DNA Activity Model
Affordable, easy-to-understand replica of the “molecule
of life.” At last, a realistic DNA model that fits within your
budget! Your students will construct their own double
helix model complete with cytosine, adenine, guanine, and
thymine nucleic acid bases connecting phosphate strands
and a center rod representing hydrogen bonds. Easy-toassemble,
three-dimensional model is made of durable plastic
components for years of classroom use. Colour-coded
parts feature specially-shaped ends to ensure proper base
pair alignment and can be unzipped to demonstrate DNA
replication. Includes comprehensive, illustrated student and
teacher guides. Comes with sturdy, metal base for easy rotation
and classroom display. 19" H x 7½" D. Sh. wt. 1.95 kgs.
SB37360M — $85.10
Challenge your students to determine
the phenotype, genotype,
and frequency of easily observed
human traits and identify the
dominant and recessive genes for
each trait. Activities include determining
unique traits with tastetest
paper, constructing a family
pedigree, and using Punnett
squares to predict ways genes
combine during fertilization.
Enough materials for 40 students.
Grades 7—10. Sh. wt. 1.25 lbs.
SB47591M — $29.70
STICK TO SCIENCE — Genetic Cards
Solve the puzzle of how genes are inherited and sometimes appear or disappear in
families. Using these 36 magnetic shapes representing males and females with the
three possible genetic combinations (affected, carriers, or not affected), all types of
inheritance (complete dominance, incomplete dominance whether autosomal or sex
linked) can be investigated. The teacher’s guide has actual case studies and lesson
outlines as well as reproducible student work sheets.

Modern Genetics Poster
A thorough, visual overview of the structure and
function of chromosomes, genes, and DNA. Also
provides a step-by-step procedure for DNA fingerprinting.
Large reference poster features detailed
illustrations to facilitate comprehension of important
standards-based concepts. Measures 23" x 35".
Laminated. Grades 6—10. Sh. wt. 0.63 lbs.
SB47614M — $23.75
Human Genetics Disorders Poster
Presents a detailed view of all 23 human chromosome
pairs and the location of the genes which
cause the most common genetic disorders discovered
to date. Shows breast cancer, melanoma,
deafness, muscular dystrophy, Parkinson’s disease,
Tay-Sachs disease, cystic fibrosis, colour blindness,
and others. Also presents four karyotypes representing
a healthy male, healthy female, Down Syndrome,
and Turner Syndrome. Laminated. 23" x 35". Sh. wt.
0.23 kgs.
SB35354M Laminated — $25.60
K’NEX ® DNA, Replication & Transcription Set
Wonderfully flexible set allows students to build and learn using models that demonstrate
phosphate groups, deoxyribose/ribose sugars, colour-coded hydrogen
bonds, four codons, and colour-coded nucleotides. Builds seven different DNA and
mRNA molecules. Build any one from 19 combinations at once. Pieces easily unsnap
for replication and transcription activities. Includes: 521 K’NEX ® pieces and a 24-page,
full-colour building instruction booklet packed in a strong, stackable, plastic storage
case with movable dividers and transparent lockable lid. Grades 5—9. Sh. wt. 1.99 kgs.
Curriculum CD is now included with set.

Genes
and Probability Lab
Study the patterns of inheritance
and genetic probability
of easily observed and tested
traits. Students use game-like
exercises to explore gametogenesis
and fertilization; monohybrid
and dihybrid crosses;
laws of dominance, segregation,
and recombination; independent
assortment; and
other fundamental principles of
genetics. Materials
for 40 students. Grades 7-10. Sh.
