal placed in water problems. Note that the units they use for heat capacity are a little different than what we have used, but that these differences are the same as any metric unit conversions we have done before. |
|
Lesson 1.3.3 - Stefan's Law
The last thermoelectric equation we are going to look at in this lesson is Stefans Law, and making calculations for thermal radiation. While this video goes quickly, not what values and unit conversions are needed for these problems, and what constants are given. |
|
Unit 1.3 Heat Transfer Review
Crash course won't go into all of the mathematics of heat energy transfer, but goes into good detail of convention, conduction, and radiation energy transfer, and will expand on what we looked at with thermal conductivity in insulating materials. |
|
Unit 1.3 Review
Take a minute and review some of the electrical conepts from 1.2 and 1.3. Ohms law and Kirchhoff Law are both practical equations from your hydrogen / solar powered car project |
