Part II: Multibeam Mapping by NOAA Classroom - 60-120 minutes

This activity is an opportunity for students to connect to underwater research currently taking place.
Activity Preparation 1. Prepare cardboard box approximately 10 x 10 x 6 inches.
2. Mark a grid of 1-inch squares on the top of the box. Make a hole at each junction point large enough so that the pencil or dowel can easily be inserted. TIP: Make a hole in the cardboard with a drill; then enlarge the hole with a sharpened pencil or dowel.
3. Label each row of holes with a number (1-9), and each column of holes with a letter (A-I).
4. Prepare a “mystery landscape” in the bottom of each box. This can be student or teacher generated. A sailboat shipwreck maybe a good sailing tie in.
5. Cut out the Sounding Rod Scales, so that each student has two scales. If you are using the uncolored scales, color each interval with a colored pencil using the colored scales as a guide. Tape each scale onto a pencil or dowel to make two Sounding Rods for each student. The bottom of the scale should be even with one end of the pencil or dowel.
6. If students are doing this step, they should keep their work out of the sight of other groups. Mix plaster of Paris, and pour a 1 – 2 cm thick layer into the bottom of each box. Pile up some of the plaster to make irregular mounds that simulate rough topography.
7. Do not completely cover the bottom of the box, because that will reduce the overall depth range, and we want a lot of variation in these landscapes! Allow plaster to harden.
8. Take a moment to think about all of the information we have covered in modules 1-10. You have been scientists, engineers, mathematicians, and sailors. Today, you will become an explorer.
