"Preserved+Plant+Materials"

Demonstrates thermal conductivity differences between materials.

Perfect for density experiments, use this set determine the mass and volume of each sample and graph the mass versus volume. The slope of the straight line that results is the density of the material.

Accessories for Casualty Simulation Kit 3

This STEM-based curriculum kit accents the scientific method and independent inquiry featuring hands-on learning materials and exciting interactive digital content that can be accessed on a computer, tablet, or mobile device.

Field-collected material; species not identified.

Engaging, ready-to-use learning centers for the classroom, after school programs or home practice, for review of standards-based topics and test preparation!

On bark. Field-collected material; species not identified.

Versatile teaching kit contains enough materials for the whole classroom to learn about and experiment with a variety of pulley configurations. Because these activities are hands-on, students get a real feel for the forces at work.

Accessories for Van de Graaff.

Zoom in on the key topics in cell biology with these colorful and innovative posters.

Construct an acutal fractal in the classroom. This HexaPlex set combines fractals and tessellations in physical puzzle materials for students to build their own visual key to symmetry, iteration, angles, area and scaling, polyhexes, and number series.

Cladonia or reindeer moss. Field-collected material.

Educational Materials, Wooden, 1" Dia.

Nine level conductivity meter shows the relative conductivity/resistance of liquids and solids. As the conductivity of the tested material increases, the number of glowing red LEDs will increase to a maximum of 8, which indicates a very good conductor. There will be zero glowing red LEDs if the material has a very low electrical conductivity (is a good insulator).

Meets AP Science Practices 1, 2, 3, 6, and 7

Gain an understanding of materials science and liquid crustals and how they can be used in a variety of technologies.
