BIOLOGY & LIFE SCIENCES

INVESTIGATING AND
APPLYING GENETICS
Kit #603S — Developed by SEPUP
Students build their understanding of selective breeding
for desired traits in crops such as corn . They investigate the
outcomes of crosses of hybrid and dihybrid corn plants for
two unlinked genetic traits: corn kernel color and sweetness .
They use Punnett squares to predict the ratio of phenotypes
that will be produced by different crosses and analyze the
actual ratio of phenotypes of the second generation offspring .
A reading describes traditional selective breeding and modern
genetic engineering approaches to improving crops .
Accommodates unlimited classes, each with 16 groups of two
students.

CELL DIFFERENTIATION
AND GENE EXPRESSION

Kit #606S — Developed by SEPUP
Q: If all human body cells have the same genome, how does
this lead to so many different types of cells and cell products?
A: The expression of specific genes regulates cell
differentiation and cell functions .
In this highly illustrative activity, students investigate and
model gene expression as it relates to cell differentiation .
They consider how various physiological events affect gene
expression in each of four different cell types .
Accommodates unlimited classes, each with 6 groups of four students.

INVESTIGATING HUMAN
RESPIRATION
Kit #803S — Developed by SEPUP
Students explore the role of the respiratory system in the
regulation of gases in the blood . Students qualitatively
investigate the use of bromthymol blue (BTB) as an indicator .
They then quantitatively measure the amount of carbon
dioxide in their exhaled breath by using the indicator to
perform a simple titration .
Accommodates one class with 8 groups of four students.
