Answer:
The Algae-in-a-Bottle Experi
Explanation:
What materials are included? Three one-liter bottles of purified water; sugar; brewer’s yeast; silicone sealant; drill; 6-mm aquarium airline tubing; algae
Materials can be found at the following places: Purified water (supermarket), sugar (supermarket), brewer’s yeast (supermarket), silicone sealant (Walmart-type store); aquarium; airline (pet store); algae (pond or marsh or biological/scientific supply house); 10-15-10 liquid plant food (plant nursery or Internet)
Read about the conditions required for algae to grow, and formulate a hypothesis to predict whether giving algae supplemental carbon dioxide would be a feasible way to increase algae growth.
Collect some algae from a pond, marsh, swamp, swimming pool, fish aquarium, bird bath or other source. If you are unable to locate a natural source, contact a biological/scientific supply house (Google).
Add equivalent amounts of algae to two (clear plastic) bottles of purified water. Discard the bottle caps.
Add two drops of 10-15-10 liquid plant food to each bottle.
Pour out a small amount of water from a third bottle of purified water, leaving about an inch of air space at the top of the bottle. This bottle will be the carbon dioxide reactor.
Make a hole in the bottle cap of the reactor bottle that is just large enough to allow an aquarium airline to pass through it, then run the airline through the hole so that it extends into the free air space when the cap is on. Seal the airline to the top of the bottle cap with a silicone sealant.
