  1. Geologic Sequestration In this lab, you will conduct an experiment to learn about the method of geologic carbon sequestration.

  2. Materials (per lab group): • 100 ml of vinegar • 2 -- #6, two-hole rubber stopper with plastic tubes • 2 -- 250-ml flask • 2 lengths of rubber tubing, 45 cm long each • Safety glasses for each student • 1 -- 250 ml beaker • 1—50 mL beaker • 1 -- 30 ml syringe (no needle) • Supply of water • Yellow food color to represent oil • Box of baking soda • Several straws or rigid plastic tubing • 30 copies of Geologic Sequestration-Student Sheet

  3. Put on your safety glasses. Then place enough baking soda in the flask to cover the bottom.

  4. Tubing Syringe & Vinegar Rubber stopper Two Straws Flask Baking Soda Collecting Tank Oil Reservoir Add 100 mL of “oil” to the 2nd flask. Place rubber stoppers and rubber tubing on the flasks. Attach one rubber tubing to the long plastic straw and place the other end inside the beaker.

  5. Pour about 40 mL of vinegar into a 50 mL beaker.

  6. Slowly add 10 mL of vinegar to the baking soda. The gas this is being produced (CO2) will push oil out of the underground deposit and into the collecting tank.

  7. Slowly add more vinegar to the baking soda until the oil stops flowing into the collecting tank.

  8. When you have finished this activity, clean up your materials and place the materials back where you found them.
