Biology
Photosynthesis lamp, LED, full spectrum, 20 W
This full-spectrum LED light is designed for classroom plant experiments. It features two flexible arms with adjustable heads, a clamp for attaching to a table edge or windowsill, and a timer function that can be set to 3, 6, or 12 hours. The light spectrum mimics sunlight in the 380–800 nm range, and the brightness can be adjusted in ten levels. The light operates on 100–240 V and supports plant experiments all year round.

Physics
Physical Pendulum – Wireless
In this experiment, the period of a physical pendulum, a narrow bar, is determined as a function of the distance of the pivot from the center of mass. A computer model of the system is developed, which allows the student to vary the physical parameters of the model (gravity, length, c.m. position) to match the data. This makes it possible to obtain values for the physical parameters without direct measurement.
