6. How the Partnership Works
Scientists share their data collecting goals and data collecting requirements with the engineers. The engineers then research, design, build, test and deliver a technology solution to meet as many of the scientists requirements as possible based on the amount of money available for the project.

8. Class Discussion What was the scientists problem?
How to measure the big ocean? The scientists needed something to measure ocean depth, temperatures, salinity, movement in currents in deep water.
2. What were the scientists data collection requirements ?
The scientists data collection requirements were for the engineers to build an instrument that could:
Float at the top of the ocean
Sinks to deep water
Drift along with ocean currents
Rise up slowly to the ocean surface
Record temperature, salinity, current and depth information
Transmit data to a satellite and then to land.

9. Discussion, continued
What was the engineering solution to the scientists problem?
The “Argo Float” .

10. Activity 2: Sequencing Matters
Computer scientists program technologies to perform tasks. It is important the instructions be specific, in order and written in a language the technology can understand Assignment: Please sequence the Argo Float tasks below in correct order from 1 to 6 to function as the ocean scientists requested.
______ drift with the current for 9 days, measuring temperature and current speed.
______ on day one sink down 1oo0 meters
______ on day 9 sink to 2000 meters
______ repeat the commands every 10 days.
______ float at the surface and transmit data to a satellite and land. (antenna/computers)
______ on day 10 rise slowly to the surface measuring ocean temperature, salinity and depth.
