We introduced the students to Legos. Many students already knew about Legos and but were very intrigued by the Robotics part of Legos. I gave an introduction to some key vocabulary words for Legos. These words help us to comunicate. I gave them such words as axel, brick and beam.
Then the students were directed to build a "car that rolls." One thing that is so exciting about students for me is how many ways students will come up with to solve a problem. The problem was simple- Build a car that rolls.
Of course, because these students are New York City students, they quickly came up with solutions that met the critieria of the mini-lesson. The students worked in groups of two. They had to communicate effectively and build it together.
Let's take a look at some of the solutions. Later, I will have this group back. I would really like to have this bunch for next year's team and class. I can tell they will be amazing!

I would to hear about these types of discoveries.

See guys, even international car companie have difficulty with producing an affordable alternative fuel auto. Maybe the sales are low due to a combination of factors. Isn't the Toyota Prius making sales history?
Why do you think the Prius sales are taking off and the Electric Honda Accord sales slumped to the point that Honda had to cancel sales altogether?
I respect my students' attempts at making an alternative-power source Lego Robot. Don't give up just yet! They are having much difficulty with making a working model but are learning a tremendous amount!
I will consider a whole Google thing for apps, pix, blogs and account later.
You will need to go to OpenOffice.org to get the application that will open the directions!
Box.net is a free storage area for users on the web.
OpenOffice is a free suite of office products that look and work like Word and Powerpoint. I thought a treasure hunt might be a cool way to get people to take a look at some helpful technology.
The directions on how to win the prizes are outlined in the doc on the Box account.

Three groups tested their Lego Robots on the ramp in the classroom. I observed all groups running their robots up the ramp. I was pleased that we have more than one group running tests.
I observed the following:
- each group expressing their disappointment about how far up the ramp each robot was able to climb.
- each group speculating about how to fix the robot to make it climb higher.
- very few written observations being entered by the teams.
The Science comes from writing down what you are attempting. Describe the results. Describe a plan of action to redesign the robot. Run it again. Log the new observations, such as "It went 5 cnetimeters farther up the ramp. We change the tires by doubling up the tires on each side of the axle."
Tell your journal why you think an attempt or a redign was successful or not. This reveals your learning.
I would like a few comments concerning the ramp, drive trains, worm gears, traction, slipping and anything else that goes on when a robot is climbing!
