Your Name: Lorene Fallon

Concepts Addressed:

What are deep sea thermal vents

Where thermal vents are found

Lab Goals:

To identify the black thermal vents and the white thermal vents

To identify how deep sea thermal vents are structured

Lab Objectives:

  • Labeling thermal vents
  • Identifying the two different thermal vents
  • Duplicating the action of thermal vents

Benchmark(s) Addressed:

K.3S.2 Make observations about the natural world.

K.4 Engineering Design: Engineering design is used to design and build things.

K.4D.1 Create structures using natural or designed materials and simple tools.

1.1 Structure and Function: Living and non-living things have characteristics and properties.

1.1E.1 Examine characteristics and physical properties of Earth materials.

1.3 Scientific Inquiry: Science explores the natural world using evidence from observations.

1.3S.1 Identify and use tools to make careful observations and answer questions about the natural world.

1.3S.2 Record observations with pictures, numbers, or written statements.

2.4 Engineering Design: Engineering design is a process used to design and build things to solve problems or address needs.

Materials and Costs:

List the equipment and non-consumable material and estimated cost of each set

Ketchup and mustard bottles $1.00

Clear container $8.00

Tubing $5.00

Water free

Estimated total, one-time, start-up cost: $14.00

Times number of sets needed: _____.___

List the consumable supplies and estimated cost for presenting to a class of 30 students

Clay $8.00

Salt $2.00

Ice $1.50

White Food coloring $4.00

Black food coloring $3.00

Estimated total of consumable supplies: $18.50

Time:

  • Preparation time:
  • If the teacher make the vents in the containers about 2 hours
  • If the students make their own vents about 30 min.
  • Instruction time: 30 min
  • Clean-up time: 15 min
  • If pouring water out of containers into sink, be watchful not to include the clay. Clay will catch in the U joint and cause a clog that is hard to clean out.

Assessment (include all assessment materials):

  • Students complete the handout (at the end of this lesson).

Procedure:

Clay about 2 to 3 lb per group

Red (ketchup) and yellow (mustard) bottles per group

1 clear container per group

Tubing two pieces about 1 ½ foot long per group

Black and white food coloring

Salt one cup for every gallon of water

One bag of ice

In the red (ketchup) container add one drop of black food coloring and fill ¾th full of warm or hot water put top on tight and shake to mix. In yellow (mustard) container add one drop of white food coloring and fill 3/4th full of warm or hot water put top on tight and shake to mix. (Note water does not need to be extremely hot)

Make two thermal vents and the ocean floor with the clay and tubing in the clear container. The thermal vents need to be made around the tube and placed into the container, using the remainder of the clay cover the bottom of the container for the ocean floor. The tube is the crack in the earth.

Make Ocean water

In a separate container mix one cup of salt and 3 quarts of water mix till salt is dissolved add 1 quart of ice and mix till ice is dissolved.

Add the ocean water to the container that has the thermal vents ready to go.

Attach the yellow container to one tube and the red container to the other tube. Lift the bottles slowly and watch.

Name ______

What kind of thermal vent does the yellow container make ______.

What kind of thermal vent does the red container make______.

Draw and label your container.

Black thermal vent white thermal vent ocean floor crack in the earth
