ENVIRONMENTAL SCIENCE

BIOFUELS: INVESTIGATING ETHANOL
PRODUCTION AND COMBUSTION
Kit #39S — Developed by SEPUP
This activity includes three major parts .
• Investigation One - students observe a demonstration of the
fermentation of corn and cane sugar, the two food sources used
most commonly to produce ethanol, and the distillation of the
fermented stillage to produce fuel .
• Investigation Two - students investigate the energy released by the
combustion of ethanol and kerosene and compare the results .
• Investigation Three - students measure and compare two by-
products - CO 2 and particulate matter - of the two fuels . Students
compare results and discuss the trade-offs of biofuels and fossil fuels
as sources of energy .
Accommodates five classes, each with 6 groups of four students.

PLANT CLONING:
PROPAGATING CUTTINGS

Kit #60R
Specially designed materials make it easy to clone plants
through the process known as asexual plant propagation .
This activity requires no special facilities because the small,
®
easy-to-use Lab-Aids Greenhouses automatically control
many environmental conditions and allow students to readily
observe plant physiology .
Accommodates one class with 6 groups of four students.

NATURAL SELECTION: VARIATION
IN SPECIES AND NORMAL
DISTRIBUTION
Kit #74R
Variation in species and normal distribution are brought to life with
this Lab-Aids kit. Students use our exclusive Variation Profile Tubes
to sort a variety of physical characteristics in sunflower seeds. They
gain experience in constructing visual graphs, histograms, and linear
graphs from data collected by the entire class . The idea that greater
validity of information gathered from a large sample versus a smaller
sample is illustrated beautifully by comparing class results in the
Variation Profile Tubes to the student’s own histograms and graphs.
Accommodates unlimited classes, each with 30 groups
of one to two students.
