"Ward's® Thermochemistry In The Bag Inquiry Demonstration Activities"

Deuteromycete. Produces penicillin. Incubation temperature 25°C. Malt extract agar growth medium.

Ascomycete. Wine yeast: Used in fermentation activities. Incubation temperature 30°C. Sabouraud dextrose agar growth medium.

Cellular slime mold. Demonstrates amoeboid state, pseudoplasmodial state, and fruiting body, or sorocarp.

Use Sordaria fimicola to allow students to visualize the results of crossing over during cell division.

The nocturnal hermit crab uses “borrowed” shells to protect its relatively soft body, changing shells as it grows larger.

Mixed genera. Also known as scuds, amphipods are freshwater crustaceans.

Freshwater, Unicellular; pennate, with bilateral symmetry. Diatom or basic medium.

Characterized by shells (tests) made of silica, in two parts.

Freshwater; elongated, biflagellate cells that form globular colonies; gelatinous sheath absent.

Live Cultures are supplied with media in 16 x 125 mm tubes, 2 oz. jars, or 8 oz. jars. Fast delivery is available directly from our laboratory. Please specify a delivery date.

Each culture shipment is prepared in our laboratories and includes the "Working with Algae & Cyanobacteria" manual which contains detailed instructions for subculturing and use.

Canadian Customers:
CFIA and PHAC regulations require customers to submit a completed inspection checklist and signed statement of facilities compliance before receiving certain cultures. A customer service representative will contact you if documentation is required.

Marine; Small Motile Cells with the Transverse Furrow Located Near the Apex.

Freshwater. Unicellular. Soil-water medium. Characterized by two flagella (one inside a groove at right angles to the other); most also have tests made of cellulose and are encrusted with silica.

Usually found in freshwater and mosses, this organism has a hard umbrella shaped shell or "test", out of which finger-like pseudopodia project.

Demonstrate amoeba structure, locomotion, and feeding behavior.

Members of the Pelomyxa genus look very much like Amoeba. Pelomyxa, however, have many nuclei, whereas Amoeba have only one.

Paramecium caudatum is a common protist that inhabits a variety of aquatic ecosystems.

Black Planaria are a flatworm commonly used in science fair projects. They do not bite and move very slowly, making them easy for young students to observe.

Philodina sp. Easy to culture and easy to examine under a microscope because of the lack of a lorica (shell), these typical rotifers are perfect for general study. Culture instructions are included.
