Animals and Zoology— Animal Study Kits
Drosophila Basics—
Studying the Monohybrid Cross—
Student Laboratory Kit
Don’t leave genetics experiments to chance! Guarantee student success with this introductory-level lab kit, which includes a detailed tech- niques guide. Drosophila, the common fruit fly, is as an ideal organism to study the basic laws of heredity. Students will analyze pathway inheritance patterns by performing a monohybrid cross between wild- type and mutant strains.
Complete for 8 student groups. Wild­type and sepia Drosophila are required and available separately. Drosophila cultures should be ordered separately to arrive two weeks prior to the scheduled use date.
Drosophila Laboratory Equipment Kit
All the basic material requirements for conducting experiments with Drosophila. A convenient and economical package including 30 vials, 30 foam plugs, 30 pieces of vial netting, instant culture medium, sorting brushes and a copy of the Flinn Drosophila Guide. Live cultures and etherizers/anesthetizers must be purchased separately.
Materials provided for 24 to 30 students working individually or in pairs.
Metabolism Experiment
Introductory metabolism studies with living organisms are greatly simplified when using the unique metabolism chambers in this kit. Students can observe small living organisms and draw correlations between the size of an organism, temperature of the environment, and oxygen consumption. Sow bugs, meal worms, snails, crickets, worms or germinating seeds make excellent subjects for measuring the rate of oxygen consumption. After data has been collected students calculate the respiratory rate of the organism and determine the cubic cm of oxygen per kg per hour. An excellent lab with high student interest and hands-on involvement.
The kit includes detailed instructions, two unbreakable metabolism chambers, and all of the chemicals and equipment needed for two student teams. Living organisms are sold separately.

Prepare Infusion Media for Protozoans
Culture media made by soaking or heating fresh or dried organic (usually plant) material in water are known as “infusions.” Organic materials used include hay, wheat seed, rice and oat flakes—either individually or in some combination.
The source of the water used is critical. Spring water, well water and filtered water from unpolluted streams or ponds are the best choices. The ratio of organic material should be approximately 7 grams (0.25 ounces) per liter.
To pre-treat the organic material, place it in boiling water for one to two minutes, remove it and maintain it under sterile conditions until it is needed. When you are ready to set up the cultures, pour one inch of water (pre-boiled) into a culture dish (31⁄2"–41⁄2" diameter) and add the organic material.
Some specific examples are:
Hay/Rice Medium—To the dish of pre-boiled water add two or three grains of rice and three small (2") pieces of timothy hay. Let stand, uncovered, 24 to 48 hours and inoculate. Recommended for all types of amoeba, volvox and ciliates.
Wheat Medium—To the dish of pre-boiled water add four to six grains of pre-treated wheat seed and let stand, uncovered, 24 to 48 hours. Inoculate with Blepharisma, all types of Paramecia, Stentor or Vorticella.
For culturing non-specific organisms, prepared infusions can be inoculated with water (a few mL) from any nearby pond, stream or puddle. See what develops!
