Davis Creek Elementary 5th Grade Norway Connection

 The Nardo FIRST LEGO League team  has connected on Red Rover.

While the Davis Creek Students were building this year's play field they watched the movies from Nardo team
and talked with them through Rover Rover.

Tube worms live near. thermal vents.
The team worked on the research project from materials in the room and on the web.

Finding Thermal Vents

We used RoboLab Investigator to conduct tests using temperature sensors. 
Program level 4 begins as a template and can be modified to fit our investigation.
The programs on the RCX were uploaded using Ask RCX to be put back on later. 
Holding on the end of the temperature sensor "warms" it up the  so that the reading goes from low o high.
Water with an ice cube, tepid water, and warm water were used for the temperature readings. 
Two different types of temperature sensors were used. 
We used Protemp sensors for one program and LEGO temperature sensor for the other program. 
We wrote programs and uploaded the data from both types of sensors.
Here, our results are uploaded on a  graph.  When the the sensors was placed in the water warm, 
it took some time for them to cool off.  Our graph showed this information, as it 
started high and slowly went to a low.  The same thing was shown on the graph when 
the sensors began cold and were warmed up again, 
only instead it started low and gradually worked its way to a high. 
With the DCP ProTemp sensor we had to do some computation to get our results in degrees F.
Both sensors are being placed in the same temperature water to have the results compared.
 We loaded the saved programs back on to the RCX with no problems.
We working on building an arm/manipulator that 
would work to move the robot's sensor into the water.
The real world goal of this project is to have technology like this could 
be used to preserve our oceans.  By investigating and testing for thermal vents,
we can keep from dumping garbage and pollutants into the ocean in its most sensitive areas.
More Temperature Data

RoboLab Investigator is great for logging data from the temperature sensor
inside or outside.

We will work on the presentation more.
Thermal Vents

The thermal vents in the ocean have plants and animals that are different than other places.
To make sure that those places are not damaged by dumping garbage
it is important to know the areas where they are.
The LEGO RCX models doing scientific research with temperature sensors to do data logging.

The programs are getting organized and perfected.
Battery change!

We get a Red Rover break.

The Team and Robot

Work on the RoboLab FLL presentation is different in RoboLab 2.5.4.
( We are going to download patch C.)

The program for data logging is in the presentation.  Two programs together using light sensor is for FLL bot.

The real tube worms could be studied with a sub.
This is a model.
