Each plastic-formed map in this set of seven is colored and detailed to best relate a variety of topographical features to the underlying geology, including erosional/depositional environments. The included study guide gives a synopsis of each region, with keyed photos noting important features. Contents: Yakima, WA; Hoquiam, WA/OR; Portland, ME/NH, Harrisburg, PA; Grand Canyon, AZ; Death Valley, CA/NV; and Monterey, CA. Scale: 1:250,000. Size: 33″L x 21″W.

ScholAR Study of the Properties of Buffer Solution Kit — $208.00
Demonstrate the characteristics and functions of buffer solution with this student experiment. Students prepare three buffer solutions with different pH values. These solutions are then exposed to small amounts of acids or bases, and students examine any variance in the buffer pH after exposure. Water is also exposed to the same acids and bases, as a means of comparison, and student hypothesize the effects of the acids and bases on the water. Kit includes necessary materials, chemicals, and instructions...

VWR™ Filtering Flasks, 1000 mL — $239.34
Our high-quality borosilicate filtering flasks meet ASTM standards and are a great value. Designed for strength under pressure, the flasks feature a side arm, marking spot, and white enamel graduations.

Map Projection Model — $117.50
Three map types: cylindrical, conical, and azimuthal, are represented on transparent plastic. When the maps are placed over the globe, it’s easy to see how distortions on the flat maps occur. The entire model can be written on and cleaned repeatedly, and the cone and cylinder maps can be unsnapped for flat viewing. It also comes with a study guide. Size of globe: 8″ dia.

ScholAR Freezing Point Depression to Determine Molecular Mass Lab Activity — $43.00
By measuring one of the properties that changes when a solute is dissolved in a solvent, in this case the freezing point, and comparing it to the freezing point of the pure solvent, it is possible to determine the solute’s molecular mass. With this experiment, students measure the freezing point using a melting point apparatus. This activity can be completed in 60–90 minutes, depending on the number of repetitions required, and comes with enough materials for 15 setups.

EdvoCycler — $1,795.00
Utilizing modern peltier heating and cooling, the EdvoCycler outperforms other thermal cyclers in both temperature, accuracy, and speed. It includes a heated, oil-free lid and an easy-to-use, built-in computer interface. Students can easily perform PCR experiments with technology not often found in similarly priced thermal cyclers. Unit holds up to twenty-five 0.2mL tubes, will heat to 98°C, and cool to 4°C with an accuracy of ±0.1. Includes one year warranty.
