Technology testing

Design Challenge:

Build-A-Bot

Learners will discuss, research, design, build, and showcase a model ocean exploration device from LEGO bricks or other found materials. Work in teams to research the variety of ocean exploration devices including the tools on E/V Nautilus but don't forget the Build-A-Bot Inspiration Slidedeck for more ideas!  Brainstorm what type of tool learners want to make, what their device will do, and why there is a need for this tool. 

STEM Learning Module:

Save Yourself - Sacrificial Anodes

Students will investigate how rates of chemical reaction rates - galvanic corrosion - vary among different metal types with and without the addition of sacrificial metal. This is a redox reaction example suited well for upper-level students. Students will learn how anodes protect E/V Nautilus and the ROVs Hercules and Argus from corrosion.

STEM Learning Module:

Work It With Circuits

Use this as an introduction to the Sensor Technology Series or a stand-alone basic electricity lesson. Students will examine how electricity flows using conductive and resistive materials to build a basic circuit, drawing diagrams, and using models to explain what makes an electric circuit complete. For an extra challenge, students can design series and parallel circuits and define the differences.

STEM Learning Module:

Sense Your Surroundings

Building off the Can You Sense It module, students will design a research question they can answer using an Arduino sensor. Challenge groups to identify questions that can be answered with data on environmental variables collected from a sensor deployed within the school or community. A provided resource bank guides students through sensor platform design including instructions to add data logging capacity to the platform.

Sensor Technology Series: Module 3

STEM Learning Module:

Can You Sense It?

This module guides students through the incorporation of a simple sensor into the Arduino basics covered in the Codes & Controllers module. Students will learn basic programming techniques to build a proximity sensor, design their own experimental trials for the sensor, and collect and analyze data from the trials. Other types of simple sensors (temperature, humidity, environmental gases) could be substituted into this lesson. Students will read about how sensor technology is used on Nautilus.

STEM Learning Module:

Codes & Controllers

Ready to introduce students to coding & microcontroller technology? Use this easy-to-follow module to teach students hardware, software & coding basics using an Arduino microcontroller. Groups will analyze basic coding language, manipulate a provided, pre-written code to change output variables, practice building a basic circuit on a breadboard, and demonstrate learning by writing a blinking SOS code.  

Sensor Technology Series: Module 1

STEM Learning Module:

Stitching Together a Seafloor

Introduce students to the applications of photomosaics relating to maritime history and archaeology. Students will work in small groups to complete photomosaic puzzles of real seafloor scenes by recognizing and comparing unique features among image squares. At the end of the activity, students will respond to conclusion questions demonstrating their understanding of the concepts involved with this lesson and be able to relate these concepts to real-world ocean exploration.

STEM Learning Module:

CTD Analysis

A CTD sensor measures the Conductivity, Temperature, and Depth of the water surrounding ROV Hercules while exploring across the seafloor and through the water column. This module introduces students to graphing using real CTD data collected from E/V Nautilus. Students will plot temperature, salinity, and water pressure measurements from different depths and then build analysis skills observing and identifying patterns in the variables’ relationships across depth.
