3/13/19: IEGTL - Climate Data Collection

Objective:  Locate credible data for the country you have chosen for your Climate Impact Project
 
1.  View tutorial on how to use NASA Data
 
2.  View tutorial on how to use GIS (Geographic Information Systems)
 
3. Create a data set that compares climate data from 2 DIFFERENT time periods.  Remember, climate is the study of LONG TERM AVERAGE WEATHER Conditions.  

3/12/19- IEGTL: Textbook Reading

1.  Read the rest of Chapter 21 in the Physical Geology Textbook.

3/11/19: Is Earth Getting Too Lit? - Evidence of A Changing Climate

1. Review Cosmos: Chalk Talk- Compare and Contrast Earth and Venus Climates
 
2. Reading: What data indicates our climate is changing like Venus once did?
 
3. Reading: Causes of Climate Change (Text Pg. 513-519) 
 
4.  Where's the Data?
 
Project Planning: Choose a global COUNTRY that you think has a unique climate based on some of the weather concepts we have discussed (location, water, etc.)
 
    Each person in the group will be responsible to research the climate change data for 1 INDICATOR (See #2 above)
 

3/8/19: Video - Cosmos

1. Watch the Cosmos Episode - "The World Set Free"
 
2. Write 1 Quote that summarizes the theme of the video per 5 Min.  
 
45 min./5  = 9 - 10 Quotes
 
We will discuss these quotes to introduce our next unit of study

3/6/19: A.P.C. Compressed Air

1.  Watch the video of the 10 PSI Air car at 3:10
 
Use the video and your project experience to estimate:
 
Car Mass, Distance, Time, Velocity, and Kinetic Energy
 
 
2.  Watch the video of the 50 PSI Air car at 2:10
 
Use the video and project experience to estimate:
 
Car Mass, Distance, Time, Velocity, and Kinetic Energy
 
 
3.  Chalk Talk: Draw a model of how compressed air works.  
 
4.  Write a summary: How does compressed air store and transfer energy different than regular air? 

3/1/19: APC - Air Powered Car Data #2

1.  Conduct 5 Trials with your Air Powered Car.  Collect data on the Mass (Kg), Forward Distance (m), Sideways Distance (m), Seconds traveled (s), Velocity    (V = D/T) and Kinetic Energy (KE = 1/2 M X V squared)
 
2.  ONLY ONE PERSON needs to upload your data into this form:
 
3.  Watch this video for one final idea on how to maximize your potential energy in the car
 
4.  ALL STUDENTS turn in a written summary with following sections.
    A.  How did you maximize the potential energy/air pressure in your car?
    B.  How did you build your car to ensure that your car used Newton's 3rd Law with the most efficiency?  (For every action, there is an equal and opposite reaction)
    C.  How did you minimize energy lost to friction in the wheels?  
    D.  What factors had the most affect on the success of your car?

2/26/19 - APC - Improving your Car

1.  Review/Discuss your Kinetic Energy Calculations
     A.  What data do you need to calculate the Kinetic Energy in a moving object?
     B.  What needs more kinetic energy: A running person or a running cheetah (m = 47 kg, v = 31 m/s)? Why? 
     C.  What needs more kinetic energy: a moving Polar bear (m = 500 kg, v = 11 m/s) or a moving person?  Why? 
     D.  Why is the KE value of your car so low? 
     E.  According to the equation KE = 1/2 M X V squared, which will affect the Kinetic energy more: adding mass or velocity?  Why?
 
2.  Discuss the EFFICIENCY of your car
     Do you get out what you put in?   
     Energy Out/Energy In
     A.  Do you think the Kinetic Energy you calculated equals the amount of potential energy you put into the balloon?  
     B.  What things are LIMITING the movement of your car?  
     C.  View the following simulation on friction.  Describe what happens when you move an object across another. 
 
In an open system, you will never get out everything you put in.  Energy will be lost to the environment until you stop. 
     
3.  How can you improve the potential energy going into your car?  Remember, increasing the speed of the car will have a bigger impact on the kinetic energy than the mass.  Discuss the following factors.  You will make 1 improvement to the energy going into your car.  There is no limit to the materials, but you must provide them.  
 
    A.  Air - Amount of air, # of balloons, size of balloons, direction of air, size of straw, length of straw, etc. 
    B.  Friction - wheel shape, wheel size, wheel smoothness, wheel spinning
    
 
 
           

2/25/19: APC - Kinetic Energy Calculations

Objectives:  
Calculate the VELOCITY of your moving car
Calculate the KINETIC ENERGY of your moving car
Understand the factors that cause an object to move
 
 
2. Find the VELOCITY of your car (if it didn't move, just make up realistic numbers).  Velocity = Distance (in meters) / Time (in seconds)
 
3.  Find the KINETIC ENERGY of your car 
 
KE = 1/2 X Mass (kg) X Velocity (meters/second) squared
 
4.  Complete the following practice problems
 
Velocity
 
Kinetic Energy

2/22/19: PLATO A.P.C. #3 - Kinetic Energy

1. Finish the agenda from yesterday (Build 1st car design, collect data, and post to form link)
 
2.  Spend 30 MINUTES!!! viewing and completing questions in the PLATO tutorial about Kinetic Energy.  We will be calculating the energy in your car next week based on the content in this lesson.  

2/21/19- A.P.C: Air Car Data

2/19/19: Air Powered Car - Introduction and Design

1.  Watch "The CD Hovercraft" 
  
     Draw a model of air pressure and motion
     Conclusion - How did it work?
     Explain how potential energy was stored in the hovercraft.
     Explain how the potential energy was transferred into kinetic energy. 
     Explain what forces the hovercraft had to "defeat" in order to move. 
 
2.  Brainstorm 
     3 Requirements 
          Must be powered by air
          Must move for a distance on table top/floor determined by trials
          Must "stay in its lane"  a width determined by trials
How will you build your Air Powered Car with household items?  
Background research
Each person draws a design model that shows how air will move the car
 
3.  Conclusion 
Which do you think will work the best?  Why? 
How are you maximizing potential energy and minimizing gravity/friction? 
Bring in materials for building tomorrow.
