Lead in Water—
Student Laboratory Kit
Challenge your students to understand the potential harm that lead presents to their lives and the environment. In this lab activity, students test simulated environmental water samples for the presence of lead. Complete for 30 students working individually. Super Value Kit is complete for 5 classes of 30 students working individually.
FB1922 | Student Laboratory Kit | $51.80 FB2066 | Super Value Kit | $71.15
Testing Pollution in Tap Water— Student Laboratory Kit
Students will determine the quality of tap water and measure pollution levels. This easy- to-use kit includes tests for chlorine, total hardness, iron, copper and pH. Single class
kits are for 30 students working in pairs. Super Value Kits are for 5 classes of 30 students work- ing in pairs.
AP5955 | Student Laboratory Kit | $86.75 AP5956 | Super Value Kit | $196.25
Measuring Dew Point and Relative Humidity—
Student Laboratory Kit
Students will make direct dew point obser- vation and sling psychrometer dew point measurements, perform a relative humidity calculation and obtain a sling psychrometer relative humidity measurement. Complete for 30 students working in pairs.
AP6449 | $144.45
Density of the Earth—
Student Laboratory Kit
In this activity, students use water displace- ment to make smaller scale measurements of the density of rocks. Averaging and compar- ing the results gives students insight into how the density and mass of the Earth are calculated. Complete for 30 students work- ing in pairs.
AP6738 | $73.15
Phosphates Test Kit,
Color Comparison
Students can measure phosphate levels in water by using this fast and efficient tech- nique. Simply snap one of the self-filling test ampules in the sample cup and compare that to a set of color standards. A refill kit
is available separately. Complete for 30 students working individually.
FB0027 | Phosphate Test Kit | $70.30 FB0028 | Refill Kit | $32.45
Lead in Soil—
Student Laboratory Kit
Students run an aqueous extraction on a dark, rich soil only to find that it may contain detectable levels of lead. The experiment provides a realistic analysis of contaminated soil as students learn about the toxicology of lead on humans and historical sources
of lead contamination, such as lead-based paint, leaded gasoline and foundry deposits. Complete for 30 students working in pairs. FB1923 | $22.30
