HEREDITY AND ENVIRONMENT
Kit #77
By germinating hybrid tobacco seeds first in darkness and then
in light, students make interesting observations . 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
Lab-Aids kit to correlate heredity with environmental influences.
Accommodates one class with 15 groups of two students.

pH MEASUREMENTS AND
INDICATORS

Kit #81R
In this very popular Applied Science Concept Kit, students
perform a series of colorful tests that help them to develop
a better understanding of pH, its relationship to acids and
®
bases, and its effect on indicator dyes . Using a Lab-Aids
Chemplate and universal indicator, each student creates
®
their own pH color guide . This color guide is then used
to identify the pH of three unknown solutions, which are
provided in this kit .
Accommodates three classes, each with 15 groups of two students.

PROPERTIES OF ACIDS
AND BASES EXPERIMENT
Kit #82
This Applied Science Concepts Kit provides a completely
safe and convenient method for students to study, test,
and observe the characteristic properties of acids and
bases . Students perform a total of seven different activities .
Activities incorporate the Lab-Aids Chemplate . This unique
®
®
lab tool eliminates the need for glassware and provides a
semi-micro environment in any classroom .
Accommodates three classes, each with 12 groups of two students.
