MIDDLE SCHOOL LIFE SCIENCEGENETICS, CONTINUEDWhy Do People Look Different? Student Laboratory KitTeach electrophoresis and DNA fingerprint-ing as students determine what members of a family look like. Investigated traits include hair and eye color and freckles. Separate simulated DNA by electrophoresis and colorful bands immediately appear in the gel, eliminating messy stains. Only one class period is required. 2 options available at flinnsci.com$47.70–$110.15Codon Bingo—Super Value GameThis lively codon bingo game adds fun to transcription and translation concepts and gets students using new words like uracil, thymine, adenine, guanine and cytosine. The flexibility of setting up the bingo cards provides an unlimited number of uses and creative alternative games. The easy-to-use translation wheel included with the game is a great teaching device.FB1112 I $17.55Karyotyping with Ideograms—Super Value KitStudents create chromosomal maps, match-ing homologous chromosomes to see if cells have numerical errors. Through physical manipulation, students learn about diseases and disorders related to genotype errors and discover links between DNA, chromo-somes, genotype and phenotype. Includes background information, procedures, work-sheets and 10 karyotypes. FB1858 I $14.25Baby Genes—Super Value KitWhy do some kids look like their parents and others don’t? Students select a sperm cell and egg for a potential child. After simulated fertilization, the baby is compared to its parents. A second child is formed from the same parents and compared to the first. Students see how different the children are from each other and their parents. FB1575 I $22.35Dihybrid Cross PosterPoster portrays common traits of base color and wing color for the familiar “budgie” bird. A pair of homozygous dominant and recessive parents is crossed to produce the heterozygous F1 generation. Chart of the possible offspring of the F2 generation clearly shows the expected 9:3:3:1 pheno-typic ratio and includes the genotype of each. Laminated, 24" x 36".FB1990 I $21.45More about genetics at flinnsci.com
