SIMULATING THRESHOLD EFFECTS
OF SOIL pH ON HYDRANGEA

Kit #320
Students model how hydrangea plants are affected by soil
pH . The use of a simulation allows students to determine the
effect of agricultural lime on hydrangea flower color. Students
use the data obtained from the simulation to determine the
positive and negative threshold doses for “agricultural lime .”
They also reflect upon the results to decide whether they
have sufficient data to recommend an optimal level of lime
treatment to produce healthy plants with large, pink flowers.
Accommodates three classes, each with 6 groups of four students.

COPPER MINING AND EXTRACTION
Kit #440S — Developed by SEPUP
Copper and other raw materials contribute to our
technological lifestyle, but the byproducts of extracting
copper from ore are potential toxic wastes . In this activity,
students explore the properties of copper and copper ore .
They conduct two reactions used to extract and recover
copper from the ore .
This process introduces single and double replacement
reactions . Students also consider the wastes produced by the
extraction process .
Accommodates 8 groups of four students.
