COMPARING THE ENERGY
EFFICIENCY OF DIFFERENT
LIGHT BULBS
Kit #206RS — Developed by SEPUP
Students use a unique piece of equipment to collect data and
compare the efficiencies of a small incandescent bulb and a
small LED bulb . They use their measurements to calculate the
efficiency of the bulbs to produce light by measuring how
much “waste” thermal energy is produced . They also compare
“lifetime costs” for different types of bulbs and consider the
trade-offs involved when deciding which type of bulb to
purchase .
Accommodates unlimited classes, each with 8 groups of four students.

INVESTIGATING
PHOTOVOLTAIC CELLS
Kit #220S — Developed by SEPUP

Students use photovoltaic cells to transform energy from
sunlight into electrical energy as they investigate solar
energy as an example of a renewable energy source . They
explore how to power a motor using the photovoltaic cells
and investigate some factors that affect the cells’ ability to
transform light energy into electricity . They then discuss the
advantages and disadvantages of using solar energy .
Accommodates unlimited classes, each with 6 groups
of four students.

SOIL NUTRIENTS AND FERTILIZERS

Kit #318S — Developed by SEPUP
Nitrogen is one of the essential plant nutrients found in soil .
Students measure the amount of nitrogen in several different
soils . They then examine the role of nitrogen in plant growth
and consider the effect of excess nutrients in an ecosystem .
Accommodates 8 groups of four students.
