Synthetic owl pellets provide a safe, realistic, and reusable dissection experience, featuring hand-crafted replicas of skeletons and carefully imitated contents that closely mimic natural owl pellets.

This pH electrode is a plastic body, double junction, gel filled pH electrode with a built-in temperature sensor for temperature compensated measurements in a single probe design.

The simpleGEN is an easy-to-build AC generator that allows students to explore the basics of electrical generator design. With the simpleGEN, you can demonstrate Faraday’s law, light LEDs, and perform experiments that explore how coils, magnets, and rotation affect electrical generation. With some quick modifications, you will be able to convert your generator to a simple motor and explore additional variables. You can also take your experiments to the next level by converting your simpleGEN into a wind turbine nacelle.
