Are you a "Supertaster?!" Materials Included: Premium Storage Case 100 Strips containing Phenylthiourea (PTC) 100 Strips containing Sodium Benzoate 100 Strips containing Thiourea 100 Strips containing NO chemical (Control) Key Vocabulary: Genotype: the specific genes found in DNA. Phenotype: the physical expression of genes (examples: eye color; tasting ability). Heredity: the passing of genetic information from parent to offspring. Punnett Square: a method for determining the qualitative chances of offspring inheriting certain genes from their parents. Just as humans have different levels of acuity in the senses of smell and sight, they also have differences in their ability to taste. Approximately 25% of Americans are considered "supertasters" and, of this subset, people have varying levels of "supertasting" ability. "Supertasters" are people who have the ability to taste the substance Phenylthiourea (PTC). Some people cannot taste this substance at all and others taste it quite distinctly. Whether or not a person is a supertaster (phenotype) is dependent on his/her genetics (genotype). For the purposes of this experiment, the dominant supertasting gene will be represented as "S" and the recessive supertasting gene will be represented as "s." Based on the genetics involved, there are four basic types of tasters à normal tasters (no S or s), standard supertasters (__ s), recessive supertasters (ss), and dominant supertasters (S__).

These test strips are a great way to monitor water without having to measure reagents

Manufacturer: Bel-Art Brand: SP Scienceware Model: B61891-0300

Available in a variety of models measuring specific gravity of heavy and light liquids in various ranges from 0.650 to 2.000 in accordance with the American Society of Testing Materials (ASTM) E100 standards. Specific gravity hydrometers are the most widely used hydrometer, common in industries such as food and beverage, chemistry, pharmacology, transportation, refrigeration and more. Made of lead free ballast and glass, these plain form hydrometers conform to the accuracy requirements of ASTM hydrometers as listed. Each is individually serialized and has a temperature standardization of 60 degrees F. ASTM Hydrometers are hand inspected by our U.S. quality team in our exclusive triple accredited/registered ISO/IEC 17025:2005 and A2LA Accredited Calibration Laboratory; internationally recognized and accepted by the signatory economies of the ILAC/MRA and located in our ISO 14001:2004 Environmental Management System registered facility. They are packaged with a multi-language (English, French, German, Italian, Portuguese, and Spanish) Statement of Accuracy indicating accuracy traceable to NIST. Note: ASTM hydrometers should be stored in a clean, dry, safe place. They should not be subjected to extreme temperatures.
