Navajo Bridges - New Mexico

Learning Targets:

1. I judge the effects of different types of forces & loads on a bridge
2. I build background knowledge about bridge design

Links:

• Balsa Bridge Building Contest – lots of information about building balsa bridges.  Our bridge building contest rules come from this site.
• PBS Building Big: Bridge Forces Lab – interactive “labs about the different types of forces & loads that affect a bridge
  

  Butterfly Bridge - Bedford, England

• HowStuffWorks: Bridges – lots of information about how bridges are built
• A Spotter’s Guide to Bridge Design – tons of info about different types of bridge designs
• Types of Bridges and how they distribute force of weight – this link has some very useful and simple diagrams
• Wikipedia’s page about bridges – this page gives a good overview of the main types of bridges and has some other useful links
  

  Zakim Bridge - Boston

Get an introduction to Newton’s Laws with this WebQuest!

Essential Question:  How do certain universal laws govern all motion?

Learning Target:  I can summarize each of Newton’s 3 Laws in my own words and give a real-world example of each

Instructions:

• Come up with a working definition of each of Newton’s 3 Laws (in your own words) and a real-world example for each that you can relate to
• Make a new post on your Edublog summarizing the 3 laws with a real world example and a picture for each
• Go to each of the following sites to find the information you need:

1. Newton’s 1st Law Animation – check it out and read the info
2. Newton’s 1st Law Summary – now go read the summary
3. Newton’s 2nd Law Animation - watch the animation
4. Newton’s 2nd Law Summary – summary of the 2nd law
5. Newton’s 3rd Law Animation – another animation!
6. Newton’s 3rd Law Summary - summary of the 3rd law
7. Hyperphysics - great concept webs and examples for all 3 laws

Here are a few sites to help you work with acceleration problems and be ready for our quiz tomorrow!

1.  Check out this animation: http://jersey.uoregon.edu/vlab/block/Block.html Play with the settings and make the cow move at different velocities & accelerations.  Pay particular attention to the graphs.  Look familiar?

2.  Good explanation and examples here:  http://library.thinkquest.org/10796/ch3/ch3.htm  Then take the quiz here: http://library.thinkquest.org/10796/ch3/ch3q.htm to check your knowledge!

3.  More practice problems here: http://www.physics247.com/physics-homework-help/speed-velocity-acceleration.php (do ones from section B – answers are at the bottom)
