### A Bit of Engineering

The JOIDES Resolution is an amazing ship that contains all the equipment necessary to drill into the ocean floor for samples of rock and sediment: a derrick, drill pipe, drilling tools, and drill bits. Once the cylindrical core sample arrives on the rig floor, the drill crew passes the 10 m core to technicians. They, in turn, carry it to the catwalk, where it is cut into 1.5 m sections and labeled. After the core is brought up on deck, the technicians notify the rest of the crew by yelling: "CORE ON DECK!"

### Cracked Plates & Tectonics

In this activity, you’ll investigate dynamics in Earth’s crust that explain multiple Earth science phenomena.

### Deep-Sea Drilling

This activity enables students to estimate and calculate scales of distance and length as used by ocean drilling scientists.

### Drill Site Dilemma

This activity gives your students a glimpse at the difficulty of seafloor surveying, as well as the challenges the JOIDES Resolution faces during each expedition. Your students also will learn about latitude and longitude and plotting coordinates.

### Earth's Hydrologic Cycle

The ocean is the key element in Earth's hydrologic cycle (water cycle). Students will construct a simple model of the hydrologic cycle to help them visualize and understand the movement of liquid water and heat.

### Earth’s Magnetic Field

If you found yourself in the middle of the ocean, do you think you could find your way home? Sea turtles can, thanks in part to Earth’s magnetic field!

### Freddy the Fish

Human activities can have a detrimental effect on animal habitats. Young students can witness the effect of water pollution on river habitats.

### How Dangerous Are Tsunamis?

Imagine playing beside the ocean, when suddenly, the water drops. Where the water used to be, there are wriggling fish and ribbons of seaweed. What do you do?

### Hurricane Tracking

In this activity, plot data found on the National Hurricane Center website to track the path of the hurricane storms.

### Magnets at the Core

Learn about the Earth's magnetic poles and paleomagnetism in this activity from Consortium for Ocean Leadership.
