What does the ocean floor look like? Be inspired by scientist and map builder, Marie Tharp and make your own relief map of the world. Represent the topography or physical features on land and on the ocean floor with easy DIY shaving cream paint. Introduce kids to the fun of mapping, with this hands-on ocean map activity. We love do-able and simple geology for kids!
OCEAN FLOOR ACTIVITY FOR KIDS
WHO WAS MARIE THARP?
Marie Tharp was an American geologist and cartographer who along with Bruce Heezen, created the first scientific map of the Atlantic Ocean floor. A cartographer is a person who draws or produces maps. Tharp’s work revealed the detailed topography or physical features and 3D landscape of the ocean floor.
Her work proved the controversial theory of plate tectonics. Plate tectonics was a theory that the earth’s land masses shift and move over time. Tharp’s discovery of a rift valley showed that the sea floor was spreading—was initially dismissed as “girl talk.”

Marie said she never would have gotten the chance to study geology if it hadn’t been for Pearl Harbor. Girls were needed to fill the jobs left open because the men were off fighting in the war.

INSTRUCTIONS
STEP 1: Print the world map template.
STEP 2: Mix food coloring and shaving cream to make the colors for your map.
STEP 3: Paint the land first. The colors you use are related to topographic height, with green at the lowest level, rising through yellow and tan, to white at the highest elevations.
STEP 4: Next paint the water. For the ridges and trenches of the ocean floor, and the shallow and deep water, you can use varying colors of blue.
STEP 5. Put aside your finished map to dry. Make sure to talk about what the different colors represent on your map!
