GENETIC EQUILIBRIUM AND
NATURAL SELECTION
Kit #76
Students study the principles of genetic equilibrium and
natural selection as a process of evolution using this
interesting kit . A simulation is used to develop insights about
the genetic process involved when natural selection operates
within a population in genetic equilibrium . Students use the
data collected in the Hardy-Weinberg Equilibrium to better
understand the actual complexity of natural selection .
Accommodates unlimited classes, each with 15 groups of two
students.

HEREDITY AND ENVIRONMENT

Kit #77
By germinating hybrid tobacco seeds first in darkness and
then in light, students make interesting observations using this
challenging kit . Students set up controlled experiments that provide
mathematical data to test their theoretical genetic hypotheses
about heredity and the factors determined by the environment .
They see how a recessive trait becomes evident . Students also
germinate the hybrid tobacco seeds with one normal and one
albino gene, stimulate shoot production, examine the relationship
of the dominant gene (chlorophyll production) to the recessive
gene and make conclusions concerning the genotype relevant to a
visible phenotype . This is an excellent kit to correlate heredity with
environmental influences.
Accommodates one class with 15 groups of two students.

STRAWBERRY DNA EXTRACTION
Kit #79
Teach biotechnology without the technology in your
classroom . This kit is a “low-tech”, hands-on solution to
presenting some high-tech topics . Extract DNA from
strawberries and examine some physical properties . This
complete classroom kit provides everything needed (except
strawberries) along with specially prepared cell lysating
solutions and DNA precipitating . This allows students to
easily extract DNA by first crushing the strawberry, then
lysing to release the cell components and finally precipitating
and viewing the DNA after spooling the DNA on a splint .
Accommodates two classes, each with 8 groups of four students.
